Pella Slider Handle

Most Pella doors cannot use non-Pella brand products at all, in my experience, and the 82-086 is definitely not a Pella-brand product. However there are a few uncommon exceptions that come to mind.

Instead of guessing, though, it would be best if you show me photos of your original handle set so that I have a better idea of what you're working with. I will then be in a much better position to confirm whether or not the 82-086 is a feasible replacement option.
