Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M1.4GL.AC52N is determined by the following critical parameters:

• Connector Configuration: 14-position circular connector plug with male pins
• Termination Method: Solder cup termination
• Shell Material: Polysulfone (PSU) construction
• Contact Finish: Gold plating on mating surfaces
• Mounting Configuration: Free hanging, in-line orientation
• Ingress Protection: IP50 dust protection rating
• Mechanical Interface: Push-pull fastening with compatible shell sizes
• Environmental Compliance: ROHS3 compliance and REACH unaffected status

The substitute part S11MA7-P14MCC0-5280 (ODU MEDI-SNAP®) meets these core substitution criteria. Both parts share identical 14-position configurations, solder cup termination, PSU shell material, gold contact finish, IP50 ingress protection, and equivalent compliance certifications. Differences in current rating (2.5A vs. 2A), operating temperature upper limit (120°C vs. 150°C), and fastening mechanism (push-pull vs. push-pull with detent lock) must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M1.4GL.AC52N and S11MA7-P14MCC0-5280 are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for regulated industrial, medical, and automotive applications. Selection between these parts should be based on the following considerations:

PAA.M1.4GL.AC52N (LEMO) is the primary specification and should be selected when the application requires the detent lock fastening mechanism or operates at temperatures exceeding 120°C up to 150°C.

S11MA7-P14MCC0-5280 (ODU MEDI-SNAP®) is a qualified substitute when the application current requirement does not exceed 2.5A and operating temperatures remain within the -50°C to 120°C range. This part offers higher current capacity and is suitable for equivalent mechanical and electrical performance in the specified temperature window.

Both parts maintain identical 14-position configurations, solder cup termination, PSU construction, gold contact finish, and IP50 ingress protection, ensuring functional compatibility in applications where the noted parameter differences are acceptable.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P14MCC0-5280 be used as a direct replacement for PAA.M1.4GL.AC52N?

A: S11MA7-P14MCC0-5280 is a functional equivalent for applications where the operating temperature does not exceed 120°C and the fastening mechanism difference (absence of detent lock) is acceptable. Both parts share identical 14-position configurations, solder cup termination, PSU shell material, and gold contact finish. Verify application temperature requirements and fastening mechanism compatibility before substitution.

Q: What are the key differences between these two connector models?

A: The primary differences are: (1) fastening type—PAA.M1.4GL.AC52N includes detent lock while S11MA7-P14MCC0-5280 uses standard push-pull; (2) current rating—S11MA7-P14MCC0-5280 is rated for 2.5A versus 2A for PAA.M1.4GL.AC52N; (3) maximum operating temperature—PAA.M1.4GL.AC52N operates to 150°C while S11MA7-P14MCC0-5280 is limited to 120°C.

Q: Are both parts suitable for medical device applications?

A: Both parts are listed for medical applications and maintain ROHS3 compliance and unlimited MSL ratings. Medical device qualification requirements vary by application; consult design specifications and regulatory requirements for your specific use case.

Q: What is the significance of the PSU shell material and PEEK insert material?

A: Polysulfone (PSU) shell material provides chemical resistance and dimensional stability across the operating temperature range. Polyetheretherketone (PEEK) insert material offers high-temperature performance and mechanical strength. Both materials are standard for industrial and medical connector applications.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage practices apply. Solder cup terminations require appropriate soldering techniques during assembly.
