Here is an image showing the pin diagram of this transistor.The KSC2330 transistor can have a current gain of 40 to 240. The gain of the KSC2330O will be in the range from 70 to 140, for the KSC2330R it will be in the range from 40 to 80, for the KSC2330Y it will be in the range from 120 to 240.The PMBTA42 (SOT-23) is the SMD version of the KSC2330 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC2330 with the 2SC3468 or KSC1506.
