Here is an image showing the pin diagram of this transistor.The 2SB1018A transistor can have a current gain of 70 to 240. The gain of the 2SB1018A-O will be in the range from 70 to 140, 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 might only be marked "B1018A".The complementary NPN transistor to the 2SB1018A is the 2SD1411A.You can replace the 2SB1018A with the 2SA1329, 2SA1452, 2SA1452A, 2SB1018, 2SB870, 2SB946, 2SB992, BD538, BD544B, BD544C, BD546B, BD546C, BD800, BD802, BD810, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDX78, D45H11, D45H11FP, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
