HDCI Cables for HDX Camera

I have purchased a few second hand HDX 6000's that included the unit, camera and mic but no cables.

Checking the integration manual:

and there is also Real Presence Group manual which list two SKUs rather than one for the cable.

Length Part Number RoHS Compliant
9 ft 10 in (3 m) 2457-23180-003 Yes
9 ft 10 in (3 m) 2457-65015-003 Yes

Can I use either a 2457-23180-003 or 2457-65015-003 on a HDX 6000 or 7000 to connect an Eagle Eye camera to the unit?

And for the Microphone a similar story I can use any of the SKUs from the RPG manual rather than the HDX manual as they need the Walta connectors.

Length Part Number RoHS Compliant

It looks like ebay is the best place to pickup second hand ones or is there somewhere I can pick up replacement cables at a reasonable price that post internationally?
