Parameter Comparison

Engineering Selection Recommendations

The substitute part Amphenol RF 112596 provides full electrical and mechanical compatibility with the 031-6004-RFX across all critical RF and connector parameters. Selection between these parts should be based on the following factors:

Product Status Consideration: The 031-6004-RFX carries "Not For New Designs" status, indicating manufacturer discontinuation of active development. The 112596 maintains "Active" product status, ensuring ongoing manufacturer support, availability, and compliance updates.

Compliance and Certification: Both parts maintain ROHS3 compliance and REACH affected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Packaging Configuration: The 031-6004-RFX is supplied in bulk packaging, while the 112596 is supplied in bag packaging. Packaging selection depends on inventory management requirements and application assembly processes.

Dielectric Material Difference: The 031-6004-RFX uses Polyoxymethylene (POM) Acetal dielectric material, while the 112596 uses Polytetrafluoroethylene (PTFE) dielectric material. Both materials support the specified electrical performance at 4 GHz and 50-ohm impedance. PTFE offers superior high-frequency performance and lower dielectric loss characteristics in extended frequency applications.

Frequently Asked Questions (FAQ)

Q: Can the 112596 directly replace the 031-6004-RFX in existing applications?

A: Yes. The 112596 matches all electrical parameters (50-ohm impedance, 4 GHz frequency, 0.2 dB insertion loss, 500 V rating) and mechanical parameters (BNC plug, male pin, right-angle solder termination, bayonet lock fastening) required for direct substitution. Both connectors are compatible with Belden 9913, 9914, and LMR-400 cable groups.

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

A: The 031-6004-RFX uses POM Acetal dielectric, while the 112596 uses PTFE dielectric. Both materials support the specified 4 GHz maximum frequency and 50-ohm impedance. PTFE provides lower dielectric loss and superior performance stability across temperature ranges, making it suitable for demanding RF applications. The choice between materials depends on specific application requirements beyond the stated 4 GHz specification.

Q: Why is the 031-6004-RFX marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product line. New designs should utilize the 112596, which maintains active product status and ensures access to current manufacturing processes, quality standards, and technical support.

Q: Are there packaging considerations when switching from 031-6004-RFX to 112596?

A: Yes. The 031-6004-RFX is supplied in bulk packaging, while the 112596 is supplied in bag packaging. This difference affects inventory management, component handling, and assembly line integration. Bulk packaging typically suits high-volume production, while bag packaging accommodates smaller lot sizes and modular inventory systems.

Q: Do both parts include the same accessories?

A: Yes. Both the 031-6004-RFX and 112596 include three pieces: one connector, one end cap, and one ferrule. This ensures equivalent assembly and installation procedures.

Q: What cable types are compatible with both connectors?

A: Both connectors are compatible with Belden 9913, 9914, and LMR-400 coaxial cable groups. These cables are standard in 50-ohm RF applications and support the specified frequency range up to 4 GHz.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 031-6004-RFX and 112596 maintain ROHS3 compliance and REACH affected status, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
