On-semi are discontinuing all of their TO-92 products because of a disagreement with a subcontractor. List includes all the MPSWs....

Holy fuck on a stick! That is a pretty broad swath of product!

[Laowei]

That's an original way to boost the Black Friday sales stats......

[spritzer]

For fucks sake....   Ohh well, back to finding replacements. 

[insanity]

Ah fuck. What should be do? Buy some stock or is there a high probability of finding an adequate replacement?

[kevin gilmore]

fuck me.

but what else is new

i think there are fairchild equivalents, but maybe not same pinout.

[Dusty Chalk]

Bap shoo be do...

Don't mind me, I see humour in everything.

[kevin gilmore]

well I just bought a lifetime supply of the mpsw06 and mpsw56

just to make sure. And at 1000 pieces, dirt cheap.

 

TT electronics is probably the best bet, have to get a quote from mouser

so group buy kind of thing.

 

going to search available Japanese companies now.

 

looking for 80v npn and pnp, 1 watt

[nopants]

Is mouser out of parts already? I need to make an order too

[kevin gilmore]

I would hurry.  last order date dec 31

last delivery date in may

 

but the following parts are identical silicon in surface mount

pzta06,pzta56  so will have to make adapters because they

require 6cm2 of heatsink copper

[gepardcv]

I just ordered 200 of each. Should be plenty for me, and I'm willing to share.

[mypasswordis]

Checking this place is not good for my wallet. I ordered some as well; thanks for letting us know, UFN. Currently Mouser still has enough to go around.

Stocks dwindling, got 50 each myself.

 

Me

[nopants]

I think I have a former stock of 100 pieces I guess I can make do

[kevin gilmore]

mpsa06/mpsa56 can be substituted everywhere except the outputs on the kgdynalobal

(have to check power levels on dynahi)

[GrindingThud]

Just ordered for my second SuSy Dynalo set.... Looks like this affects the KSA5 clone also.

[spritzer]

I bought 1000 of each type because... well I'm nuts.  I've spent way too much on transistors this month though.... 

[PretentiousFood]

Any reason to stock up if you're not building a Dynalo? Looks like the BC550/560 pair could be a drop in replacement unless you need the extra dissipation.

[spritzer]

KGSSHV/KGST/KGSSHV Carbon etc. all use these. 

[UFN]

Many of the things that On-semi are now dropping seem to have equivalents (or near-enough equivalents) from Fairchild and others, except if you need/want the MPSW 1W package.

 

That said, I'd never thought I see the day where I considered stockpiling BC547Bs just to be safe...

How is the KGSSHV Carbon coming? Any impressions on a prototype?

[spritzer]

I all but abandoned the project when the difference between new and old 009's came to light but I did just order PCB's for it.  Who knows when I'll build them though...

[insanity]

Nice to hear. Although the IMHO the KGST is really magical with the old 009. It leaves almost nothing to wish for. 

[nopants]

maybe it's time to fire up the circolotron nudge nudge
