No, all i5 sockets carry over from manufacturer to manufacturer, but different generations have different sockets, e.g. an i5 3570 uses socket 1155, while an i5 4670 uses the 1150. Some laptops have socketed CPUs, but others are soldered on the motherboard. I would recommend looking at a disassembly video for your particular system, or read the service manual. Weather or not the MB is worth salvaging depends on the year of the computer, and what you plan to do with it.
