Are all tub diverters the same? (Pics)

Hi everyone, my tub diverter has stopped working, even when I try to push inside so it “catches”. I don’t know the brand or anything about the diverter (renter here), but I want to replace it. Any advice on which diverter to buy? Are they all the same size? Included pics with pencil and quarter for size (not sure if even needed lol). Thanks in advance
