    I am TRYYYYING to finish a BYOC chorus, and I've lost the 2N5087 transistor I usually order parts from Futurlec but I'd like to get this together before I retire. The only PNP that Pedal Parts Plus has is a 2N3906 would this be a good replacement?

    It depends on the application. The schematic might help us answer your question.

    Hi Rustom,
    Please elaborate what kind of application you are using it in; so that we can help you out.

    I sometimes use this site. http://english.electronica-pt.com/
    According to this site BC 214, BC 416, BC 560, 2SA872(A) and 2N508 may be replacements. You could at least download the datasheets and see how close they match

    Yes your 2N 3906 is a possible replacement usefully with the same pinout but,

    1) It has a lower the power rating so check if this is critical.

    2) Its voltage rating is 40 volts as opposed to 50. I can't see your circuit needing this but check anyway.

    3) It has a much higher frequency rating so you may need to add or increase feedback capacitance for stability.

    As others have said post the circuit for better advice.

    Contact me and I will send two pieces, no charge (T0-92)
    will take about 1 week to get to Manila
    can also preselect to verify that hFE >400
    first two pieces tested measured 512 and 500
    the 2N3906 may work, depending upon circuit requirements, but I consider it a poor replacement
