Here is an image showing the pin diagram of this transistor.The 2SC2564 transistor can have a current gain of 55 to 240. The gain of the 2SC2564-O will be in the range from 80 to 160, for the 2SC2564-R it will be in the range from 55 to 110, for the 2SC2564-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC2564 might only be marked "C2564".The complementary PNP transistor to the 2SC2564 is the 2SA1094.You can replace the 2SC2564 with the 2SC2565.
