Here is an image showing the pin diagram of this transistor.The 2SC2681-R transistor can have a current gain of 60 to 120. The gain of the 2SC2681 will be in the range from 60 to 200, for the 2SC2681-Q it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC2681-R might only be marked "C2681-R".The complementary PNP transistor to the 2SC2681-R is the 2SA1141-R.You can replace the 2SC2681-R with the 2SC4388, 2SC4886, 2SC5101, 2SC5359, 2SD1716, 2SD1716-Q or FJAF4310.
