Here is an image showing the pin diagram of this transistor.The 2SA1619 transistor can have a current gain of 80 to 340. The gain of the 2SA1619-Q will be in the range from 80 to 170, for the 2SA1619-R it will be in the range from 120 to 240, for the 2SA1619-S it will be in the range from 170 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SA1619 might only be marked "A1619".The complementary NPN transistor to the 2SA1619 is the 2SA1619.The 2SA1588 (SOT-323), KTA1505 (SOT-23) and KTA1505S (SOT-23) is the SMD version of the 2SA1619 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1619 with the 2N4954, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1619A, 2SB598, KSB564AC, KSB810, KSB811, MPS3638 or PN3638.
