Here is an image showing the pin diagram of this transistor.The 2SD602A-R transistor can have a current gain of 120 to 240. The gain of the 2SD602A will be in the range from 85 to 340, for the 2SD602A-Q it will be in the range from 85 to 170, for the 2SD602A-S it will be in the range from 170 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SD602A-R might only be marked "D602A-R".The complementary PNP transistor to the 2SD602A-R is the 2SB710A-R.You can replace the 2SD602A-R with the 2SC3325, 2SC3325-Y, 2SC3912, 2SC3913, 2SC3914, 2SC3915, FMMT491, FMMT491Q, FMMT619, FMMT620, FMMTA05, FMMTA06, KST05, KST06, MMBTA05, MMBTA06, PMBTA06, SMBTA05 or SMBTA06.
