Here is an image showing the pin diagram of this transistor.The 2SA1049-GR transistor can have a current gain of 200 to 400. The gain of the 2SA1049 will be in the range from 200 to 700, for the 2SA1049-BL it will be in the range from 350 to 700.Sometimes the "2S" prefix is not marked on the package - the 2SA1049-GR might only be marked "A1049-GR".The complementary NPN transistor to the 2SA1049-GR is the 2SC2459-GR.The 2SA1163 (SOT-23), 2SA1163-GR (SOT-23), 2SA1312 (SOT-23), 2SA1312-GR (SOT-23), 2SA1587 (SOT-323), 2SA1587-GR (SOT-323), FJV992 (SOT-23), FJV992-P (SOT-23) and FJX992 (SOT-323) is the SMD version of the 2SA1049-GR transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1049-GR with the 2SA1269, 2SA1269-GR, 2SA1285, 2SA1285A, 2SA1319, 2SA1319-T, 2SA1376, 2SA1376-K, 2SA1376A, 2SA1376A-K, 2SA970, 2SA970-GR, KSA709C or KSA709CG.
