Here is an image showing the pin diagram of this transistor.The 2SC3907-O transistor can have a current gain of 90 to 180. The gain of the 2SC3907 will be in the range from 55 to 180, for the 2SC3907-R it will be in the range from 55 to 110.Sometimes the "2S" prefix is not marked on the package - the 2SC3907-O might only be marked "C3907-O".The complementary PNP transistor to the 2SC3907-O is the 2SA1516-O.You can replace the 2SC3907-O with the 2SC3519A, 2SC3519A-O, 2SC3519A-P, 2SC3519A-Y, 2SC3856, 2SC3856-Y, 2SC6011, 2SC6011-Y, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, 2SD1313, 2SD1718, MJL4281A, MJL4281AG, MJW3281A or MJW3281AG.
