Here is an image showing the pin diagram of this transistor.The 2SA1094-O transistor can have a current gain of 80 to 160. The gain of the 2SA1094 will be in the range from 55 to 240, for the 2SA1094-R it will be in the range from 55 to 110, for the 2SA1094-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA1094-O might only be marked "A1094-O".The complementary NPN transistor to the 2SA1094-O is the 2SC2564-O.You can replace the 2SA1094-O with the 2SA1076, 2SA1095, 2SA1095-O, 2SA1169, 2SA1187, 2SA1215, 2SA1216, 2SA1493, 2SA1494, 2SB755 or 2SB755-O.
