Engineering Selection Recommendations

Primary Substitute: Amphenol RF 31-220N-RFX

The Amphenol RF 31-220N-RFX is the direct functional equivalent for the obsolete TE Connectivity 5228226-3. Both components share identical adapter configuration, impedance, mounting specifications, and contact materials. The substitute part offers the following advantages:

Product Status: The 31-220N-RFX maintains active product status with current manufacturing and supply availability, eliminating obsolescence risk.

Compliance: Both parts meet RoHS requirements. The Amphenol RF part carries ROHS3 compliance, representing current regulatory standards. Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.69.4010) codes.

Environmental Specifications: The 31-220N-RFX provides documented operating temperature range (-65°C ~ 165°C) and maximum frequency specification (4 GHz), parameters not specified for the original part.

Material Composition: The substitute uses brass body material versus zinc in the original, with polyoxymethylene acetal dielectric versus polyethylene. These material differences maintain electrical performance while potentially offering improved mechanical durability.

Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 31-220N-RFX directly replace the TE Connectivity 5228226-3 in existing applications?

A: Yes. Both connectors share identical functional specifications: BNC Jack-to-Jack female socket configuration, 50 ohm impedance, straight style, panel mount bulkhead design, and bayonet fastening. The mechanical and electrical interfaces are equivalent.

Q: What is the significance of the dielectric material difference between the two parts?

A: The original part uses polyethylene (PE) dielectric while the substitute uses polyoxymethylene (POM) acetal. Both materials are suitable for RF coaxial applications at 50 ohms. The material change does not affect electrical compatibility or impedance matching in this adapter application.

Q: Why does the Amphenol RF part specify operating temperature and frequency limits while the original does not?

A: The original TE Connectivity part is obsolete and lacks current specification documentation. The Amphenol RF 31-220N-RFX provides complete technical specifications including operating temperature range (-65°C ~ 165°C) and maximum frequency (4 GHz). These specifications define the operational envelope for the substitute part.

Q: Are there packaging differences between the two parts?

A: The TE Connectivity 5228226-3 packaging is not specified in available documentation. The Amphenol RF 31-220N-RFX is supplied in bulk packaging. Both parts include identical component sets: 1 connector, 1 lockwasher, and 1 nut.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are RoHS compliant. The Amphenol RF part carries ROHS3 compliance, representing current regulatory standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications for export and tariff purposes.

Q: What is the moisture sensitivity classification for these connectors?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Are the contact materials identical between the two parts?

A: Yes. Both connectors feature gold-plated center contacts with phosphor bronze base material. This ensures equivalent electrical performance and contact reliability.
