Hello Nasomi You won't know for sure unless you try one out. I doubt they will be cross-compatible. If you look at the rack installation guides for the two servers there are illustrations of the cable management arms. They appear to have different connectors where they attach to the rail system.

A guy has 30pc of these arms for sale locally, and I have 1950's, so I was hoping they might be similar enough to be interchangable.
PE1750 Cable management arms on PE1950?
