Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAA.M0.9GL.AC52J is determined by alignment across the following critical parameters:

• Connector Configuration: Plug with male pins, 9-position circular connector
• Termination Method: Solder cup for wire attachment
• Shell Material & Protection: Polysulfone construction with IP50 ingress protection
• Contact System: Gold-plated mating surface for reliable electrical connection
• Mechanical Interface: Push-pull fastening with compatible shell sizing
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The substitute part S11MA7-P09MCC0-5240 (ODU MEDI-SNAP®) meets these core substitution criteria. Variations in current rating (2.75A vs. 3A) and maximum operating temperature (-50°C ~ 120°C vs. -50°C ~ 150°C) represent parameter differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.9GL.AC52J and S11MA7-P09MCC0-5240 are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for regulated industrial, medical, and automotive applications.

The PAA.M0.9GL.AC52J supports a maximum current rating of 3A and operating temperature range of -50°C to 150°C. The S11MA7-P09MCC0-5240 operates within -50°C to 120°C with a current rating of 2.75A. Selection between these parts depends on application-specific thermal and current requirements. Applications operating above 120°C or requiring current loads exceeding 2.75A necessitate the PAA.M0.9GL.AC52J. Both connectors share identical mechanical interfaces, cable opening specifications, and gold-plated contact finishes, ensuring physical and electrical compatibility within their respective operating parameters.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P09MCC0-5240 be used as a direct replacement for PAA.M0.9GL.AC52J?

A: Physical and electrical compatibility exists between these connectors. The substitute part meets core substitution criteria including 9-position configuration, solder cup termination, gold-plated contacts, and IP50 protection. However, the reduced current rating (2.75A vs. 3A) and lower maximum operating temperature (-50°C ~ 120°C vs. -50°C ~ 150°C) must be evaluated against application specifications before substitution.

Q: What are the key differences between these two connectors?

A: The primary differences are current rating and maximum operating temperature. The PAA.M0.9GL.AC52J supports 3A at temperatures up to 150°C, while the S11MA7-P09MCC0-5240 is rated for 2.75A with a maximum temperature of 120°C. Both connectors feature identical shell sizing, cable opening specifications, and contact finish systems.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the PAA.M0.9GL.AC52J and S11MA7-P09MCC0-5240 are ROHS3 compliant and REACH unaffected, meeting current environmental standards for industrial and medical applications.

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

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

Q: Does fastening type affect interchangeability?

A: The PAA.M0.9GL.AC52J features push-pull with detent lock, while the S11MA7-P09MCC0-5240 uses push-pull fastening. Both mechanisms provide secure mating and demating. The detent lock in the LEMO part provides additional mechanical retention. This difference does not prevent physical substitution but should be considered for applications requiring specific locking characteristics.
