I have a small circuit which controls the speed of a DC motor as per the ambient temperature. The circuit is working perfectly fine. I have across this circuit across a lot of forums and was just wondering if I could replace BC547 (Q1 in the circuit) with the commonly used 2N2222 npn transistor.
I checked out the SPICE simulation of the circuit and power dissipation isn't an issue (which usually is under most circumstances for NOT using 2N2222). Any other reasons that you could suggest.
Here is the circuit diagram - http://www.redcircuits.com/Page109.htm
Thanks in advance
