The 2SA1032 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 2SA1032 transistor can have a current gain of 100 to 320. The gain of the 2SA1032-B will be in the range from 100 to 200, for the 2SA1032-C it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SA1032 might only be marked "A1032".The complementary NPN transistor to the 2SA1032 is the 2SC2310.The 2SA812 (SOT-23) and KSA812 (SOT-23) is the SMD version of the 2SA1032 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1032 with the 2SA1015, 2SA1048, 2SA1246, 2SA1266, 2SA1267, 2SA1317, 2SA1318, 2SA1391, 2SA1392, 2SA1450, 2SA1481, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534A, 2SA1619A, 2SA684, 2SA720, 2SA733, 2SA935, 2SA953, 2SA954, 2SA984, 2SA984K, 2SA993, 2SB1229, 2SB560, 2SB647, 2SB740, 2SB764, 2SB892, 2SB985, A1015, A733, BC212, H733, KSA1015, KSA708C, KSA733C, KTA1266, KTA1267 or KTB764.
