Here is an image showing the pin diagram of this transistor.The 2SA1494-P transistor can have a current gain of 70 to 140. The gain of the 2SA1494 will be in the range from 50 to 180, for the 2SA1494-O it will be in the range from 50 to 100, for the 2SA1494-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA1494-P might only be marked "A1494-P".The complementary NPN transistor to the 2SA1494-P is the 2SC3858-P.You can replace the 2SA1494-P with the 2SA1170, 2SA1170-Y, 2SA1295 or 2SA1295-Y.
