"Napoleonic Era" includes the tail end of the Revolution and Napoleon as a whole.

"Revolutionary France" includes the Revolution and early stages of Napoleon.

There's enough overlap and short time frames in both regards that using either to date something wouldn't be blasphemous if it crawled into one or the other category a bit more than normal. And there's nothing wrong with applying both labels if something fits into both categories perfectly. "blah blah blah during Revolutionary and Napoleonic Era France.."
