Almost any transistor will do that can pass the load current.

BFX84 60V 1A
BFY51 60V? 1A
2N2222 30V 0.8A
ZTX653 100V 2A

The SL100 and SL100B are not listed in my book. Why are circuits listed using rare components?

According to the data, the NTE108 is a delicate very high frequency transistor which will pass only a low current, not what is wanted here.

NTE108 15V 50mA

Edit
The SL100 is 50V 0.5A, nothing like the NTE108

There are many FETs which could also be used.

Goes to show you can't trust seller's websites...

Well, I'm just trying to find some simple alarm circuits and these are the ones i found, if you have any simple circuits like this please send them to me, and thanks for the information about the SL100 and SL100b :)
