3M 40170 Scotchlok™ Aluminum Two Hole Lug - Equivalent & Substitute Parts

Part Overview

The 3M 40170 is an aluminum terminal connector rectangular lug designed for grounding applications with 600MCM (kcmil) wire gauge capacity and 1/2 stud mounting. This component is classified as a non-insulated, crimp barrel termination device with two stud holes for free-hanging in-line installation. The part maintains Active product status and is RoHS Compliant, making it suitable for current procurement and deployment in electrical distribution systems requiring high-capacity grounding connections.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, ensuring functional interchangeability within the defined application scope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 40170 is determined by strict alignment of the following critical parameters:

• Wire gauge capacity: 600MCM (kcmil)
• Stud/tab size: 1/2 Stud
• Terminal style: Two stud holes
• Termination method: Crimp, barrel
• Contact material: Aluminum
• Barrel dimensions (ID/OD tolerance): Within specified ranges
• Mounting configuration: Free hanging (in-line)
• Regulatory compliance: RoHS and REACH status

The Panduit Corp LAB600-12-2 qualifies as a substitute based on matching all critical electrical and mechanical parameters. Dimensional variations within manufacturing tolerance and terminal type differentiation (rectangular tongue versus rectangular lug) do not preclude functional equivalence in grounding applications with identical wire gauge and stud specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 40170 and Panduit LAB600-12-2 maintain Active product status with current regulatory compliance certifications. The 3M 40170 is RoHS Compliant, while the Panduit substitute carries ROHS3 Compliant designation, indicating alignment with current environmental standards. Both components are REACH Unaffected and classified under identical HTSUS and ECCN codes (8536.90.4000 and EAR99 respectively).

Selection between these parts should be based on availability, packaging requirements (3M supplied in Box; Panduit in Bulk), and application-specific performance characteristics such as the Panduit part's gel-filled feature. Barrel dimension tolerances are within acceptable ranges for 600MCM wire termination, and both aluminum contact materials provide equivalent electrical conductivity for grounding applications.

Frequently Asked Questions (FAQ)

Q: Can the Panduit LAB600-12-2 directly replace the 3M 40170 in existing installations?

A: Yes, provided the application requirements align with the specified wire gauge (600MCM), stud size (1/2), and mounting configuration (free-hanging in-line). Both parts are aluminum contact, non-insulated, crimp barrel terminals with two stud holes.

Q: What is the significance of the terminal type difference (rectangular lug versus rectangular tongue)?

A: Both terminal styles accommodate the same stud size and wire gauge. The functional difference relates to the connection interface geometry; however, both are designed for identical 1/2 stud applications and do not affect electrical performance in grounding circuits.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The 3M 40170 is supplied in Box packaging (745 pcs available), while the Panduit LAB600-12-2 is supplied in Bulk packaging (695 pcs available). Procurement and inventory management processes should account for these packaging differences.

Q: Do both parts meet current regulatory requirements?

A: Both parts are Active status with current compliance certifications. The 3M 40170 is RoHS Compliant; the Panduit LAB600-12-2 is ROHS3 Compliant. Both are REACH Unaffected. Selection should align with your specific regulatory framework requirements.

Q: What is the gel-filled feature on the Panduit part?

A: The gel-filled feature on the Panduit LAB600-12-2 provides additional environmental protection. This specification is provided for reference; compatibility with your application should be confirmed based on operational environment and performance requirements.

Q: Are the dimensional differences between these parts significant?

A: Dimensional variations (overall length 7.750" vs. 7.550"; width 1.750" vs. 1.720") are within manufacturing tolerance ranges for this component category. Barrel ID/OD dimensions are equivalent within tolerance, ensuring proper wire termination and stud fit.
