Here is an image showing the pin diagram of this transistor.The 2SC5949-O transistor can have a current gain of 80 to 160. The gain of the 2SC5949 will be in the range from 55 to 160, for the 2SC5949-R it will be in the range from 55 to 110.Sometimes the "2S" prefix is not marked on the package - the 2SC5949-O might only be marked "C5949-O".The complementary PNP transistor to the 2SC5949-O is the 2SA2121-O.You can replace the 2SC5949-O with the 2SC3281, 2SC3281O, 2SC3320, 2SC5200, 2SC5200N, 2SC5200O, 2SC5242, 2SC5242O, 2SC5358, 2SC5358-O, 2SC6011, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, 2SD1313, FJA4313, FJA4313O, FJL4315, FJL4315O, KTC5200, KTC5200A, KTC5200AO, KTC5200O, KTC5242, KTC5242A, KTC5242AO, KTC5242O, MJL4281A, MJL4281AG, MJW3281A, MJW3281AG, NTE2328 or TTC5200.
