My preference is to be able to find an exact replacement so I can use the same screw holes, but a "close enough" replacement is OK too.
Now sure what you mean you want the same screw holes to line up. A new window unit comes with no screw holes in it. The clamp ring has holes and they use self-drilling screws to mount the new window. The screw cut the new holes in the window unit as they are installed.
This link to a Lippert (LCI) window you posted has never been mounted. I can see the mounting holes in the window frame have never been installed.

That eBay listing calls out the trim ring (AKA clamp ring) to fit a 2" wall. Some sellers may not sell the trim ring with the window and your old one may not work with the new window pending brand and style. And, while you can buy the new window, it may be sold with the wrong trim ring to fit your wall. You have to watch out and verify.
