Here is an image showing the pin diagram of this transistor.The 2SB919-Q transistor can have a current gain of 70 to 140. The gain of the 2SB919 will be in the range from 70 to 280, for the 2SB919-R it will be in the range from 100 to 200, for the 2SB919-S it will be in the range from 140 to 280.Sometimes the "2S" prefix is not marked on the package - the 2SB919-Q might only be marked "B919-Q".The complementary NPN transistor to the 2SB919-Q is the 2SD1235-Q.You can replace the 2SB919-Q with the 2N6489, 2N6489G, 2N6490, 2N6490G, 2SA1291, 2SA1291-Q, 2SA1328, 2SA1328-O, 2SA1451, 2SA1451-O, 2SA1451A, 2SA1451A-O, 2SA1471, 2SA1471-Q, 2SB1136, 2SB1136-Q, 2SB826, 2SB826-Q, 2SB903, 2SB903-Q, 2SB947A, 2SB948A, BD202, BD204, BD302, BD304, BD534, BD536, BD544, BD544A, BD546, BD546A, BD706, BD708, BD744, BD744A, BD796, BD798, BD808, BD906, BD908, BDT82, BDT82F, BDT92, BDT92F or D45H8.
