2n5089 Alternative PCB082?

[masonlewisdiesel]

I'm out of 2n5089'a for the squidward. What characterisics am I looking for in a possible substitue? I have some S series(ex: s8550), A series(ex: a1015), as well as alot of BC 109,108(a,b,c), 2n2222(metal can), and bc183s. Maybe I should be patient and wait for the order of the 89s?
Thanks

BC108Cs might do the trick. 2n5089's tend to range in gain from 450-1.2k. bc108c will range from 420-800.

Specs are fairly similar. I'd go with those, just mind the pinouts.

Use sockets and try.

I built one a long time ago using 2n5088s.

You can use BC549 too.

(neither of those are on your list--you can probably use whatever though assume you socket it)

Thanks Stick, look man you gotta baby sit me all over this forum! Appreciate it big time!

Ya know that old foo fighters song, I'll stick around?

Yeah, it's about me.

You oughta stick around too.

Yeah, kinda the direction i was heading. Just got a Atlas component tester, I'm still trying to understand what is or is not significant regarding trannys, It cant be as simple as looking for the same pattern of polarity+gain+leakage to find a candidate...is it?

Any Si NPN with HFE over 200 or so will work fine. BC549C is your least expensive option. You could probably get away with 2N3904 or 2N2222A in that circuit. when subbing transistors, mind the pinout. BCxxx transistors have E & C swapped compared to the others.

Haha hell ya man!

FWIW, here's a quick little substitution guide . . . .

 

[Chuck D. Bones]

those J201 subs are dead wrong. Look at Vp & Idss in the datasheets. Gm (gain) can also vary significantly from one part # to the next.

Germanium substitution is hit & miss. You need to know what the circuit requires.

Thanks, I totally screwed the pooch with the BC183L's... got the two legs backwards.
