The guy in the video really knows his stuff......Stuff All....that is!
The component you are asking about is Not a SCR and it is Not a PnP transistor as he has implied to you, it is simply a NpN transistor and just about any NpN transistor will do the job.
BC-547, BC-548, BC-549, BC-337, PN-100, just to name a few common garden varieties.
Just use what ever you have in your junk box.
The 10 ohm resistor to ignite the match is a over kill, and a thin single strand of wire will do the same job, or my favorite when i made these things as a kid was to use steel wool fluffed out a little, if you add a little gunpowder around the steel wool it will erupt in flames fast.
