The 2SC2003-M 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 2SC2003-M transistor can have a current gain of 90 to 180. The gain of the 2SC2003 will be in the range from 90 to 400, for the 2SC2003-K it will be in the range from 200 to 400, for the 2SC2003-L it will be in the range from 135 to 270.Sometimes the "2S" prefix is not marked on the package - the 2SC2003-M might only be marked "C2003-M".The complementary PNP transistor to the 2SC2003-M is the 2SA954-M.The 2SC4209 (SOT-23) is the SMD version of the 2SC2003-M transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2003-M with the 2N5551C, 2SC1627, 2SC1627A, 2SC2235, 2SC2274K, 2SC2383, 2SC3228, 2SC3244, 2SC3244-D, 2SC3328, 2SD438, 2SD667, 2SD667A, KSC1009C, KSC2316, KSC2383, KTC1027, KTC1027-O, KTC1027-Y, KTC3227 or KTC3228.
