The 2SA1319-R 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 2SA1319-R transistor can have a current gain of 100 to 200. The gain of the 2SA1319 will be in the range from 100 to 400, for the 2SA1319-S it will be in the range from 140 to 280, for the 2SA1319-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SA1319-R might only be marked "A1319-R".The complementary NPN transistor to the 2SA1319-R is the 2SC3332-R.The KST93 (SOT-23) is the SMD version of the 2SA1319-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1319-R with the 2SA1013, 2SA1013O, 2SA1275, 2SA1275-O, KSA1013, KSA1013O, KTA1275 or KTA1275O.
