Key Parameters

Substitute Part Grouping Explanation

Substitution for the MS3112E8-3P is determined by strict alignment of the following critical parameters:

• Connector type and pin configuration (Receptacle, Male Pins)
• Position count (3 positions)
• Shell size designation (8-3)
• Mounting configuration (Panel Mount with Flange)
• Termination method (Solder Cup)
• Fastening mechanism (Bayonet Lock)
• Shell material (Aluminum)
• Operating temperature range (-55°C ~ 125°C)
• Environmental protection rating (Environment Resistant)

The MSW02E8-3P from Milspecwest, LLC meets all these criteria and qualifies as a direct substitute. Both connectors conform to MIL-DTL-26482 series specifications and maintain compatibility across military and aerospace applications.

Parameter Comparison

Engineering Selection Recommendations

The MSW02E8-3P is the qualified substitute for the MS3112E8-3P. Both connectors are RoHS non-compliant and classified under ECCN EAR99. The MSW02E8-3P maintains active product status, ensuring continued availability for procurement and support, whereas the original MS3112E8-3P is discontinued. The MSW02E8-3P provides specified electrical ratings (7.5A current, 800V voltage) not documented for the original part, offering additional design margin for electrical applications. Both parts conform to MIL-DTL-26482 series specifications and are suitable for military and aerospace environments.

Frequently Asked Questions (FAQ)

Q: Can MSW02E8-3P directly replace MS3112E8-3P in existing designs?

A: Yes. Both connectors share identical mechanical and functional specifications: 3-position receptacle with male pins, 8-3 shell size, solder cup termination, bayonet lock fastening, panel mount configuration, and -55°C to 125°C operating range. They are mechanically and electrically interchangeable.

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

A: The MS3112E8-3P features Olive Drab Chromate over Cadmium finish, while the MSW02E8-3P uses Cadmium finish. Both provide corrosion resistance suitable for military applications.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS non-compliant and classified as EAR99. No compliance advantage exists between the two options.

Q: Why is the MSW02E8-3P preferred for new designs?

A: The MSW02E8-3P maintains active product status with documented availability, whereas the MS3112E8-3P is discontinued. The MSW02E8-3P also provides specified electrical ratings (7.5A, 800V) for design verification purposes.

Q: Are these connectors suitable for aerospace applications?

A: Yes. Both connectors are designed for aerospace, military, communication systems, and industrial instrumentation applications, with operating temperatures spanning -55°C to 125°C.
