are there a difference between the two?

2n222
2n222a

can they be interchanged?

please send me a direct e mail,

thanks for reading!!

No ! Come back here to read the replies. Are you too lazy to do that ?

Usenet doesn't exist for your personal convenience.

You mean 2N2222 don't you ?

Why not read a data sheet ?

And why do you want to use such an ancient inferior device ?

And don't post to non-existent groups either !

Are you sure they don't have another "2" (2N2222) in the part number?
2N222 was a germanium audio transistor from the '60s.

Transistor 2N2222
Higher voltage capacity for the A version.

You can allways change to A version.

Depends whose datasheet you read, but often the 2N2222 is a plastic TO-92
600mA device and the -A suffix a TO-18 canned 800mA device.

No, there's no such thing as a "2N2222" (or 2N2222A) in a plastic case.
The part number, "2N2222", is JEDEC registered, and the spec is very
specific.

You might very well be thinking of the "PN2222[A]" or "MPS2222[A]"

Cheers!

Thank you for posting that. You saved me the trouble. You're spot on of course.

This is indeed the "case". Hahaha I made a funny.
