Here is an image showing the pin diagram of this transistor.The 2SC5101-P transistor can have a current gain of 70 to 140. The gain of the 2SC5101 will be in the range from 50 to 180, for the 2SC5101-O it will be in the range from 50 to 100, for the 2SC5101-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC5101-P might only be marked "C5101-P".You can replace the 2SC5101-P with the 2SC4388, 2SC4388-P, 2SC4886, 2SC4886-P, 2SC5359, 2SD1716, FJAF4310 or FJAF4310O.
