Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the MS3111F20-41P is based on the following critical parameters that determine functional and mechanical compatibility:

• Connector Type: Receptacle configuration
• Number of Positions: 41-position contact arrangement
• Shell Size - Insert: 20-41 specification
• Category: Circular Connectors classification
• Product Status: Active availability

The MSW01E20-41P-SR from Milspecwest, LLC qualifies as a substitute based on matching the 41-position circular connector receptacle category with identical shell size-insert specification (20-41). Both components function as receptacle connectors within the circular connector family, enabling direct functional substitution in applications where the specified parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the MS3111F20-41P and MSW01E20-41P-SR maintain Active product status, indicating current manufacturer support and availability. The MSW01E20-41P-SR is classified as RoHS non-compliant, which may impact selection in applications subject to RoHS regulatory requirements. The main part (MS3111F20-41P) does not specify RoHS status in the provided data.

Selection between these components should be based on:

• Regulatory compliance requirements (RoHS status)
• Specific application environmental conditions
• Inventory availability and lead time considerations
• Supplier qualification and quality assurance protocols

Both components are available in new original condition with comparable stock levels, supporting either selection for immediate deployment.

Frequently Asked Questions (FAQ)

Q: What makes the MSW01E20-41P-SR a valid substitute for the MS3111F20-41P?

A: Both components are 41-position circular connector receptacles with matching shell size-insert specifications (20-41). They share the same connector category and position count, which are the primary parameters determining functional compatibility in circular connector applications.

Q: Are there differences in electrical or mechanical specifications between these parts?

A: The MSW01E20-41P-SR provides additional specification data including current rating (7.5A, 13A), voltage rating (800V), operating temperature range (-55°C ~ 125°C), and fastening type (Bayonet Lock). The MS3111F20-41P input data does not include these detailed specifications for direct comparison.

Q: What is the significance of the RoHS non-compliant status for the MSW01E20-41P-SR?

A: RoHS non-compliance indicates the component may contain restricted substances. Applications subject to RoHS regulations (primarily in EU markets and certain industries) may require components with RoHS-compliant status. Verify regulatory requirements for your specific application before selection.

Q: Can these connectors be used interchangeably in existing designs?

A: Functional interchangeability depends on the complete electrical and mechanical requirements of the application. Both components match in position count and shell size-insert specification. Verify all application-specific requirements including voltage, current, temperature range, and environmental conditions before implementation.

Q: What packaging considerations apply to these parts?

A: The MS3111F20-41P is supplied in Bulk packaging. The MSW01E20-41P-SR packaging specification is not provided in the available data. Confirm packaging requirements and quantities needed for your procurement process.
