Here is an image showing the pin diagram of this transistor.The 2SA1175-HF transistor can have a current gain of 170 to 270. 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-JF it will be in the range from 135 to 220, for the 2SA1175-KF it will be in the range from 300 to 600, 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-HF might only be marked "A1175-HF".The complementary NPN transistor to the 2SA1175-HF is the 2SC2785-HF.The 2SA812 (SOT-23), 2SA812-M5 (SOT-23), KSA812 (SOT-23) and KSA812-Y (SOT-23) is the SMD version of the 2SA1175-HF transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1175-HF with the 2SA1015, 2SA1032, 2SA1032-C, 2SA1048, 2SA1246, 2SA1246-S, 2SA1266, 2SA1267, 2SA1283, 2SA1283-E, 2SA1284, 2SA1284-E, 2SA1317, 2SA1317-S, 2SA1318, 2SA1318-S, 2SA1382, 2SA1391, 2SA1391-S, 2SA1392, 2SA1392-S, 2SA1450, 2SA1450-S, 2SA1481, 2SA1481-F, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534A, 2SA1534A-S, 2SA1619A, 2SA1619A-S, 2SA1680, 2SA1761, 2SA608N, 2SA608N-F, 2SA684, 2SA684-S, 2SA720, 2SA720-S, 2SA733, 2SA733Q, 2SA935, 2SA935-Q, 2SA953, 2SA953-L, 2SA954, 2SA954-L, 2SA984, 2SA984-F, 2SA984K, 2SA984K-F, 2SA993, 2SA993D, 2SB1116, 2SB1116-L, 2SB1116A, 2SB1116A-L, 2SB1229, 2SB1229-S, 2SB560, 2SB560-F, 2SB647, 2SB647D, 2SB740, 2SB740-C, 2SB764, 2SB764-F, 2SB892, 2SB892-S, 2SB985, 2SB985S, A1015, A733, A733Q, BC212, BC212A, H733, H733-Q, KSA1015, KSA708C, KSA733C, KSB1116, KSB1116-Y, KSB1116A, KSB1116A-Y, KSB1116S, KSB1116S-Y, KSP2907AC, KSP8598C, KSP8599C, KTA1266, KTA1267, KTB764, KTB764-GR or NTE383.
