Here is an image showing the pin diagram of this transistor.The 2SA1187-P transistor can have a current gain of 70 to 140. The gain of the 2SA1187 will be in the range from 50 to 180, for the 2SA1187-O it will be in the range from 50 to 100, for the 2SA1187-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA1187-P might only be marked "A1187-P".The complementary NPN transistor to the 2SA1187-P is the 2SC2838-P.You can replace the 2SA1187-P with the 2SA1076, 2SA1095, 2SA1169, 2SA1169-P, 2SA1170, 2SA1170-Y, 2SA1215, 2SA1215-P, 2SA1216, 2SA1216-P, 2SA1295, 2SA1295-Y, 2SA1493, 2SA1493-P, 2SA1494, 2SA1494-P or 2SB755.
