I have a varistor that got blown from a rice cooker and i have acquired a new varistor though i am uncertain if it would be okay to use it. Would anyone be able to help?

As long as they are rated the same then it will be fine. Even in the factory they will switch component vendors to the one who is the cheapest per run as long as the spec is the same.

That i do understand, though the varistor in the 2 pictures that i added have 2 different markings on them.
@choukosenpai As long as the spec matches you’re good.

@choukosenpai here is the Panasonic Datasheet If you use that to check on the V10431 and the V7221 you will see that they are not compatible the V10431U is for twice the Amperage and Voltage then V7221. Since they are used as surge protectors, the difference in voltage and amperage will render that useless.
I am not sure which one the original from your rice cooker is but you now know what to look for in the datasheet to find a proper replacement. These components are really not to expensive and are usually readily available at places like mouser.com or digikey.com as well as many other places.
