Here is an image showing the pin diagram of this transistor.The 2SC1030 transistor can have a current gain of 35 to 200. The gain of the 2SC1030-A will be in the range from 35 to 70, for the 2SC1030-B it will be in the range from 60 to 120, for the 2SC1030-C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC1030 might only be marked "C1030".You can replace the 2SC1030 with the 2SC1343, 2SC1584, 2SC2431, 2SC2433, 2SC519A, 2SC520A, BD315, BD317 or KD503.
