This is a standard 7-outlet battery-operated ignition module. It fits most grills that use that type of module. Unfortunately, I don't have data on the exact replacement for your model but most customers who purchase this part are buying it for their Nexgrills/Jennairs. Hope this helps!
Even though your model 720-0896 does not include any suffix letters, this is the correct ignition starter module for your grill. Usually the letters (B, C, E, etc) mean things like color or where it was sold and have nothing to do with the main parts of the grill.
