The KSC1845E 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 KSC1845E transistor can have a current gain of 400 to 800. The gain of the KSC1845 will be in the range from 200 to 1200, for the KSC1845F it will be in the range from 300 to 600, for the KSC1845P it will be in the range from 200 to 400, for the KSC1845U it will be in the range from 600 to 1200.The complementary PNP transistor to the KSC1845E is the KSA992E.The 2SC1622A (SOT-23), FJV1845 (SOT-23) and FJV1845-E (SOT-23) is the SMD version of the KSC1845E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC1845E with the 2SC1775A, 2SC1775A-E, 2SC1841, 2SC1841E, 2SC1845, 2SC1845E, 2SC1890A, 2SC1890A-E, 2SC2326K, 2SC2544, 2SC2544-E, 2SC2547, 2SC2547-E, 2SC2784, 2SC2784-E, 2SC3245, 2SC3245-G, 2SC3245A, 2SD756 or 2SD756-E.
