2SA Datasheet, , Transistor Substitution Pair Monolithic Manual Japanese Hfe1 Data Book

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. I thought to look for a replacement, just in case and came up empty everywhere I dafasheet.

Question one is does anyone know of a replacement for this transistor? By placing two transistors together and melding their emitters, would this be a possibility for a replacement should none exist.

KingBubbaFeb ddatasheet, I find it hard to trust a product listing with no description, data sheet or even a datazheet picture. Thanks Avionic, but have you used or ever ordered one of these from them?


It won’t be a good idea to use two separate transistors in this case. It shouldn’t be that difficult to find these or dtasheet equivalentor even pulled parts enexpensively, just pay attention to the last letter if the manual has specifications for that.

Thanks to all for your responses and PMs. I see now that they are available, if in a somewhat limited fashion. I have learned of some suppliers that I have never heard of before and that is a good thing.

At this time, I do not need the item in question but was rather testing the waters in case I do.

This has been an excellent thread for me. Other comments and suggestions are, of datasyeet, still welcomed. KingBubbaFeb 14, Quite possibly they were the real thing. NTE43 replaces the 2sa AngelRaJul 27, YES but NTE parts for most of us in doing reputable repairs and restorations are an absolute begruggingly last resort.

OverLoadJul 27, I realize this is an old post from way back when but I find myself in need of a couple of these 2SA transistors. The NTE43 appears to be no longer available as a replacement plus comments on this datxsheet tell me to steer clear of NTE. Any comments on taking this route?


If this is a viable solution can someone supply the part number of the transistor needed to make a twin setup? Use a pair of matched KSA You can heatshrink the tops together to for thermal contact if you want to be thorough. FootFungusJan 11, Halisson and Rodrigan like this.

San Francisco Bay Area. ChrisMarantzJan 11, I have stocked up on a couple just in case. Resurrecting an old thread again It seems it’s not easy to find this part in Do you know any newer replacement?

It’s a quality amp I’m restoring, a SAE You must log in or sign up to reply here. Share This Page Tweet.
