Here is an image showing the pin diagram of this transistor.The 2SA1726-Y transistor can have a current gain of 90 to 180. The gain of the 2SA1726 will be in the range from 50 to 180, for the 2SA1726-O it will be in the range from 50 to 100, for the 2SA1726-P it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1726-Y might only be marked "A1726-Y".The complementary NPN transistor to the 2SA1726-Y is the 2SC4512-Y.The BDP952 (SOT-223) is the SMD version of the 2SA1726-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1726-Y with the 2SA1010, 2SA1077, 2SA1329, 2SA1452, 2SA1452A, 2SA1725, 2SA1725-Y, 2SA771, 2SB1018, 2SB1018A, 2SB633, 2SB708, 2SB870, 2SB870-Q, 2SB946, 2SB946-Q, 2SB992, BD244B, BD244C, BD538, BD544B, BD544C, BD546B, BD546C, BD800, BD802, BD810, BDT84, BDT84F, BDT86, BDT86F, BDT88, BDT88F, BDT94, BDT94F, BDT96, BDT96F, BDX78, D45H11, D45H11FP, KSA1010, KSB708, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
