The 2SC2631-T is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SC2631-T transistor can have a current gain of 360 to 700. The gain of the 2SC2631 will be in the range from 130 to 330, for the 2SC2631-R it will be in the range from 130 to 220, for the 2SC2631-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SC2631-T might only be marked "C2631-T".The KST2484 (SOT-23) is the SMD version of the 2SC2631-T transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2631-T with the 2SC1844, 2SC2396, 2SC2543, 2SC2545, 2SC2546, 2SC2634, 2SC2634-T, 2SC3329, 2SC3329-BL or KTC1006.
