MS3116F8-2P Equivalent & Substitute Parts

Part Overview

The MS3116F8-2P is a 2-position circular connector plug with male pins manufactured by Amphenol Industrial Operations. This connector is part of the Military MIL-DTL-26482 Series I product line and features solder cup termination with bayonet lock fastening. The part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing system maintenance and new production requirements. The connector is designed for aerospace, communication systems, industrial, instrumentation, mass transit, and military applications requiring environmental resistance and reliable mating in harsh operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MS3116F8-2P is determined by strict adherence to the following critical parameters:

• Connector Type & Gender: Plug with male pins (fixed requirement)
• Position Count: 2 positions (fixed requirement)
• Shell Size: 8-2 insert designation (fixed requirement)
• Fastening Mechanism: Bayonet lock coupling (fixed requirement)
• Mounting Configuration: Free hanging in-line (fixed requirement)
• Operating Temperature: -55°C ~ 125°C (fixed requirement)
• Ingress Protection: Environment resistant capability (fixed requirement)
• Series Compliance: MIL-DTL-26482 style connectors (fixed requirement)

The substitute part MSW06E8-2P-SR meets all critical parameters for direct substitution. While termination method differs (solder vs. solder cup), both are solder-based termination approaches suitable for equivalent circuit integration. Differences in contact finish material and shell finish do not preclude functional equivalence when electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E8-2P-SR is a direct functional equivalent to the MS3116F8-2P based on matching mechanical interface parameters, connector geometry, and environmental operating specifications. The substitute part is currently in active production status, addressing the discontinuation of the original part.

Both parts are RoHS non-compliant and carry identical ECCN classification (EAR99), maintaining regulatory consistency for military and aerospace applications. The substitute part provides documented electrical ratings (7.5A at 800V), which the original part specification does not include but does not contradict.

The primary difference is termination method: the original uses solder cup termination while the substitute uses solder termination with strain relief. Both are solder-based approaches suitable for equivalent circuit integration when PCB layout and wire gauge requirements are accommodated.

Selection of the MSW06E8-2P-SR is appropriate for applications requiring the MS3116F8-2P where part availability is a constraint and mechanical and environmental interface requirements are the primary design drivers.

Frequently Asked Questions (FAQ)

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

A: Yes, for mechanical and environmental interface requirements. Both connectors share identical shell size (8-2), position count (2), fastening mechanism (bayonet lock), mounting configuration (free hanging in-line), and operating temperature range (-55°C ~ 125°C). Termination method differs (solder cup vs. solder), requiring verification that PCB pad design and wire termination procedures are compatible with the substitute part's solder termination approach.

Q: Are there electrical rating differences between these parts?

A: The original MS3116F8-2P does not specify current or voltage ratings in the provided documentation. The substitute MSW06E8-2P-SR is rated for 7.5A at 800V. Verify that your application requirements do not exceed these electrical parameters.

Q: Do both parts meet the same environmental specifications?

A: Yes. Both connectors are rated for environment resistant ingress protection and operate across the identical temperature range of -55°C ~ 125°C, suitable for aerospace, military, and industrial applications.

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

A: Solder cup termination uses a cup-shaped contact designed for wire insertion and solder flow. Solder termination with strain relief uses a different contact geometry optimized for direct solder attachment. Both are solder-based methods; PCB layout and wire preparation procedures must be adjusted accordingly for the substitute part.

Q: Are compliance certifications equivalent?

A: Both parts carry RoHS non-compliant status and identical ECCN classification (EAR99). Regulatory compliance for your specific application should be verified independently based on end-use requirements.
