Here is an image showing the pin diagram of this transistor.The 2SA1535-R transistor can have a current gain of 130 to 220. The gain of the 2SA1535 will be in the range from 90 to 220, for the 2SA1535-Q it will be in the range from 90 to 155.Sometimes the "2S" prefix is not marked on the package - the 2SA1535-R might only be marked "A1535-R".The complementary NPN transistor to the 2SA1535-R is the 2SC3944-R.The 2N5401S (SOT-23), DXT5401 (SOT-89), DZT5401 (SOT-223), KST5401 (SOT-23) and MMBT5401 (SOT-23) is the SMD version of the 2SA1535-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1535-R with the 2SA1006, 2SA1006A, 2SA1006B, 2SA1306, 2SA1306-Y, 2SA1306A, 2SA1306A-Y, 2SA1306B, 2SA1306B-Y, 2SA1535A, 2SA1535A-R, 2SA1667, 2SA1668, 2SA1837, 2SA1859, 2SA1859A, 2SA1930, 2SA913, 2SA913-R, 2SA913A, 2SA913A-R, 2SA968, 2SA968A, 2SA968AY, 2SA968B, 2SA968BY, 2SA968Y, 2SA985A, 2SB546, 2SB546-Y, 2SB547, 2SB940, 2SB940-P, 2SB940A, 2SB940A-P, KSB546, KSB546-Y, KTA1659, KTA1659A, KTA1659AY, KTA1659Y, KTA968, KTA968A, KTA968AY, KTA968Y, KTB1369, KTB1369Y, MJE15031, MJE15031G, MJE15033, MJE15033G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
