The KSB564AC is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads. Suffix "C" means center collector in KSB564A.
Here is an image showing the pin diagram of this transistor.The KSB564AC transistor can have a current gain of 70 to 400. The gain of the KSB564ACG will be in the range from 200 to 400, for the KSB564ACO it will be in the range from 70 to 140, for the KSB564ACY it will be in the range from 120 to 240.The complementary NPN transistor to the KSB564AC is the KSD471AC.The 2SA1588 (SOT-323), KTA1505 (SOT-23) and KTA1505S (SOT-23) is the SMD version of the KSB564AC transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SB564A is the TO-92 version of the KSB564AC.You can replace the KSB564AC with the 2N4954, 2SB598 or KSB811.
