MS3116F8-3P Equivalent & Substitute Parts

Part Overview

The MS3116F8-3P is a 3-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 bayonet-lock coupling and environmental resistance.

The MS3116F8-3P 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 requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS3116F8-3P is determined by the following critical parameters:

• Connector Type & Gender: Plug with male pins (fixed requirement)
• Position Count: 3 positions (fixed requirement)
• Shell Size: 8-3 insert size (fixed requirement)
• Fastening Mechanism: Bayonet lock coupling (fixed requirement)
• Termination Method: Solder or solder cup (acceptable variation)
• Shell Material & Finish: Aluminum construction with corrosion-resistant finish
• Environmental Rating: Environment resistant classification
• Operating Temperature Range: -55°C ~ 125°C (fixed requirement)
• Mounting Configuration: Free hanging, in-line orientation

The MSW06E8-3P-SR qualifies as a substitute based on matching all critical parameters: identical connector type, position count, shell size, bayonet fastening, aluminum shell construction, environment resistant rating, and operating temperature range. The termination method differs (solder vs. solder cup), which is an acceptable variation for this connector category.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E8-3P-SR is an active substitute for the discontinued MS3116F8-3P. Both connectors maintain identical mechanical and electrical interface specifications for the 3-position, size 8-3 bayonet-lock circular connector format.

Key considerations for selection:

• Product Availability: The MSW06E8-3P-SR is currently in active production with 1192 units in stock, whereas the MS3116F8-3P is discontinued.
• Compliance Status: Both parts are RoHS non-compliant and carry EAR99 ECCN classification, maintaining equivalent regulatory posture.
• Contact Finish Difference: The MS3116F8-3P features gold mating contacts, while the MSW06E8-3P-SR uses cadmium. This difference may affect corrosion resistance and contact resistance characteristics in specific environments.
• Shell Finish Variation: The MS3116F8-3P specifies olive drab chromate over cadmium, while the MSW06E8-3P-SR uses cadmium finish. Both provide corrosion protection suitable for military and industrial applications.
• Termination Method: The MS3116F8-3P uses solder cup termination; the MSW06E8-3P-SR uses solder termination. Both methods are compatible with standard PCB assembly processes.
• Electrical Ratings: The MSW06E8-3P-SR provides specified current (7.5A) and voltage (800V) ratings, whereas the MS3116F8-3P does not list these values in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E8-3P-SR directly replace the MS3116F8-3P in existing assemblies?

A: Yes, the MSW06E8-3P-SR is mechanically and electrically compatible as a substitute. Both connectors share identical shell size (8-3), position count (3), bayonet fastening, and operating temperature range (-55°C ~ 125°C). The primary differences are contact finish (gold vs. cadmium) and shell finish (olive drab chromate vs. cadmium), which may require evaluation based on specific application corrosion and contact resistance requirements.

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 uses a flat or shaped contact surface for direct solder connection. Both methods achieve equivalent electrical and mechanical connections in PCB assembly applications.

Q: Are both connectors suitable for military applications?

A: Yes. The MS3116F8-3P conforms to MIL-DTL-26482 Series I specifications. The MSW06E8-3P-SR is designated as a 26482 Style Connector and is rated for military applications. Both are RoHS non-compliant and carry EAR99 ECCN classification, consistent with military-grade component requirements.

Q: What is the significance of the contact finish difference?

A: The MS3116F8-3P uses gold mating contacts, which provide superior corrosion resistance and lower contact resistance. The MSW06E8-3P-SR uses cadmium contacts, which provide adequate corrosion protection for most military and industrial environments. Selection depends on specific application requirements for contact resistance stability and environmental exposure.

Q: Is the MSW06E8-3P-SR available in the same packaging as the MS3116F8-3P?

A: The MS3116F8-3P packaging is not specified in available documentation. The MSW06E8-3P-SR is supplied in bag packaging. Confirm packaging requirements with your procurement or assembly process specifications.

Q: What are the electrical specifications for the MSW06E8-3P-SR?

A: The MSW06E8-3P-SR is rated for 7.5A current and 800V voltage. The MS3116F8-3P does not list electrical ratings in available documentation. Confirm that these ratings meet your application requirements.
