The 2SC2634-R 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 2SC2634-R transistor can have a current gain of 180 to 360. The gain of the 2SC2634 will be in the range from 180 to 700, for the 2SC2634-S it will be in the range from 260 to 520, for the 2SC2634-T it will be in the range from 360 to 700.Sometimes the "2S" prefix is not marked on the package - the 2SC2634-R might only be marked "C2634-R".The complementary PNP transistor to the 2SC2634-R is the 2SA1127-R.The MMBT2484 (SOT-23) is the SMD version of the 2SC2634-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2634-R with the 2SC2002, 2SC2003, 2SC3708, 2SD1616A, 2SD438, KSC1008C, KSD1616A or KTC1006.
