    My vrt databook lists the specs as ...

    2SC1307 HF-L, 70V, 8A(ss), PQ = 15W (50MHz)

    ss = peak value

    2SC2098 AM-L, 70V, 6A, PQ = 15W (28MHz)
    MRF475 AM/SSB-L 48V, 4A, PEP = 12W (30MHz)
    2SC1969 AM-L, 60V, 6A, PQ = 16W (27MHz)
    2SC2166 HF-L, 75V, 4A), PQ > 6W (27MHz)

    All of your replacement options appear to be inferior (I couldn't find
    the ERF2030).

    I found this transistor:

    2SC2050 AM-L, 60V, 6A, PQ > 13W (50MHz)

    FWIW, the 2SC1307 is listed as its sub, but not vice versa.

    BTW I can get a 2SC1307 for AU$10.45 in Australia, assuming it is not
    a fake.

    Hi, I am in need of a suitable replacement for a 2SC1307 rf transistor
    and was wondering if anyone had any suggestions. The 2SC2098 looks
    like a possibility as does the MRF475 both of which are about as old
    as the 1307 and equally if not more difficult (and expensive) to

    Or would I be further ahead trying an ERF2030 and associated
    components as some use to replace the 2SC1969 and 2SC2166.
