Here is an image showing the pin diagram of this transistor.The 2SA1535A-Q transistor can have a current gain of 90 to 155. The gain of the 2SA1535A will be in the range from 90 to 220, for the 2SA1535A-R it will be in the range from 130 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SA1535A-Q might only be marked "A1535A-Q".The complementary NPN transistor to the 2SA1535A-Q is the 2SC3944A-Q.The KST93 (SOT-23) is the SMD version of the 2SA1535A-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1535A-Q with the 2SA1006, 2SA1006A, 2SA1006B, 2SA1009, 2SA1306A, 2SA1306B, 2SA1668, 2SA1859A, 2SA913A, 2SA913A-Q, 2SA968A, 2SA968B, 2SB630, 2SB940A, FJP1943, FJP1943O, FJPF1943, FJPF1943O, KTA1659A, KTA968A, KTB1369, MJE15033, MJE15033G, MJE5850, MJE5850G, MJE5851 or MJE5851G.
