TE Connectivity 225395-1 BNC Plug — 50 Ohm, 4 GHz, RG-58 Crimp Termination
The kit includes the connector body, one gold-plated brass center contact, and one ferrule — everything needed for a single cable end. The bayonet lock provides a quick quarter-turn mate with 500-cycle durability, and the nickel-plated brass body gives it the standard silver appearance of a field-grade BNC.
The 50 Ohm characteristic impedance is maintained through the PTFE dielectric, and the connector is rated to 4 GHz with a typical insertion loss of 0.2 dB. The 500 V voltage rating covers the signal levels common in instrumentation and RF test setups. The cable group is RG-58 and its variants — the crimp ferrule and center contact are sized for that 0.195-inch diameter coax. For other cable types, the crimp dimensions will not match.
Obsolete — Sourcing Reality
No official replacement part number is recorded. For BOM lines that call out this exact order code, the only channel is surplus or broker inventory. If you are designing a new harness, consider a current-production BNC plug from the same TE family; the 225395-1 is best reserved for repair or replacement of an existing assembly.
What's in the Kit and How It Goes Together
The package is Bulk and includes three pieces: the BNC plug body with the PTFE insulator and gold-plated center contact pre-assembled, one loose center contact (a spare or for a different pin size — verify), and one crimp ferrule. The center contact is crimped onto the coax center conductor, the ferrule is crimped over the braid and jacket, and the plug body screws onto the ferrule. The bayonet lock mates with any standard BNC jack.
