Here is an image showing the pin diagram of this transistor.The 2SC3858-P transistor can have a current gain of 70 to 140. The gain of the 2SC3858 will be in the range from 50 to 180, for the 2SC3858-O it will be in the range from 50 to 100, for the 2SC3858-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC3858-P might only be marked "C3858-P".The complementary PNP transistor to the 2SC3858-P is the 2SA1494-P.You can replace the 2SC3858-P with the 2SC2774, 2SC2774-Y, 2SC3264 or 2SC3264-Y.
