If not, then how is component quality assured? These are near-universal replacements for TO-3 package output devices in many vintage SS amps and receivers.

In my view, this response falls short of the need. The D and B are the most counterfeited transistor in history. I just want to try and buy the “best” transistors and I am trying to understand some of the differences in specs. I have these available from a previous project.

BinaryMikeAug 9, As far as ordering out-of-production Japanese transistors from unknown sources, only if you’re determined to learn a lesson the hard way, I might add that myself and others have already learned at dtaasheet financial cost and much labor rebuilding damaged boards. The post up top has some other numbers, but if I would have known to use the Motorola’s even when these B,D where around I would have used those Mj’s instead.

MCM is a reliable source, so they’re very unlikely to be counterfeits. If you really want those devices, buy new parts made by On-Semi from Mouser or Digikey.

Datasheeet for your guidance EW! Do you already have an account? It might be fun to get a pair and cut them open, if they aren’t too expensive. Well even better are the mj, or find the new number from “On” of those.

Yes, my password is: I assume you haven’t located a better option? Your name or email address: MayankJun 14, I was part of the team that assisted in the tweaking of the fabrication process. But of course Motorola had to sell the dang semi biz. FootFungusAug 4, Does MCM use a curve tracer and die inspection for replacement component quality assurance?


On-Semi was a spin-off from Motorola, when Moto divested the discrete semiconductor biz from the IC biz.

No, create an account now. MayankJun 15, I am not comfortable comparing the graphs on the datasheets and was hoping that 2xd424 of the Jedi Masters here can help.

Toshiba 2SB554/2SD424 equivalents

Toshiba hasn’t made these in years and years. One of the output transitors blew in the process. Yes, my password is: Gary, whose title is Technical Datashet, initially responded with the following comments: Do you already have an account? I created a major fireworks display when my test probe slipped and shorted on a nearby component while trying to adjust the bias: BinaryMikeAug 4, Oregon, land of magnificent stumps.

Heck, Motorola even made or resold? They’ve been out of production for many years, and any ‘new’ devices you may find are certainly Chinese remakes that are not to be trusted.

I didn’t mean it to sound that way. EchoWarsFeb 23,
