The connector is panel-mounted with a bulkhead rear-side nut and includes a lockwasher and nut in the package — three pieces total: connector, lockwasher, nut. The center contact is phosphor bronze with silver plating, terminated via solder cup. No official replacement part number is provided. Buyers should verify the mating half and panel cutout dimensions. ## What the 50 Ohm and 4 GHz Rating Mean for the Fit The 4 GHz maximum frequency covers the full L-band and S-band, including GPS (1.575 GHz), Wi-Fi 2.4 GHz, and most cellular bands below 4 GHz. Above 4 GHz the return loss degrades; for 6 GHz work (e.g., Wi-Fi 6E) a different BNC variant or an N-type connector is needed. The silver-plated center contact gives good conductivity and solderability but is softer than gold — limit mating cycles to the rated 500 to avoid wear on the center pin.","metaTitle":"TE Connectivity 227755-3 BNC Jack, 50 Ohm, 4 GHz, Bulkhead","metaDescription":"TE Connectivity 227755-3 BNC jack, 50 Ohm, 4 GHz, silver-plated contacts, panel mount with lockwasher and nut.
