Here is an image showing the pin diagram of this transistor.The 2SC1848-Q transistor can have a current gain of 80 to 160. The gain of the 2SC1848 will be in the range from 50 to 220, for the 2SC1848-P it will be in the range from 50 to 100, for the 2SC1848-R it will be in the range from 120 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SC1848-Q might only be marked "C1848-Q".The complementary PNP transistor to the 2SC1848-Q is the 2SA887-Q.The FMMT451 (SOT-23) is the SMD version of the 2SC1848-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1848-Q with the 2SC1098A or 2SC1098A-L.
