The 2SC1841E 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 2SC1841E transistor can have a current gain of 400 to 800. The gain of the 2SC1841 will be in the range from 200 to 1200, for the 2SC1841F it will be in the range from 300 to 600, for the 2SC1841P it will be in the range from 200 to 400, for the 2SC1841U it will be in the range from 600 to 1200.Sometimes the "2S" prefix is not marked on the package - the 2SC1841E might only be marked "C1841E".The 2SC1622A (SOT-23), FJV1845 (SOT-23) and FJV1845-E (SOT-23) is the SMD version of the 2SC1841E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1841E with the 2SC1775A, 2SC1775A-E, 2SC1845, 2SC1845E, 2SC1890A, 2SC1890A-E, 2SC2326K, 2SC2544, 2SC2544-E, 2SC2547, 2SC2547-E, 2SC2784, 2SC2784-E, 2SC3245, 2SC3245-G, 2SC3245A, 2SD756, 2SD756-E, KSC1845 or KSC1845E.
