Here is an image showing the pin diagram of this transistor.The 2SA614Y transistor can have a current gain of 120 to 240. The gain of the 2SA614 will be in the range from 40 to 240, for the 2SA614O it will be in the range from 70 to 140, for the 2SA614R it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SA614Y might only be marked "A614Y".The NZT660 (SOT-223) is the SMD version of the 2SA614Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA614Y with the 2SA1262, 2SA1288, 2SA1289, 2SA1290, 2SA1291, 2SA1293, 2SA1293-Y, 2SA1308, 2SA1308-Y, 2SA1329, 2SA1329-Y, 2SA1388, 2SA1388-Y, 2SA1452, 2SA1452-Y, 2SA1452A, 2SA1452A-Y, 2SA1469, 2SA1470, 2SA1471, 2SA1488, 2SA1488A, 2SA1634, 2SA1635, 2SA1742, 2SA1743, 2SA1744, 2SA489, 2SA489-Y, 2SA768, 2SA769, 2SA770, 2SA771, 2SB1016, 2SB1016-Y, 2SB1016A, 2SB1016A-Y, 2SB1017, 2SB1017-Y, 2SB1018, 2SB1018-Y, 2SB1018A, 2SB1018A-Y, 2SB1133, 2SB1187, 2SB1274, 2SB1367, 2SB1367-Y, 2SB1368, 2SB1368-Y, 2SB1375, 2SB1548, 2SB1548-P, 2SB1548A, 2SB1548A-P, 2SB1565, 2SB507, 2SB595, 2SB595-Y, 2SB596, 2SB596-Y, 2SB633, 2SB761, 2SB761-P, 2SB761A, 2SB761A-P, 2SB762, 2SB762-P, 2SB762A, 2SB762A-P, 2SB834, 2SB858, 2SB870, 2SB941, 2SB941-P, 2SB941A, 2SB941A-P, 2SB942, 2SB942-P, 2SB942A, 2SB942A-P, 2SB943, 2SB944, 2SB945, 2SB946, 2SB992, 2SB992-Y, 2SB995, 2SB995-Y, 2SB996, 2SB996-Y, BD204, BD242A, BD242B, BD242C, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD798, BD800, BD802, BD808, BD810, BD936, BD936F, BD938, BD938F, BD940, BD940F, BD950, BD952, BD954, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, KSA614, KSA614Y, KSB1017, KSB1017-Y, KSB1366, KSB596, KSB596-Y, KTA1036, KTA1038, KTA1038-Y, KTA1049, KTA1049Y, KTB1367, KTB1367Y, KTB1368, KTB1368Y, KTB988, TTA1452B or TTB1452B.
