The 2SC3331 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 2SC3331 transistor can have a current gain of 100 to 800. The gain of the 2SC3331-R will be in the range from 100 to 200, for the 2SC3331-S it will be in the range from 140 to 280, for the 2SC3331-T it will be in the range from 200 to 400, for the 2SC3331-U it will be in the range from 280 to 560, for the 2SC3331-V it will be in the range from 400 to 800.Sometimes the "2S" prefix is not marked on the package - the 2SC3331 might only be marked "C3331".The complementary PNP transistor to the 2SC3331 is the 2SA1318.You can replace the 2SC3331 with the 2SC3330, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD789 or KTC1006.
