Here is an image showing the pin diagram of this transistor.The 2SA1305-O transistor can have a current gain of 70 to 140. The gain of the 2SA1305 will be in the range from 70 to 240, 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-O might only be marked "A1305-O".The complementary NPN transistor to the 2SA1305-O is the 2SC3297-O.You can replace the 2SA1305-O with the 2N6106, 2N6108, 2N6109, 2N6109G, 2N6111, 2N6111G, 2N6489, 2N6489G, 2N6490, 2N6490G, 2SA1012, 2SA1012O, 2SA1262, 2SA1279, 2SA1279-O, 2SA1288, 2SA1288-Q, 2SA1289, 2SA1289-Q, 2SA1290, 2SA1290-Q, 2SA1291, 2SA1291-Q, 2SA1307, 2SA1307-O, 2SA1328, 2SA1328-O, 2SA1451, 2SA1451-O, 2SA1451A, 2SA1451A-O, 2SA1469, 2SA1469-Q, 2SA1470, 2SA1470-Q, 2SA1471, 2SA1471-Q, 2SA1488, 2SA1869, 2SA1869O, 2SA473, 2SA473O, 2SA489, 2SA489-O, 2SA490, 2SA490-O, 2SA614, 2SA614O, 2SA671, 2SA768, 2SA770, 2SB1015, 2SB1019, 2SB1019-O, 2SB1097, 2SB1133, 2SB1133-Q, 2SB1134, 2SB1134-Q, 2SB1135, 2SB1135-Q, 2SB1136, 2SB1136-Q, 2SB1185, 2SB1187, 2SB1274, 2SB1366, 2SB1548, 2SB1548-Q, 2SB434, 2SB434O, 2SB435, 2SB435-O, 2SB507, 2SB553, 2SB553-O, 2SB565, 2SB566, 2SB566A, 2SB707, 2SB761, 2SB761-Q, 2SB762, 2SB762-Q, 2SB824, 2SB824-Q, 2SB825, 2SB825-Q, 2SB826, 2SB826-Q, 2SB834, 2SB857, 2SB858, 2SB903, 2SB903-Q, 2SB919, 2SB919-Q, 2SB941, 2SB941-Q, 2SB942, 2SB942-Q, 2SB947A, 2SB948A, 2SB993, 2SB993-O, 2SB994, BD202, BD204, BD242, BD242A, BD244, BD244A, BD302, BD304, BD534, BD536, BD540, BD540A, BD544, BD544A, BD546, BD546A, BD706, BD708, BD736, BD738, BD744, BD744A, BD796, BD798, BD808, BD906, BD908, BD934, BD934F, BD936, BD936F, BD950, BDT82, BDT82F, BDT92, BDT92F, D44C1, D44C2, D44C3, D44C4, D44C5, D44C6, D44C7, D44C8, D44C9, D45C1, D45C2, D45C3, D45C4, D45C5, D45C6, D45C7, D45C8, D45C9, D45H8, KSA473, KSA473O, KSA614, KSA614O, KSB1015, KSB1097, KSB707, KSB834, KTA1276, KTA1276O, KTA1658, KTA1658O, KTB1366 or KTB988.
