MS3116E8-4P Equivalent & Substitute Parts

Part Overview

The MS3116E8-4P is a 4-position circular connector plug with male pins and solder cup termination, manufactured by Amphenol Industrial Operations. This connector conforms to MIL-DTL-26482 Series I specifications and is designed for aerospace, military, communication systems, and industrial applications requiring environmental resistance and reliable bayonet-lock coupling.

The MS3116E8-4P is discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for repair, maintenance, and new production applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS3116E8-4P is determined by the following critical parameters that must match or be compatible:

• Connector Type & Gender: Plug with male pins (maintains mating interface compatibility)
• Position Count: 4 positions (electrical interface requirement)
• Shell Size - Insert: 8-4 (mechanical fit and bayonet coupling compatibility)
• Fastening Type: Bayonet Lock (mechanical coupling method)
• Mounting Type: Free Hanging (In-Line) (installation configuration)
• Operating Temperature Range: -55°C ~ 125°C (environmental operating envelope)
• Ingress Protection: Environment Resistant (environmental sealing requirement)
• Series Compliance: MIL-DTL-26482 or equivalent military circular connector standard

The MSW06E8-4P qualifies as a substitute based on these parameters. Termination method variation (solder cup to solder) and contact finish differences (gold to cadmium) are acceptable substitutions within the scope of this connector category, provided the electrical and mechanical interfaces remain compatible.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E8-4P is an active substitute for the discontinued MS3116E8-4P. Both connectors maintain identical mechanical interfaces (shell size 8-4, bayonet fastening, 4-position configuration) and identical operating temperature ranges (-55°C ~ 125°C). Both are MIL-DTL-26482 compliant circular connectors with environment-resistant ingress protection suitable for military and aerospace applications.

The MSW06E8-4P is currently in active production status with 1203 units in stock, ensuring availability for immediate procurement. Both parts carry RoHS non-compliant status and EAR99 export classification, maintaining regulatory consistency.

Differences in shell finish (Olive Drab Chromate over Cadmium versus Cadmium) and contact finish (Gold versus Cadmium) are material variations within the MIL-DTL-26482 standard. These variations do not affect mechanical compatibility or electrical interface performance in applications where the operating temperature range and environmental resistance requirements are met.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E8-4P directly replace the MS3116E8-4P in existing assemblies?

A: Yes. Both connectors share identical shell size (8-4), position count (4), fastening method (bayonet lock), and mounting configuration (free hanging in-line). The mechanical and electrical interfaces are compatible.

Q: What is the difference between solder cup and solder termination?

A: Solder cup termination features a cup-shaped contact designed for wire insertion and solder attachment. Solder termination refers to the general soldering process. Both methods provide equivalent electrical connection when properly executed.

Q: Does the difference in contact finish (gold versus cadmium) affect performance?

A: Both gold and cadmium contact finishes are specified within MIL-DTL-26482 standards. Contact finish selection depends on application-specific corrosion resistance and signal integrity requirements. Cadmium finish is suitable for general military and industrial applications with environment-resistant protection.

Q: Are both connectors suitable for aerospace applications?

A: The MS3116E8-4P is specified for aerospace applications. The MSW06E8-4P is specified for military applications. Both conform to MIL-DTL-26482 standards. Application suitability depends on specific aerospace qualification requirements and procurement specifications.

Q: What is the inventory status for each part?

A: MS3116E8-4P: 908 units in stock (discontinued). MSW06E8-4P: 1203 units in stock (active production).

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS non-compliant and carry EAR99 export classification. Both have HTSUS code 8536.69.4020 (MS3116E8-4P). Regulatory compliance status is equivalent.
