Here is an image showing the pin diagram of this transistor.The 2SA1619A-Q transistor can have a current gain of 80 to 170. The gain of the 2SA1619A will be in the range from 80 to 340, for the 2SA1619A-R it will be in the range from 120 to 240, for the 2SA1619A-S it will be in the range from 170 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SA1619A-Q might only be marked "A1619A-Q".The complementary NPN transistor to the 2SA1619A-Q is the 2SC4208A-Q.The FMMTA55 (SOT-23) and KST55 (SOT-23) is the SMD version of the 2SA1619A-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1619A-Q with the 2SA1020, 2SA1283, 2SA1284, 2SA1315, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA200, 2SA984, 2SA984K, 2SA993, 2SB560, 2SB647, 2SB647A, 2SB764, KSA708C, KSA931, KTA1281, KTA200, KTA708, KTB764 or PN3645.
