The 2SA564-Q 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 2SA564-Q transistor can have a current gain of 130 to 260. The gain of the 2SA564 will be in the range from 65 to 700, for the 2SA564-O it will be in the range from 65 to 130, for the 2SA564-P it will be in the range from 90 to 180, for the 2SA564-R it will be in the range from 180 to 360, for the 2SA564-S it will be in the range from 260 to 520, for the 2SA564-T it will be in the range from 360 to 700.Sometimes the "2S" prefix is not marked on the package - the 2SA564-Q might only be marked "A564-Q".You can replace the 2SA564-Q with the 2N3702, 2N4058, 2N4059, 2N4061, 2N4952, 2N4954, 2N5366, 2SA1015, 2SA1031, 2SA1032, 2SA1048, 2SA1150, 2SA1175, 2SA1246, 2SA1266, 2SA1267, 2SA1271, 2SA1273, 2SA1317, 2SA1318, 2SA1391, 2SA1392, 2SA1481, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534, 2SA1534A, 2SA1619, 2SA1619A, 2SA1680, 2SA1761, 2SA564A, 2SA564A-Q, 2SA608, 2SA628, 2SA683, 2SA684, 2SA719, 2SA720, 2SA733, 2SA928A, 2SA950, 2SA952, 2SA966, 2SA984, 2SA993, 2SB1229, 2SB564, 2SB598, 2SB621, 2SB621A, 2SB740, 2SB764, 2SB892, 2SB985, A1015, A733, BC212, BC212A, BC257, BC258, H733, KSA1015, KSA642C, KSA733C, KSA928A, KSB564AC, KSB810, KSB811, KTA1266, KTA1267, KTA1271, KTA1272, KTA1273, KTA1282, KTA1283, KTB764, MPS3638, MPS3638A, PN3638, PN3638A or STB1277.
