Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.4GL.AC39R is determined by the following critical parameters:

• Connector Configuration: 4-position plug with male pins and solder cup termination
• Shell Material & Finish: Polysulfone (PSU) construction with gold-plated contacts
• Fastening Mechanism: Push-pull detent lock compatibility
• Mounting Profile: Free hanging in-line configuration
• Environmental Protection: IP50 dust protection rating
• Electrical Performance: Current and voltage handling capacity
• Temperature Operating Range: Functional performance across specified thermal limits
• Compliance Standards: RoHS3 and REACH compliance status

The substitute part S11MA7-P04MJG0-3920 (ODU MEDI-SNAP®) meets these core substitution criteria while maintaining equivalent mechanical and electrical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial, medical, and automotive applications. The PAA.M0.4GL.AC39R operates across a wider temperature range (-50°C to 150°C) compared to the S11MA7-P04MJG0-3920 (-50°C to 120°C). Selection between these parts should be based on application-specific temperature requirements. The ODU substitute provides a higher current rating (10A versus 8A), which may offer additional design margin in power distribution applications. Both connectors share identical mechanical interfaces, shell materials, contact finishes, and ingress protection ratings, supporting direct substitution in applications where the temperature and current specifications align.

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P04MJG0-3920 be used as a direct replacement for the PAA.M0.4GL.AC39R?

A: The S11MA7-P04MJG0-3920 is mechanically and electrically compatible for most applications. However, applications requiring operation above 120°C must use the PAA.M0.4GL.AC39R, which is rated to 150°C. Both parts share identical 4-position solder cup configuration, PSU shell material, gold contact finish, and IP50 protection.

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

A: The primary differences are operating temperature range (LEMO: -50°C to 150°C; ODU: -50°C to 120°C) and current rating (LEMO: 8A; ODU: 10A). Both maintain equivalent mechanical interfaces and environmental protection ratings.

Q: Are both parts RoHS3 compliant?

A: Yes, both the PAA.M0.4GL.AC39R and S11MA7-P04MJG0-3920 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and medical applications.

Q: What is the cable opening specification for these connectors?

A: Both connectors accept cable diameters between 0.106" and 0.154" (2.70mm to 3.90mm), providing equivalent cable accommodation.

Q: Can these connectors be used in automotive applications?

A: The PAA.M0.4GL.AC39R is specified for automotive applications. The S11MA7-P04MJG0-3920 is specified for industrial and medical applications. Automotive application requirements should be verified against the ODU part's qualification status before substitution.
