The 031-326: This plug is specced for RG-55, RG-142, RG-223, and RG-400 cables — all 50 Ohm coax with a similar dielectric diameter and braid coverage. The contact termination accepts either crimp or solder, while the shield termination is crimp-only via the included ferrule. If your reel holds RG-58 or RG-174, the dielectric and jacket dimensions won't match the ferrule ID, so stick with the listed cable groups for a proper crimp.
