The real problem is you will have trouble finding them in most US
catalogs.

Use a 2N-xxxx equivalent, but you will find in most cases, the flat side
of the case needs to be turned 180 degrees. As Nigel said, most small
signal NPN transistors should work.

Just make sure of the collector/emitter orientation.
