Here is an image showing the pin diagram of this transistor.The 2SC5100-Y transistor can have a current gain of 90 to 180. The gain of the 2SC5100 will be in the range from 50 to 180, for the 2SC5100-O it will be in the range from 50 to 100, for the 2SC5100-P it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC5100-Y might only be marked "C5100-Y".The complementary PNP transistor to the 2SC5100-Y is the 2SA1908-Y.You can replace the 2SC5100-Y with the 2SC4388, 2SC4388-Y, 2SC4886, 2SC4886-Y, 2SC5101, 2SC5101-Y, 2SD1488, 2SD1715, 2SD1716, FJAF4310 or FJAF4310Y.
