There are certainly tons of fakes of these being made. Anyone know a good source for these?

2SA – 2SA PNP Power Transistor

That means the transistors were fabricated with JIS numbers issued just after the 2sa1387 was printed. AlanNov 11, You saw I did write I compare in 2sa183 with the one I bought from Digikey 3 years ago and they are identical except the lot number 5: This is from Bdent, not any 2a1837 stuffs. Mouser seems to carry the but not the arrgghh. They look OK but. This transistor is just got discontinued, it is cheap, I just don’t think there is incentive to make fake one for this cheap price.

No, create an account now. My Japanese Data manuals stop at 2SA! ChitsDec 2, Time for some upgrades in server hardware and software to enhance security and take AK to the next level.


They seems to be a big outfit. HyperionNov 9, I did measure the Vbe, it is in agreement with the ones I bought from Digikey 3 years ago. Especially now that the above mentioned replacements availability has fallen off the edge of a cliff.

Very shiny legs – to the point where Im a bit suspicious. And stops at 2SA From datasheet, hfe is minimum That’s normal, they build by the lots, you don’t expect the ones bought 3 year ago are from the same lot.

If you are interested, read my thread that I s2a1837 the Yours are on the high side. Bdent might have bough large quantity and still have old stock.

Thanks peeps – I think I need to stock up on these to potentially replace those Please contribute what you can to sales audiokarma. AlanDec 2, You 2sa183 try bdent – Here http: Stamped under all the “2SA’s” and 2SC is “5: Bdent seems to have plenty in stock and Im pretty sure I can trust that the parts will be genuine. Do you already have an account? I got these from Bdent.

Log in or Sign up. Good ole Ceitron in the US also has em in stock: That’s why I failed to see the need of getting them in pairs. You must log in or sign up to reply here.


Share This Page Tweet. I doubt anyone can fake it this good. I’ve come across dozens of fake TO transistors, and these are worthless! Illinois, close to St. The weird thing is that in my little component tester I am getting a pretty uniform hFe on the 2SC, but 2sa1387 much lower 9and also fairly consistent hFe on the 2SA’s.

People here order from them also. AlanNov 30, I choose this transistor for the low Vbe.

You can see in very detail the look of the lot 4: I bought it from Bdent also. Your name or email address: Unless anyone else knows of any other decent possible sub at the same specs?

I thought the hFe’s would be a bit closer Discussion in ‘ DIY ‘ started by slimecityNov 9, I measure the Vbe at about 10mA, Vbe is between 0. You are right to be looking carefully at the replacements for these 2aa1837, the mechanical and electronic chracteristics of the originals are difficult to match.
