Engineering Selection Recommendations

Primary Recommendation for Active Designs:

The 31-10-RFX (Amphenol RF) and 1-1337452-0 (TE Connectivity AMP Connectors) are the preferred substitutes for new designs. Both parts maintain active product status, provide ROHS3 compliance, and deliver full electrical and mechanical compatibility with the 227726-3 specification. The 31-10-RFX offers extended operating temperature range (-65°C to 165°C) matching the original part, while the 1-1337452-0 provides documented insertion loss specification (0.2 dB).

Secondary Recommendation for Legacy System Maintenance:

The 5227726-3 (TE Connectivity AMP Connectors) provides direct manufacturer continuity with active product status. This part is electrically and mechanically identical to the 227726-3 but carries RoHS non-compliant status. Selection of this part is appropriate for systems where RoHS compliance is not a regulatory requirement.

Alternative Recommendations:

The 31-10 (Amphenol RF) and 1-1337447-0 (TE Connectivity AMP Connectors) are functionally equivalent alternatives with active product status and full RoHS compliance. The 031-10-1002 (Amphenol RF) provides cross-manufacturer compatibility with active status and ROHS3 compliance.

Obsolete Part Consideration:

The 5-1634504-1 (TE Connectivity AMP Connectors) is classified as obsolete and should not be selected for new designs. This part is retained in the substitute list only for reference in legacy system documentation.

Frequently Asked Questions (FAQ)

Q: Can the 227726-3 be directly replaced with the 5227726-3?

A: Yes. The 5227726-3 maintains identical electrical and mechanical specifications to the 227726-3. The primary difference is product status (active versus obsolete) and RoHS compliance classification. The 5227726-3 is electrically and mechanically interchangeable for all applications where the 227726-3 was originally specified.

Q: What is the difference between the 31-10 and 31-10-RFX?

A: Both parts are manufactured by Amphenol RF and maintain identical electrical and mechanical specifications. The primary difference is operating temperature range: the 31-10 operates from -55°C to 85°C, while the 31-10-RFX extends to -65°C to 165°C. Selection between these parts depends on the thermal requirements of the application.

Q: Are all substitute parts RoHS compliant?

A: No. The 5227726-3 is classified as RoHS non-compliant. All other substitute parts listed (31-10, 31-10-RFX, 1-1337447-0, 1-1337452-0, 031-10-1002, and 5148) are RoHS3 compliant or RoHS compliant. Regulatory requirements for the target application determine whether RoHS compliance is mandatory.

Q: What packaging options are available for substitute parts?

A: Packaging varies by part number. The 5227726-3 is supplied in tray packaging. The 1-1337447-0 and 1-1337452-0 are supplied in bulk packaging. The 31-10 and 31-10-RFX are supplied in bulk packaging. The 031-10-1002 packaging is not specified. The 5148 is supplied in bulk packaging. Verify packaging requirements with procurement specifications before part selection.

Q: Can the 227726-3 be used in applications requiring insertion loss specification?

A: The 227726-3 does not provide documented insertion loss specification. For applications requiring insertion loss data, the 31-10-RFX, 31-10, 1-1337452-0, and 031-10-1002 all provide 0.2 dB insertion loss specification.

Q: Are there frequency rating differences between substitute parts?

A: The 227726-3 and most substitute parts are rated to 4 GHz maximum frequency. The 031-10-1002 does not specify frequency rating in the provided data. For applications requiring confirmed 4 GHz operation, select parts with explicit 4 GHz frequency specification.

Q: What is the difference between TE Connectivity and Amphenol RF substitute options?

A: Both manufacturers provide functionally equivalent BNC connectors meeting the 227726-3 specification. TE Connectivity options (5227726-3, 1-1337447-0, 1-1337452-0) maintain direct manufacturer continuity. Amphenol RF options (31-10, 31-10-RFX, 031-10-1002) provide cross-manufacturer alternatives. Selection between manufacturers depends on supply chain, qualification requirements, and procurement preferences.

Q: Is the Pomona Electronics 5148 a suitable substitute?

A: Yes. The 5148 maintains electrical and mechanical compatibility with the 227726-3, including 50 ohms impedance, BNC connector style, female socket configuration, solder cup termination, panel mount bulkhead mounting, and bayonet lock fastening. The 5148 is active product status and ROHS3 compliant. Mating cycle specification is not provided for this part.
