Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAA.M1.4GL.AC52G are identified based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

• Connector Type: Plug, Male Pins
• Number of Positions: 14
• Termination: Solder Cup
• Shell Material: Polysulfone (PSU)
• Contact Finish - Mating: Gold
• Ingress Protection: IP50 - Dust Protected
• Mounting Type: Free Hanging (In-Line)
• Cable Opening: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Insert Material: Polyetheretherketone (PEEK)

Allowable Variations:

• Current Rating: Substitute may exceed the main part rating (2A minimum required)
• Operating Temperature: Substitute must support the main part's range or higher
• Fastening Type: Variations permitted if mechanical compatibility is maintained
• Shell Size designation: Different nomenclature systems acceptable if physical dimensions align

The substitute S11MA7-P14MCC0-5270 meets all mandatory matching parameters and provides allowable variations in current rating and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M1.4GL.AC52G and S11MA7-P14MCC0-5270 are active products with ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations.

The PAA.M1.4GL.AC52G supports an operating temperature range of -50°C to 150°C. The substitute S11MA7-P14MCC0-5270 operates within -50°C to 120°C. Selection between these parts should account for application temperature requirements. If the application requires sustained operation above 120°C, the PAA.M1.4GL.AC52G is the appropriate choice.

The S11MA7-P14MCC0-5270 provides a higher current rating of 2.5A compared to the 2A rating of the PAA.M1.4GL.AC52G, offering additional margin for applications with higher current demands.

Both connectors share identical mechanical interfaces, shell materials, contact finishes, and ingress protection ratings, ensuring mechanical and electrical compatibility in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P14MCC0-5270 be used as a direct replacement for the PAA.M1.4GL.AC52G?

A: The S11MA7-P14MCC0-5270 is mechanically and electrically compatible with the PAA.M1.4GL.AC52G for applications operating within -50°C to 120°C. Both connectors feature identical 14-position solder cup termination, gold-plated contacts, IP50 ingress protection, and PSU shell construction. The substitute part supports higher current (2.5A vs 2A). Applications requiring operation above 120°C must use the PAA.M1.4GL.AC52G.

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

A: The primary differences are operating temperature range and current rating. The PAA.M1.4GL.AC52G operates from -50°C to 150°C with a 2A current rating, while the S11MA7-P14MCC0-5270 operates from -50°C to 120°C with a 2.5A current rating. The fastening mechanism differs slightly (detent lock vs. standard push-pull), though both provide secure connections. All other electrical and mechanical parameters are equivalent.

Q: Are both parts available in the same packaging format?

A: The PAA.M1.4GL.AC52G is available in standard packaging, while the S11MA7-P14MCC0-5270 is supplied in bulk packaging. Both are currently in stock with active product status.

Q: What compliance certifications apply to both parts?

A: Both the PAA.M1.4GL.AC52G and S11MA7-P14MCC0-5270 are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and share the same HTSUS code (8536.69.4020).

Q: How do the shell size designations M14 and 1 relate to each other?

A: The M14 designation (LEMO) and shell size 1 (ODU MEDI-SNAP®) represent equivalent physical dimensions for 14-position circular connectors. These different nomenclature systems are used by their respective manufacturers but result in mechanically compatible interfaces.
