Your Components are probably FAKE! Soooo is that BAD?

idk why they called it fake when actually term supposed to be used as refurbish...repaired is correct term of selling less than original new but don't expect to last long time as original

washing machines with japan capacitors tend to last longer

I've basically never experienced this in any real way after several decades. The only time I received "counterfeits" they were simply just the wrong part, not even labeled as the correct part. A few failed chips here and there. Maybe this is a concern for high-end components, but working with consumer/pro audio projects, I've basically never had a real issue and I am highly skeptical of those that claim this is a rampant problem. Is it, or was yr design f'd up and you haven't figured it out, found a few out of spec chips, and leaped to conclusions? My experience is so contrary it just leaves me scratching my head. But I don't just order parts from anywhere in China, or jump at the very cheapest deals. I dunno what other people are doing.

okay, so the big takeaway is that fake components aren't nessecarily bad, but they could be, and that's a problem if you're working with low-tolerance applications?

Thank china for flooding the market with garbage through sites like amazon and ebay.......neither site checks the quaity or validity of the products they list and sell

Especially important for Newbees (like me). Have many projects that worked fine for a while and then mysteriously started malfunctioning. Could be my fault or cheap (maybe fake) components!

Why do you add an "s" to every word, even though it doesn't need it?

"This is a mosfetSSSS". "This circuitSS".

I loved the way you recommended a cheap chinese tester to test cheap chinese components.

It was a very well done and informative video. But as a component resseller I yet have a few remarks to make : most very common components have now been manufactured for more than 30 years. Which means that the industrial tooling equipment for it had the occasion to get used and sold, depending on the component it's actually not always that "hard" to make : for the LM324 you were talking about I have at least 10 different trustable providers for that same component and I could hook you up with a company that refurbish tooling for it if you ever wanted to make your own ones... The manufacturing process of those is OLD TECH by now.
On the other hand, there is more often than not a vast array of substitution choices for most common components (diodes, transistors, old or generic IC's, mosfets, opto's, triacs, voltage regulators, you name it). So just please don't make it look like there was only ONE valid replacement from ONE single manufacturer, because I can tell by experience we wouldn't see much western individuals get access to any components at all with that mindset. Even if given access to Farnell like you have (which they don't, and Farnell like all their western competitors are still VERY limited compared to what you can find with a mail to Shenzhen...).
People need to give more attention to the trustworthiness of the actual resseller when buying to third party shops on Amazon, Ebay or AliExpress (they're more or less exactly the same to me). And to read a freaking datasheet. That's all.

lol your components are fake because they're Chinese.

Thank you for spending the time to share about such,
for the hobbyist certain components don't really matter as long as we can make our prototype projects before splashing out on better and certified components , so for the fake stuff well it has its purpose (cheap, small purchases, don't have to be a company)

But on a commercial side , well only a fool would buy from a uncontrolled source like Ebay and amazon and so.
And to say this is why companies that certify their parts/products charge more. you get better quality and safety.
Anyway im glad that there is a cheaper option, but i do tend to buy mainly from a proper component company.

We have to make a difference here between "fake" and "unbranded" components. If it's much cheaper than the "original", the reason might be that the unbranded one is just not good, or the original is much more expensive than it should be just because of the brand name.

I bought DS2431P+ fake in Mouser some weeks ago. I reported them. Surely big distributors also are suffering with it.

fet도 가짜가 있다니? 좋은 정보 감사

My employer had a Multi million machine go BOOM from this, took weeks to get going again, this was a replacement part from the original maker of the machine, so things got complicated legally

I’ve actually got a surprising number of real ones of AliExpress.

Yes, there are a lot of fake components. However, the part number is not exclusive to a manufacturer and does not make a product fake. The same part can be produced by several manufacturers and it will have the same functionality but small differences in performance. You need to check the datasheet. The thing that makes a component fake is being sold as manufactured by a certain brand but it is not.

Very interesting as I just bought some TIP31C's from an eBay supplier, fingers crossed!

If the fake component works like the real one, then it's not fake.

Where can we buy your T-Shirts?

it work but depend on test on tv crt east west and pwoer in lcd led tv

YES! IT IS BAD!

Do not support child labor, slavery/exploitation, and fraud by buying parts from sketchy dealers like eBay and Amazon. Not for any amount of savings!

Ive bought a bunch of parts off aliexpress, have no idea if they are genuine or not, but they were solid state relays that were dirt cheap compared to buying off RS or mouser, etc and I think only one manufacturer made this part in particular, either way, they are still working flawlessly.

That shirt! LOVE IT. :D
The diagram is gibberish but it looks SO COOL.

I would have been more than keen on buying the good genuine parts for my retro restoring projects. But in many cases Ebay is the only place to get old parts. Even if the genuine resller has it, It requres to buy 1000 units or the US shipping costs are 80USD for 2 mosfets 😢. Just right now strugling to get power transistors for old PC motherboards...

There are actually cheap real products out there now from china probably better to buy thise instead of maybe fake famous ones

Fake. Lol this was definitely an interesting perspective.

So, what is the parameter that fails the most and for sure?

A good way to suss fake components is just by checking the dimensions with a digital caliper against the datasheet. Very often the measurements are wildly out lol

This is so true ! Fake stuff everywhere. Recently I bought BMSs, Buck or Boost connectors etc. from Temu, AliExpress and eBay. Most of them don't work as advertised. Some have failed after few times of use. Pretty sure they use components failed and rejected from real production lines. I have lost faith in these websites. Perhaps we should stop buying from these sites altogether and buy only from reputed sites. Of course that means having to pay high prices and not to mention the ridiculous shipping costs.

Burned by this myself. Whole batch of 12F509 microcontrollers... I thought my 12 year old programmer had died because I suddenly started having issues programming new chips... literally bought a replacement programmer and found still could not program the chips. Hmmm.... Realized I had just gotten into a new batch of chips from eBay... ordered some from a reputable supplier instead of eBay and both old and new programmers had no issues... Grrrrrrr....... Yup, I really "saved" buying those cheap chips on eBay... NOT!

is there any fake brands to stay away from. im new to this and didnt know there were fake electronics till now. i buy my stuff on amazon. maybe this is why my 555 timer projects dont work

"Well known supplier"
I recognize that site as Digikey or Mouser.
I wonder if the manufacturer didn't just source a new supplier to cut costs?

thx for make this

I don't think fakes. we don't know what's going on with the manufacturers. this technology is not 100% perfect. When a manufacturer receives an order for 100 thousand pieces he must require the specifications published in the data sheet. he will start production. he will test each component. So out of 100 thousand there must be at least 15% which are outside the specifications. he will put them aside so 10 thousand pieces will be thrown away? these parts are functional..but slightly offset. crazy it works crazy it doesn't work.

Hola , aqui en Argentina llegan muchos componentes que son copias y no funcionan , Gracias por el video !!

Are the Bojack ICS bad then ? I've just bought some

relabelled old pulls of the right type arent really 'fakes' ,but as old/used, may fail after short life, some are also of almost right type but wrong grade, such as supposedly 20mhz z80s actually lower speed grade,

If it works to prove a new concept its OK. But for assured performance for heaven's sake buy an original.

I once bought an APDS-9960 Gesture Sensor which would not be recognised by the Arduino library when I was testing it. The Library identifies the chip by looking in an 'identifier' register (I2C) so, I read the register and it had a completely different value from the manufacturers datasheet. I did some hunting around online and found out that there were some fakes going around that had a different identifier code. This chip actually had a completely different ID to the fakes that were going around aswell. Checking the datasheet, I found a few 'default' values that should be set up in other registers within the chip on power-up and found they were all correct when I read them. All indications (other than the ID) sugested it was genuine. I modified the library to accept the ID code I'd read as being correct and the chip worked perfectly. The manufacturers datasheet stated that the Identifier code is ALWAYS the same value so it's surprising that the fake chip should essentially be identical in every way except for an identifier code, unless the code is set in the factory AFTER the QC testing in an attempt to prevent the resale of reject parts. I suspect this is the case and is indication of the manufacturers trying to get a throttle on this problem. After all, the whole Quality control process is essential to the company's quality reputation and reject parts slipping into the supply lines undermine the company's good reputation. It's pretty crazy out there!!

Sure glad that 5 cent pack of screws I bought aren't counterfeit...theyre missing a dimension, but who needs 3 anyhow? Elitist much? 😂

if there is an option, always buy the chinese brand rather than famous brand that has same price.

I wanted to be like you. Please let me know how i can.

I love electronics but any how don't know how to start.

Let's not call them fakes it's not easy to copy someone else's architecture and start manufacturing and make a ton of money without getting caught

These are most likely out of spec rejects from factory which are circulating in gray market

Clone ICs are more dangerous in my opinion you bang your head for hours just to realise you got a shittiest clone and it doesn't even support official library

There seem to be a class of components that work but are just cheaply made. I bought some through-hole resistors on aliexpress and the leads are needle-thin compared to the thick leads on my 1980s parts. The resistors measure fine and work fine since they don't get hot. Found some TO-220 parts with a very thin heat sink tab compared to the almost 1mm thick tab it should be. Still worked but the heat sinking just can't be as good.
