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 !

I think you mean 2N2222...
From memory the 2N2222 (TO18) has Vceo=30V and the A version has Vceo=40V. Therefore, you can use the A version in place of the 2222 but not necessarily the other way round. If Vce supply voltage is less than 30V then either will do.
