Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 13-56S-W is determined by strict equivalence across the following critical parameters:

• Terminal Type: Circular ring configuration
• Wire Gauge: 10-12 AWG
• Stud/Tab Size: 5/16" stud diameter
• Termination Method: Crimp connection
• Contact Material: Copper with tin finish
• Insulation: Non-insulated construction
• Mounting Configuration: Free hanging in-line orientation

The Panduit Corp P10-56R-L meets all substitution criteria. Minor dimensional variations in width and length fall within acceptable tolerances for this terminal category and do not affect functional compatibility or stud engagement.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 13-56S-W and Panduit P10-56R-L are active production parts with ROHS3 compliance certification. Selection between these parts should be based on availability, lead time, and cost considerations. The Panduit P10-56R-L includes serrated termination features in addition to the brazed seam construction, which may provide enhanced mechanical retention in certain applications. Both parts maintain identical electrical and mechanical specifications for wire gauge, stud size, and contact material composition. Inventory availability shows 2181 units for the Panduit substitute versus 939 units for the 3M original part.

Frequently Asked Questions (FAQ)

Q: Can the Panduit P10-56R-L be used as a direct replacement for the 3M 13-56S-W?

A: Yes. Both parts are functionally equivalent for 10-12 AWG wire termination on 5/16" studs. Dimensional tolerances are within acceptable ranges for this terminal category.

Q: What is the significance of the serrated termination feature on the Panduit part?

A: The serrated termination on the Panduit P10-56R-L provides additional mechanical grip during the crimp process. This is a supplementary feature that does not affect compatibility with standard crimp tooling.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications. The Panduit part includes REACH Unaffected status documentation.

Q: Do dimensional differences affect installation?

A: No. The width and length variations (0.020" and 0.010" respectively) are within standard manufacturing tolerances for ring terminals and do not impact stud engagement or electrical performance.

Q: What packaging options are available?

A: Both parts are supplied in bulk packaging suitable for production assembly environments.
