Fake parts evidence video - must watch

[Terry2000]

Excellent video tests fake versus genuine.

Fake pieces are terrible. From clothes, electronic parts and web pages. All is fake nowadays.

One thing i can say that most of the time fake components are distinguishable by good observation(physically).

Are these op amps genuine or not ?.

Yeah, but you have to buy them first, so time and money is allready lost on a useless part

TME is pretty reliable.
On top of that, the TI logo looks genuine, you usually don't have that on fake components (you'd rather have a "something", a spot that only remotely reminds of a TI logo...)
So I think the parts are OK.

(Edit: in the above video, you can already tell the fake whithout doing extensive tests - the IR logo is just wrong, so it can't be a genuine component after all, no need to test it, other than for YT views)

Then purchase from reputable source like i do (mouser, digikey etc). My point was for differentiation between fake & genuine opamps by observing electrically or physically.

Genuine TI part but not guaranteed low noise grade (5532A).

Genuine TI part but not guaranteed low noise grade (5532A).

Maybe that's why it's not marked "PA"? (On the other hand, unless they really screwed up production, the standard part probably meets the "A" spec as well - there is just no guarantee for it.)

 

[NanoFarad]

You can say that but it's not selected for low noise ('AP') by the manufacturer so why bother for measurements which requires $$$ equipments, where the price difference between the two is negligible!
