Here is an image showing the pin diagram of this transistor.The 2SA1048-Y transistor can have a current gain of 120 to 240. The gain of the 2SA1048 will be in the range from 70 to 400, for the 2SA1048-GR it will be in the range from 200 to 400, for the 2SA1048-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SA1048-Y might only be marked "A1048-Y".The complementary NPN transistor to the 2SA1048-Y is the 2SC2458-Y.The 2SA1037 (SOT-23), 2SA1037-Q (SOT-23), 2SA1162 (SOT-23), 2SA1162-Y (SOT-23), 2SA1586 (SOT-323), 2SA1586-Y (SOT-323), 2SA1832 (SOT-23), 2SA1832-Y (SOT-23), 2SA812 (SOT-23), FJX733 (SOT-323), FJX733Y (SOT-323), KSA812 (SOT-23), KTA1504 (SOT-23), KTA1504S (SOT-23), KTA1504S-Y (SOT-23), KTA1504Y (SOT-23) and TMBT3906 (SOT-23) is the SMD version of the 2SA1048-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1048-Y with the 2SA1015, 2SA1015Y, 2SA1020, 2SA1020Y, 2SA1246, 2SA1266, 2SA1266-Y, 2SA1267, 2SA1267-Y, 2SA1283, 2SA1284, 2SA1315, 2SA1315-Y, 2SA1317, 2SA1318, 2SA1391, 2SA1392, 2SA1450, 2SA1481, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534A, 2SA1534A-R, 2SA1619A, 2SA1619A-R, 2SA1680, 2SA200, 2SA200-Y, 2SA684, 2SA684-R, 2SA720, 2SA720-R, 2SA817, 2SA817-Y, 2SA817A, 2SA817A-Y, 2SA935, 2SA935-Q, 2SA953, 2SA954, 2SA984, 2SA984K, 2SA993, 2SB1229, 2SB560, 2SB647, 2SB740, 2SB764, 2SB892, 2SB985, A1015, A1015Y, A733, BC212, BC212A, H733, KSA1015, KSA1015Y, KSA1281-Y, KSA708C, KSA708CY, KSA733C, KSA733CY, KSA931, KSA931Y, KSP2907AC, KSP8598C, KSP8599C, KTA1266, KTA1266Y, KTA1267, KTA1267Y, KTA1274, KTA1274Y, KTA1281, KTA1281Y, KTA200, KTA200-Y, KTB764 or PN3645.
