The 2SA733Q 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 2SA733Q transistor can have a current gain of 135 to 270. The gain of the 2SA733 will be in the range from 90 to 600, for the 2SA733K it will be in the range from 300 to 600, for the 2SA733P it will be in the range from 200 to 400, for the 2SA733R it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA733Q might only be marked "A733Q".The complementary NPN transistor to the 2SA733Q is the 2SC945Q.The 2SA812 (SOT-23), 2SA812-M5 (SOT-23), KSA812 (SOT-23) and KSA812-Y (SOT-23) is the SMD version of the 2SA733Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The H733-Q, HS733-Y is the TO-92 version of the 2SA733Q.You can replace the 2SA733Q with the 2SA1015, 2SA1032, 2SA1048, 2SA1175, 2SA1246, 2SA1266, 2SA1267, 2SA1283, 2SA1284, 2SA1317, 2SA1318, 2SA1391, 2SA1392, 2SA1450, 2SA1481, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534A, 2SA1619A, 2SA1680, 2SA1761, 2SA684, 2SA720, 2SA935, 2SA935-Q, 2SA953, 2SA953-L, 2SA954, 2SA954-L, 2SA984, 2SA984K, 2SA993, 2SB1116, 2SB1116-L, 2SB1116A, 2SB1116A-L, 2SB1229, 2SB560, 2SB647, 2SB740, 2SB764, 2SB892, 2SB985, A1015, A733, A733Q, BC212, BC212A, H733, H733-Q, KSA1015, KSA708C, KSA733C, KSB1116, KSB1116-Y, KSB1116A, KSB1116A-Y, KSB1116S, KSB1116S-Y, KSP2907AC, KSP8598C, KSP8599C, KTA1266, KTA1267 or KTB764.
