The TE Connectivity 9-328666-1 is a Coaxicon-series ferrule — a crimp-on metal sleeve that clamps over the braid or foil shield of a coaxial cable before the connector body is attached. The body is tin-plated copper alloy, silver in appearance, and the part comes in bulk packaging. It is designed for use with RG-174, RG-179A, RG-187, and RG-188 coaxial cables — the common 50- and 75-ohm small-diameter coax types used in video, RF, and instrumentation harnesses.
Cable Compatibility — What It Actually Fits
The ferrule is dimensioned for RG-174, RG-187, and RG-188 cables.
Lifecycle Reality — Obsolete and Sourced to Order
For a harness that already uses this part, the options are a last-time buy through surplus channels or a requalification to a current Coaxicon ferrule from the same series — the base product number 328666 family includes active variants that may cover the same cable diameters.
Sourcing This Ferrule Today
Because this ferrule is obsolete, standard distributor stock is depleted. The buyer should confirm the cable type (RG-174, 179A, 187, or 188) and the mating Coaxicon connector body before committing the BOM line. If a direct drop-in replacement is required, cross-referencing the base product number 328666 against current TE Connectivity Coaxicon ferrule listings is the next step.
