Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.5GL.AC39Z is determined by the following critical parameters:

• Connector Type & Position Count: Must be plug with male pins in 5-position configuration
• Termination Method: Solder cup termination required for PCB assembly compatibility
• Shell Size & Insert: M05 shell size with matching insert dimensions
• Contact Finish: Gold plating for mating surface to ensure electrical performance
• Fastening Mechanism: Push-pull connection with detent lock functionality
• Current & Temperature Ratings: Minimum 7A current capacity; operating range must encompass -50°C to 150°C
• Ingress Protection: IP50 dust protection classification
• Compliance: ROHS3 compliance and REACH unaffected status required

The substitute part S21MA7-P05MJG0-397S meets these core substitution criteria while maintaining functional equivalence for the specified applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.5GL.AC39Z and S21MA7-P05MJG0-397S maintain active product status and full ROHS3 compliance with REACH unaffected classification, ensuring regulatory alignment for industrial, medical, and automotive applications.

The PAA.M0.5GL.AC39Z provides an operating temperature range of -50°C to 150°C, supporting extended high-temperature applications. The S21MA7-P05MJG0-397S operates within -50°C to 120°C, suitable for standard industrial and medical environments where maximum temperature does not exceed 120°C.

Current rating differential is minimal, with the substitute part rated at 7.5A versus the primary part at 7A. Both connectors feature identical cable opening specifications, shell materials, and insert materials, ensuring mechanical and electrical compatibility within their respective temperature operating ranges.

Selection between these parts should be based on application temperature requirements and availability. The primary part supports the full extended temperature specification, while the substitute part is appropriate for applications operating within the -50°C to 120°C envelope.

Frequently Asked Questions (FAQ)

Q: Can the S21MA7-P05MJG0-397S replace the PAA.M0.5GL.AC39Z in all applications?

A: Substitution is valid for applications where the operating temperature does not exceed 120°C. The PAA.M0.5GL.AC39Z is required for applications requiring operation above 120°C up to 150°C.

Q: Are the mechanical dimensions compatible between these connectors?

A: Yes. Both connectors feature M05 shell size with identical cable opening specifications of 0.106" to 0.154" (2.70mm to 3.90mm), ensuring mechanical interchangeability in mating interfaces.

Q: What is the difference in fastening mechanisms?

A: The PAA.M0.5GL.AC39Z includes both push-pull and detent lock fastening, while the S21MA7-P05MJG0-397S features push-pull fastening. Both provide secure connection; the detent lock on the primary part offers additional mechanical retention.

Q: Do both parts meet the same compliance standards?

A: Yes. Both connectors are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial, medical, and automotive applications.

Q: What is the current-carrying capacity difference?

A: The S21MA7-P05MJG0-397S is rated at 7.5A compared to the PAA.M0.5GL.AC39Z at 7A. Both ratings are suitable for standard 5-position circular connector applications; the substitute part provides slightly higher current capacity.

Q: Are the contact materials identical?

A: Both connectors feature gold plating on mating surfaces. The substitute part specifies brass contact material, while the primary part does not specify contact material in the provided data. Both maintain gold finish for electrical performance.
