Looking for a 24 volt ,DPST relay with the same footprint as a Omron G5PZ-1A-EDC24. contact rating 8-20 amps
I am not seeing an item that would have the same footprint so far.
The below link shows the items that would otherwise match. A few I saw were close in size.
However, I would not be surprised if the addition of another whole switch in the device would prevent a 1:1 footprint match from being a thing.
