Here is an image showing the pin diagram of this transistor.The 2SA1248-T transistor can have a current gain of 200 to 400. The gain of the 2SA1248 will be in the range from 100 to 400, for the 2SA1248-R it will be in the range from 100 to 200, for the 2SA1248-S it will be in the range from 140 to 280.Sometimes the "2S" prefix is not marked on the package - the 2SA1248-T might only be marked "A1248-T".The complementary NPN transistor to the 2SA1248-T is the 2SC3116-T.The KST93 (SOT-23) is the SMD version of the 2SA1248-T transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1248-T with the 2SA1249, 2SA1249-T, 2SA1507 or 2SA1507-T.
