MS3116F14-12P Equivalent & Substitute Parts

Part Overview

The MS3116F14-12P is a 12-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 MS3116F14-12P is discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain system compatibility, ensure procurement continuity, and support field maintenance and system upgrades where original components are no longer readily available through primary distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MS3116F14-12P must satisfy the following critical parameters to ensure functional and mechanical compatibility:

• Connector Type & Position Count: Plug configuration with 12 positions is mandatory for mating with existing receptacles
• Shell Size (14-12): Physical envelope and insert dimensions must match to ensure proper coupling and alignment
• Fastening Mechanism: Bayonet lock coupling is required for secure connection in the intended application environment
• Termination Method: Solder cup termination allows direct wire attachment without additional crimp contacts
• Operating Temperature: -55°C to 125°C range accommodates military and aerospace environmental specifications
• Ingress Protection: Environment resistant rating ensures reliability in harsh operational conditions
• Mounting Configuration: Free hanging (in-line) orientation supports cable-mounted deployment

The substitute parts identified below meet these core compatibility criteria. Variations in shell finish, contact plating, and current/voltage ratings are permissible where the application does not impose specific electrical or environmental constraints beyond the parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

MS3116F14-12P (ITT Cannon, LLC) is the primary substitute for the discontinued Amphenol MS3116F14-12P. Both parts share identical part numbering, connector configuration, and solder cup termination. The ITT Cannon variant is currently active in production, ensuring procurement availability. Contact finish (gold), shell material (aluminum alloy), and operating temperature range (-55°C to 125°C) are equivalent. Specified current ratings (7.5A, 13A) and voltage ratings (600VAC, 850VDC) exceed typical military circular connector requirements. RoHS non-compliance status matches the original part, maintaining consistency with legacy system designs.

MSW06E14-12P-SR (Milspecwest, LLC) provides an alternative substitute where gold contact finish is not a system requirement. This part maintains all critical mechanical and environmental parameters: 12-position configuration, 14-12 shell size, bayonet lock fastening, and -55°C to 125°C operating range. The primary difference is cadmium contact finish instead of gold, which may affect corrosion resistance in specific high-humidity or salt-spray environments. Termination is specified as "solder" rather than "solder cup," requiring verification of wire attachment compatibility with existing assembly procedures. Current and voltage ratings (7.5A/13A, 800V) are specified and suitable for military applications. This part is currently active and available in higher inventory (1057 pcs).

Selection between these substitutes depends on contact finish requirements, termination method compatibility, and procurement lead time constraints.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E14-12P-SR replace the MS3116F14-12P in all applications?

A: The MSW06E14-12P-SR meets all critical mechanical and environmental compatibility parameters. The primary difference is cadmium contact finish versus gold. Applications requiring gold plating for superior corrosion resistance or specific electrical contact characteristics should use the ITT Cannon MS3116F14-12P substitute instead. Termination method ("solder" vs. "solder cup") must be verified against existing assembly procedures.

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

A: Solder cup termination features a cup-shaped contact designed for direct wire insertion and solder attachment. The distinction between "solder" and "solder cup" in the MSW06E14-12P-SR specification requires clarification from the manufacturer to ensure compatibility with existing wire attachment procedures and assembly equipment.

Q: Are all three parts interchangeable in military applications?

A: All three parts conform to MIL-DTL-26482 Series I specifications and operate across the required -55°C to 125°C temperature range. The ITT Cannon MS3116F14-12P is the direct equivalent. The Milspecwest MSW06E14-12P-SR is functionally compatible but differs in contact finish. System design specifications must confirm whether contact finish, current rating, or voltage rating impose constraints on part selection.

Q: Why is the original Amphenol MS3116F14-12P discontinued?

A: Discontinuation at DiGi Electronics reflects distribution decisions rather than product obsolescence. The part remains available through alternative suppliers and equivalent manufacturers. Active production by ITT Cannon and Milspecwest ensures continued availability of compatible 12-position, 14-12 shell size circular connectors with bayonet lock fastening.

Q: What inventory is available for each substitute?

A: ITT Cannon MS3116F14-12P: 696 pcs. Milspecwest MSW06E14-12P-SR: 1057 pcs. Inventory levels support immediate procurement for both substitutes.

Q: Do all parts meet the same environmental and compliance standards?

A: All three parts are RoHS non-compliant and rated for environment-resistant applications. The ITT Cannon part is REACH Affected. The Milspecwest part lists REACH Status as Vendor Undefined. Compliance verification against specific program requirements (ITAR, EAR, ECCN) is necessary for defense and aerospace applications.
