The 031-80102: This connector is a 3-piece kit: the BNC plug body, the center contact, and the ferrule. The listed cable group covers 75 Ohm video and broadcast coax — RG-59 is not in the group, so verify the cable outer diameter and dielectric fit against the connector dimensions before committing to a build.
The 031-80102 carries a Not Recommended for New Design (NRND) status. That means Amphenol still supports existing designs but has flagged it for eventual phase-out — new projects should look at the current 75 Ohm BNC offering from the same series.
