Here is an image showing the pin diagram of this transistor.The 2SC3953-F transistor can have a current gain of 160 to 320. The gain of the 2SC3953 will be in the range from 40 to 320, for the 2SC3953-C it will be in the range from 40 to 80, for the 2SC3953-D it will be in the range from 60 to 120, for the 2SC3953-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC3953-F might only be marked "C3953-F".The complementary PNP transistor to the 2SC3953-F is the 2SA1538-F.You can replace the 2SC3953-F with the 2SC1565, 2SC1565A, 2SC1567A, 2SC2481, 2SC2481-Y, 2SC2690, 2SC2690-P, 2SC2690A, 2SC2690A-P, 2SC3116, 2SC3117, 2SC3598, 2SC3598-F, 2SC3599, 2SC3599-F, 2SC3902, 2SC3954, 2SC3954-F, 2SC3956, 2SC3956-F, 2SD600K, 2SD600K-F, 2SD669, 2SD669-D, KSC2690, KSC2690-Y, KSC2690A, KSC2690A-Y, KTC2803 or KTC2803-GR.
