Here is an image showing the pin diagram of this transistor.The 2SC1518 transistor can have a current gain of 90 to 330. The gain of the 2SC1518-Q will be in the range from 90 to 155, 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 might only be marked "C1518".The 2SD874 (SOT-89), BCP68 (SOT-223) and BCX68 (SOT-89) is the SMD version of the 2SC1518 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1518 with the 2SC1383, 2SC3940, 2SD471, 2SD545, 2SD592 or 2SD592A.
