Probably not. The entire XTL series' biggest failing is the unserviceable uniboard. They would replace the entire thing if anything goes wrong with it, it's cheap for them to do at the factory but it makes for a radio that is entirely unfixable in the field. You might find a similar conector in the SM50/SM120 series if it's a right-angle type, perhaps? It may be a commonly available part, but there may be no "outside" (order-able) part number for it. You'll probably have to scrounge for it. If you're really lucky, it may have the OEM's markings on it (like Cinch-Jones or Amphenol, etc.) and if you're extremely lucky, it might even have their common part number on it.
