Here is an image showing the pin diagram of this transistor.The 2SA1175-EF transistor can have a current gain of 250 to 400. The gain of the 2SA1175 will be in the range from 110 to 600, 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-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-EF might only be marked "A1175-EF".The complementary NPN transistor to the 2SA1175-EF is the 2SC2785-EF.The 2SA812 (SOT-23), 2SA812-M6 (SOT-23), KSA812 (SOT-23) and KSA812-G (SOT-23) is the SMD version of the 2SA1175-EF transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1175-EF with the 2SA1015, 2SA1015GR, 2SA1025, 2SA1025-D, 2SA1048, 2SA1048-GR, 2SA1081, 2SA1081-D, 2SA1083, 2SA1083-D, 2SA1084, 2SA1084-D, 2SA1127, 2SA1246, 2SA1246-T, 2SA1266, 2SA1266-GR, 2SA1267, 2SA1267-G, 2SA1267-GR, 2SA1316, 2SA1316-GR, 2SA1317, 2SA1317-T, 2SA1318, 2SA1318-T, 2SA1382, 2SA1391, 2SA1391-T, 2SA1392, 2SA1392-T, 2SA1450, 2SA1450-T, 2SA1481, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1680, 2SA1761, 2SA608N, 2SA733, 2SA733P, 2SA953, 2SA953-K, 2SA954, 2SA954-K, 2SA990, 2SA990P, 2SA991, 2SA991P, 2SB1116, 2SB1116-K, 2SB1116A, 2SB1116A-K, 2SB1229, 2SB1229-T, 2SB560, 2SB726, 2SB892, 2SB892-T, 2SB985, 2SB985T, A1015, A1015GR, A733, A733P, BC212, BC212B, H733, H733-P, KSA1015, KSA1015GR, KSA708C, KSA733C, KSA733CG, KSB1116, KSB1116-G, KSB1116A, KSB1116A-G, KSB1116S, KSB1116S-G, KTA1266, KTA1266GR, KTA1267, KTA1267GR or NTE193A.
