replacement nut for a compression fitting on a 1/2 inch tube line, this the right part?

For a standard 1/2-inch compression-style tube fitting, this is the nut you'd be reaching for. It's made by Midland Industries specifically for that application, built to give you solid thread engagement and a leak-resistant connection at the fitting joint. As long as your existing setup uses a compression-style fitting in that size, it should drop right in as a replacement.
