Here is an image showing the pin diagram of this transistor.The 2SA1619-S transistor can have a current gain of 170 to 340. The gain of the 2SA1619 will be in the range from 80 to 340, for the 2SA1619-Q it will be in the range from 80 to 170, for the 2SA1619-R it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1619-S might only be marked "A1619-S".The complementary NPN transistor to the 2SA1619-S is the 2SA1619-S.The 2SA1588 (SOT-323), BC808 (SOT-23), BC808-25 (SOT-23), BC808-25W (SOT-323), BC808W (SOT-323), KTA1505 (SOT-23) and KTA1505S (SOT-23) is the SMD version of the 2SA1619-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1619-S with the 2N4954, 2SA1382, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534, 2SA1534-S, 2SA1534A, 2SA1534A-S, 2SA1619A, 2SA1619A-S, 2SA1680, 2SA1761, 2SA683, 2SA683-S, 2SA684, 2SA684-S, 2SA719, 2SA719-S, 2SA720, 2SA720-S, 2SA952, 2SB1116, 2SB1229, 2SB564, 2SB598, 2SB621, 2SB621-S, 2SB621A, 2SB621A-S, 2SB892, 2SB985, KSB1116, KSB1116S, KSB564AC, KSB810, KSB811, MPS3638, MPS3638A, PN3638 or PN3638A.
