Here is an image showing the pin diagram of this transistor.The 2SA1305-Y transistor can have a current gain of 120 to 240. The gain of the 2SA1305 will be in the range from 70 to 240, for the 2SA1305-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1305-Y might only be marked "A1305-Y".The complementary NPN transistor to the 2SA1305-Y is the 2SC3297-Y.The 2SA1203 (SOT-89) and KTA1663 (SOT-89) is the SMD version of the 2SA1305-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1305-Y with the 2SA1012, 2SA1012Y, 2SA1262, 2SA1279, 2SA1279-Y, 2SA1288, 2SA1289, 2SA1290, 2SA1291, 2SA1307, 2SA1307-Y, 2SA1328, 2SA1328-Y, 2SA1451, 2SA1451-Y, 2SA1451A, 2SA1451A-Y, 2SA1469, 2SA1470, 2SA1471, 2SA1488, 2SA1742, 2SA1743, 2SA1744, 2SA1869, 2SA1869Y, 2SA1931, 2SA473, 2SA473Y, 2SA489, 2SA489-Y, 2SA490, 2SA490-Y, 2SA614, 2SA614Y, 2SA768, 2SA770, 2SB1019, 2SB1019-Y, 2SB1133, 2SB1134, 2SB1135, 2SB1136, 2SB1185, 2SB1187, 2SB1274, 2SB1375, 2SB1548, 2SB1548-P, 2SB1565, 2SB1566, 2SB434, 2SB434Y, 2SB435, 2SB435-Y, 2SB507, 2SB553, 2SB553-Y, 2SB761, 2SB761-P, 2SB762, 2SB762-P, 2SB824, 2SB825, 2SB826, 2SB834, 2SB857, 2SB858, 2SB903, 2SB919, 2SB941, 2SB941-P, 2SB942, 2SB942-P, 2SB947A, 2SB948A, 2SB953A, 2SB993, 2SB993-Y, BD202, BD204, BD242, BD242A, BD244, BD244A, BD302, BD304, BD534, BD536, BD540, BD540A, BD544, BD544A, BD546, BD546A, BD736, BD738, BD796, BD798, BD808, BD934, BD934F, BD936, BD936F, BD946, BD948, BD950, BDT82, BDT82F, D44C1, D44C2, D44C3, D44C4, D44C5, D44C6, D44C7, D44C8, D44C9, D45C1, D45C2, D45C3, D45C4, D45C5, D45C6, D45C7, D45C8, D45C9, D45H8, KSA473, KSA473Y, KSA614, KSA614Y, KSB1366, KTA1036, KTA1276, KTA1276Y, KTA1658, KTA1658Y or KTB988.
