Hey Matt, thanks for the picture and information! To replace your Dometic DuoTherm 641915c851c0 Penguin II ac unit you'll need to replace the entire system. None of the newer units are compatible with the older Dometic air boxes because all of the old R410A units and their parts are being phased out. Not only will this allow you to avoid any compatibility issues, it will allow you to upgrade to an AC unit with the new R32 refrigerant.
Additionally, if you find a replacement that has the same connector the pin functions are most likely going to be different and you'll void the warranty on your brand new AC unit.
For a replacement system, I recommend the Advent Air RV Air Conditioner System item # ADV95SR in white or item # ADV52SR. These are comparable 13,500 btu systems that include an air box, AC unit, start capacitor, and a thermostat. They are single zone systems that work with both ducted and ductless set ups.
What kind of RV or trailer do you have?
