Here is an image showing the pin diagram of this transistor.The KSA1381-F transistor can have a current gain of 160 to 320. The gain of the KSA1381 will be in the range from 40 to 320, for the KSA1381-C it will be in the range from 40 to 80, 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.The complementary NPN transistor to the KSA1381-F is the KSC3503-F.The BF621 (SOT-89), BF821 (SOT-23) and PMBTA92 (SOT-23) is the SMD version of the KSA1381-F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSA1381-F with the 2SA1353, 2SA1353-F, 2SA1381, 2SA1381-F, 2SA1479, 2SA1479-F, 2SA1480 or 2SA1480-F.
