Here is an image showing the pin diagram of this transistor.The 2SA489-Y transistor can have a current gain of 120 to 240. The gain of the 2SA489 will be in the range from 40 to 240, for the 2SA489-O it will be in the range from 70 to 140, for the 2SA489-R it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SA489-Y might only be marked "A489-Y".The complementary NPN transistor to the 2SA489-Y is the 2SC789-Y.The NZT660 (SOT-223) is the SMD version of the 2SA489-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA489-Y with the 2SA1262, 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, 2SA768, 2SA769, 2SA770, 2SA771, 2SB1016, 2SB1016-Y, 2SB1016A, 2SB1016A-Y, 2SB1017, 2SB1017-Y, 2SB1018, 2SB1018-Y, 2SB1018A, 2SB1018A-Y, 2SB1367, 2SB1367-Y, 2SB1368, 2SB1368-Y, 2SB595, 2SB595-Y, 2SB596, 2SB596-Y, 2SB633, 2SB762, 2SB762-P, 2SB762A, 2SB762A-P, 2SB858, 2SB870, 2SB942, 2SB942-P, 2SB942A, 2SB942A-P, 2SB944, 2SB945, 2SB946, 2SB992, 2SB992-Y, 2SB995, 2SB995-Y, 2SB996, 2SB996-Y, BD204, BD244A, BD244B, BD244C, BD304, BD536, BD538, BD540A, BD540B, BD540C, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD798, BD800, BD802, BD808, BD810, BD950, BD952, BD954, BD956, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8, D45C9, D45H11, D45H11FP, D45H8, KSB1017, KSB1017-Y, KSB596, KSB596-Y, KTA1038, KTA1038-Y, KTA1049, KTA1049Y, KTB1367, KTB1367Y, KTB1368, KTB1368Y, MJE15029, MJE15029G, TTA1452B or TTB1452B.
