Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3114F8-4P is determined by the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 4 positions is mandatory for mechanical and electrical compatibility
• Shell Size - Insert: Size 8-4 designation ensures physical fit within existing panel cutouts and mating interfaces
• Mounting Configuration: Panel mount with bulkhead front-side nut mounting must be preserved for installation compatibility
• Fastening Mechanism: Bayonet lock fastening type is required for proper connector engagement and retention
• Operating Temperature Range: -55°C ~ 125°C operational envelope must be maintained or exceeded
• Series Compliance: MIL-DTL-26482 Series I compatibility ensures electrical and mechanical standardization
• Termination Method: Solder termination is acceptable for equivalent substitution

The substitute part MSW07E8-4P-SR meets these critical parameters while offering active product status and enhanced strain relief features.

Parameter Comparison

Engineering Selection Recommendations

The MSW07E8-4P-SR qualifies as a functional equivalent to the MS3114F8-4P based on matching critical parameters: identical shell size (8-4), position count (4), mounting configuration (panel mount bulkhead), fastening type (bayonet lock), and operating temperature range (-55°C ~ 125°C). Both connectors comply with MIL-DTL-26482 series specifications and maintain RoHS non-compliant status consistent with military applications.

The primary distinction is product status: the MS3114F8-4P is discontinued, while the MSW07E8-4P-SR maintains active availability. The substitute part provides specified electrical ratings (7.5A current, 800V voltage) and includes strain relief features not detailed in the original part specification. Both parts are non-compliant with RoHS requirements, maintaining compatibility with legacy military and aerospace systems where RoHS exemptions apply.

Frequently Asked Questions (FAQ)

Q: Can MSW07E8-4P-SR directly replace MS3114F8-4P in existing assemblies?

A: Yes. Both connectors share identical shell size (8-4), position count (4), mounting configuration (panel mount bulkhead front-side nut), fastening type (bayonet lock), and operating temperature range (-55°C ~ 125°C). Mechanical and electrical interfaces are compatible.

Q: What is the difference between receptacle and plug connector types?

A: The MS3114F8-4P is a receptacle with male pins (receives mating connector). The MSW07E8-4P-SR is a plug with male pins (mates into receptacle). In a complete connector pair, one receptacle and one plug are required. Verify your application requires a receptacle configuration.

Q: Are there differences in contact finish between these parts?

A: The MS3114F8-4P specifies gold contact finish for mating surfaces. The MSW07E8-4P-SR specifies cadmium contact finish. Both finishes are acceptable for MIL-DTL-26482 series applications. Contact finish selection depends on specific system requirements for corrosion resistance and electrical performance.

Q: Why is the shell finish different?

A: The MS3114F8-4P uses olive drab chromate over cadmium finish. The MSW07E8-4P-SR uses cadmium finish. Both provide corrosion protection suitable for military and aerospace environments. Finish selection may depend on specific environmental exposure requirements and system specifications.

Q: What does "26482 Style Connectors" mean for the substitute part?

A: This designation indicates the MSW07E8-4P-SR conforms to MIL-DTL-26482 series specifications, ensuring compatibility with systems designed for this military connector standard. The substitute part maintains the same electrical and mechanical interface standards as the original MS3114F8-4P.

Q: Are both parts suitable for the same applications?

A: Both connectors are rated for military applications and share identical operating temperature range (-55°C ~ 125°C). The MSW07E8-4P-SR provides specified electrical ratings (7.5A, 800V) and strain relief features. Verify application-specific requirements for electrical load and environmental conditions.
