Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3116F8-2P is determined by the following critical parameters:

• Connector Type & Gender: Must be Plug with Male Pins
• Position Count: Must be 2-position configuration
• Shell Size: Must be 8-2 (ensures mechanical fit with mating receptacles)
• Fastening Mechanism: Must be Bayonet Lock (ensures proper coupling)
• Termination Method: Must be Solder or Solder Cup (ensures electrical connection compatibility)
• Current & Voltage Ratings: Must meet or exceed 7.5A and 600VAC/850VDC specifications
• Operating Temperature Range: Must support -55°C ~ 125°C
• Environmental Rating: Must provide Environment Resistant protection
• Mounting Configuration: Must be Free Hanging (In-Line)

The MSW06E8-2P-SR from Milspecwest, LLC meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the MS3116F8-2P and MSW06E8-2P-SR are active production parts with equivalent electrical and mechanical specifications. Selection between these parts should be based on:

Compliance Considerations: The MS3116F8-2P is RoHS non-compliant and REACH Affected. The MSW06E8-2P-SR is RoHS non-compliant with Vendor Undefined REACH status. Both parts carry EAR99 ECCN classification.

Availability: The MSW06E8-2P-SR currently has higher inventory availability (941 units) compared to the MS3116F8-2P (738 units).

Contact Finish: The MS3116F8-2P features gold mating contact finish (50.0µin thickness), while the MSW06E8-2P-SR uses cadmium contact finish. This difference may affect corrosion resistance in specific environmental applications.

Shell Material & Finish: Both use aluminum alloy shells with cadmium finish, providing equivalent environmental protection.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E8-2P-SR directly replace the MS3116F8-2P in existing designs?

A: Yes, the MSW06E8-2P-SR is mechanically and electrically compatible. Both connectors share identical shell size (8-2), fastening type (bayonet lock), position count (2), and current/voltage ratings. The primary difference is contact finish material (gold vs. cadmium), which should be evaluated based on your specific environmental and corrosion requirements.

Q: What is the significance of the shell size 8-2 designation?

A: Shell size 8-2 is a standardized MIL specification that ensures mechanical compatibility with mating receptacles of the same designation. Both the MS3116F8-2P and MSW06E8-2P-SR conform to this standard, guaranteeing proper fit and coupling.

Q: Are there differences in termination methods between these parts?

A: The MS3116F8-2P uses solder cup termination, while the MSW06E8-2P-SR uses solder termination. Both methods provide equivalent electrical connections for cable assembly applications. Solder cup termination typically offers a slightly larger contact area, but both are suitable for the specified current and voltage ratings.

Q: Do both parts meet the same environmental and temperature specifications?

A: Yes. Both connectors are rated for -55°C to 125°C operating temperature and provide environment-resistant protection. Both are suitable for military and harsh environment applications.

Q: What compliance differences should I consider?

A: Both parts are RoHS non-compliant and carry EAR99 ECCN classification. The MS3116F8-2P is REACH Affected, while the MSW06E8-2P-SR has Vendor Undefined REACH status. Verify compliance requirements with your procurement and regulatory teams before final selection.
