The 2SC1845F 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 2SC1845F transistor can have a current gain of 300 to 600. The gain of the 2SC1845 will be in the range from 200 to 1200, for the 2SC1845E it will be in the range from 400 to 800, for the 2SC1845P it will be in the range from 200 to 400, for the 2SC1845U it will be in the range from 600 to 1200.Sometimes the "2S" prefix is not marked on the package - the 2SC1845F might only be marked "C1845F".The complementary PNP transistor to the 2SC1845F is the 2SA992F.The 2SC1622A (SOT-23), 2SC1622A-D17 (SOT-23), FJV1845 (SOT-23) and FJV1845-F (SOT-23) is the SMD version of the 2SC1845F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1845F with the 2SC1841, 2SC1841F, 2SC1890A, 2SC2240, 2SC2326K, 2SC2459, 2SC2544, 2SC2547, 2SC2784, 2SC2784-F, 2SC3200, 2SC3201, 2SC3245, 2SC3245A, 2SC3478, 2SC3478-U, 2SD756, KSC1845, KSC1845F or KTC3200.
