11-8S-NB Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The 3M 11-8S-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. Ring terminal connectors serve as termination points in electrical assemblies where secure, repeatable connections to fixed studs are required. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 11-8S-NB is determined by the following critical parameters:

• Terminal Type: Must be Circular
• Stud/Tab Size: Must be 8 Stud
• Wire Gauge Range: Must accommodate 18-22 AWG
• Termination Method: Must be Crimp
• Insulation Material: Must be Polyamide (PA), Nylon
• Mounting Type: Must be Free Hanging (In-Line)
• Regulatory Compliance: Must maintain ROHS3 compliance

The substitute part PN18-8R-C from Panduit Corp meets all critical substitution criteria. Both parts share identical functional specifications for terminal type, stud size, wire gauge compatibility, termination method, insulation material, and mounting configuration. Dimensional variations within acceptable tolerances do not preclude substitution when electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 11-8S-NB and Panduit PN18-8R-C maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The Panduit PN18-8R-C provides an equivalent functional alternative with documented contact material (Copper) and contact finish (Tin) specifications, whereas the 3M part does not specify these parameters in the provided data.

Dimensional differences between the two parts are minor and fall within typical manufacturing tolerances for this component category. The Panduit part offers a wider insulation diameter range (0.080" ~ 0.145") compared to the fixed 0.145" specification of the 3M part, providing greater accommodation for wire insulation variations within the 18-22 AWG range.

Selection between these parts should be based on availability, lead time requirements, and specific assembly space constraints where dimensional variations may be relevant.

Frequently Asked Questions (FAQ)

Q: Can the Panduit PN18-8R-C be used as a direct replacement for the 3M 11-8S-NB?

A: Yes. Both parts are functionally equivalent for applications requiring an 8 stud circular ring terminal connector with 18-22 AWG crimp termination and nylon insulation. The parts share identical terminal type, stud size, wire gauge compatibility, and mounting configuration.

Q: What are the key differences between these two parts?

A: The primary differences are dimensional. The Panduit part is slightly larger in thickness (0.032" vs 0.030"), width (0.310" vs 0.250"), and length (0.860" vs 0.790"). The Panduit part also specifies a wider insulation diameter range. These variations do not affect electrical or mechanical interface compatibility for standard applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3M 11-8S-NB and Panduit PN18-8R-C are ROHS3 compliant and suitable for applications with RoHS requirements.

Q: What wire gauges are supported by these connectors?

A: Both parts support 18-22 AWG wire gauges with crimp termination. The Panduit part accommodates insulation diameters from 0.080" to 0.145", while the 3M part is specified at 0.145".

Q: Are these parts available in bulk packaging?

A: Yes. Both parts are supplied in bulk packaging. Current inventory includes 1590 pieces for the 3M 11-8S-NB and 1247 pieces for the Panduit PN18-8R-C.
