The 2SA564A-S 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.
Here is an image showing the pin diagram of this transistor.The 2SA564A-S transistor can have a current gain of 260 to 520. The gain of the 2SA564A will be in the range from 65 to 700, for the 2SA564A-O it will be in the range from 65 to 130, for the 2SA564A-P it will be in the range from 90 to 180, for the 2SA564A-Q it will be in the range from 130 to 260, for the 2SA564A-R it will be in the range from 180 to 360, for the 2SA564A-T it will be in the range from 360 to 700.Sometimes the "2S" prefix is not marked on the package - the 2SA564A-S might only be marked "A564A-S".The KST5086 (SOT-23), KST5087 (SOT-23), MMBT5086 (SOT-23) and MMBT5087 (SOT-23) is the SMD version of the 2SA564A-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA564A-S with the 2SA1025, 2SA1081, 2SA1083, 2SA1084, 2SA1127, 2SA1127-S, 2SA1174, 2SA1175, 2SA1246, 2SA1316, 2SA1317, 2SA1318, 2SA1391, 2SA1392, 2SA1481, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA608N, 2SA733, 2SA872, 2SA893, 2SA893A, 2SA929, 2SA990, 2SA991, 2SB1116, 2SB1229, 2SB560, 2SB726, 2SB726-S, 2SB892, 2SB985, A733, BC257, H733, KSA733C, KSB1116, KSB1116S or NTE193A.
