Here is an image showing the pin diagram of this transistor.The 2SC510-O transistor can have a current gain of 50 to 150. The gain of the 2SC510 will be in the range from 30 to 150, for the 2SC510-R it will be in the range from 30 to 90.Sometimes the "2S" prefix is not marked on the package - the 2SC510-O might only be marked "C510-O".The complementary PNP transistor to the 2SC510-O is the 2SA510-O.You can replace the 2SC510-O with the 2N5320.
