Key Parameters

Substitute Part Grouping Explanation

The substitute part S11MA7-P04MJG0-3980 (ODU MEDI-SNAP®) is identified as equivalent based on the following critical parameters that determine substitution compatibility:

• Connector Configuration: Both parts are 4-position circular connector plugs with male pins and solder cup termination
• Fastening Mechanism: Both utilize push-pull fastening with detent lock functionality
• Contact Finish: Both feature gold-plated mating surfaces
• Shell Material: Both employ polysulfone (PSU) construction
• Insert Material: Both use polyetheretherketone (PEEK) inserts
• Ingress Protection: Both provide IP50 dust protection rating
• Cable Opening Range: Both accommodate 0.106" ~ 0.154" (2.70mm ~ 3.90mm) cable diameters
• Compliance: Both are ROHS3 compliant with REACH unaffected status
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

Differences in current rating (8A vs. 10A), operating temperature range (-50°C ~ 150°C vs. -50°C ~ 120°C), and shell size designation (M04 vs. 1) do not preclude substitution when application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.4GL.AC39N and S11MA7-P04MJG0-3980 maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on application-specific requirements:

For applications operating at temperatures exceeding 120°C, the PAA.M0.4GL.AC39N supports the extended upper temperature limit of 150°C. For applications with current requirements up to 10A, the S11MA7-P04MJG0-3980 provides additional current capacity. Both parts are suitable for automotive, industrial, medical, and testing equipment applications where 4-position circular connector plugs with solder cup termination are specified.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P04MJG0-3980 be used as a direct replacement for PAA.M0.4GL.AC39N?

A: Substitution is permissible when application requirements fall within the operating parameters of the substitute part. The substitute supports 10A current (exceeding the 8A requirement) and operates to 120°C. Applications requiring operation above 120°C require the primary part.

Q: What are the critical compatibility factors for these connectors?

A: The 4-position configuration, solder cup termination, push-pull fastening, gold contact finish, polysulfone shell construction, and IP50 ingress protection are the primary compatibility factors. Both parts meet these specifications identically.

Q: Are there packaging differences between these parts?

A: The PAA.M0.4GL.AC39N is supplied in standard packaging, while the S11MA7-P04MJG0-3980 is supplied in bulk packaging. Inventory availability differs: 826 units for the primary part and 1055 units for the substitute.

Q: Do these connectors require any special handling or storage considerations?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What applications are these connectors suitable for?

A: Both connectors are specified for automotive, industrial, medical, and testing equipment applications. The ODU substitute additionally lists military applications.
