Substitute to BC148 Transistor

[updownleftright]

Hi guys!

I am kinda new to this circuit making stuff, and I took a introductory subject to Electrical Engineering. We needed to create a circuit project.

Problem is, I cant find a BC148 transistor and Im looking for a substitute. Can you guys help me find out the transistors that can replace BC148?

By the way, here's my circuit project.

Thank you guys!

It's just a plastic version of a BC108, a standard NPN small signal transistor - pretty well any general purpose one will do.

It also depends on how much specific this transistor is to your circuit requirement.BC148 is used for small signal general purpose amplification.There are a lot with same configuration .You may go for 2n222,bc107 etc...

Correction (not 2N222):
2N2222.
I would use a BC547, BC548, 2N3904 or 2N4401 transistor instead.

Thanks for the replies! I will definitely try looking for those transistors
