Parameter Comparison

Engineering Selection Recommendations

The Amphenol RF 31-218 is the qualified substitute for the obsolete TE Connectivity AMP Connectors 1-1337455-0. Selection of the 31-218 is supported by the following factors:

Product Status: The 31-218 maintains active product status, ensuring ongoing availability and supply chain continuity. The 1-1337455-0 is obsolete and subject to inventory depletion.

Compliance Certifications: Both parts maintain equivalent compliance profiles. The 1-1337455-0 is RoHS Compliant, while the 31-218 is ROHS3 Compliant, representing an advancement in regulatory compliance. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Functional Equivalence: All critical electrical and mechanical parameters match between the two parts, including impedance, frequency rating, operating temperature range, and connector geometry.

Material Composition: The primary difference is body finish specification. The 1-1337455-0 features silver body finish, while the 31-218 features nickel body finish. Both finishes are compatible with the silver-plated center contacts and PTFE dielectric material.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 31-218 directly replace the TE Connectivity 1-1337455-0 in existing RF systems?

A: Yes. The 31-218 meets all mandatory electrical and mechanical parameters required for direct substitution, including 50 ohm impedance, BNC plug-to-plug configuration, male-to-male center gender, 4 GHz frequency rating, and identical operating temperature range.

Q: What is the significance of the body finish difference between silver and nickel?
