TE Connectivity 227079-9 BNC Plug, 50 Ohm, 4 GHz
It is a field-installable, crimp-terminated plug intended for use with the RG-58 cable group — RG-58, 58A, 58B, 58C, and 141. The 500 V voltage rating covers typical RF power levels in these bands. The connector ships as a 3-piece kit: the plug body, a gold-plated brass center contact, and a crimp ferrule.
The 227079-9 is specifically designed for the RG-58 cable family — RG-58, 58A, 58B, 58C, and 141 — all 50 Ohm, approximately 0.195-inch diameter coax with a solid or stranded center conductor.
We source this part through independent distribution channels against an RFQ. For a replacement recommendation, the closest parametric match is a standard 50 Ohm BNC plug for RG-58 cable from Amphenol RF or Cinch Connectivity, but pin-compatibility and form-fit-function must be verified against the specific application.
