Here is an image showing the pin diagram of this transistor.The 2SA489-R transistor can have a current gain of 40 to 80. 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-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA489-R might only be marked "A489-R".The complementary NPN transistor to the 2SA489-R is the 2SC789-R.You can replace the 2SA489-R with the 2N6107, 2N6107G, 2N6110, 2N6125, 2N6126, 2N6133, 2N6134, 2N6475, 2N6476, 2N6490, 2N6490G, 2N6491, 2N6491G, 2SA1010, 2SA1010M, 2SA1262, 2SA1488, 2SA1488A, 2SA770, 2SA771, 2SB1016, 2SB1016-R, 2SB1017, 2SB1017-R, 2SB1090, 2SB1090-M, 2SB1097, 2SB1097-M, 2SB1367, 2SB1367-R, 2SB1368, 2SB1368-R, 2SB595, 2SB595-R, 2SB596, 2SB596-R, 2SB633, 2SB633-C, 2SB703, 2SB703-S, 2SB703A, 2SB703A-S, 2SB707, 2SB707-R, 2SB708, 2SB708-R, 2SB747, 2SB747-R, 2SB762, 2SB762-R, 2SB762A, 2SB762A-R, 2SB942, 2SB942-R, 2SB942A, 2SB942A-R, 2SB995, 2SB995-R, 2SB996, 2SB996-R, BD204, BD244A, BD244B, BD244C, BD304, BD536, BD536K, BD538, BD538K, BD540A, BD540B, BD540C, BD708, BD710, BD712, BD744A, BD744B, BD744C, BD798, BD800, BD802, BD808, BD810, BD908, BD910, BD912, BD950, BD952, BD954, BD956, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDT92, BDT92F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D44C10, D44C11, D44C12, D44C7, D44C8, D44C9, D45C10, D45C11, D45C12, D45C7, D45C8, D45C9, KSA1010, KSA1010R, KSB1017, KSB1017-R, KSB1097, KSB1097-R, KSB596, KSB596-R, KSB707, KSB707-R, KSB708, KSB708-R, KTB1367, KTB1367R, KTB1368, KTB1368R, MJE15029, MJE15029G, MJE2901T, MJE2955T, MJE2955TG, MJE5170, MJF2955, MJF2955G, NTE153 or NTE197.
