Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3111F18-32P is determined by the following critical parameters:

• Connector Type: Receptacle configuration
• Number of Positions: 32 positions
• Shell Size - Insert: 18-32 specification
• Circular Connector Category: Maintains compatibility within the circular connector family
• Mounting and Termination: Physical and electrical interface requirements

The MSW01E18-32P-SR qualifies as a substitute based on matching the 32-position configuration and 18-32 shell size specification. Both parts function as receptacles within the circular connector category and maintain compatibility with the same mating interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both the MS3111F18-32P and MSW01E18-32P-SR maintain active product status, confirming ongoing manufacturer support and availability. The MSW01E18-32P-SR is manufactured by Milspecwest, LLC and carries RoHS non-compliant status, consistent with military-grade circular connector applications. Selection between these parts should be based on specific application requirements regarding mounting configuration, termination method, and environmental compliance specifications. The MSW01E18-32P-SR provides documented electrical ratings (7.5A at 800V) and operating temperature range (-55°C ~ 125°C), which may be relevant for applications with defined performance requirements.

Frequently Asked Questions (FAQ)

Q: What makes MSW01E18-32P-SR a valid substitute for MS3111F18-32P?

A: Both connectors share the critical specifications of 32-position configuration and 18-32 shell size specification. Both are classified as circular connector receptacles and maintain compatibility within the same connector family.

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

A: Yes. The MSW01E18-32P-SR specifies free hanging (in-line) mounting with solder termination and bayonet lock fastening. The MS3111F18-32P does not have these specifications documented in the available data. Verify mounting and termination compatibility with your specific application requirements before substitution.

Q: What is the difference in packaging between these parts?

A: The MS3111F18-32P is supplied in bulk packaging, while the MSW01E18-32P-SR is supplied in bag packaging. This affects handling, storage, and inventory management but does not impact functional compatibility.

Q: Are both parts suitable for military applications?

A: The MSW01E18-32P-SR is explicitly designated for military applications. The MS3111F18-32P does not have application specifications documented. Confirm application suitability based on your specific military or industrial requirements.

Q: What should I verify before implementing a substitution?

A: Verify that the mounting type (free hanging in-line), termination method (solder), and fastening mechanism (bayonet lock) of the MSW01E18-32P-SR are compatible with your circuit design and assembly process. Confirm that the electrical ratings (7.5A, 800V) and operating temperature range (-55°C ~ 125°C) meet your application specifications.
