    Generally speaking, and I say generally, the higher collector current TO-92 devices had the center collector for better heat/power dissipation purposes. Much like the TO-220 have center collector and tab connection for that same reason.

    Screw it
    In MY book, they should not carry the same basic part number if they are not the same.

    The Bu is bulk
    The CT would be tape
    And CTA Cut Tape

    But they carry the same basic part number so the suffix should be the order delivery method. They should not rely on "small print" on the data sheet and not actually show the different pin out.
    I had the nations problems figured out one night while on blah blah blah........ huh?

    Agree Perry
    They should have a different JEDEC part number for that device.

    And, if you click here (https://www.mouser.com/Semiconductor...2N6517&FS=True)

    These ALL show the same data sheet. If you don't see the fine print, they all show the same pin out. That's some Hokey shit.


    I guess in the end, I'm a big dummy... no HUH on that one.....

    I ran into this some time ago. The transistors sat around for several months until I needed them. At that point it was too late to return them. I tossed them in the trash.

    Use the MPSA42 or ZTX857STZ and you will not run into this problem again. There is no alternate pinout for these devices thus no confusion.

    The ZTX857 is a much more robust device to boot.

    The MPSA 42 is pretty damn handy...
