Hello,
I'm in the first electrical engineering year and it's required to make an electronics project.
I've found a pdf that contains some projects and I've chosen this project pictured below.
The transistors T1 & T2 are BC547B
In the market I found BC547, is it equivalent to BC547B ?
and for the T3 (BEL187-P) I can't find it in the market, what is the alternative ?
