Amphenol RF 000-79125 TNC Coaxial Connector Adapter Equivalent & Substitute Parts

Part Overview

The Amphenol RF 000-79125 is an active TNC coaxial connector adapter designed to convert between TNC Jack (female socket) and TNC Plug (male pin) configurations. This right-angle, threaded adapter operates at 50 Ohms impedance and supports frequencies up to 11 GHz. The adapter is manufactured from brass with nickel finish and beryllium copper center contacts, rated for 500 mating cycles across an operating temperature range of -40°C to 85°C. Equivalent substitute parts are identified based on matching electrical specifications, mechanical compatibility, and connector conversion functionality within the TNC series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 000-79125 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters:

Critical Matching Parameters:

• Adapter Series: TNC to TNC (same series conversion)
• Center Gender Configuration: Female to Male (identical gender conversion)
• Impedance: 50 Ohms (electrical compatibility)
• Style: Right Angle (mechanical form factor)
• Mounting Type: Free Hanging (In-Line), Right Angle (installation compatibility)
• Fastening Type: Threaded, Threaded (connection method)
• Dielectric Material: Polytetrafluoroethylene (PTFE) (signal integrity)
• Body Material: Brass (structural compatibility)
• Body Finish: Nickel (environmental protection)
• Mating Cycles: 500 (durability specification)

The Pomona Electronics 73053 meets all critical matching parameters and qualifies as a functional equivalent substitute for the Amphenol RF 000-79125 within TNC coaxial connector adapter applications.

Engineering Selection Recommendations

Amphenol RF 000-79125 is the primary specification component. This part is active, ROHS3 compliant, and REACH affected. It provides maximum frequency capability of 11 GHz with silver-plated beryllium copper center contacts, supporting high-frequency RF applications requiring extended bandwidth.

Pomona Electronics 73053 is a functional equivalent substitute. This part is active and ROHS3 compliant but REACH unaffected. The substitute operates at a maximum frequency of 4 GHz, which limits its application to lower-frequency RF systems. The gold-plated brass and phosphor bronze center contacts provide alternative contact material specifications.

Selection between these parts depends on application frequency requirements. The Amphenol RF 000-79125 is specified for systems requiring operation up to 11 GHz. The Pomona Electronics 73053 is suitable for applications operating at frequencies up to 4 GHz. Both parts share identical mechanical form factors, mounting configurations, impedance specifications, and mating cycle ratings, ensuring mechanical and electrical interchangeability within their respective frequency operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 73053 be used as a direct replacement for the Amphenol RF 000-79125?

A: The Pomona Electronics 73053 is mechanically and electrically compatible with the Amphenol RF 000-79125 for TNC coaxial connector adapter applications. However, the frequency maximum specification differs: the Pomona part operates to 4 GHz while the Amphenol part operates to 11 GHz. Substitution is valid only for applications operating within the 4 GHz frequency limit.

Q: What are the key compatibility criteria for TNC adapter substitution?

A: Critical compatibility parameters include adapter series (TNC to TNC), center gender configuration (female to male), impedance (50 Ohms), style (right angle), mounting type (free hanging in-line right angle), fastening type (threaded), dielectric material (PTFE), body material (brass), body finish (nickel), and mating cycle rating (500). Both parts match all these parameters.

Q: How do the center contact materials differ between these parts?

A: The Amphenol RF 000-79125 uses beryllium copper center contacts with silver plating. The Pomona Electronics 73053 uses brass and phosphor bronze center contacts with gold plating. Both configurations provide electrical conductivity and environmental protection appropriate for 50 Ohm RF applications within their respective frequency ranges.

Q: Are both parts RoHS compliant?

A: Yes, both the Amphenol RF 000-79125 and Pomona Electronics 73053 are ROHS3 compliant. The Amphenol part is REACH affected, while the Pomona part is REACH unaffected.

Q: What is the operating temperature range for these adapters?

A: The Amphenol RF 000-79125 operates across -40°C to 85°C. Operating temperature range data is not provided for the Pomona Electronics 73053.

Q: How many mating cycles are rated for these connectors?

A: Both the Amphenol RF 000-79125 and Pomona Electronics 73053 are rated for 500 mating cycles, indicating equivalent durability and mechanical reliability for connector engagement and disengagement operations.
