Here is an image showing the pin diagram of this transistor.The 2SC3281R transistor can have a current gain of 55 to 110. The gain of the 2SC3281 will be in the range from 55 to 160, for the 2SC3281O it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SC3281R might only be marked "C3281R".The complementary PNP transistor to the 2SC3281R is the 2SA1302R.You can replace the 2SC3281R with the 2SC3263, 2SC3320, 2SC5200, 2SC5200N, 2SC5242, 2SC5358, 2SC5949, 2SC5949-R, 2SC6011, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, 2SC6145, 2SC6145A, 2SD1313, FJA4313, FJL4315, KTC5200, KTC5200A, KTC5242, KTC5242A, MAG6333, MJW3281A, MJW3281AG or NTE2328.
