Key Parameters

Substitute Part Grouping Explanation

The ODU S11MA7-P10MCC0-3920 is identified as a substitute based on the following alignment of critical parameters:

• Connector Configuration: Both parts are 10-position circular connector plugs with male pins
• Termination Method: Both utilize solder cup termination for wire attachment
• Shell Material: Both employ Polysulfone (PSU) for the shell structure
• Contact Finish: Both feature gold-plated mating surfaces
• Mounting Style: Both are free-hanging, in-line configurations
• Fastening Mechanism: Both use push-pull fastening (PAA.M1.0GL.AC39R includes detent lock; S11MA7-P10MCC0-3920 uses standard push-pull)
• Environmental Protection: Both meet IP50 dust protection rating
• Cable Opening Dimensions: Both accommodate 0.106" ~ 0.154" (2.70mm ~ 3.90mm) cable sizes
• Insert Material: Both use Polyetheretherketone (PEEK) for the insert structure
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected

Parameter Comparison

Engineering Selection Recommendations

Both the PAA.M1.0GL.AC39R and S11MA7-P10MCC0-3920 are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications in medical, industrial, and automotive sectors.

The PAA.M1.0GL.AC39R offers a higher current rating of 3A and extended operating temperature range to 150°C, providing greater thermal headroom for high-temperature applications. The detent lock fastening mechanism provides additional mechanical security during connection cycles.

The S11MA7-P10MCC0-3920 operates within a 2.75A current specification and -50°C to 120°C temperature range. This part is suitable for applications where these electrical and thermal parameters are sufficient. Both connectors share identical cable opening dimensions, shell materials, contact finishes, and insert materials, ensuring mechanical and electrical compatibility within their respective rated parameters.

Selection between these parts should be based on specific application requirements for current capacity and maximum operating temperature, as well as fastening mechanism preference (detent lock versus standard push-pull).

Frequently Asked Questions (FAQ)

Q: Can the S11MA7-P10MCC0-3920 be used as a direct replacement for the PAA.M1.0GL.AC39R?

A: The S11MA7-P10MCC0-3920 is mechanically and electrically compatible for applications operating within its rated specifications: 2.75A maximum current and -50°C to 120°C operating temperature. Applications requiring the full 3A current rating or temperatures exceeding 120°C must use the PAA.M1.0GL.AC39R.

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

A: The primary differences are current rating (3A versus 2.75A), maximum operating temperature (150°C versus 120°C), and fastening mechanism (detent lock versus standard push-pull). All other electrical and mechanical parameters, including shell material, contact finish, termination type, and cable opening dimensions, are identical.

Q: Are both parts suitable for medical device applications?

A: Yes, both the PAA.M1.0GL.AC39R and S11MA7-P10MCC0-3920 are listed for medical applications and maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for medical device component selection.

Q: What is the significance of the cable opening dimension 0.106" ~ 0.154" (2.70mm ~ 3.90mm)?

A: This parameter specifies the acceptable cable diameter range for proper strain relief and backshell engagement. Both connectors accommodate identical cable sizes, ensuring interchangeability in cable assembly applications.

Q: Does the detent lock on the PAA.M1.0GL.AC39R provide any functional advantage?

A: The detent lock mechanism provides positive mechanical engagement during mating, preventing accidental disconnection. The S11MA7-P10MCC0-3920 uses standard push-pull fastening without detent locking. Selection depends on application requirements for connection security.
