Here is an image showing the pin diagram of this transistor.The 2SA887-P transistor can have a current gain of 50 to 100. The gain of the 2SA887 will be in the range from 50 to 220, 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-P might only be marked "A887-P".The complementary NPN transistor to the 2SA887-P is the 2SC1848-P.The BSR30 (SOT-89) and FMMT551 (SOT-23) is the SMD version of the 2SA887-P transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA887-P with the 2SA636A or 2SA636A-M.
