Note 4 repair help please ( POWER Button issue )

So out of nowhere my power button stopped working. I cant turn the phone off or on or lock the screen when its awake. I called a few places but none seem to be able to fix it. So looks like i may have to give this a shot myself.

Did some research and came up with this hardware.....

Can anyone tell me if this is the correct part needed? I can feel my current bitton click bit it just wont respond. I just wanna make sure this is the correct part as another squarish hardware button came?up in my search for a replacement.

Thanks in advance.
