The correct replacement pad for the AprilAire 500 / 550 / 558, and the sizes that look right but are not.
The AprilAire 500 / 550 / 558 takes the AprilAire 10 pad. Buy that part; a different-size pad lets water bypass into the plenum.

Fitment notes
The 500, 550 and 558 bypass humidifiers take the smaller Aprilaire 10 panel, not the 35. Fitting a 35 here leaves a gap the water runs straight through.
The panel for the 500 and 550 bypass humidifiers. It is close in size to the 35 but 3 inches shorter, so the two are not interchangeable even though both are Aprilaire.
