The 2SA1450-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 2SA1450-S transistor can have a current gain of 140 to 280. The gain of the 2SA1450 will be in the range from 100 to 400, for the 2SA1450-R it will be in the range from 100 to 200, for the 2SA1450-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SA1450-S might only be marked "A1450-S".The complementary NPN transistor to the 2SA1450-S is the 2SC3708-S.The 2SA1368 (SOT-89) is the SMD version of the 2SA1450-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1450-S with the 2SA1275, 2SA1284, 2SA1319, 2SA1319-S, 2SA935, 2SA984K, 2SB560, 2SB647, KSA1013, KSA709C, KSP8599C or KTA1275.
