Here is an image showing the pin diagram of this transistor.The 2SC2706-R transistor can have a current gain of 55 to 110. The gain of the 2SC2706 will be in the range from 55 to 240, for the 2SC2706-O it will be in the range from 80 to 160, for the 2SC2706-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC2706-R might only be marked "C2706-R".The complementary PNP transistor to the 2SC2706-R is the 2SA1146-R.You can replace the 2SC2706-R with the 2SC2581, 2SC2837, 2SC3182, 2SC3182-O, 2SC3182-R, 2SC3263, 2SC3280, 2SC3280R, 2SC3281, 2SC3281R, 2SC3284, 2SC3519, 2SC3519A, 2SC3519A-O, 2SC3519A-P, 2SC3519A-Y, 2SC3855, 2SC3907, 2SC3907-R, 2SC4468, 2SC5198, 2SC5199, 2SC5200, 2SC5200N, 2SC5242, 2SC5358, 2SC5948, 2SC5948-R, 2SC5949, 2SC5949-R, 2SC6011, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, 2SC6145, 2SC6145A, 2SD1148, 2SD1148-R, 2SD2155, 2SD2155-R, FJA4310, FJA4313, FJL4315, KTC5200, KTC5200A, KTC5242, KTC5242A, MAG6333, MJW3281A, MJW3281AG or NTE2328.
