Here is an image showing the pin diagram of this transistor.The 2SC1080 transistor can have a current gain of 40 to 140. The gain of the 2SC1080-R will be in the range from 40 to 80, for the 2SC1080-Y it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC1080 might only be marked "C1080".The complementary PNP transistor to the 2SC1080 is the 2SA680.You can replace the 2SC1080 with the 2SC1079, 2SC1584, 2SC2428, 2SC2431, 2SC2433, 2SD424, 2SD425, 2SD426, 2SD733, 2SD733K, 2SD753, BD317, MJ15001, MJ15001G, MJ15003 or MJ15003G.
