Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PAA.M0.9GL.AC39G are identified based on the following critical parameters that must align for functional equivalence:

• Connector Type & Position Count: Plug configuration with 9 male pins
• Termination Method: Solder cup termination
• Shell Material: Polysulfone (PSU) construction
• Contact Finish: Gold plating on mating surfaces
• Fastening Mechanism: Push-Pull connection system
• Ingress Protection: IP50 dust protection rating
• Operating Temperature Range: Minimum -50°C to 150°C capability
• Current Rating: Minimum 3A capacity
• Compliance: ROHS3 and REACH compliance status

The identified substitute part S11MA7-P09MCC0-3970 (ODU MEDI-SNAP®) meets these core electrical and mechanical requirements, enabling direct functional replacement in applications where the main part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

The PAA.M0.9GL.AC39G and S11MA7-P09MCC0-3970 are functionally equivalent for most standard applications. Both parts maintain ROHS3 and REACH compliance, ensuring regulatory alignment for industrial, medical, and automotive deployments.

Selection between these parts should account for the following provided specifications:

• Current Capacity: The main part (PAA.M0.9GL.AC39G) is rated for 3A, while the substitute (S11MA7-P09MCC0-3970) is rated for 2.75A. Applications requiring the full 3A capacity should prioritize the main part.

• Operating Temperature Upper Limit: The main part operates to 150°C, while the substitute operates to 120°C. High-temperature applications exceeding 120°C require the main part.

• Fastening Mechanism: The main part includes detent lock functionality in addition to push-pull operation. Applications requiring detent lock security should specify the main part.

Both parts share identical mechanical interfaces, cable opening specifications, and material compositions, supporting direct substitution in applications within the substitute part's electrical and thermal ratings.

Frequently Asked Questions (FAQ)

Q: Can S11MA7-P09MCC0-3970 directly replace PAA.M0.9GL.AC39G in all applications?

A: Direct replacement is possible when application requirements do not exceed the substitute part's specifications. The substitute part is rated for 2.75A maximum current and 120°C maximum operating temperature. Applications requiring 3A current capacity or operation above 120°C must use the main part.

Q: Are the mechanical interfaces identical between these two connectors?

A: Yes. Both connectors feature 9-position solder cup termination, identical cable opening ranges (0.106" ~ 0.154"), push-pull fastening systems, and polysulfone shell construction. Physical mating interfaces are compatible.

Q: What is the difference in fastening mechanisms?

A: The PAA.M0.9GL.AC39G includes both push-pull and detent lock fastening, while the S11MA7-P09MCC0-3970 features push-pull fastening only. Applications requiring detent lock engagement should use the main part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PAA.M0.9GL.AC39G and S11MA7-P09MCC0-3970 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and medical applications.

Q: What is the significance of the shell material specification?

A: Both connectors use polysulfone (PSU) for shell construction, providing equivalent mechanical durability, chemical resistance, and thermal stability across the specified operating temperature ranges.

Q: Are there packaging differences between these parts?

A: The main part is packaged in standard format, while the substitute part is supplied in bulk packaging. This distinction affects inventory management and procurement processes but does not impact connector functionality or performance.
