Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3116F22-55S is determined by strict equivalence across the following critical parameters:

• Connector Configuration: Plug type with female sockets
• Position Count: 55 positions
• Shell Size Compatibility: 22-55 insert size
• Mounting Orientation: Free hanging, in-line configuration
• Fastening Mechanism: Bayonet lock coupling
• Electrical Performance: Minimum 7.5A current rating and voltage compatibility
• Environmental Sealing: Environment resistant classification
• Mechanical Features: Strain relief provision
• Operating Temperature: -55°C to 125°C range

The MSW06E22-55S-SR meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the MS3116F22-55S and MSW06E22-55S-SR are active production parts classified under EAR99 export control. Selection between these parts should be based on:

Availability and Lead Time: The MSW06E22-55S-SR currently has 887 units in stock compared to 697 units for the MS3116F22-55S, providing greater inventory availability.

Compliance Status: Both parts are RoHS non-compliant and carry REACH Affected or Vendor Undefined status. Applications requiring specific compliance certifications must verify regulatory requirements independently.

Packaging Consideration: The MS3116F22-55S is supplied in bulk packaging, while the MSW06E22-55S-SR is supplied in bag packaging. Procurement workflows may have specific packaging requirements.

Voltage Rating Specification: The MS3116F22-55S specifies dual voltage ratings (600VAC, 850VDC), while the MSW06E22-55S-SR specifies 800V. Applications requiring specific voltage compliance should confirm compatibility with system requirements.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E22-55S-SR directly replace the MS3116F22-55S in existing assemblies?

A: Yes, provided the application requirements align with the specified electrical and mechanical parameters. Both connectors share identical position count (55), shell size (22-55), mounting type (free hanging), fastening mechanism (bayonet lock), current rating (7.5A), and operating temperature range (-55°C to 125°C).

Q: What is the difference between "Solder Cup" and "Solder" termination?

A: Both termination types are solder-based connection methods. The specific termination geometry and cup design may differ between manufacturers. Component-level compatibility should be confirmed against PCB or cable assembly specifications.

Q: Are there any environmental or compliance differences between these parts?

A: Both parts are classified as environment resistant and carry identical ECCN (EAR99) export control designations. Both are RoHS non-compliant. REACH status differs: MS3116F22-55S is REACH Affected, while MSW06E22-55S-SR is Vendor Undefined. Applications subject to REACH regulations should verify compliance requirements with the respective manufacturers.

Q: Which part should be selected for new designs?

A: Selection should be based on availability, packaging requirements, and specific voltage rating needs. Both parts meet the core functional and environmental requirements for 55-position circular connector applications operating within the -55°C to 125°C temperature range.

Q: What is the significance of the shell size designation "22-55"?

A: This designation indicates the connector shell size and position count. The "22" refers to the shell size class, and "55" confirms the 55-position configuration. This parameter is critical for mechanical fit and mating compatibility.
