Engineering Selection Recommendations

Both the 3M 11-56S and Panduit P18-56R-C maintain active product status with full ROHS3 compliance and identical export classification (EAR99). The Panduit P18-56R-C incorporates a brazed seam construction with serrated termination features, while the 3M 11-56S utilizes butted seam construction. Both designs satisfy the specified electrical and mechanical requirements for 18-22 AWG circular ring terminals with 5/16 inch stud configuration. Selection between these parts may be based on inventory availability, supply chain considerations, or specific application requirements related to seam construction methodology.

Frequently Asked Questions (FAQ)

Q: Can the Panduit P18-56R-C directly replace the 3M 11-56S in existing applications?

A: Yes. Both parts maintain identical terminal type, stud size, wire gauge range, termination method, insulation classification, contact material, contact finish, and mounting configuration. Both are ROHS3 compliant and active products.

Q: What are the dimensional differences between these parts?

A: The width outer edges measurement differs slightly (3M: 0.470 inches vs. Panduit: 0.460 inches) and overall length differs marginally (3M: 0.880 inches vs. Panduit: 0.910 inches). These variations remain within acceptable tolerances for the 5/16 stud circular terminal category.

Q: Are there construction differences between the 3M and Panduit versions?

A: The 3M 11-56S features butted seam construction, while the Panduit P18-56R-C incorporates brazed seam construction with serrated termination. Both construction methods are suitable for crimp termination applications within the specified wire gauge range.

Q: Do both parts carry the same regulatory certifications?

A: Yes. Both the 3M 11-56S and Panduit P18-56R-C are ROHS3 compliant and classified under ECCN EAR99 with HTSUS code 8536.90.4000.

Q: What packaging options are available?

A: Both parts are supplied in bulk packaging format.
