Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 1053786-1 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for adapter configuration, gender conversion, impedance, frequency rating, and operating temperature range. The critical substitution parameters are:

• Adapter Type: Plug to Jack configuration
• Conversion Type: Between Series (BNC to SMA)
• Center Gender: Female to Male
• Convert From: SMA Plug, Male Pin
• Convert To: BNC Jack, Female Socket
• Impedance: 50 Ohms
• Frequency - Max: 4 GHz
• Operating Temperature: -65°C ~ 125°C
• Fastening Type: Bayonet Lock, Threaded
• Material Composition: Brass, Stainless Steel body with Nickel, Passivated finish
• Center Contact: Beryllium Copper with Gold plating
• Dielectric: Polytetrafluoroethylene (PTFE)

The TE Connectivity 1058083-1 meets all these criteria and serves as a direct functional equivalent.
