U updownleftright New Member Oct 20, 2009 #1 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. https://www.electronic-circuits-diagrams.com/alarmsimages/6.gif water level indicator with alarm circuit diagram Thank you guys!

E electronspeed New Member Oct 20, 2009 #3 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...
