Here is an image showing the pin diagram of this transistor.The 2SD1486-R transistor can have a current gain of 40 to 80. The gain of the 2SD1486 will be in the range from 40 to 200, for the 2SD1486-P it will be in the range from 100 to 200, for the 2SD1486-Q it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SD1486-R might only be marked "D1486-R".The complementary PNP transistor to the 2SD1486-R is the 2SB1055-R.The BDP955 (SOT-223) is the SMD version of the 2SD1486-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1486-R with the 2SD1487, 2SD1487-R, 2SD1488 or 2SD1488-R.
