3M 31160 Terminal Connector Rectangular Lug 400 MCM #1/2 Stud - Equivalent & Substitute Parts

Part Overview

The 3M 31160 is an active-status terminal connector designed as a rectangular lug for grounding applications. It accommodates 400 MCM (kcmil) wire gauge with a 1/2 inch stud connection. This component is used in high-amperage electrical termination systems where reliable grounding and power distribution are required. Substitute parts may be necessary due to inventory availability, supply chain constraints, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 31160 is determined by strict alignment of the following critical parameters:

• Wire gauge: 400 MCM (kcmil)
• Stud size: 1/2 inch
• Barrel inner diameter: 0.762" ± tolerance
• Barrel outer diameter: 0.950"
• Contact material: Copper
• Contact finish: Electro-Tin
• Termination method: Crimp, Barrel
• Mounting configuration: Free Hanging (In-Line)

The Panduit Corp LCC400-12-6 meets these substitution criteria. Both components are designed for identical wire gauge and stud configurations, feature matching barrel dimensions within acceptable tolerances, and employ the same crimp-barrel termination method. Both maintain copper construction with electro-tin finish and support non-insulated, free-hanging mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 31160 and Panduit LCC400-12-6 maintain active product status and full regulatory compliance. The 3M 31160 carries RoHS Compliant certification, while the Panduit LCC400-12-6 carries ROHS3 Compliant certification. Both components are REACH Unaffected and classified under identical ECCN and HTSUS codes, confirming equivalent regulatory standing.

Selection between these components should be based on inventory availability, lead time requirements, and established supplier relationships. Both components satisfy identical electrical and mechanical specifications for 400 MCM grounding terminal applications with 1/2 inch stud connections.

Frequently Asked Questions (FAQ)

Q: Can the Panduit LCC400-12-6 directly replace the 3M 31160 in existing installations?

A: Yes. Both components share identical wire gauge (400 MCM), stud size (1/2 inch), barrel dimensions (0.762" ID, 0.950" OD), contact material (copper), contact finish (electro-tin), and termination method (crimp, barrel). Dimensional variations (length 6.000" vs. 6.100", width 1.410" vs. 1.390") fall within acceptable tolerances for free-hanging in-line mounting applications.

Q: What is the difference between a rectangular lug and a rectangular tongue terminal?

A: Both terminal types accommodate identical wire gauges and stud sizes. The primary distinction lies in the terminal geometry and contact interface design. Both the 3M 31160 (lug) and Panduit LCC400-12-6 (tongue) are functionally equivalent for 400 MCM, 1/2 inch stud applications.

Q: Are there compliance differences between these components?

A: Both components are RoHS compliant and REACH Unaffected. The 3M 31160 carries RoHS Compliant certification, while the Panduit LCC400-12-6 carries ROHS3 Compliant certification. Both meet identical regulatory requirements for electrical terminal applications.

Q: What packaging is available for these components?

A: Both components are supplied in bulk packaging. The 3M 31160 has 854 pieces in stock, and the Panduit LCC400-12-6 has 1,168 pieces in stock.

Q: Are these components suitable for grounding applications?

A: Yes. The 3M 31160 is specifically designated as a grounding terminal. The Panduit LCC400-12-6 is designed for equivalent grounding and power distribution applications with identical electrical specifications.
