    What is the PNP equivalent of the NPN 2222 transistor? I just want a general purpose PNP transistor.

    I am accustomed to using the 2N2907 or 2N2907A as the complement to the 2N2222 or 2N2222A.

    That would be my choice also. The plastic package is PN2907.

    Ditto, the PN2222 is also the plastic version.

    Hi,

    If you are working on 2n2222, then you should have a look at Introduction to 2n2222. They have explained it in detail and have also shared its Proteus Simulation.

    Thanks.

    I like the 2n3904 and the 2n3906 but the 2N2907 works with the 2n2222
    but for most stuff the 2n3904 and 2n3906 match better

    It depends on the application as well, they have some differences in their operations so I would suggest you to read their datasheets first.

    People seem to get hung-up on replacing transistor with what they have been informed is a compatible replacement.

    Back in the day when hi-fi amplifiers used discrete components in their construction – I was often called upon to repair friends/acquaintances amplifiers that had ceased working.
    All I had in my selection of available transistors was six variants (low, medium and high power – one of each flavour, PNP & NPN).

    Consulting my copy of Towers Transistor Selector to ensure that the voltage (C-E) was adequate and the pin out arrangement was all I needed.

    Even today, I have plastic box with separate compartments to store transistors, each compartment is labelled with the transistor number, NPN/PNP, pin out, max C-E voltage, max collector current and power dissipation. So unless there is some special requirement, such as high gain or high frequency, for 99% of the circuits I build or repair this is all I need to know.

    This thread began in April 2009. I sincerely hope the original poster, who had a single post, has found a compliment to the 2N2222 by now. :) While I agree the 2N2907 is a close complimentary fit one should review the data sheets to make sure, in their application, the selected compliment will work, as others have mentioned. Now if we wait till April of 2019 we will have a 10 year old thread.

    Our new necroposter, xainnasir, has been a busy lad lately. :rolleyes:

    It would seem so. :)

    My guess is using signature line to pimp website.
