MS3116F8-33S Equivalent & Substitute Parts

Part Overview

The MS3116F8-33S is a 3-position circular connector plug manufactured by ITT Cannon, LLC, featuring female sockets with solder cup termination. This connector is designed for free-hanging in-line applications requiring bayonet lock fastening and environmental resistance. The part operates across a temperature range of -55°C to 125°C with a current rating of 7.5A and voltage ratings of 600VAC/850VDC. As an active product with established inventory availability, substitute parts may be required due to supply chain considerations, packaging preferences, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3116F8-33S is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Plug with female sockets
• Number of positions: 3
• Shell size - insert: 8-33
• Mounting type: Free hanging (in-line)
• Fastening type: Bayonet lock
• Current rating: 7.5A minimum
• Operating temperature range: -55°C to 125°C minimum
• Ingress protection: Environment resistant

Acceptable Variation Parameters:

• Termination method: Solder cup or solder (both acceptable for wire attachment)
• Shell material: Aluminum alloy or aluminum
• Shell finish: Olive drab cadmium or cadmium
• Contact finish: Gold or cadmium
• Packaging format: Bulk or bag

The MSW06E8-33S-SR qualifies as a substitute part based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

MS3116F8-33S Selection Criteria:

• Primary choice when gold contact finish is required for enhanced corrosion resistance or specific mating surface requirements
• Preferred when olive drab cadmium shell finish is specified for military or aerospace applications
• Suitable for applications where solder cup termination is the established assembly standard
• Available in bulk packaging for high-volume procurement

MSW06E8-33S-SR Selection Criteria:

• Acceptable alternative when cadmium contact finish meets application requirements
• Suitable when bag packaging format is preferred for inventory management
• Equivalent electrical and mechanical performance for applications not requiring gold-plated contacts
• Both parts maintain identical current, voltage, and temperature ratings

Both parts are active products with established supply chains. Selection between them should be based on specific finish requirements, packaging preferences, and established assembly procedures rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can MSW06E8-33S-SR directly replace MS3116F8-33S in existing assemblies?

A: Yes, from an electrical and mechanical standpoint. Both connectors share identical shell size (8-33), position count (3), mounting configuration (free hanging in-line), fastening method (bayonet lock), current rating (7.5A), voltage rating (compatible), and operating temperature range (-55°C to 125°C). The primary difference is contact finish material (gold versus cadmium), which does not affect mechanical fit or basic electrical function.

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

A: The MS3116F8-33S features gold-plated mating contacts, while the MSW06E8-33S-SR uses cadmium finish. Gold provides superior corrosion resistance and lower contact resistance over extended service life. Cadmium finish is acceptable for general military and industrial applications. Selection depends on application-specific requirements for contact reliability and environmental exposure.

Q: Are the termination methods interchangeable?

A: Both solder cup and solder termination methods are compatible for wire attachment. Solder cup termination provides a pre-formed cup for solder joint formation, while solder termination indicates direct solder attachment capability. Both achieve equivalent electrical connections when properly executed.

Q: What packaging differences exist between these parts?

A: MS3116F8-33S is supplied in bulk packaging, while MSW06E8-33S-SR is supplied in bag packaging. This distinction affects inventory management and handling procedures but does not impact connector performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS non-compliant, carry EAR99 ECCN classification, and are classified as active products. Compliance profiles are identical for regulatory and export control purposes.

Q: Can these connectors be used interchangeably in military applications?

A: Both connectors are designed for military applications with environment-resistant construction and bayonet lock fastening. Interchangeability depends on specific military specification requirements and whether gold contact finish is mandated by the applicable MIL standard or procurement document.
