Here is an image showing the pin diagram of this transistor.The 2SA1175-KF transistor can have a current gain of 300 to 600. The gain of the 2SA1175 will be in the range from 110 to 600, for the 2SA1175-EF it will be in the range from 250 to 400, for the 2SA1175-FF it will be in the range from 200 to 320, for the 2SA1175-HF it will be in the range from 170 to 270, for the 2SA1175-JF it will be in the range from 135 to 220, for the 2SA1175-RF it will be in the range from 110 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA1175-KF might only be marked "A1175-KF".The complementary NPN transistor to the 2SA1175-KF is the 2SC2785-KF.The 2SA812 (SOT-23), 2SA812-M7 (SOT-23), KSA812 (SOT-23) and KSA812-L (SOT-23) is the SMD version of the 2SA1175-KF transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1175-KF with the 2SA1025, 2SA1081, 2SA1083, 2SA1084, 2SA1127, 2SA1316, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA733, 2SA733K, 2SA990, 2SA990F, 2SA991, 2SA991F, 2SB1116, 2SB1116-U, 2SB1116A-U, 2SB726, A733, A733K, H733, H733-K, KSA733C, KSB1116, KSB1116-L, KSB1116S or KSB1116S-L.
