Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3116F14-18P is determined by the following critical parameters:

• Connector Type & Pin Configuration: Must be Plug with Male Pins, 18-position configuration
• Shell Size: Must match 14-18 insert size for mechanical compatibility
• Fastening Mechanism: Must use Bayonet Lock coupling
• Mounting Configuration: Must support Free Hanging (In-Line) installation
• Shell Material: Aluminum construction required
• Operating Temperature Range: Must support -55°C ~ 125°C minimum
• Ingress Protection: Must provide Environment Resistant rating
• Series Compliance: Must conform to MIL-DTL-26482 or equivalent military circular connector standards

The MSW06E14-18P-SR qualifies as a substitute based on matching all critical parameters. While termination differs (Solder vs. Solder Cup), both are solder-based termination methods compatible with the same contact interface. Contact finish variation (Cadmium vs. Gold) represents a material downgrade but remains within acceptable military connector specifications.

Parameter Comparison

Engineering Selection Recommendations

The MSW06E14-18P-SR is a qualified substitute for the discontinued MS3116F14-18P based on the following engineering criteria:

Mechanical Compatibility: Both connectors share identical shell size (14-18), bayonet-lock fastening, and free-hanging mounting configuration, ensuring direct mechanical interchangeability in existing installations.

Electrical Performance: The MSW06E14-18P-SR provides specified electrical ratings (800V, 7.5A/13A) that exceed typical military circular connector requirements. The original MS3116F14-18P does not specify electrical ratings in available documentation.

Environmental Specifications: Both connectors maintain the required -55°C ~ 125°C operating temperature range and environment-resistant ingress protection, meeting aerospace and military application demands.

Compliance Status: Both parts are RoHS non-compliant and carry EAR99 ECCN classification, maintaining regulatory consistency with the original design.

Contact Finish Consideration: The MSW06E14-18P-SR uses cadmium contact finish versus the gold finish of the MS3116F14-18P. Cadmium finish is acceptable for military applications per MIL-DTL-26482 specifications, though gold provides superior corrosion resistance in high-reliability applications.

Product Availability: The MSW06E14-18P-SR is currently active in production with 1093 units in stock, ensuring supply continuity for ongoing requirements.

Frequently Asked Questions (FAQ)

Q: Can the MSW06E14-18P-SR directly replace the MS3116F14-18P in existing assemblies?

A: Yes. Both connectors share identical shell size (14-18), 18-position configuration, bayonet-lock coupling, and free-hanging mounting. Physical and mechanical interchangeability is confirmed. Electrical performance of the MSW06E14-18P-SR meets or exceeds typical application requirements.

Q: What is the difference between Solder Cup and Solder termination?

A: Both are solder-based termination methods. Solder Cup provides a cup-shaped contact receptacle for wire insertion and solder flow. Solder termination uses a flat or formed contact surface for solder attachment. Both methods create equivalent electrical connections when properly executed.

Q: Does the cadmium contact finish of the MSW06E14-18P-SR affect performance compared to the gold finish of the MS3116F14-18P?

A: Cadmium finish is specified in MIL-DTL-26482 military connector standards and provides adequate corrosion resistance for most military and industrial applications. Gold finish offers superior corrosion resistance in high-humidity or corrosive environments. Selection depends on specific application environmental requirements.

Q: Are both connectors RoHS compliant?

A: No. Both the MS3116F14-18P and MSW06E14-18P-SR are RoHS non-compliant. This is typical for military-grade circular connectors using cadmium and other materials required for MIL-DTL-26482 compliance.

Q: What is the packaging difference between these connectors?

A: The MS3116F14-18P packaging is not specified in available data. The MSW06E14-18P-SR is supplied in Bag packaging. Packaging does not affect connector functionality or interchangeability.

Q: Can I use the MSW06E14-18P-SR in aerospace applications?

A: The MSW06E14-18P-SR is specified for military applications and conforms to 26482 Style Connector standards. Aerospace application approval depends on specific program requirements and qualification documentation. Consult applicable aerospace standards and program specifications before implementation.
