Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.5GL.AC52N is determined by strict equivalence across the following critical parameters:

• Connector Configuration: Plug with male pins, 5-position circular interface
• Termination Method: Solder cup for wire attachment
• Shell Material & Finish: Polysulfone construction with gold-plated mating contacts
• Mechanical Interface: Push-pull fastening with detent lock, IP50 ingress protection
• Electrical Performance: Minimum 7A current rating capability
• Environmental Compliance: ROHS3 compliance and REACH unaffected status

The substitute part S11MA7-P05MJG0-5280 (ODU MEDI-SNAP®) maintains these core parameters, enabling direct functional replacement in applications where the connector interface specifications are the controlling design requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.5GL.AC52N and S11MA7-P05MJG0-5280 maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial, medical, and automotive applications. The substitute part demonstrates equivalent mechanical and electrical interface specifications with a higher current rating (7.5A versus 7A) and comparable operating temperature range (-50°C to 120°C versus -50°C to 150°C). Selection between these parts should be based on application-specific temperature requirements and supply chain availability. Both connectors are active production parts with established inventory levels.

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P05MJG0-5280 directly replace the PAA.M0.5GL.AC52N in existing designs?

A: Direct replacement is possible when the application operating temperature does not exceed 120°C. The substitute part maintains identical connector geometry, pin configuration, termination method, and ingress protection rating. Mechanical and electrical interface compatibility is preserved.

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

A: The primary differences are the maximum operating temperature (PAA.M0.5GL.AC52N: 150°C; S11MA7-P05MJG0-5280: 120°C) and current rating (7A versus 7.5A). Both connectors share identical shell material, contact finish, cable opening dimensions, and PEEK insert material.

Q: Are both parts compliant with industry standards?

A: Both parts are ROHS3 compliant and REACH unaffected. They meet the regulatory requirements for industrial, medical, and automotive applications.

Q: What is the significance of the cable opening specification?

A: The cable opening range of 0.157" to 0.205" (4.00mm to 5.20mm) defines the acceptable wire gauge diameter for solder cup termination. Both connectors support identical cable opening specifications, ensuring compatibility with the same wire sizes.

Q: Does the Moisture Sensitivity Level difference affect substitution?

A: The PAA.M0.5GL.AC52N is rated MSL 1 (Unlimited), while the S11MA7-P05MJG0-5280 is listed as Not Applicable. This difference does not affect functional substitution but may influence storage and handling procedures based on manufacturer guidelines.
