Here is an image showing the pin diagram of this transistor.The MMBT918 (SOT-23) is the SMD version of the 2N706 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N706 with the 2N2220, 2N2221, 2N2222, 2N2369, 2N2369A, 2N706A, 2N706B, 2SC400, 2SC400-GR, 2SC400-O, 2SC400-Y, BC108, BC108A, BC108B, BC108C, BC109, BC109B, BC109C, BC378, BC378-6 or BC378-7.
