Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAA.M1.4GL.AC39A are identified based on strict equivalence across the following critical parameters:

• Connector Configuration: 14-position plug with male pins
• Termination Method: Solder cup
• Contact Finish: Gold plating on mating surfaces
• Ingress Protection: IP50 dust protection rating
• Shell Material: Polysulfone (PSU)
• Insert Material: Polyetheretherketone (PEEK)
• Fastening Mechanism: Push-Pull connection type
• Mounting Style: Free hanging (in-line)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected

The substitute part S11MA7-P14MCC0-3960 (ODU MEDI-SNAP® series) meets these core equivalence criteria. Variations in current rating, maximum operating temperature, and fastening detent features are noted in the parameter comparison table below.

Engineering Selection Recommendations

Primary Part (PAA.M1.4GL.AC39A - LEMO)

Select this part when:

• Operating temperature range of -50°C to 150°C is required
• Detent lock fastening mechanism is specified in the design
• LEMO series compatibility is mandated by system architecture
• Automotive applications require LEMO connector standardization

Substitute Part (S11MA7-P14MCC0-3960 - ODU MEDI-SNAP®)

Select this part when:

• Operating temperature maximum of 120°C is acceptable
• Push-pull fastening without detent lock meets functional requirements
• Higher current rating of 2.5A provides design margin
• ODU MEDI-SNAP® series integration is compatible with system design
• Medical or military application certifications are required

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial, medical, and testing equipment applications.

Frequently Asked Questions (FAQ)

Q: Can the ODU S11MA7-P14MCC0-3960 directly replace the LEMO PAA.M1.4GL.AC39A in all applications?

A: Direct replacement depends on application-specific requirements. Both connectors share 14-position configuration, solder cup termination, gold contact finish, and IP50 ingress protection. However, the LEMO part includes a detent lock fastening mechanism absent in the ODU part, and the LEMO part supports higher maximum operating temperature (150°C vs. 120°C). Verify that your application does not require these specific features before substitution.

Q: What is the significance of the different shell size designations (M14 vs. 1)?

A: The LEMO part uses M14 designation while the ODU part uses "1" designation. These represent different manufacturer nomenclature systems for shell size. Physical compatibility between these connectors cannot be confirmed based on the provided parameters alone.

Q: Are both parts suitable for medical device applications?

A: Both parts list medical applications in their specification. Both maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Confirm that your specific medical device requirements align with the operating temperature and current rating specifications of the selected part.

Q: What is the difference in current rating between these parts?

A: The LEMO PAA.M1.4GL.AC39A is rated for 2A maximum current, while the ODU S11MA7-P14MCC0-3960 is rated for 2.5A. The higher ODU rating provides additional design margin but does not indicate superior performance in all applications. Select based on your circuit's actual current requirements.

Q: Can these connectors be used interchangeably in automotive applications?

A: The LEMO part explicitly lists automotive applications, while the ODU part does not. If automotive application compliance is required, the LEMO PAA.M1.4GL.AC39A is the specified choice. The ODU part may be suitable for industrial or medical applications where automotive certification is not mandated.
