Here is an image showing the pin diagram of this transistor.The 2SA1619-Q transistor can have a current gain of 80 to 170. The gain of the 2SA1619 will be in the range from 80 to 340, 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-Q might only be marked "A1619-Q".The complementary NPN transistor to the 2SA1619-Q is the 2SA1619-Q.The 2SA1182 (SOT-23), 2SA1588 (SOT-323), FJX1182 (SOT-323), KSA1182 (SOT-23), KTA1505 (SOT-23) and KTA1505S (SOT-23) is the SMD version of the 2SA1619-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1619-Q with the 2N3702, 2N4951, 2N4954, 2SA1020, 2SA1270, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1619A, 2SA1619A-Q, 2SA200, 2SA562TM, 2SA984, 2SA993, 2SB598, 2SB764, BC636, KSB564AC, KSB810, KSB811, KTA1270, KTA1281, KTA200, KTB764, MPS3638, PN3638 or PN3644.
