Identification and alternatives

Hello, Damian here very new into the world of electronics. I just run across this electronic part which I believe is a type of AC switch transistor. I was looking for it but can’t find the exact match and millions of similar things pops out.

I was also able to find the data sheet

And it is part of this pcb int the SCR slot

Please help and thanks in advance
