The Amphenol RF 31-70255 is a 75 Ohm mini BNC jack — the impedance that matters for composite video, CCTV, and 75 Ohm data links, not the 50 Ohm standard used in RF test benches.
It's a current catalog item from Amphenol RF.
Impedance (75 Ohm) is critical for matching in RF/video systems; mismatch causes signal loss.
Sourcing buyers need immediate stock and cost to fill BOM lines or repair orders.
Regulatory compliance is mandatory in many designs; failure to verify can halt production.
Lead time affects project planning and procurement schedules, especially for critical builds.
Engineers and brokers need alternatives for obsolete EOL or cost optimization without redesign.
Cable compatibility ensures proper fit and signal integrity; mismatches cause installation failures.
