Here is an image showing the pin diagram of this transistor.The 2SA1012O transistor can have a current gain of 70 to 140. The gain of the 2SA1012 will be in the range from 70 to 240, for the 2SA1012Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1012O might only be marked "A1012O".The complementary NPN transistor to the 2SA1012O is the 2SC2562O.You can replace the 2SA1012O with the 2N6107, 2N6107G, 2N6108, 2N6109, 2N6109G, 2N6110, 2N6490, 2N6490G, 2N6491, 2N6491G, 2SA1010, 2SA1279, 2SA1279-O, 2SA1289, 2SA1289-Q, 2SA1290, 2SA1290-Q, 2SA1291, 2SA1291-Q, 2SA1293, 2SA1293-O, 2SA1307, 2SA1307-O, 2SA1308, 2SA1308-O, 2SA1328, 2SA1328-O, 2SA1329, 2SA1329-O, 2SA1388, 2SA1388-O, 2SA1451, 2SA1451-O, 2SA1451A, 2SA1451A-O, 2SA1452, 2SA1452-O, 2SA1452A, 2SA1452A-O, 2SA1469, 2SA1469-Q, 2SA1470, 2SA1470-Q, 2SA1471, 2SA1471-Q, 2SA1725, 2SA1725-P, 2SA1726, 2SA1726-P, 2SA770, 2SA771, 2SB1016, 2SB1016-O, 2SB1016A, 2SB1016A-O, 2SB1018, 2SB1018-O, 2SB1018A, 2SB1018A-O, 2SB1019, 2SB1019-O, 2SB1097, 2SB1134, 2SB1134-Q, 2SB1135, 2SB1135-Q, 2SB1136, 2SB1136-Q, 2SB1367, 2SB1367-O, 2SB553, 2SB553-O, 2SB595, 2SB595-O, 2SB633, 2SB707, 2SB708, 2SB747, 2SB824, 2SB824-Q, 2SB825, 2SB825-Q, 2SB826, 2SB826-Q, 2SB870, 2SB945, 2SB946, 2SB992, 2SB992-O, 2SB993, 2SB993-O, 2SB995, 2SB995-O, BD204, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD708, BD710, BD712, BD744A, BD744B, BD744C, BD798, BD800, BD802, BD808, BD810, BD908, BD910, BD912, BD950, BD952, BD954, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT92, BDT92F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D45H11, D45H11FP, D45H8, KSA1010, KSB1097, KSB707, KSB708, KTA1038, KTA1038-O, KTA1049, KTA1049O, KTB1367, KTB1367O or NTE197.
