Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3114E8-4P is determined by the following critical parameters:

• Connector Type & Pin Configuration: Receptacle with male pins, 4-position configuration
• Shell Size & Insert: 8-4 designation for mechanical compatibility
• Mounting Interface: Panel mount with bulkhead front side nut fastening
• Fastening Mechanism: Bayonet lock coupling
• Termination Method: Solder cup or equivalent solder termination
• Operating Temperature: -55°C ~ 125°C range
• Series Compliance: MIL-DTL-26482 style connectors
• Material & Finish: Aluminum shell with corrosion-resistant finish

The MSW07E8-4P qualifies as a substitute based on matching shell size (8-4), 4-position configuration, bayonet lock fastening, panel mount bulkhead design, and identical operating temperature range. Both parts comply with MIL-DTL-26482 series specifications and maintain environmental resistance suitable for military and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

The MSW07E8-4P is an active substitute for the discontinued MS3114E8-4P. Both parts maintain MIL-DTL-26482 series compliance and share identical mechanical interfaces, shell sizes, and operating temperature specifications. The MSW07E8-4P is currently in active production status with 1003 units available in inventory, providing supply continuity for applications requiring 4-position circular connectors with bayonet lock fastening.

Both parts carry EAR99 export classification and are RoHS non-compliant, consistent with military-grade connector specifications. The substitute maintains the same environmental resistance rating and operating temperature range required for aerospace, military, and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the MSW07E8-4P directly replace the MS3114E8-4P in existing assemblies?

A: The MSW07E8-4P matches the critical mechanical and electrical parameters: 4-position configuration, 8-4 shell size, bayonet lock fastening, panel mount bulkhead design, and -55°C ~ 125°C operating temperature. Both parts comply with MIL-DTL-26482 series specifications. Verification of specific application requirements is necessary before implementation.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Amphenol vs. Milspecwest), connector type designation (receptacle vs. plug), contact finish (gold vs. cadmium), and termination specification (solder cup vs. solder). The shell size, position count, fastening mechanism, and operating temperature range are identical.

Q: Why is the MS3114E8-4P discontinued?

A: The MS3114E8-4P is discontinued at DiGi Electronics. The MSW07E8-4P remains in active production and provides equivalent functionality for ongoing procurement requirements.

Q: Are there any compliance or certification differences?

A: Both parts carry EAR99 export classification and are RoHS non-compliant. Both maintain environmental resistance ratings suitable for military and industrial applications. No compliance differences exist between the two parts.

Q: What is the inventory status of the substitute?

A: The MSW07E8-4P has 1003 units available in new original stock, providing immediate availability for procurement.
