Here is an image showing the pin diagram of this transistor.The 2SA1174-P transistor can have a current gain of 200 to 400. The gain of the 2SA1174 will be in the range from 200 to 800, for the 2SA1174-E it will be in the range from 400 to 800, for the 2SA1174-F it will be in the range from 300 to 600.Sometimes the "2S" prefix is not marked on the package - the 2SA1174-P might only be marked "A1174-P".The complementary NPN transistor to the 2SA1174-P is the 2SC2784-P.You can replace the 2SA1174-P with the 2SA1016, 2SA1016K, 2SA1017, 2SA1049, 2SA1049-GR, 2SA1269, 2SA1269-GR, 2SA1285, 2SA1316, 2SA1316-GR, 2SA1450, 2SA1450-T, 2SA953, 2SA953-K, 2SA954, 2SA954-K, 2SA970, 2SA970-GR, 2SA991, 2SA991P, 2SA992, 2SA992P, 2SB1116A, 2SB1116A-K, 2SB560, 2SB726, KSA708C, KSA992, KSA992P, KSB1116A or KSB1116A-G.
