Here is an image showing the pin diagram of this transistor.The 2SA1175-RF transistor can have a current gain of 110 to 180. 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-KF it will be in the range from 300 to 600.Sometimes the "2S" prefix is not marked on the package - the 2SA1175-RF might only be marked "A1175-RF".The complementary NPN transistor to the 2SA1175-RF is the 2SC2785-RF.The 2SA812 (SOT-23), 2SA812-M4 (SOT-23), KSA812 (SOT-23) and KSA812-O (SOT-23) is the SMD version of the 2SA1175-RF transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1175-RF with the 2SA1015, 2SA1020, 2SA1032, 2SA1032-B, 2SA1048, 2SA1246, 2SA1246-R, 2SA1266, 2SA1267, 2SA1283, 2SA1283-D, 2SA1284, 2SA1284-D, 2SA1315, 2SA1317, 2SA1317-R, 2SA1318, 2SA1318-R, 2SA1391, 2SA1391-R, 2SA1392, 2SA1392-R, 2SA1450, 2SA1450-R, 2SA1481, 2SA1481-E, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1533, 2SA1534A, 2SA1619A, 2SA200, 2SA684, 2SA720, 2SA733, 2SA733R, 2SA777, 2SA817, 2SA817A, 2SA935, 2SA935-P, 2SA953, 2SA953-M, 2SA954, 2SA954-M, 2SA984, 2SA984-E, 2SA984K, 2SA984K-E, 2SA993, 2SA993C, 2SB1229, 2SB1229-R, 2SB560, 2SB560-E, 2SB647, 2SB647A, 2SB647AC, 2SB647C, 2SB740, 2SB740-B, 2SB764, 2SB764-E, 2SB892, 2SB892-R, 2SB985, 2SB985R, A1015, A733, A733R, BC212, BC212A, H733, H733-R, KSA1015, KSA708C, KSA733C, KSA931, KSP2907AC, KSP8598C, KSP8599C, KTA1266, KTA1267, KTA1274, KTA1281, KTA200, KTA708, KTA708-Y, KTB764, KTB764-Y or PN3645.
