M8-10R/SK Ring Terminal Connector - Equivalent & Substitute Parts

Part Overview

The M8-10R/SK is a ring terminal connector manufactured by 3M, designed for 8 AWG wire gauge applications with a #10 stud connection. This non-insulated circular terminal features a brazed seam construction and is classified as Active product status. The connector is RoHS Compliant and REACH Unaffected, making it suitable for applications requiring environmental compliance. Substitute parts are identified when inventory constraints, packaging requirements, or specific feature needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M8-10R/SK are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Wire Gauge: 8 AWG (exact match required)
• Terminal Type: Circular (exact match required)
• Stud/Tab Size: #10 Stud (exact match required)
• Termination Method: Crimp (exact match required)
• Mounting Type: Free Hanging (In-Line) (exact match required)
• Insulation: Non-Insulated (exact match required)

Secondary Considerations:

• Thickness, width, and length dimensions must fall within acceptable tolerance ranges for the application
• Product Status must be Active
• RoHS and REACH compliance status must meet or exceed the original specification

The identified substitute parts (2-33460-2 and P8-10R-T) satisfy all primary compatibility criteria and maintain Active product status with appropriate environmental compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and satisfy RoHS compliance requirements. The M8-10R/SK and P8-10R-T are supplied in Bulk packaging, while the 2-33460-2 is available in Cut Tape format. Selection between these parts should be based on:

Inventory Availability: The 2-33460-2 (TE Connectivity) offers the highest stock level at 15,056 pieces, followed by the M8-10R/SK at 988 pieces, and P8-10R-T at 1,564 pieces.

Dimensional Tolerance: The 2-33460-2 and P8-10R-T exhibit minor dimensional variations in thickness and overall length compared to the M8-10R/SK. These variations must be evaluated against specific application requirements to ensure mechanical fit within the target assembly.

Feature Differentiation: The 2-33460-2 includes serrated termination as an additional feature, which may provide enhanced mechanical retention in certain applications.

Compliance Certification: The P8-10R-T carries ROHS3 Compliant status, representing the most current RoHS revision level.

Frequently Asked Questions (FAQ)

Q: Can the 2-33460-2 substitute for the M8-10R/SK in all applications?

A: The 2-33460-2 matches all primary compatibility criteria (8 AWG wire gauge, #10 stud, circular terminal, crimp termination, non-insulated, free hanging mounting). Minor dimensional differences exist in thickness (0.048" vs. 0.050") and overall length (0.933" vs. 0.950"). Compatibility depends on whether these dimensional tolerances are acceptable within the specific application assembly.

Q: What is the difference between the packaging formats?

A: The M8-10R/SK and P8-10R-T are supplied in Bulk packaging, suitable for high-volume applications or custom kit assembly. The 2-33460-2 is supplied in Cut Tape (CT) format, which provides individual component separation and is typically used for automated assembly processes or smaller quantity requirements.

Q: Does the serrated termination feature on the 2-33460-2 affect compatibility?

A: The serrated termination is an additional feature that does not prevent substitution. It provides enhanced mechanical grip during the crimp process and may improve retention in vibration-prone applications. This feature is compatible with standard crimp tooling designed for 8 AWG #10 stud terminals.

Q: Are all three parts RoHS compliant?

A: Yes. The M8-10R/SK and 2-33460-2 are RoHS Compliant. The P8-10R-T is ROHS3 Compliant, which represents compliance with the most current RoHS revision and includes additional restricted substance requirements.

Q: What dimensional variations should I consider when selecting a substitute?

A: The thickness ranges from 0.040" (P8-10R-T) to 0.050" (M8-10R/SK), and overall length ranges from 0.933" (2-33460-2) to 1.140" (P8-10R-T). Width dimensions are consistent across all three parts at approximately 0.470". Verify that these dimensional ranges accommodate the stud hole spacing and assembly clearances in your target application.
