Here is an image showing the pin diagram of this transistor.The 2SB1019-O transistor can have a current gain of 70 to 140. The gain of the 2SB1019 will be in the range from 70 to 240, for the 2SB1019-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SB1019-O might only be marked "B1019-O".The complementary NPN transistor to the 2SB1019-O is the 2SD1412-O.You can replace the 2SB1019-O with the 2N6107, 2N6107G, 2N6108, 2N6109, 2N6109G, 2N6110, 2N6490, 2N6490G, 2N6491, 2N6491G, 2SA1010, 2SA1290, 2SA1290-Q, 2SA1291, 2SA1291-Q, 2SA1328, 2SA1328-O, 2SA1329, 2SA1329-O, 2SA1451, 2SA1451-O, 2SA1451A, 2SA1451A-O, 2SA1452, 2SA1452-O, 2SA1452A, 2SA1452A-O, 2SA1470, 2SA1470-Q, 2SA1471, 2SA1471-Q, 2SB1018, 2SB1018-O, 2SB1018A, 2SB1018A-O, 2SB1097, 2SB1135, 2SB1135-Q, 2SB1136, 2SB1136-Q, 2SB553, 2SB553-O, 2SB707, 2SB708, 2SB825, 2SB825-Q, 2SB826, 2SB826-Q, 2SB870, 2SB946, 2SB992, 2SB992-O, 2SB993, 2SB993-O, BD204, BD304, BD536, BD538, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD708, BD710, BD712, BD744A, BD744B, BD744C, BD798, BD800, BD802, BD808, BD810, BD908, BD910, BD912, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT92, BDT92F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D45H11, D45H11FP, D45H8, KSA1010, KSB1097, KSB707, KSB708 or NTE197.
