The 2N3417 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 2SC3441 (SOT-23), 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23), 2SC3915 (SOT-23), FMMTA05 (SOT-23), KST05 (SOT-23), MMBTA05 (SOT-23), PZTA05 (SOT-223) and SMBTA05 (SOT-23) is the SMD version of the 2N3417 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N3417 with the 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD1207, 2SD1347, 2SD1616, 2SD1835, 2SD438, 2SD789, KSD1616, KTC1006 or NTE192A.
