    Hello,
    this looks like a japanese transistor (same case of the 2sd973 for
    example), marked as N1215 '95 ('95 could be a date code).
    Can anyone help me identifying it? Looks like open circuit.
    Thanks in advance

    Usually when written like this, there is an implied '2' in front, ie 2N1215.

    If 1995 unlikely Ge 2N1215
    Could it be a Russian Cyrillic "N" ?
    Definitely low power transistor casing ? eg < 1A

    definitely low power, looks like japanese, all other components in the
    car radio are japanese.
    Might be a RN1215 but I wasn't able to find a datasheet to confirm.

    Thanks

    If the case style is the flattish one with a chamfer face at the top , it
    was a popular style for Russian made transistors. Can there be a worn off
    character before the N ?

    the case is identical to the one in the following datasheet:

    http://www.ortodoxism.ro/datasheets/panasonic/2SD973.pdf

    And no, no possible other characters, the case is clean, the marking
    very sharp and the code begins right on the edge of the case. There's
    a dot under the N, not sure if it helps.
    I can also send a picture if it helps.
    Regards

    put the pic on some site and place the URL here

    RN1215 should be eline case, but with internal base R would explain apparent
    o/c on diode test

    via Google, apparently, in Sanskrit

    "if there's a dot under the N, then that's pronounced like a regular N but
    with a little bit of an R at the beginning"

    curioser and curioser.
    Exceedingly subtle, if a variant of drop the L from LA... , LB, LC ICs and
    the mu from uPD... NEC, 2S from 2SA..... etc

    I have the pic and can send to anyone, just contact me via email. I
    wouldn't know where tu put it anyway. Looks like it's likely an
    RN1215 but without a datasheet it's kind of difficult to guess the
    resistor value just for example.

    Thanks

    How about a UN1215? It has an internal 10K base resistor.

    Thats presumably the one.
    Now does Panasonic/Matsushita use the dot code for other dropped letters on
    SMD/small items, say MN.... ?

    The free one I use a lot of is
    http://www.graffiti.net/

    you can put odd pics on there without having thenm associated with a text
    file and others can view such isolated pics, not the case with all such
    hosting sites (remote linking).

    It would be useful, if indeed Panasonic, for the font style of the
    lettering, relative dot position etc
