Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3111F12-8P is determined by the following critical parameters:

• Connector Type: Receptacle configuration
• Number of Positions: 8 positions
• Shell Size - Insert: 12-8 specification
• Circular Connector Family: Compatible with 26482 style connectors

The substitute part MSW01E12-8P-SR meets these core substitution criteria. Both parts share identical position count (8), shell size (12-8), and receptacle configuration. The MSW01E12-8P-SR is manufactured by Milspecwest, LLC and belongs to the 26482 style connector family, which maintains mechanical and electrical compatibility with the MS3111F12-8P within the circular connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the MS3111F12-8P and MSW01E12-8P-SR maintain active product status, confirming ongoing manufacturer support and availability. The MSW01E12-8P-SR is classified as RoHS non-compliant with ECCN designation EAR99, consistent with military-grade circular connector specifications. Selection between these parts should be based on application requirements for mounting configuration (free hanging in-line for the substitute), termination method (solder for the substitute), and electrical performance parameters (7.5A current rating, 800V voltage rating for the substitute). Both parts are suitable for military applications and operate across the -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: What makes MSW01E12-8P-SR a valid substitute for MS3111F12-8P?

A: Both connectors share the critical substitution parameters: 8-position configuration, 12-8 shell size, receptacle type, and circular connector classification. Both are active products from established manufacturers in the circular connector category.

Q: Are there differences in mounting or termination between these parts?

A: Yes. The MSW01E12-8P-SR specifies free hanging (in-line) mounting with solder termination and bayonet lock fastening. The MS3111F12-8P does not provide these detailed specifications in the available data. Verify mounting and termination compatibility with your application requirements before substitution.

Q: What is the inventory status for each part?

A: The MS3111F12-8P has 1,098 units in stock. The MSW01E12-8P-SR has 897 units in stock. Both are available as new original components.

Q: Are there compliance or regulatory differences?

A: The MSW01E12-8P-SR is RoHS non-compliant and carries ECCN EAR99 designation, indicating military-grade classification. Confirm compliance requirements for your specific application before selection.

Q: What electrical performance should I expect from the substitute?

A: The MSW01E12-8P-SR is rated for 7.5A current and 800V voltage with operating temperature range of -55°C to 125°C. Verify these specifications meet your application requirements.
