MS3114E8-2P Equivalent & Substitute Parts

Part Overview

The MS3114E8-2P is a 2-position circular connector receptacle manufactured by Amphenol Industrial Operations, conforming to MIL-DTL-26482 Series I specifications. This connector features male pins with solder cup termination, panel mount bulkhead installation, and bayonet lock fastening. The part is actively produced and maintained in inventory (1063 pcs available), making it suitable for aerospace, military, communication systems, and industrial applications requiring reliable circular connector solutions in harsh environments.

Equivalent and substitute parts are necessary when original inventory is unavailable, when supply chain optimization is required, or when alternative manufacturers offer compatible solutions meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3114E8-2P is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 2
• Shell Size - Insert: 8-2
• Fastening Type: Bayonet Lock
• Mounting Type: Panel Mount with Bulkhead - Front Side Nut
• Operating Temperature Range: -55°C to 125°C minimum
• Current Rating: 7.5A minimum
• Voltage Rating: 600VAC minimum
• Ingress Protection: Environment Resistant

Acceptable Variations:

• Manufacturer (alternative qualified suppliers)
• Shell finish (alternative corrosion-resistant coatings)
• Contact finish (alternative precious metal plating meeting electrical requirements)
• Termination method (solder cup or equivalent solder termination)
• Series designation (alternative MIL-DTL-26482 compliant designs)

The MSW07E8-2P from Milspecwest, LLC qualifies as a substitute based on matching all mandatory parameters while offering alternative manufacturing and finish specifications.

Parameter Comparison

Engineering Selection Recommendations

MS3114E8-2P (Amphenol Industrial Operations):

• Primary choice for applications requiring Amphenol qualification or established supply chain integration
• Active product status with confirmed inventory (1063 pcs)
• Gold contact finish provides superior corrosion resistance and contact reliability
• Olive Drab Chromate over Cadmium finish meets military environmental specifications
• Moisture Sensitivity Level 1 (Unlimited) indicates robust handling characteristics

MSW07E8-2P (Milspecwest, LLC):

• Qualified alternative when Amphenol supply is constrained
• Meets all mandatory electrical and mechanical parameters
• Voltage rating of 800V exceeds MS3114E8-2P specification, providing design margin
• Cadmium finish and cadmium contact finish meet military corrosion resistance requirements
• RoHS non-compliant status requires verification against program requirements
• REACH Status listed as Vendor Undefined requires clarification before procurement

Both parts conform to MIL-DTL-26482 specifications and are suitable for military, aerospace, and industrial applications. Selection should be based on supply availability, program compliance requirements, and established vendor qualification status.

Frequently Asked Questions (FAQ)

Q: Can MSW07E8-2P directly replace MS3114E8-2P in existing assemblies?

A: Yes, provided that RoHS compliance is not a program requirement. The MSW07E8-2P meets all mandatory electrical and mechanical parameters. However, the cadmium finish differs from the Amphenol olive drab chromate specification. Verify finish compatibility with your application environment and program specifications before implementation.

Q: What is the difference between "Receptacle, Male Pins" and "Plug, Male Pins"?

A: Both designations refer to connector halves with male pin contacts. The terminology difference reflects manufacturer classification conventions. Both are functionally equivalent for mating with corresponding female contact connectors and are interchangeable in applications requiring 2-position, 8-2 shell size bayonet-lock circular connectors.

Q: Are there electrical performance differences between the two parts?

A: Both parts are rated for 7.5A current and operate across -55°C to 125°C. The MSW07E8-2P has a higher voltage rating (800V vs. 600VAC), which provides additional design margin but does not affect compatibility. Contact finish differences (gold vs. cadmium) may affect contact resistance and corrosion resistance in specific environments; verify against your application requirements.

Q: What compliance issues should I consider?

A: Both parts carry EAR99 ECCN classification. The MS3114E8-2P has defined RoHS non-compliance status. The MSW07E8-2P lists REACH Status as Vendor Undefined, requiring clarification from Milspecwest before use in programs with REACH compliance requirements. Verify all compliance requirements with your program documentation.

Q: How do I verify part authenticity when sourcing MSW07E8-2P?

A: Obtain parts directly from Milspecwest, LLC or authorized distributors. Request certificates of conformance (CoC) and traceability documentation. Verify part markings match the specification sheet. Confirm ECCN and compliance documentation with the supplier before procurement.

Q: Can I mix MS3114E8-2P and MSW07E8-2P in the same assembly?

A: Yes, both parts meet identical functional requirements and can be used in the same assembly. However, document the substitution in your bill of materials and configuration management records. Ensure your quality assurance process approves mixed-source components for your specific application.
