L-12-6-NB Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The L-12-6-NB is a ring terminal connector manufactured by 3M, designed for circular stud applications with 14-16 AWG wire gauges. This insulated crimp terminal features a 6 stud configuration and is classified as an active product. Ring terminal connectors are essential components in electrical assemblies where secure, permanent wire termination to a fixed stud or bolt is required. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L-12-6-NB are identified based on strict equivalence of the following critical parameters:

• Terminal Type: Circular
• Stud/Tab Size: 6 Stud
• Wire Gauge: 14-16 AWG
• Termination Method: Crimp
• Insulation: Insulated
• Insulation Material: Polyamide (PA), Nylon
• Thickness: 0.030" (0.76mm)
• Width - Outer Edges: 0.310" (7.87mm)
• Mounting Type: Free Hanging (In-Line)

The substitute part PN14-6R-C from Panduit Corp meets all these critical parameters and is therefore electrically and mechanically compatible for direct substitution in applications requiring the L-12-6-NB.

Parameter Comparison

Engineering Selection Recommendations

Both the L-12-6-NB and PN14-6R-C are active products suitable for current applications. The PN14-6R-C offers ROHS3 compliance, which may be required for applications subject to RoHS regulations. The L-12-6-NB has a slightly longer overall length (0.940" versus 0.850"), which should be considered in space-constrained assemblies. Both parts share identical critical electrical and mechanical parameters, making them functionally equivalent for standard ring terminal connector applications with 14-16 AWG wire and 6 stud configurations.

Frequently Asked Questions (FAQ)

Q: Can PN14-6R-C be used as a direct replacement for L-12-6-NB?

A: Yes. Both parts meet the same critical specifications for terminal type, stud size, wire gauge, termination method, insulation material, and physical dimensions (thickness and width). The minor difference in overall length (0.090" shorter for PN14-6R-C) does not affect electrical compatibility but should be verified for mechanical fit in the specific assembly.

Q: What is the significance of the overall length difference?

A: The L-12-6-NB has an overall length of 0.940" while the PN14-6R-C measures 0.850". This 0.090" difference may impact clearance in confined spaces or affect the visual appearance of the assembly. Verify that the shorter length does not create mechanical interference in your application.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance is a regulatory requirement, not an electrical or mechanical parameter. The PN14-6R-C is ROHS3 compliant, while the L-12-6-NB status is not applicable. If your application requires RoHS compliance, the PN14-6R-C is the appropriate choice.

Q: Are the insulation diameters compatible?

A: The L-12-6-NB specifies an insulation diameter of 0.170" (4.32mm). The PN14-6R-C specifies a range of 0.080" to 0.162" (2.03mm to 4.11mm). The PN14-6R-C range does not fully encompass the L-12-6-NB specification. Verify wire fit during assembly.

Q: What packaging options are available?

A: Both parts are supplied in bulk packaging. Inventory availability should be confirmed with the respective manufacturers or authorized distributors.
