The 2SC1775A-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 2SC1775A-F transistor can have a current gain of 600 to 1200. The gain of the 2SC1775A will be in the range from 400 to 1200, for the 2SC1775A-E it will be in the range from 400 to 800.Sometimes the "2S" prefix is not marked on the package - the 2SC1775A-F might only be marked "C1775A-F".The FJV1845 (SOT-23) and FJV1845-U (SOT-23) is the SMD version of the 2SC1775A-F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1775A-F with the 2SC1841, 2SC1841U, 2SC1845, 2SC1845U, 2SC1890A, 2SC1890A-F, 2SC2544, 2SC2784, 2SC2784-U, KSC1845 or KSC1845U.
