Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3116F22-55P is determined by strict alignment with the following critical parameters:

• Connector type: Plug with male pins
• Position count: 55 positions
• Shell size designation: 22-55
• Fastening mechanism: Bayonet lock
• Mounting configuration: Free hanging (in-line)
• Operating temperature range: -55°C to 125°C minimum
• Environmental resistance capability
• MIL-DTL-26482 series compliance or equivalent military circular connector standard

The MSW06E22-55P-SR qualifies as a substitute based on matching these core parameters. Both connectors share identical position count, shell size, fastening type, mounting configuration, and operating temperature range. Both are designated as 26482 style connectors and provide environment-resistant performance suitable for military applications.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E22-55P-SR is available as an active product with current inventory, whereas the MS3116F22-55P is discontinued. Both connectors are RoHS non-compliant and share identical core mechanical and environmental specifications.

Selection between these parts should be based on:

• Availability requirements: MSW06E22-55P-SR maintains active production status and inventory availability
• Compliance requirements: Both parts are RoHS non-compliant; system compliance obligations remain unchanged regardless of part selection
• Electrical specifications: MSW06E22-55P-SR provides documented current (7.5A) and voltage (800V) ratings; the main part does not specify these values
• Termination method: Both utilize solder termination; assembly procedures remain compatible
• Military application suitability: Both are designated for military applications and conform to MIL-DTL-26482 series standards

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors share identical position count (55), shell size (22-55), fastening type (bayonet lock), mounting configuration (free hanging in-line), and operating temperature range (-55°C to 125°C). Mechanical and electrical interface compatibility is maintained.

Q: What is the difference in contact finish between these connectors?

A: MS3116F22-55P specifies gold contact finish for mating surfaces. MSW06E22-55P-SR specifies cadmium contact finish. This difference may affect contact resistance and corrosion resistance characteristics in specific environmental conditions.

Q: Are both connectors suitable for aerospace applications?

A: MS3116F22-55P is explicitly listed for aerospace applications. MSW06E22-55P-SR is designated for military applications. Aerospace system integration requires verification of specific procurement and qualification requirements for the substitute part.

Q: What is the difference in shell finish?

A: MS3116F22-55P features olive drab chromate over cadmium finish. MSW06E22-55P-SR features cadmium finish. Both provide corrosion resistance suitable for environment-resistant applications.

Q: Are electrical ratings identical?

A: MS3116F22-55P does not specify current or voltage ratings in available documentation. MSW06E22-55P-SR is rated for 7.5A at 800V. System design requirements should be verified against the substitute part's documented electrical specifications.

Q: What packaging differences exist?

A: MS3116F22-55P packaging is not specified. MSW06E22-55P-SR is supplied in bag packaging. Procurement and handling procedures may differ accordingly.
