Here is an image showing the pin diagram of this transistor.The KSA1381-C transistor can have a current gain of 40 to 80. The gain of the KSA1381 will be in the range from 40 to 320, for the KSA1381-D it will be in the range from 60 to 120, for the KSA1381-E it will be in the range from 100 to 200, for the KSA1381-F it will be in the range from 160 to 320.The complementary NPN transistor to the KSA1381-C is the KSC3503-C.The 2SA1721 (SOT-23), 2SA1721-R (SOT-23) and PMBTA92 (SOT-23) is the SMD version of the KSA1381-C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSA1381-C with the 2SA1156, 2SA1156M, 2SA1353, 2SA1353-C, 2SA1381, 2SA1381-C, 2SA1479, 2SA1479-C, 2SA1480, 2SA1480-C, KSA1156, KSA1156R, KSE350, MJE350 or MJE350G.
