Here is an image showing the pin diagram of this transistor.The KSA473 transistor can have a current gain of 70 to 240. The gain of the KSA473O will be in the range from 70 to 140, for the KSA473Y it will be in the range from 120 to 240.The complementary NPN transistor to the KSA473 is the KSC1173.You can replace the KSA473 with the 2SA1012, 2SA1262, 2SA1279, 2SA1288, 2SA1289, 2SA1290, 2SA1291, 2SA1305, 2SA1307, 2SA1328, 2SA1451, 2SA1451A, 2SA1469, 2SA1470, 2SA1471, 2SA1488, 2SA1869, 2SA473, 2SA489, 2SA490, 2SA614, 2SA768, 2SA770, 2SB1019, 2SB1133, 2SB1134, 2SB1135, 2SB1136, 2SB1185, 2SB1187, 2SB1274, 2SB1548, 2SB434, 2SB435, 2SB507, 2SB553, 2SB761, 2SB762, 2SB824, 2SB825, 2SB826, 2SB834, 2SB857, 2SB858, 2SB903, 2SB919, 2SB941, 2SB942, 2SB947A, 2SB948A, 2SB993, BD202, BD204, BD242, BD242A, BD244, BD244A, BD302, BD304, BD534, BD536, BD540, BD540A, BD544, BD544A, BD546, BD546A, BD736, BD738, BD796, BD798, BD808, BD934, BD934F, BD936, BD936F, BD950, BDT82, BDT82F, D44C1, D44C2, D44C3, D44C4, D44C5, D44C6, D44C7, D44C8, D44C9, D45C1, D45C2, D45C3, D45C4, D45C5, D45C6, D45C7, D45C8, D45C9, D45H8, KSA614, KTA1276, KTA1658 or KTB988.
