Here is an image showing the pin diagram of this transistor.The 2SA1535 transistor can have a current gain of 90 to 220. The gain of the 2SA1535-Q will be in the range from 90 to 155, for the 2SA1535-R it will be in the range from 130 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SA1535 might only be marked "A1535".The complementary NPN transistor to the 2SA1535 is the 2SC3944.The 2N5401S (SOT-23), DXT5401 (SOT-89), DZT5401 (SOT-223), KST5401 (SOT-23) and MMBT5401 (SOT-23) is the SMD version of the 2SA1535 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1535 with the 2SA1006, 2SA1006A, 2SA1006B, 2SA1306, 2SA1306A, 2SA1306B, 2SA1535A, 2SA1667, 2SA1668, 2SA1859, 2SA1859A, 2SA913, 2SA913A, 2SA968, 2SA968A, 2SA968B, 2SA985A, 2SB546, 2SB547, 2SB940, 2SB940A, KSB546, KTA1659, KTA1659A, KTA968, KTA968A, KTB1369, MJE15031, MJE15031G, MJE15033, MJE15033G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
