Here is an image showing the pin diagram of this transistor.The 2SA1451-Y transistor can have a current gain of 120 to 240. The gain of the 2SA1451 will be in the range from 70 to 240, for the 2SA1451-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1451-Y might only be marked "A1451-Y".The complementary NPN transistor to the 2SA1451-Y is the 2SC3709-Y.You can replace the 2SA1451-Y with the 2SA1328, 2SA1328-Y, 2SA1329, 2SA1329-Y, 2SA1451A, 2SA1451A-Y, 2SA1452, 2SA1452-Y, 2SA1452A, 2SA1452A-Y, 2SA1744, 2SB1136, 2SB826, BD546A, BD546B, BD546C, BDT82, BDT82F, BDT84, BDT84F, BDT86, BDT86F, TTA1452B or TTB1452B.
