Searching for a replacement AC capacitor

[DMRF15]

I have an old Carrier RV AC on my pop-up with a discontinued SAMWHA capacitor. (picture attached.) I can't seem to find a replacement capacitor on-line anywhere, either from the US SAMWHA distributor, several on-line electronics supply stores, Carrier itself (they are out of the RV business it seems), a major RV dealership network, and a local HVAC electrician with links to the local distributors. Any ideas on how to find a compatible capacitor (12/40 microFarads; 370VAC?

you can substitute any cap. with at least that voltage and capacitance and larger. It won't hurt it to have a bit more. Limiting factor is where it's mounted but you can move it easily enough.

Grainger is a great source for items like this. A quick online search on their website will also tell you if a local branch near you has the item in stock.

that one will not work, as the OP's capacitor has 2 circuits in one can, a 40uf and a 10uf. its a start/run capacitor, not just a start cap.

Spoke with Grainger - as no one manufactures a single dual run with the correct farad ratings, they suggested using two - each with the correct microfarads - and splicing the commons together, which makes a lot of sense. I'll give it a try - the mounting should not bee too difficult as there is a lot of room in the compartment

This is a very common solution as the "one piece" units are required for applications where there is no extra space.

Bogieboy is correct. This is the direct replacement!

Buy Two!!

Thanks to all - I will try BogieBoy's direct replacement - I am assessing the slight difference in the fan motor's farad rating will not hinder operation. I wish I would have posted a few days ago - it would have saved me a lot of time and effort!

Guess you're right. He would have to use his finger to get the fan running. Incidentally, 370 volt rating is just the minimum; anything higher voltage rating is OK.
