Here is an image showing the pin diagram of this transistor.The 2SC1518-Q transistor can have a current gain of 90 to 155. The gain of the 2SC1518 will be in the range from 90 to 330, for the 2SC1518-R it will be in the range from 130 to 220, for the 2SC1518-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SC1518-Q might only be marked "C1518-Q".The 2SD874 (SOT-89), 2SD874-Q (SOT-89), BCP68 (SOT-223), BCP68-10 (SOT-223), BCX68 (SOT-89) and BCX68-10 (SOT-89) is the SMD version of the 2SC1518-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1518-Q with the 2SC1383, 2SC1383-Q, 2SC3940, 2SC3940-Q, 2SD468, 2SD468-B, 2SD471, 2SD471M, 2SD545, 2SD592, 2SD592-Q, 2SD592A, 2SD592A-Q, KTC3211 or KTC3211O.
