My understanding is the 2222A is the military spec version. Maybe I'm
wrong, but it's got to be something like that, either that or a
slightly later version...... you might try googling a bit, spec
sheets for common parts can be pretty easy to find, I'm always
looking up the simple stuff myself. 73 de Alex NS6Y.

What's the difference between a PN2222 and a PN2222A transistor?
When used as a switch, can a PN2222 be used as a substitute for the
