  1. The 2n can handle more current but the 107 is more sensitive.


  2. from my memory:

    you should download the data sheets and compare them

    Max current, the 2222 is higher

    HFE is speced at 2 ma for the 107, 150ma for the 2222

    in general, the 107 is designed for operation in the 1-10 ma region. The 2222 for the 10-200ma region, although both will operate out of those areas.

    I suspect the 107 has smaller capacitances than the 2222.
