3M 12-6-NB Ring Terminal Connector - Equivalent & Substitute Parts

Part Overview

The 3M 12-6-NB is an insulated ring terminal connector designed for 14-16 AWG wire applications with a #6 stud connection. This circular terminal features a crimp termination method and is constructed from polyamide nylon insulation with a butted seam design. The part is currently active in production with 713 units in stock. Ring terminal connectors of this specification are essential components in electrical assemblies where secure, reusable connections to threaded studs are required. Substitute parts may be necessary due to inventory availability, supply chain considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 12-6-NB is determined by strict alignment with the following critical parameters:

• Terminal Type: Must be Circular
• Stud/Tab Size: Must be #6 Stud
• Wire Gauge Range: Must accommodate 14-16 AWG
• Termination Method: Must be Crimp
• Insulation Material: Must be Polyamide (PA), Nylon
• Mounting Configuration: Must be Free Hanging (In-Line)
• Insulation Requirement: Must be Insulated
• Color: Blue
• Regulatory Compliance: Must maintain ROHS3 Compliant status

The Panduit Corp PN14-6R-C meets all mandatory substitution criteria within these parameter boundaries. Both parts share identical terminal type, stud size, wire gauge compatibility, termination method, insulation material, mounting type, and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 12-6-NB and Panduit PN14-6R-C are active production components with ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on:

• Inventory Availability: The Panduit PN14-6R-C currently has 3224 units in stock compared to 713 units for the 3M 12-6-NB, providing greater supply assurance.
• Regulatory Compliance: Both parts maintain identical ROHS3 Compliant status and HTSUS classification, ensuring equivalent regulatory standing.
• Series Designation: The Panduit part is designated within the Pan-Term® series, while the 3M part carries no series designation.
• Contact Material Specification: The Panduit PN14-6R-C specifies Copper contact material with Tin finish, whereas the 3M 12-6-NB does not provide contact material data.

Frequently Asked Questions (FAQ)

Q: Can the Panduit PN14-6R-C be used as a direct replacement for the 3M 12-6-NB?

A: Yes. Both parts meet identical specifications for terminal type, stud size, wire gauge range, termination method, insulation material, and mounting configuration. Both are ROHS3 compliant and carry the same HTSUS classification.

Q: What are the dimensional differences between these parts?

A: The 3M 12-6-NB has an outer width of 0.330" (8.38mm) and overall length of 0.910" (23.11mm). The Panduit PN14-6R-C measures 0.310" (7.87mm) in outer width and 0.850" (21.59mm) in overall length. Both maintain identical thickness of 0.030" (0.76mm).

Q: Are there insulation diameter differences?

A: Yes. The 3M 12-6-NB specifies an insulation diameter of 0.170" (4.32mm). The Panduit PN14-6R-C provides a range of 0.080" to 0.162" (2.03mm to 4.11mm), which encompasses the 3M specification within its upper tolerance band.

Q: Do both parts support the same wire gauge range?

A: Yes. Both the 3M 12-6-NB and Panduit PN14-6R-C are rated for 14-16 AWG wire applications.

Q: What is the packaging format for both parts?

A: Both parts are supplied in Bulk packaging format.

Q: Are there any moisture sensitivity considerations?

A: The 3M 12-6-NB carries an MSL rating of 1 (Unlimited). The Panduit PN14-6R-C is classified as Not Applicable for MSL.
