Engineering Selection Recommendations

Primary Substitute: Amphenol RF 122116

The 122116 is the qualified equivalent for CTNC174 replacement applications. Selection rationale:

• Product Status: The 122116 is active production, ensuring long-term availability and supply chain reliability compared to the obsolete CTNC174.
• Compliance: Both parts share identical ECCN (EAR99) and HTSUS classifications, maintaining regulatory consistency.
• Regulatory Certifications: The 122116 carries RoHS3 compliance and REACH affected status, meeting current environmental standards.
• Functional Compatibility: Identical connector style, type, termination method, and fastening mechanism ensure direct mechanical and electrical compatibility.
• Cable Compatibility: The 122116 supports RG-174 cable group plus additional cable types, providing expanded application flexibility.

The substitute part is suitable for direct replacement in applications originally specified for CTNC174 TNC plug connectors with RG-174 cable termination.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 122116 directly replace the TE Connectivity Laird CTNC174?

A: Yes. Both connectors share identical connector style (TNC), type (Plug, Male Pin), termination method (Crimp), and fastening type (Threaded). The 122116 is mechanically and electrically compatible for CTNC174 applications.

Q: What cable types are compatible with the 122116 substitute?

A: The 122116 supports RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 cable groups. The original CTNC174 specification references RG-174, which is fully supported by the substitute.

Q: Are there compliance or regulatory differences between the two parts?

A: No. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications. The 122116 additionally carries RoHS3 compliance and REACH affected status, meeting current environmental requirements.

Q: What is the packaging format for the substitute part?

A: The 122116 is supplied in bag packaging. Each connector includes 5 pieces: 1 connector, 1 contact, 1 ferrule, 1 insulator, and 1 sleeve.

Q: Does the substitute part have different electrical specifications?

A: The 122116 provides additional electrical specifications not listed for the CTNC174: 50 Ohm impedance, 11 GHz maximum frequency, 500 V voltage rating, 500 mating cycles, and 0.18 dB insertion loss. These specifications define the substitute's performance envelope.

Q: Is the moisture sensitivity level the same?

A: Yes. Both the CTNC174 and 122116 have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
