MS3112E8-3S Equivalent & Substitute Parts

Part Overview

The MS3112E8-3S is a 3-position circular connector receptacle manufactured by ITT Cannon, LLC, designed for panel mount applications with bayonet lock fastening. This connector features female sockets with solder cup termination, rated for 7.5A at 600VAC/850VDC, and operates across -55°C to 125°C. The part is Active in product status with 1,073 units in stock. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and termination methods align with the original specification, enabling direct replacement in applications where the connector footprint and performance requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MS3112E8-3S is determined by strict alignment of the following parameters:

• Connector Type & Position Count: Receptacle configuration with 3 positions
• Shell Size - Insert: 8-3 dimension specification
• Mounting Configuration: Panel mount with flange-mounted bayonet lock fastening
• Termination Method: Solder cup termination
• Electrical Performance: Current rating of 7.5A and voltage rating compatibility
• Operating Temperature Range: -55°C to 125°C
• Environmental Resistance: Environment resistant ingress protection

The MSW02E8-3S meets all substitution criteria. Both connectors share identical position count, shell size, mounting type, fastening mechanism, termination method, current rating, operating temperature range, and environmental resistance classification. Voltage rating for the substitute (800V) exceeds the original specification (600VAC/850VDC), ensuring compatibility in applications requiring the original voltage parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the MS3112E8-3S and MSW02E8-3S are Active products with current inventory availability. Selection between these parts should be based on:

Compliance & Regulatory Status: The MS3112E8-3S carries REACH Affected status, while the MSW02E8-3S shows Vendor Undefined REACH status. Both are RoHS non-compliant and classified under ECCN EAR99. Organizations with specific REACH compliance requirements should verify the MSW02E8-3S status with the manufacturer before selection.

Contact Finish Specification: The MS3112E8-3S specifies gold mating contact finish at 50.0µin (1.27µm) thickness. The MSW02E8-3S specifies cadmium contact finish. Applications requiring gold-plated contacts for enhanced corrosion resistance or specific electrical properties should retain the original MS3112E8-3S.

Shell Finish: The MS3112E8-3S features Olive Drab Cadmium finish, while the MSW02E8-3S specifies Cadmium finish. Environmental or aesthetic requirements may influence selection.

Packaging: MS3112E8-3S is supplied in Bulk packaging; MSW02E8-3S is supplied in Bag packaging. Procurement and handling procedures may differ accordingly.

Frequently Asked Questions (FAQ)

Q: Can the MSW02E8-3S directly replace the MS3112E8-3S in all applications?

A: Direct replacement is possible when the application does not require gold-plated mating contacts. Both connectors share identical electrical ratings (7.5A), voltage compatibility (800V exceeds 600VAC/850VDC), operating temperature range (-55°C to 125°C), and mechanical configuration (3-position, 8-3 shell size, bayonet lock, solder cup termination). Contact finish differences must be evaluated against application requirements.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: connector type (receptacle, female sockets), position count (3), shell size (8-3), mounting type (panel mount with flange), fastening mechanism (bayonet lock), termination method (solder cup), current rating (7.5A), operating temperature range (-55°C to 125°C), and environmental resistance classification. Voltage rating of the substitute must equal or exceed the original specification.

Q: Does the difference in shell finish affect electrical performance?

A: Shell finish (Olive Drab Cadmium vs. Cadmium) does not affect electrical performance. Selection should be based on environmental exposure requirements, corrosion resistance specifications, or aesthetic standards defined by the application or system design.

Q: Are there inventory considerations when selecting between these parts?

A: The MS3112E8-3S has 1,073 units in stock (Bulk packaging), while the MSW02E8-3S has 844 units in stock (Bag packaging). Procurement lead times and packaging requirements may influence availability for specific production schedules.

Q: What compliance differences exist between these connectors?

A: Both parts are RoHS non-compliant and classified as EAR99. The MS3112E8-3S is REACH Affected; the MSW02E8-3S shows Vendor Undefined REACH status. Organizations with mandatory REACH compliance requirements should confirm the MSW02E8-3S status with Milspecwest, LLC before procurement.
