Here is an image showing the pin diagram of this transistor.The 2SA887 transistor can have a current gain of 50 to 220. The gain of the 2SA887-P will be in the range from 50 to 100, for the 2SA887-Q it will be in the range from 80 to 160, for the 2SA887-R it will be in the range from 120 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SA887 might only be marked "A887".The complementary NPN transistor to the 2SA887 is the 2SC1848.You can replace the 2SA887 with the 2SA636A.
