TNC Connector Jack 50 Ohm Solder (Amphenol RF 122423)

Part Overview

The Amphenol RF 122423 is a TNC connector jack with female socket configuration, designed for 50-ohm coaxial cable applications. This free-hanging, in-line solder connector operates at frequencies up to 11 GHz and is suitable for RF/microwave signal transmission in aerospace, defense, and industrial applications. The part is currently active in production with 857 units in stock. Alternative equivalent parts may be required due to supply constraints, application-specific mounting requirements, or design modifications necessitating panel-mount configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 122423 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector Style: TNC (threaded coupling interface)
• Connector Type: Female Socket (jack configuration)
• Impedance: 50 Ohms (signal integrity requirement)
• Contact Termination: Solder (assembly method compatibility)
• Shield Termination: Solder (assembly method compatibility)
• Fastening Type: Threaded (mechanical interface)

Secondary Compatibility Criteria:

• Frequency Rating: Minimum 11 GHz
• Voltage Rating: Minimum 500 V
• Mating Cycles: Minimum 500
• Dielectric Material: PTFE (electrical performance)
• Body Material: Brass with Nickel finish
• Center Contact Plating: Gold

Application-Dependent Criteria:

• Mounting Type: Free Hanging (In-Line) versus Panel Mount (determines physical installation method)

The TE Connectivity Aerospace, Defense and Marine part 1057775-1 qualifies as an equivalent substitute based on matching primary compatibility criteria. However, this part features Panel Mount configuration with flange, which represents a functional difference in mounting methodology rather than electrical incompatibility.

Engineering Selection Recommendations

Primary Selection: Amphenol RF 122423

The Amphenol RF 122423 remains the preferred component for new designs and production applications. This part is currently active in production with adequate inventory (857 units in stock), ensuring supply chain reliability. ROHS3 compliance and REACH affected status align with current regulatory requirements for aerospace, defense, and industrial markets.

Substitute Selection: TE Connectivity Aerospace, Defense and Marine 1057775-1

The TE Connectivity 1057775-1 is electrically and mechanically equivalent for RF signal transmission applications requiring 50-ohm TNC female socket connectors. This part maintains identical impedance, frequency capability, voltage rating, and mating cycle specifications. Both parts utilize PTFE dielectric material and gold-plated center contacts, ensuring equivalent signal integrity and reliability.

Critical Consideration: The TE Connectivity part is discontinued at DiGi Electronics and features Panel Mount configuration with flange, whereas the Amphenol part is free-hanging in-line. This mounting difference requires circuit board or enclosure design modification. Selection of the TE Connectivity substitute is appropriate only when panel-mount installation is required and design modification is feasible.

Both parts carry identical compliance certifications (ROHS3, REACH affected, EAR99 ECCN, HTSUS 8536.69.4010), supporting use in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1057775-1 be used as a direct replacement for the Amphenol RF 122423 in existing assemblies?

A: Electrical substitution is valid. Both connectors maintain 50-ohm impedance, identical frequency rating (11 GHz), and equivalent solder termination methods. However, the mounting configuration differs: the Amphenol part is free-hanging in-line, while the TE Connectivity part is panel-mount with flange. Direct physical substitution requires circuit board or enclosure modification to accommodate the flange-mount interface.

Q: What are the key electrical parameters that must match for TNC connector substitution?

A: Critical matching parameters are connector style (TNC), connector type (female socket/jack), impedance (50 ohms), contact termination method (solder), shield termination method (solder), and fastening type (threaded). Frequency rating must meet or exceed 11 GHz. Voltage rating must meet or exceed 500 V. Mating cycle rating must meet or exceed 500 cycles.

Q: Are there frequency limitations when substituting these connectors?

A: Both the Amphenol RF 122423 and TE Connectivity 1057775-1 are rated to 11 GHz maximum frequency. Substitution is valid for applications operating at or below this frequency. Applications requiring higher frequency operation require alternative connector families.

Q: What is the significance of the solder cup termination on the TE Connectivity part versus standard solder termination?

A: Both termination methods are solder-based and compatible with wave soldering and hand soldering assembly processes. Solder cup design provides a defined solder reservoir, which may improve solder joint consistency in high-volume manufacturing. Electrical performance and reliability are equivalent.

Q: Are both parts suitable for aerospace and defense applications?

A: Both parts carry ROHS3 compliance and REACH affected status. The TE Connectivity part is manufactured by TE Connectivity Aerospace, Defense and Marine division, indicating aerospace/defense qualification. The Amphenol RF part is suitable for these applications. Specific qualification requirements should be verified against applicable procurement specifications (MIL-DTL, AS, or customer-specific standards).

Q: What is the inventory status difference between these parts?

A: The Amphenol RF 122423 has 857 units in stock and active production status. The TE Connectivity 1057775-1 has 702 units in stock but is discontinued at DiGi Electronics. For new production programs, the Amphenol part offers superior supply chain continuity.
