Here is an image showing the pin diagram of this transistor.The 2SC5949-R transistor can have a current gain of 55 to 110. The gain of the 2SC5949 will be in the range from 55 to 160, for the 2SC5949-O it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SC5949-R might only be marked "C5949-R".The complementary PNP transistor to the 2SC5949-R is the 2SA2121-R.You can replace the 2SC5949-R with the 2SC3263, 2SC3281, 2SC3281R, 2SC3320, 2SC5200, 2SC5200N, 2SC5242, 2SC5358, 2SC6011, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, 2SC6145, 2SC6145A, 2SD1313, FJA4313, FJL4315, KTC5200, KTC5200A, KTC5242, KTC5242A, MAG6333, MJW3281A, MJW3281AG or NTE2328.
