MS3116F20-41P Equivalent & Substitute Parts

Part Overview

The MS3116F20-41P is a 41-position circular connector plug manufactured by ITT Cannon, LLC, featuring male pins with solder cup termination. This connector is designed for free-hanging, in-line applications requiring bayonet lock fastening and environmental resistance. The part is currently active in production with 1052 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained, enabling procurement flexibility and supply chain continuity for applications where the original part may have extended lead times or availability constraints.

Substitute Part Grouping Explanation

Substitution eligibility for the MS3116F20-41P is determined by strict equivalence across the following critical parameters:

Connector Type & Gender: Plug with male pins (maintains mating compatibility)
Position Count: 41 positions (ensures pin-to-pin correspondence)
Shell Size Designation: 20-41 (guarantees mechanical fit and interface compatibility)
Fastening Mechanism: Bayonet lock (ensures secure coupling with mating receptacles)
Termination Method: Solder or solder cup (allows equivalent assembly and rework procedures)
Current & Voltage Ratings: Minimum 7.5A and voltage tolerance of 600VAC/850VDC or higher
Operating Temperature: -55°C to 125°C or equivalent range
Environmental Resistance: Required for equivalent field performance

The substitute part MSW06E20-41P-SR meets all these criteria and is therefore classified as a direct equivalent for the MS3116F20-41P.

Engineering Selection Recommendations

Both the MS3116F20-41P and MSW06E20-41P-SR are active production parts suitable for military and aerospace applications. Selection between these parts should be based on the following factors:

MS3116F20-41P (ITT Cannon, LLC): This part carries full RoHS non-compliance status and REACH affected designation. It features gold contact finish at 50.0µin (1.27µm) thickness, providing enhanced corrosion resistance and contact reliability. Olive drab cadmium shell finish is specified. Current inventory is 1052 units.

MSW06E20-41P-SR (Milspecwest, LLC): This part is classified as RoHS non-compliant with vendor-undefined REACH status. It features cadmium contact finish and cadmium shell finish. The series designation (26482 Style Connectors) indicates compatibility with established military connector standards. Current inventory is 1147 units.

Both parts share equivalent electrical performance, mechanical interface, and environmental ratings. The choice between them depends on specific compliance requirements, contact finish specifications, and supply chain preferences. Both are suitable for direct substitution in applications where the MS3116F20-41P is specified.

Frequently Asked Questions (FAQ)

Q: Can MSW06E20-41P-SR be used as a direct replacement for MS3116F20-41P?

A: Yes. Both connectors share identical position count (41), shell size (20-41), fastening type (bayonet lock), current rating (7.5A), voltage rating (800V or higher), operating temperature range (-55°C to 125°C), and environmental resistance. The termination methods (solder cup vs. solder) are functionally equivalent for assembly purposes.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer identity, contact finish specification (gold vs. cadmium), shell finish (olive drab cadmium vs. cadmium), packaging format (bulk vs. bag), and compliance documentation status. Electrical and mechanical performance parameters are equivalent.

Q: Are there any packaging considerations when substituting these parts?

A: The MS3116F20-41P is supplied in bulk packaging, while the MSW06E20-41P-SR is supplied in bag packaging. This difference does not affect connector performance but may impact receiving, storage, and handling procedures. Verify packaging requirements with your procurement and logistics departments.

Q: Do both parts meet military specifications?

A: Both parts are classified as active production components suitable for military applications. The MSW06E20-41P-SR is explicitly designated for military use. Both carry EAR99 ECCN classification. Verify specific military standard compliance requirements with your engineering documentation.

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

A: The MS3116F20-41P features gold contact finish (50.0µin thickness), which provides superior corrosion resistance and contact reliability in harsh environments. The MSW06E20-41P-SR features cadmium contact finish. Selection should be based on your application's environmental exposure and contact reliability requirements.
