Here is an image showing the pin diagram of this transistor.The 2SC2563-Y transistor can have a current gain of 120 to 240. The gain of the 2SC2563 will be in the range from 55 to 240, for the 2SC2563-O it will be in the range from 80 to 160, for the 2SC2563-R it will be in the range from 55 to 110.Sometimes the "2S" prefix is not marked on the package - the 2SC2563-Y might only be marked "C2563-Y".The complementary PNP transistor to the 2SC2563-Y is the 2SA1093-Y.You can replace the 2SC2563-Y with the 2SC2579, 2SC2580, 2SC2581, 2SC2706, 2SC2706-Y, 2SC4278, 2SC4652 or 2SD1289.
