The BC414 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 collector, base, and emitter leads.
Here is an image showing the pin diagram of this transistor.The BC414 transistor can have a current gain of 180 to 800. The gain of the BC414B will be in the range from 180 to 460, for the BC414C it will be in the range from 380 to 800.The complementary PNP transistor to the BC414 is the BC416.The BC847 (SOT-23), BC847W (SOT-323), BC850 (SOT-23) and BC850W (SOT-323) is the SMD version of the BC414 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BC414 with the BC237, BC546, BC547 or BC550.
