Here is an image showing the pin diagram of this transistor.The 2SA1619A-S transistor can have a current gain of 170 to 340. The gain of the 2SA1619A will be in the range from 80 to 340, for the 2SA1619A-Q it will be in the range from 80 to 170, for the 2SA1619A-R it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1619A-S might only be marked "A1619A-S".The complementary NPN transistor to the 2SA1619A-S is the 2SC4208A-S.The 2SB710A (SOT-23), 2SB710A-S (SOT-23), FMMTA55 (SOT-23), KST55 (SOT-23), MMBTA55 (SOT-23), PZTA55 (SOT-223) and SMBTA55 (SOT-23) is the SMD version of the 2SA1619A-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1619A-S with the 2SA1382, 2SA1450, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534A, 2SA1534A-S, 2SA1680, 2SA1761, 2SA684, 2SA684-S, 2SA720, 2SA720-S, 2SA935, 2SB1116, 2SB1116A, 2SB1229, 2SB560, 2SB892, 2SB985, KSA708C, KSB1116, KSB1116A or KSB1116S.
