Here is an image showing the pin diagram of this transistor.The 2SB993-Y transistor can have a current gain of 120 to 240. The gain of the 2SB993 will be in the range from 70 to 240, for the 2SB993-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SB993-Y might only be marked "B993-Y".The complementary NPN transistor to the 2SB993-Y is the 2SD1363-Y.You can replace the 2SB993-Y with the 2SA1290, 2SA1291, 2SA1328, 2SA1328-Y, 2SA1329, 2SA1329-Y, 2SA1451, 2SA1451-Y, 2SA1451A, 2SA1451A-Y, 2SA1452, 2SA1452-Y, 2SA1452A, 2SA1452A-Y, 2SA1470, 2SA1471, 2SA1742, 2SA1743, 2SA1744, 2SB1018, 2SB1018-Y, 2SB1018A, 2SB1018A-Y, 2SB1019, 2SB1019-Y, 2SB1135, 2SB1136, 2SB553, 2SB553-Y, 2SB825, 2SB826, 2SB870, 2SB946, 2SB992, 2SB992-Y, BD204, BD304, BD536, BD538, BD544A, BD544B, BD544C, BD546A, BD546B, BD546C, BD798, BD800, BD802, BD808, BD810, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, BDX78, D45H11, D45H11FP, D45H8, TTA1452B or TTB1452B.
