Key Parameters

Substitute Part Grouping Explanation

Substitution for the MS3112E22-55P is based on the following critical parameters that must remain constant:

• Connector Type & Pin Configuration: Receptacle with male pins (55 positions)
• Shell Size: 22-55 insert designation
• Mounting Configuration: Panel mount with flange
• Termination Method: Solder cup
• Fastening Mechanism: Bayonet lock
• Environmental Rating: Environment resistant classification
• Operating Temperature Range: -55°C to 125°C
• Shell Material: Aluminum construction

The MSW02E22-55P from Milspecwest, LLC meets all these core substitution criteria, maintaining mechanical and electrical compatibility with the original MS3112E22-55P specification.

Parameter Comparison

Engineering Selection Recommendations

The MSW02E22-55P serves as a direct functional equivalent to the MS3112E22-55P. Both connectors share identical mechanical specifications, pin configuration, and environmental operating parameters. The MSW02E22-55P is currently in active production status, providing supply continuity for applications previously using the discontinued Amphenol part.

Both parts maintain RoHS non-compliant status, consistent with military-grade circular connector specifications. The MSW02E22-55P provides specified electrical ratings (7.5A at 800V), whereas the original part does not document these parameters. For applications requiring electrical performance verification, the MSW02E22-55P specifications establish the operational envelope for this connector class.

Frequently Asked Questions (FAQ)

Q: Can the MSW02E22-55P directly replace the MS3112E22-55P in existing assemblies?

A: Yes. Both connectors maintain identical mechanical interfaces, pin counts, mounting configurations, and environmental ratings. The MSW02E22-55P is mechanically and functionally interchangeable with the MS3112E22-55P.

Q: What are the key compatibility factors for this connector substitution?

A: Compatibility is determined by: 55-position pin count, 22-55 shell size, panel mount flange configuration, bayonet lock fastening, solder cup termination, and -55°C to 125°C operating temperature range. Both parts meet these requirements.

Q: Does the MSW02E22-55P provide electrical specifications that the original part does not?

A: The MSW02E22-55P specifies 7.5A current rating and 800V voltage rating. The original MS3112E22-55P does not document these electrical parameters. For applications requiring electrical performance data, the MSW02E22-55P specifications apply to this connector class.

Q: Are there packaging differences between these parts?

A: The MS3112E22-55P is supplied in bulk packaging, while the MSW02E22-55P is supplied in bag packaging. This difference does not affect connector performance or compatibility.

Q: What is the compliance status of the MSW02E22-55P?

A: The MSW02E22-55P is RoHS non-compliant and REACH status is vendor undefined. It maintains EAR99 export classification consistent with military connector specifications.
