Is iPhone 5s power button flex cable interchangabe with SE?

Have an SE with a slight cracked housing on the right side of the volume down button, with a minuscule bend to the housing that runs perpendicularly the other side. Initially phone was dropped which broke the screen and left that crack to the housing. Had screen replaced with an SE screen. All was working. Over time the power button and hold stopped working. Have a spare 5s A 1533 phone, interchangeable with my SE? bonus question; is the damaged housing causing this?
