are these NPN BJTs:

the same as those 2N2222 that has been around for since forever? can i trust that the reverse active and avalanche breakdown profiles are the same??

A transistor is slowly damaged when operating with avalanche breakdown of a reverse-biased emitter-base junction.
The 2N2222 and BT2222 are guaranteed to withstand a reverse emitter-base voltage of 6V or less.

Both transistors probably have the same chip but since the BT2222 is in a tiny case then it will overheat even with a very low power dissipation.
