Those barstids at NXP have done it again. Stock up on BFT92s while you can.

Damn. All the fast discretes are going away, especially the PNPs.
I recently bought 12,000 of BFQ149.

There's still a few MMBTH parts in production. The nice NEC things are mostly gone.
Anybody know of remaining RF bipolars in SOT23 or SOT89?

I've got a reel of MMBTH10, more than a lifetime supply at my rate.
(Not very screaming, but a good jellybean substitute for 2N3904 and the like -- smaller and faster.)

MMBTH81 is a kinda-fast PNP.
-- John Larkin Highland Technology, Inc lunatic fringe electronics
I have about 60k JFETs, divided between BF862s and CPH3910s, because small, low noise JFETs are irreplaceable. There are usually circuit tricks that can be used instead of PNPs for the things that I mostly care about, so I'm not going to sink that amount of dough into BFT92s.
At this point the only fast PNPs are BFT92s and the Intersil HFA series arrays.

I am so glad I switched to designing ICs many, many years ago...

BTW, what is the difference between BFT93 and BFT92? I don't see anything significant in datasheets. Am I missing something?

It's an NPN though. There are lots of fast NPNs still, but it looks like the BFT92 and Intersil HFA parts are the only fast PNPs left in "full production", whatever that means. Get 'em while they last, folks.

The BFT93 seems to be a slightly larger version--35 mA I_Cmax vs. 25 mA for the BFT92, V_CEO = 15V vs. 20V. So it's approximately 1.5x as large as the BFT92. If they were going to bail on one and keep the other, I support their choice, but given that they already axed the BF862, I'm not optimistic. :(

So looks like nothing significant, I can relax :) I do have a reel of BFT92s so that will be enough for the rest of my life...

Huh, so if instead everyone switched to the BFT93 and there was still enough demand maybe it would live on...? You hoarder's are ruining everything. :^) (we have life time buys of several now gone parts.)
