2N2222A = 2N2222 (more or less?)

[Ginsly]

I'll be trying my hand at a Propolis soon, so I need some 2N2222's. I have some random black ones I thought were 2N2222, but they seem to be 2N2222A's.

The board itself seems to indicate that metal can transistors are ideal, but I keep on finding 2N2222A's like this: https://stompboxparts.com/2n2222a-npn-transistor-metal-can/

Going forward, are these essentially interchangeable? Within the "A" category is there a benefit to using the metal cans rather than the plastic ones I have? Metal can 2N2222's seem harder to come by. I've also read that 2N3906 is a decent sub for these...

Thanks, very curious!

2n222As have more Attitude

(They have a little more gain than 2n2222, but are probably interchangeable without much difference)

Just mind the pinout, there's at least 3 variations on the 2222.

@cdwillis & @Feral Feline - thanks much! Sounds like it won't make a huge difference in the Propolis...

I've seen 2N2222 in a few BOMs so far, but it seems that all I can really find are 2N2222A. Any advice on where to find them if I REALLY wanna stick to the schematic? Or are they so close that it's not worth the effort...

Small Bear has these, but I don't really need enough from SBE at the moment: https://smallbear-electronics.mybigcommerce.com/unbranded-2n2222-work-alike/

Amongst the "A-Team", Any real reason to get the metal can 2N2222As rather than just use the little black ones I already have?

Also a PN2222A and a 2PN2222A ... Probably the most confusing damned transistor I've encountered.

Reminds me of my WIP folders for projects.

Hahahaha I'm a printmaker and do a lot of Photoshop image prep - the amount of "oh no, DEFINITELY the MOST RECENT.psd" is absolutely out of control. Hilarious, man.

So... what would YOU use in the Propolis, @Robert ? 2N2222A close enough, or do I hunt for metal can 2N2222?

Calling a file final is the surefire kiss of death "do it again" in my experience. I had to stop calling the deliverables that a decade ago.

Mouser has them, but the original used TO-92.


This is an older schematic that wasn't actually my trace, so it very well could have been 2N2222A ...

I'll do some digging and see what I can find.

 

[Ginsly]

@Robert - thanks SO much, I really appreciate it!

That was awesome of you to post the Regular Fuzz BOM too. Very much looking forward to that one!

Any close-enough subs for the ZTX618 and ZTX649 in that one?

My recording folder looks like that. Drives my singer nuts when we're working on a track.

I can't believe they charge like 300 dollars for this freaking pedal

Fuzz pedals do seem to have the highest margin of all categories.. I get the Germanium mojo aspect, but it's amazing how brazen some companies are!

@Ginsly — If you socket the transistors you won't risk burning them up while soldering and then you can try both 2N2222 and 2N2222A then let us know if there's any mojo in the metal-cans...
