A constant topic - transistor substitution. I needed a sub for a 2sc1222, and as the dates on the threads change, so do the answers. Some is due to obsolescence, of course, but it is changes due to the understanding of how the transistor is applied in the circuit that seem the most important - only I don't always know what that is.
The 1222 is in the muting circuit of a Kenwood KA-3500. Suggested substitutes have included these: KSC945C, KSC1845FTA, KSC2383YTA, KSC2690AYS, and ZTX694B. Pull them all up at Mouser to compare, and you get quite a range of numbers. Now the question - what numbers are the most important when choosing the best substitute? and, how do I tell?
Still learning! Thanks...
