Is There a Replacement?

【2SA798 MITSUBIS】Electronic Components In Stock Suppliers in 2018【Price】【Datasheet PDF】USA

Question one is does anyone know of a replacement for this transistor? I realize this is an old post from way back when but I find myself in need of a couple of these 2SA transistors. If this is a viable solution can someone supply the part number of the transistor needed to make a twin setup?

It shouldn’t be that difficult to find these or 2SA equivalentor even pulled parts enexpensively, just pay attention to the last letter if the manual has specifications for that. Other comments and suggestions are, of course, still welcomed.

I have removed it and replaced it on the boards a total of four times now and it is getting a little beat looking, to the point that I fear to have to test it or remove it again.


At this time, I do not need the item in question but was rather testing the waters in case I do. It’s a quality amp I’m restoring, a SAE Do you already have an account? I have learned of some suppliers that I have never heard of before and that is a good thing. Resurrecting an old thread again Quite possibly they were the real thing.

No, create an account now. It won’t be a good idea to use two separate transistors in this case. OverLoadJul 27, Thanks to all for your responses and PMs. KingBubbaFeb 13, I find it hard to trust a product listing with no description, data sheet or even a lousy picture.

It seems it’s not easy to find this part in I thought to look for a replacement, just in case and came up empty everywhere I looked. NTE43 replaces the 2sa Thanks Avionic, but have you used or ever ordered one of these from them? You can heatshrink the tops together to for thermal contact if you want to be thorough. Halisson and Rodrigan like this. Do you know any newer replacement?


Use a pair of matched KSA Darasheet has been an excellent thread for me. I see now that they are available, if in a somewhat limited fashion.

The NTE43 appears to be no longer available as a replacement plus comments on this forum tell me to steer clear of NTE. Yes, my password is: AngelRaJul 27, By placing two transistors together and melding their emitters, would this be a possibility for a replacement should none exist.

YES but NTE parts for most of us in doing reputable repairs and restorations are an absolute begruggingly last resort.
