The 2SA733R 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 2SA733R transistor can have a current gain of 90 to 180. 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 2SA733Q it will be in the range from 135 to 270.Sometimes the "2S" prefix is not marked on the package - the 2SA733R might only be marked "A733R".The complementary NPN transistor to the 2SA733R is the 2SC945R.The 2SA812 (SOT-23), 2SA812-M4 (SOT-23), KSA812 (SOT-23) and KSA812-O (SOT-23) is the SMD version of the 2SA733R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The H733-R, HS733-O, KSA733O is the TO-92 version of the 2SA733R.You can replace the 2SA733R with the 2SA1015, 2SA1020, 2SA1048, 2SA1266, 2SA1267, 2SA1283, 2SA1283-D, 2SA1284, 2SA1284-D, 2SA1315, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1533, 2SA1534A, 2SA1619A, 2SA200, 2SA684, 2SA720, 2SA777, 2SA817, 2SA817A, 2SA935, 2SA935-P, 2SA953, 2SA953-M, 2SA954, 2SA954-M, 2SA984, 2SA984K, 2SA993, 2SB560, 2SB647, 2SB647A, 2SB764, A1015, A733, A733R, BC212, H733, H733-R, KSA1015, KSA708C, KSA733C, KSA931, KTA1266, KTA1267, KTA1274, KTA1281, KTA200, KTA708, KTB764 or PN3645.
