Here is an image showing the pin diagram of this transistor.The 2SA887-R transistor can have a current gain of 120 to 220. The gain of the 2SA887 will be in the range from 50 to 220, for the 2SA887-P it will be in the range from 50 to 100, for the 2SA887-Q it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SA887-R might only be marked "A887-R".The complementary NPN transistor to the 2SA887-R is the 2SC1848-R.The BSP31 (SOT-223), BSR31 (SOT-89), FMMT591 (SOT-23), FMMT591Q (SOT-23), KTA1668 (SOT-89) and KTA1668Y (SOT-89) is the SMD version of the 2SA887-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA887-R with the 2SA636A, 2SA636A-K or NTE187.
