You may be able to reuse the cracked cap if it can be successfully assembled.
A second hand cap may have wear or machining differences that cause a poor fit between the used cap and your camshaft. Worth a try anyhow and what I would try first.

The reason for this is that the caps are machined to the cylinder head. The head and the cap are the bearing surface. You can't just go slapping a new cap on this head and expect things to work properly.
They are a matched set. You're on the right track.
