Engineering Selection Recommendations

Both the PAA.M0.4GL.AC65N and S11MA7-P04MJG0-6580 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The substitute part S11MA7-P04MJG0-6580 from ODU is mechanically and electrically compatible for applications within the overlapping operating temperature range of -50°C to 120°C. The substitute part carries a higher current rating of 10A compared to the original 8A specification, making it suitable for equivalent or lower-current applications. Selection between these parts should be based on availability, supply chain requirements, and specific application temperature constraints. The original PAA.M0.4GL.AC65N maintains a higher maximum operating temperature rating of 150°C, which may be required for high-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P04MJG0-6580 be used as a direct replacement for PAA.M0.4GL.AC65N?

A: Yes, for applications operating within -50°C to 120°C. Both connectors share identical mechanical dimensions, pin count, termination method, shell material, and contact finish. The substitute part meets or exceeds the original part's current rating specification.

Q: What is the difference in fastening type between these two connectors?

A: The PAA.M0.4GL.AC65N specifies push-pull with detent lock, while the S11MA7-P04MJG0-6580 specifies push-pull fastening. Both employ push-pull mating mechanisms; the detent lock specification difference should be evaluated against application requirements for connector retention.

Q: Why do the shell size designations differ (M04 versus 1)?

A: M04 and 1 represent different manufacturer naming conventions for equivalent shell sizes within the 4-position circular connector category. The mechanical fit and mating interface are equivalent between these parts.

Q: Are there temperature limitations when substituting these parts?

A: The original PAA.M0.4GL.AC65N operates to 150°C, while the substitute S11MA7-P04MJG0-6580 operates to 120°C. Applications requiring operation above 120°C must use the original part. Both parts operate identically in the -50°C to 120°C range.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PAA.M0.4GL.AC65N and S11MA7-P04MJG0-6580 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial, medical, and automotive applications.

Q: What is the current rating difference, and does it affect substitution?

A: The substitute part S11MA7-P04MJG0-6580 is rated for 10A compared to the original 8A. This higher rating makes the substitute suitable for applications at or below the original 8A specification. Applications requiring exactly 8A operation can safely use the 10A-rated substitute.
