    Is there anything available to see if a particular transistor can be replaced with a different one .
    There are books galore on this but surely someone knows of a site that has them listed and searchable

    My query is a simple one
    I have no 2N5551 transistors on hand and I want to see if one in my box will do the job.

    You can compare data sheets.

    You can get one of the universal replacement part catalogs and see if your two candidates cross to the same universal replacement.

    2N5551 is a NPN 160 volt 600mA part. With out knowing what and ware your are using it, you should choose a similar part.

    NPN: Must be!
    160 volt: Maybe a 100 volt part will work. I don't know.
    600mA: There are many parts in the 500mA to 1A range.
    The physical size is TO-92. (little black "D" shaped) Might be important.
    2N5550, KSC2316, KSC2383 (I found these three)
    It is a high voltage part so it will be hard to find a replacement.

    April,

    I've provided information in a very old thread a few weeks ago about an online replacements database I found very useful. You can see my response here: http://www.electro-tech-online.com/threads/transistor-substitution-manual-chart-database.139703/

    I searched for 2N5551 in www.icreplacements.com and it provided me the following equivalents:

    BF391
    BF393
    BFP22
    MPSA42
    MPSA43
    SK3433

    You can check the complete information source here http://www.icreplacements.com/2/2N5...ubstitute-equivalent-part-cross-reference.htm or search for replacements for other integrated circuits, diodes, transistors, MOSFETs or other semiconductors in the previously mentioned Website.

    Hope it helps!

    Cheers,

    James

    I got an NTE194 from NTE Electronics ( www.nteinc.com) online substitution site.
