Parameter Comparison

Engineering Selection Recommendations

For Legacy System Maintenance: The 031-2300-RFX remains suitable for repair and maintenance of existing installations where the "Not For New Designs" status does not present a constraint. Current inventory of 1,072 pieces supports ongoing field service requirements.

For New Product Development: The substitute part 122248 is the appropriate selection for new designs. This part carries Active product status, ensuring continued manufacturing support, technical documentation availability, and supply chain stability. The 122248 offers enhanced material specifications with nickel body finish and gold center contact plating, providing improved corrosion resistance and contact reliability compared to the legacy 031-2300-RFX.

Compliance Considerations: Both parts maintain ROHS3 compliance and REACH affected status, satisfying regulatory requirements for EU and international markets. The EAR99 export classification applies to both variants, with identical HTSUS commodity codes confirming functional equivalence.

Material Upgrade Path: The transition from silver to gold center contact plating in the 122248 represents a material enhancement that improves long-term contact performance and oxidation resistance without altering electrical specifications. The nickel body finish provides superior environmental protection in applications subject to corrosive atmospheres.

Frequently Asked Questions (FAQ)

Q: Can the 122248 directly replace the 031-2300-RFX in existing assemblies?

A: Yes. The 122248 maintains identical electrical and mechanical specifications across all critical parameters including impedance, frequency response, insertion loss, and mating cycle rating. The connector style, receptacle configuration, solder cup termination, and panel mount flange are functionally equivalent. The packaging difference (Bag versus Bulk) does not affect component performance.

Q: What is the significance of the product status change from "Not For New Designs" to "Active"?

A: The "Not For New Designs" designation on the 031-2300-RFX indicates that Amphenol RF has concluded active development and optimization of this part. The Active status of the 122248 confirms ongoing manufacturing, quality assurance, and technical support. For new product development, the Active status ensures long-term component availability and supplier commitment.

Q: Are there electrical performance differences between the two parts?

A: No. Both parts deliver identical electrical performance with 0.18 dB insertion loss, 11 GHz maximum frequency, 500 V voltage rating, and 500 mating cycle specification. The 50 Ohm impedance and PTFE dielectric material are identical.

Q: How do the material differences affect performance?

A: The 122248 features nickel body finish and gold center contact plating, compared to the 031-2300-RFX silver plating. These material upgrades enhance corrosion resistance and contact longevity without modifying electrical characteristics. Both configurations maintain equivalent RF performance and impedance control.

Q: What packaging considerations apply to the substitute part?

A: The 031-2300-RFX ships in Bulk packaging, while the 122248 is supplied in Bag packaging. This difference affects handling and storage procedures but does not impact component functionality or electrical performance. Moisture Sensitivity Level remains 1 (Unlimited) for both parts.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 031-2300-RFX and 122248 are ROHS3 compliant and REACH affected, satisfying current EU regulatory requirements. The EAR99 export classification and 8536.69.4010 HTSUS code are identical for both parts.

Q: Can the 122248 be used in high-frequency applications up to 11 GHz?

A: Yes. The 122248 is rated for maximum frequency operation to 11 GHz, identical to the 031-2300-RFX. Both parts are suitable for RF and microwave applications within this frequency range.
