Here is an image showing the pin diagram of this transistor.The KSC2331Y transistor can have a current gain of 120 to 240. The gain of the KSC2331 will be in the range from 40 to 240, for the KSC2331O it will be in the range from 70 to 140, for the KSC2331R it will be in the range from 40 to 80.The complementary PNP transistor to the KSC2331Y is the KSA931Y.The BCV71 (SOT-23) is the SMD version of the KSC2331Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC2331Y with the 2SC2235, 2SC2235-Y, 2SC3243, 2SC3328, 2SC3328-Y, 2SD438, 2SD667, KSC1008C, KSC1008CY, KSC2316, KSC2316Y, KTC1006, KTC1008, KTC1027, KTC1027-O or KTC1027-Y.
