ASK to BBD

[czapa tranzystor 2]

Hi
I have occasions to buy SAD1024 without letter ,,A''
This chip i compatible with SAD1024A ?
Regards Łukasz

I can't find what the A suffix is for... it'll be some kind of package designation, probably something like extended temperature functioning range so I wouldn't worry about it not having it.

Be careful they're not fakes though, i'd never seen a fake SAD1024 before but when looking for this information I found this shot



Which looks very suspicious to me.

that looks blacktopped and reprinted

Which means... it could be any old chip, the photo is from one of those Asian wholesale sites so I would assume, unless they found hundreds of SAD's, that it's a fake and not just a reprint of an original (which I never quite understood the reason for doing).

That sure is a nice sanded PT2399. They could have at least reprinted "RETICON" in the correct font! Looks like they're getting downright lazy with the fakes.
