Here is an image showing the pin diagram of this transistor.The 2SA1305 transistor can have a current gain of 70 to 240. The gain of the 2SA1305-O will be in the range from 70 to 140, for the 2SA1305-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1305 might only be marked "A1305".The complementary NPN transistor to the 2SA1305 is the 2SC3297.You can replace the 2SA1305 with the 2SA1012, 2SA1262, 2SA1279, 2SA1288, 2SA1289, 2SA1290, 2SA1291, 2SA1307, 2SA1328, 2SA1451, 2SA1451A, 2SA1469, 2SA1470, 2SA1471, 2SA1488, 2SA1869, 2SA473, 2SA489, 2SA490, 2SA614, 2SA768, 2SA770, 2SB1019, 2SB1133, 2SB1134, 2SB1135, 2SB1136, 2SB1185, 2SB1187, 2SB1274, 2SB1548, 2SB434, 2SB435, 2SB507, 2SB553, 2SB761, 2SB762, 2SB824, 2SB825, 2SB826, 2SB834, 2SB857, 2SB858, 2SB903, 2SB919, 2SB941, 2SB942, 2SB947A, 2SB948A, 2SB993, 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, BD950, BDT82, BDT82F, D44C1, D44C2, D44C3, D44C4, D44C5, D44C6, D44C7, D44C8, D44C9, D45C1, D45C2, D45C3, D45C4, D45C5, D45C6, D45C7, D45C8, D45C9, D45H8, KSA473, KSA614, KTA1276, KTA1658 or KTB988.
