Here is an image showing the pin diagram of this transistor.The 2SB1018A-O transistor can have a current gain of 70 to 140. The gain of the 2SB1018A will be in the range from 70 to 240, for the 2SB1018A-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SB1018A-O might only be marked "B1018A-O".The complementary NPN transistor to the 2SB1018A-O is the 2SD1411A-O.You can replace the 2SB1018A-O with the 2N6491, 2N6491G, 2SA1010, 2SA1077, 2SA1329, 2SA1329-O, 2SA1452, 2SA1452-O, 2SA1452A, 2SA1452A-O, 2SB1018, 2SB1018-O, 2SB708, 2SB870, 2SB946, 2SB992, 2SB992-O, BD538, BD544B, BD544C, BD546B, BD546C, BD710, BD712, BD744B, BD744C, BD800, BD802, BD810, BD910, BD912, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D45H11, D45H11FP, KSA1010, KSB708, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
