Here is an image showing the pin diagram of this transistor.The 2SA1248-R transistor can have a current gain of 100 to 200. The gain of the 2SA1248 will be in the range from 100 to 400, for the 2SA1248-S it will be in the range from 140 to 280, for the 2SA1248-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SA1248-R might only be marked "A1248-R".The complementary NPN transistor to the 2SA1248-R is the 2SC3116-R.The KST93 (SOT-23) is the SMD version of the 2SA1248-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1248-R with the 2SA1220A, 2SA1220A-Q, 2SA1249, 2SA1249-R, 2SA1507, 2SA1507-R, 2SA795A, 2SB649A, 2SB649A-C, KSA1220A, KSA1220A-O or KTA1700.
