Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M1.4GL.AC39G is determined by the following critical parameters:

• Connector Type & Position Count: Both main and substitute parts must be 14-position circular connector plugs with male pins
• Termination Method: Solder cup termination is required for compatibility with existing PCB layouts and assembly processes
• Fastening Mechanism: Push-pull fastening is the primary requirement; detent lock is an additional feature in the main part
• Contact Finish: Gold plating on mating surfaces ensures equivalent electrical performance and corrosion resistance
• Mounting Configuration: Free hanging (in-line) mounting type must be maintained
• Ingress Protection: IP50 rating provides equivalent environmental sealing
• Operating Temperature: The substitute part must support the application's thermal requirements
• Current Rating: The substitute must meet or exceed the current-carrying capacity requirements
• Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory equivalence

The substitute part S11MA7-P14MCC0-3970 (ODU MEDI-SNAP®) meets these core substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (PAA.M1.4GL.AC39G): Select this LEMO connector when the detent lock fastening feature is required for the application. The extended operating temperature range to 150°C supports high-temperature environments. Both parts maintain active production status and full regulatory compliance.

Substitute Part (S11MA7-P14MCC0-3970): The ODU MEDI-SNAP® connector is suitable as a substitute when:

• The detent lock feature is not a functional requirement
• Operating temperatures do not exceed 120°C
• Higher current capacity (2.5A vs. 2A) is beneficial or required

Both parts are ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory standing. Selection between these parts should be based on specific application requirements regarding fastening mechanism and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can the ODU S11MA7-P14MCC0-3970 directly replace the LEMO PAA.M1.4GL.AC39G in all applications?

A: Direct substitution is possible for applications where the detent lock feature is not required and operating temperatures remain below 120°C. The 14-position configuration, solder cup termination, gold contact finish, and IP50 ingress protection are identical between both parts. Verify application-specific fastening and thermal requirements before substitution.

Q: What is the difference in fastening mechanisms between these two connectors?

A: The LEMO PAA.M1.4GL.AC39G includes both push-pull and detent lock fastening, providing positive mechanical locking. The ODU S11MA7-P14MCC0-3970 features push-pull fastening only. Applications requiring positive mechanical retention should use the LEMO part.

Q: Are there differences in current-carrying capacity?

A: The ODU substitute is rated for 2.5A compared to the LEMO part's 2A rating. The substitute exceeds the current requirement and is suitable for applications requiring the original 2A specification.

Q: What is the maximum operating temperature difference between these parts?

A: The LEMO PAA.M1.4GL.AC39G operates to 150°C, while the ODU S11MA7-P14MCC0-3970 operates to 120°C. Applications requiring operation above 120°C must use the LEMO part.

Q: Are both connectors compliant with RoHS and REACH regulations?

A: Yes. Both the LEMO PAA.M1.4GL.AC39G and ODU S11MA7-P14MCC0-3970 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Do these connectors have identical cable opening specifications?

A: Yes. Both connectors accept cable diameters in the range of 0.106" to 0.154" (2.70mm to 3.90mm), ensuring compatibility with the same cable specifications.
