Here is an image showing the pin diagram of this transistor.The 2SA913-Q transistor can have a current gain of 90 to 155. The gain of the 2SA913 will be in the range from 65 to 330, for the 2SA913-P it will be in the range from 65 to 110, for the 2SA913-R it will be in the range from 130 to 220, for the 2SA913-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SA913-Q might only be marked "A913-Q".The complementary NPN transistor to the 2SA913-Q is the 2SC1913-Q.The 2N5401S (SOT-23), DXT5401 (SOT-89), DZT5401 (SOT-223), KST5401 (SOT-23) and MMBT5401 (SOT-23) is the SMD version of the 2SA913-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA913-Q with the 2SA1006, 2SA1006A, 2SA1006B, 2SA1011, 2SA1306, 2SA1306A, 2SA1306B, 2SA1535, 2SA1535-Q, 2SA1535A, 2SA1535A-Q, 2SA1667, 2SA1668, 2SA1859, 2SA1859A, 2SA1964, 2SA913A, 2SA913A-Q, 2SA968, 2SA968A, 2SA968B, 2SA985A, 2SB1186A, 2SB546, 2SB546A, 2SB547, 2SB630, 2SB861, 2SB940, 2SB940A, FJP1943, FJP1943O, FJPF1943, FJPF1943O, KSB546, KTA1659, KTA1659A, KTA968, KTA968A, KTB1369, MJE15031, MJE15031G, MJE15033, MJE15033G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
