3M 11-4S-NB Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The 3M 11-4S-NB is an insulated ring terminal connector designed for circular stud applications with 18-22 AWG wire gauges. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified when organizations require alternative sourcing due to inventory constraints, supply chain considerations, or procurement preferences while maintaining identical functional and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 11-4S-NB is determined by strict alignment of the following critical parameters:

• Terminal Type: Circular configuration
• Stud/Tab Size: 4 Stud specification
• Wire Gauge Range: 18-22 AWG
• Termination Method: Crimp connection
• Insulation Diameter: 0.145" (3.68mm)
• Insulation Material: Polyamide (PA), Nylon
• Mounting Type: Free Hanging (In-Line)
• Color: Red
• RoHS Compliance: ROHS3 Compliant

The Panduit Corp PN18-4R-C meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 11-4S-NB and Panduit PN18-4R-C maintain Active product status and ROHS3 compliance. Selection between these components should be based on:

• Inventory availability and lead time requirements
• Procurement source preferences
• Minor dimensional tolerances: The Panduit PN18-4R-C exhibits a thickness of 0.032" (0.81mm) compared to 0.030" (0.76mm) for the 3M part, and an overall length of 0.800" (20.32mm) versus 0.790" (20.07mm)
• Contact material specifications: Panduit PN18-4R-C specifies Copper with Tin finish; 3M 11-4S-NB does not provide contact material data

Frequently Asked Questions (FAQ)

Q: Can the Panduit PN18-4R-C be used as a direct replacement for the 3M 11-4S-NB?

A: Yes. Both components share identical terminal type, stud size, wire gauge range, insulation specifications, and mounting configuration. Minor dimensional variations in thickness and length fall within acceptable mechanical tolerances for this connector category.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: circular terminal type, 4 stud configuration, 18-22 AWG wire gauge range, crimp termination method, 0.145" insulation diameter, polyamide nylon insulation material, free hanging in-line mounting, and red color specification.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and classified under the same ECCN (EAR99) and HTSUS code (8536.90.4000). The Panduit part includes REACH Unaffected status; the 3M part does not specify REACH status.

Q: What packaging options are available?

A: Both components are supplied in Bulk packaging format.

Q: How do the dimensional specifications compare?

A: The Panduit PN18-4R-C is marginally thicker (0.032" versus 0.030") and slightly longer (0.800" versus 0.790"). Width remains identical at 0.250". These minor variations do not affect functional compatibility in standard applications.
