75 Ohm BNC Adapter for Video and Telecom Signal Paths
The 1-1337492-0: It is a same-series conversion adapter, meaning it joins two BNC interfaces without changing the connector family. The 75 Ohm impedance and 1 GHz frequency ceiling place it in the video, broadcast, and telecom signal path — not the 50 Ohm world of general-purpose RF test gear.
Sourcing an Obsolete Part — What to Expect
If a direct replacement from TE or another manufacturer exists, it is not documented in the available records; verifying fit with the mating connector and the required impedance (75 Ohm) is the buyer's responsibility.
RF Performance and Mechanical Duty
The 1 GHz maximum frequency covers standard-definition and some high-definition video signals, but not multi-GHz serial digital interfaces. The 500 mating cycle rating is high for an adapter — it reflects the silver-plated centre contact and bayonet-lock fastening, which together resist fretting and maintain low intermodulation over repeated connects and disconnects in field-service or test-bench use.
