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