BNC Bulkhead Jack Kit — What You Get and Where It Fits
The 5225398-8: The kit is packaged in Bulk, so you get everything needed for one termination in a single order code. This BNC jack is built for RG-179 and RG-187 coaxial cables — the 75 Ohm miniature coax types commonly used in video, broadcast, and instrumentation.
Obsolete — Sourcing Reality for the 5225398-8
The 5225398-8 is officially listed as Obsolete. TE Connectivity no longer manufactures this BNC jack kit as a standard production item. For a buyer with a BOM line calling out this exact order code, the sourcing path is through independent distribution and surplus inventory.
What the Kit Includes — No Surprises at the Bench
The 7-piece kit breaks down as: 1 BNC jack connector body (with PTFE insulator and gold-plated beryllium copper center contact installed), 1 bushing, 1 center contact (spare or for field replacement), 1 crimp ferrule, 1 gasket, 1 lockwasher, and 1 mounting nut. The nut secures the connector from the front side of the panel — a bulkhead front-side nut mount. The gasket provides a seal against the panel face.
Cable Prep and Termination Notes
This jack is designed for RG-179 and RG-187 cables. Both cable types are 75 Ohm miniature coax with a solid or stranded center conductor and a braided shield. The center contact crimps onto the center conductor; the ferrule crimps over the braid and jacket. Strip lengths and crimp die selection follow the manufacturer's application tooling recommendations for these cable groups. The PTFE dielectric handles the 500 V rating and 4 GHz bandwidth without signal degradation.
