Here is an image showing the pin diagram of this transistor.The 2SA1048-O transistor can have a current gain of 70 to 140. 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-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1048-O might only be marked "A1048-O".The complementary NPN transistor to the 2SA1048-O is the 2SC2458-O.The 2SA1162 (SOT-23), 2SA1162-O (SOT-23), 2SA1586 (SOT-323), 2SA1586-O (SOT-323), 2SA1832 (SOT-23), 2SA1832-O (SOT-23), FJX733 (SOT-323), FJX733O (SOT-323), KTA1504 (SOT-23), KTA1504O (SOT-23), KTA1504S (SOT-23) and KTA1504S-O (SOT-23) is the SMD version of the 2SA1048-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1048-O with the 2SA1015, 2SA1015O, 2SA1020, 2SA1020O, 2SA1266, 2SA1266-O, 2SA1267, 2SA1267-O, 2SA1283, 2SA1284, 2SA1315, 2SA1315-O, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA200, 2SA200-O, 2SA817, 2SA817-O, 2SA817A, 2SA817A-O, 2SA984, 2SA984K, 2SA993, 2SB560, 2SB647, 2SB647A, 2SB764, A1015, A1015O, BC212, BC638, BC640, KSA1015, KSA1015O, KSA708C, KSA708CO, KSA733C, KSA733CO, KSA931, KSA931O, KTA1266, KTA1266O, KTA1267, KTA1267O, KTA1274, KTA1274O, KTA1281, KTA1281O, KTA200, KTA200-O, KTA708 or KTB764.
