Need help from Experienced Eyes: Toshiba 2SC2238/2SA968 Parts — Do these look genuine?
Oct 8, at I think doubt is always going to be a problem with obsolete parts, regardless of the number of counterfeits out there.
I wonder how long it will be before we start seeing fake Lovoltech LUD. My over-whelming instinct is to just use a current production part and be done with it.
Post 12 of Oct 7, at 9: Do you already have an account? I was going to say that I haven’t seen green in these particular transistor sets, so I’d vote for the bottom grouping as being genuine. Post 9 of Post 2 of I checked them and the gain of the straight T version were abyssmal. Post 8 of The ones from other parts of asia have the straight T as in your examples.
The Japanese are in short supply as well and buy them where they can 2sc22238 them.

Oct 9, at 4: Oct 8, at 5: To be honest, the fakes are more obvious than that. The moral here is that genuine Toshibas or not – where they are manufactured makes a difference. No, seeing those backs in your new photo leads me to belive that you have genuine Toshiba’s. The others with the straight T are asian junk The Toshibas from Japan have a block type vatasheet T.

Oct 5, at I’ve also never seen the 2SC with the straight “T”, but they are known to be genuine that way with the 2SA’s. Anyway, that’s about the extent of my experience with them. Bag and tag from Japan doesn’t mean much – I’ve had Korean and Indian in those bags. I still think the green ones are probably a reduced HFE output version, though.

It helps to see the backs, too. Post 6 of Yes, my password is: Post 1 of Post 15 of I have two sets I recently obtained, the first, from RF Parts with no source identification are seen below: Oct 9, at 9: Oct 7, at 8: Any ideas if these might be the real deal or just another set dataxheet counterfeit parts?
