Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MS3111F22-55S are identified based on the following critical parameters that determine functional compatibility:

• Number of Positions: 55 positions (electrical contact count)
• Shell Size - Insert: 22-55 (mechanical envelope and mating interface)
• Connector Type: Receptacle with female sockets (functional role in assembly)
• Category: Circular Connectors (product family classification)
• Product Status: Active (current manufacturing availability)

The MSW01E22-55S-SR from Milspecwest, LLC satisfies all primary substitution criteria. Both parts share identical position count, shell size designation, and receptacle configuration, enabling direct functional replacement in applications requiring 55-position circular connector receptacles with 22-55 shell specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MS3111F22-55S and MSW01E22-55S-SR maintain Active product status, confirming current manufacturing support and availability from their respective manufacturers. The MSW01E22-55S-SR is classified as RoHS non-compliant, which must be evaluated against application requirements and regulatory constraints.

Selection between these parts should be based on:

• Compliance requirements (RoHS status applicability to end application)
• Packaging format preference (Bulk versus Bag)
• Inventory availability and lead time considerations
• Specific electrical ratings (current and voltage) required by the application circuit

Frequently Asked Questions (FAQ)

Q: Can the MSW01E22-55S-SR directly replace the MS3111F22-55S in existing designs?

A: Both parts share identical position count (55) and shell size designation (22-55), with matching receptacle configuration. Direct mechanical and electrical compatibility is established for these core parameters. Verification of additional specifications such as termination method, mounting configuration, and compliance requirements is necessary for specific applications.

Q: What are the key differences between these two 55-position receptacles?

A: The primary differences are manufacturer origin (Amphenol Industrial Operations versus Milspecwest, LLC), packaging format (Bulk versus Bag), and documented electrical ratings. The MSW01E22-55S-SR specifies solder termination, bayonet lock fastening, and operating temperature range of -55°C to 125°C, while the MS3111F22-55S does not provide these detailed specifications in the available data.

Q: Does RoHS non-compliance of the MSW01E22-55S-SR affect substitution eligibility?

A: RoHS compliance status is application-dependent. Applications subject to RoHS regulations (primarily consumer electronics and certain industrial markets) require compliant components. Applications without RoHS mandates may use non-compliant parts. This determination must be made at the design and procurement level based on end-use classification.

Q: Are packaging differences significant for component selection?

A: Packaging format (Bulk versus Bag) affects handling, storage, and inventory management but does not impact electrical or mechanical performance. Selection should consider procurement workflow, storage conditions, and quantity requirements.
