Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LEMO PAA.M1.4GL.AC52V is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug with male pins, 14-position configuration
• Termination Method: Solder cup termination required
• Shell Material & Finish: Polysulfone (PSU) shell with gold contact finish
• Fastening Mechanism: Push-pull detent lock fastening
• Ingress Protection: IP50 dust protection rating
• Mounting Configuration: Free hanging (in-line) orientation
• Compliance: ROHS3 compliant, REACH unaffected

The ODU S11MA7-P14MCC0-5250 meets these core substitution criteria. Both parts share identical connector topology, termination approach, shell material composition, and environmental protection rating. Differences exist in operating temperature range and current rating, which must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the LEMO PAA.M1.4GL.AC52V and ODU S11MA7-P14MCC0-5250 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, industrial, and automotive sectors.

The LEMO part supports an extended operating temperature range of -50°C to 150°C, compared to the ODU part's -50°C to 120°C range. Applications requiring operation above 120°C must use the LEMO part.

The ODU part provides a higher current rating of 2.5A versus the LEMO part's 2A rating. Applications with current demands between 2A and 2.5A may use either part, while applications exceeding 2.5A require the LEMO part.

Both parts feature identical mechanical interfaces, shell materials, contact finishes, and ingress protection ratings, ensuring physical and electrical compatibility within the specified parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can the ODU S11MA7-P14MCC0-5250 be used as a direct replacement for the LEMO PAA.M1.4GL.AC52V?

A: Direct replacement is possible when application requirements fall within the ODU part's specifications. The ODU part operates to 120°C maximum and carries 2.5A maximum current. If your application requires temperatures above 120°C or operates at exactly 2A with no margin, the LEMO part is required.

Q: What are the critical compatibility factors between these two connectors?

A: Both connectors share 14-position male pin configuration, solder cup termination, polysulfone shell material, gold contact finish, push-pull fastening, and IP50 ingress protection. These parameters ensure mechanical and electrical interchangeability within their respective operating ranges.

Q: Are there differences in fastening mechanisms between these parts?

A: The LEMO part specifies push-pull with detent lock fastening. The ODU part specifies push-pull fastening. Both employ push-pull engagement, though the LEMO part includes an additional detent lock feature. This difference does not prevent substitution but should be noted for applications where detent lock functionality is required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, making them suitable for equivalent regulatory environments.

Q: What is the significance of the cable opening specification?

A: Both parts specify identical cable opening ranges of 0.157" to 0.205" (4.00mm to 5.20mm). This ensures compatible backshell and cable assembly interfaces.
