Here is an image showing the pin diagram of this transistor.The 2SA1174 transistor can have a current gain of 200 to 800. The gain of the 2SA1174-E will be in the range from 400 to 800, for the 2SA1174-F it will be in the range from 300 to 600, for the 2SA1174-P it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SA1174 might only be marked "A1174".The complementary NPN transistor to the 2SA1174 is the 2SC2784.You can replace the 2SA1174 with the 2SA1016, 2SA1016K, 2SA1285, 2SA991, 2SA992 or KSA992.
