The 2SC2274K-F 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 2SC2274K-F transistor can have a current gain of 160 to 320. The gain of the 2SC2274K will be in the range from 60 to 320, for the 2SC2274K-D it will be in the range from 60 to 120, for the 2SC2274K-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC2274K-F might only be marked "C2274K-F".The complementary PNP transistor to the 2SC2274K-F is the 2SA984K-F.The 2SC3438 (SOT-89) and 2SC3438-E (SOT-89) is the SMD version of the 2SC2274K-F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2274K-F with the 2SC1509, 2SC2383, 2SC2383-Y, 2SC3228, 2SC3228-Y, 2SC3332, 2SC3708, 2SC3939, 2SD1211, 2SD438, 2SD438-F, 2SD667, 2SD667D, KSC1009C, KSC2383, KSC2383Y, KTC1006, KTC3228, KTC3228Y or NTE382.
