The 2SC2003-L 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-L transistor can have a current gain of 135 to 270. 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-M it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC2003-L might only be marked "C2003-L".The complementary PNP transistor to the 2SC2003-L is the 2SA954-L.You can replace the 2SC2003-L with the 2SC1509, 2SC2274K, 2SC2383, 2SC3228, 2SC3244, 2SC3332, 2SC3708, 2SC3939, 2SD1211, 2SD438, 2SD667, KSC1009C, KSC2383, KSP8099C, KTC1006 or KTC3228.
