Here is an image showing the pin diagram of this transistor.The 2SB919 transistor can have a current gain of 70 to 280. The gain of the 2SB919-Q will be in the range from 70 to 140, 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 might only be marked "B919".The complementary NPN transistor to the 2SB919 is the 2SD1235.You can replace the 2SB919 with the 2SA1291, 2SA1471, 2SB1136, 2SB826, 2SB903, BD202, BD204, BD302, BD304, BD534, BD536, BD544, BD544A, BD546, BD546A, BD796, BD798, BD808, BDT82, BDT82F or D45H8.
