Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.4GL.AC52J is determined by the following critical parameters:

• Connector Configuration: 4-position plug with male pins and solder cup termination
• Fastening Mechanism: Push-pull detent lock engagement
• Shell Material: Polysulfone (PSU) construction
• Contact Finish: Gold-plated mating surfaces
• Mounting Style: Free hanging in-line configuration
• Environmental Protection: IP50 dust protection rating
• Termination Method: Solder cup for wire attachment
• Compliance: ROHS3 compliance and MSL 1 rating

The substitute part S11MA7-P04MJG0-5240 (ODU MEDI-SNAP®) meets these core substitution criteria. Both parts share identical connector type, position count, termination method, shell material, contact finish, fastening type, mounting configuration, ingress protection rating, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.4GL.AC52J and S11MA7-P04MJG0-5240 are active production parts with ROHS3 compliance and MSL 1 ratings, making them suitable for equivalent component selection in applications requiring 4-position circular connectors with solder cup termination.

The PAA.M0.4GL.AC52J supports an operating temperature range of -50°C to 150°C with an 8A current rating. The S11MA7-P04MJG0-5240 operates from -50°C to 120°C with a 10A current rating. Selection between these parts depends on specific application temperature and current requirements. If the application requires sustained operation above 120°C, the LEMO part is the appropriate choice. If current requirements do not exceed 8A and operating temperatures remain below 120°C, the ODU part provides equivalent functionality with higher current capacity margin.

Both connectors feature identical shell material (Polysulfone PSU), contact finish (gold), fastening mechanism (push-pull), mounting configuration (free hanging in-line), and ingress protection (IP50). Cable opening specifications are identical at 0.157" to 0.205" (4.00mm to 5.20mm).

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P04MJG0-5240 directly replace the PAA.M0.4GL.AC52J in all applications?

A: The S11MA7-P04MJG0-5240 is functionally equivalent for applications operating below 120°C and requiring current ratings up to 8A. If your application requires sustained operation above 120°C, the PAA.M0.4GL.AC52J is required due to its extended temperature rating to 150°C.

Q: What are the key compatibility criteria for these connectors?

A: Both connectors share identical specifications for connector type (4-position plug, male pins), termination method (solder cup), shell material (Polysulfone PSU), contact finish (gold), fastening type (push-pull), mounting style (free hanging in-line), ingress protection (IP50), and compliance certifications (ROHS3, MSL 1).

Q: Are there differences in current handling between these parts?

A: The PAA.M0.4GL.AC52J is rated for 8A, while the S11MA7-P04MJG0-5240 is rated for 10A. Both parts are suitable for applications requiring 8A or less. The ODU part provides additional current capacity margin.

Q: Do these connectors use the same cable opening specifications?

A: Yes. Both the PAA.M0.4GL.AC52J and S11MA7-P04MJG0-5240 accept cable diameters from 0.157" to 0.205" (4.00mm to 5.20mm).

Q: What is the difference between the LEMO 1P series and the ODU MEDI-SNAP® series?

A: These are different manufacturer product lines. The 1P series is LEMO's designation, while MEDI-SNAP® is ODU's series name. Despite different series classifications, both connectors meet identical electrical and mechanical specifications for 4-position circular connector plugs with solder cup termination.

Q: Are both parts available in the same packaging?

A: The PAA.M0.4GL.AC52J is available in standard packaging with 1,002 units in stock. The S11MA7-P04MJG0-5240 is supplied in bulk packaging with 905 units in stock. Verify packaging requirements for your procurement process.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both the PAA.M0.4GL.AC52J and S11MA7-P04MJG0-5240 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings.
