Substitute Part Grouping Explanation

Substitution of the PAA.M0.9GL.AC52A is permissible with the ODU S11MA7-P09MCC0-5260 based on the following alignment of critical parameters:

Matching Parameters:

• Connector type: Plug with male pins
• Number of positions: 9
• Termination method: Solder cup
• Fastening mechanism: Push-Pull
• Shell material: Polysulfone (PSU)
• Contact finish: Gold plating
• Ingress protection: IP50 - Dust Protected
• Cable opening range: 0.157" ~ 0.205" (4.00mm ~ 5.20mm)
• Insert material: Polyetheretherketone (PEEK)
• Mounting type: Free Hanging (In-Line)
• Orientation: A
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Current rating: 3A (main part) vs. 2.75A (substitute) — substitute operates within acceptable amperage tolerance
• Operating temperature: -50°C ~ 150°C (main part) vs. -50°C ~ 120°C (substitute) — substitute covers standard industrial range with reduced upper limit
• Fastening type: Main part includes detent lock feature; substitute uses push-pull only — functional difference in locking mechanism
• Series designation: 1P (main part) vs. ODU MEDI-SNAP® (substitute) — different product lines with compatible mechanical interfaces

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M0.9GL.AC52A and S11MA7-P09MCC0-5260 maintain active production status and comply with ROHS3 and REACH requirements, making either suitable for new designs or production continuity. The primary selection criterion depends on application-specific current and temperature requirements.

The PAA.M0.9GL.AC52A is specified for applications requiring the full 3A current rating and extended operating temperature range to 150°C. This part is appropriate for high-temperature industrial and automotive environments.

The S11MA7-P09MCC0-5260 is suitable for applications operating within 2.75A current limits and maximum temperatures of 120°C. This substitute is appropriate for standard industrial and medical device applications within these thermal and electrical constraints.

Both connectors share identical mechanical interfaces, cable opening specifications, and contact finish characteristics, ensuring physical and electrical compatibility within their respective rated parameters.

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P09MCC0-5260 be used as a direct replacement for the PAA.M0.9GL.AC52A in all applications?

A: Substitution is permissible only when the application operates within the substitute's current rating (2.75A maximum) and temperature range (-50°C to 120°C). Applications requiring the full 3A rating or temperatures exceeding 120°C must use the PAA.M0.9GL.AC52A.

Q: What is the difference between the fastening mechanisms of these two connectors?

A: The PAA.M0.9GL.AC52A includes both push-pull and detent lock fastening, providing positive mechanical locking. The S11MA7-P09MCC0-5260 uses push-pull fastening only. Both mechanisms are compatible with standard mating receptacles designed for 9-position circular connectors.

Q: Are the shell sizes equivalent between these parts?

A: The PAA.M0.9GL.AC52A specifies shell size M09, while the S11MA7-P09MCC0-5260 specifies shell size 1. Both designations refer to compatible 9-position circular connector interfaces with identical mechanical dimensions and mating characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PAA.M0.9GL.AC52A and S11MA7-P09MCC0-5260 are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). Both are classified under ECCN EAR99 and HTSUS 8536.69.4020.

Q: What is the inventory status for these parts?

A: The PAA.M0.9GL.AC52A has 1096 units in stock. The S11MA7-P09MCC0-5260 has 974 units in stock. Both are available as new original components.
