Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCA400-78-6 is determined by strict alignment of the following critical parameters:

Core Substitution Criteria:

• Wire gauge: 400MCM (kcmil)
• Terminal type: Rectangular Tongue
• Tab thickness: 0.180" (4.57mm)
• Overall length: 3.810" (96.77mm)
• Outer width: 1.390" (35.31mm)
• Termination method: Crimp, Barrel
• Barrel ID: 0.760" (19.30mm)
• Barrel OD: 0.950" (24.13mm)
• Contact material: Copper
• Contact finish: Electro-Tin
• Insulation: Non-Insulated
• Regulatory compliance: ROHS3 Compliant

The LCA400-00-6 qualifies as a substitute based on matching all core electrical and mechanical parameters. The primary distinction is the terminal style configuration: the LCA400-78-6 includes a 7/8 stud hole, while the LCA400-00-6 features no stud hole design. Both components share identical wire gauge capacity, barrel dimensions, contact properties, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LCA400-00-6 is the active equivalent for the obsolete LCA400-78-6. Both components maintain identical electrical performance characteristics for 400MCM wire termination applications, with matching barrel dimensions, contact materials, and finish specifications.

Product Status Consideration: The LCA400-78-6 is classified as obsolete, while the LCA400-00-6 maintains active status with confirmed inventory availability (1117 pieces in stock versus 866 pieces for the obsolete variant).

Regulatory Compliance: Both parts satisfy ROHS3 compliance requirements and maintain REACH unaffected status, ensuring compatibility with current environmental and safety standards.

Functional Distinction: The primary design difference is the terminal style configuration. The LCA400-78-6 incorporates a single stud hole design with 7/8 stud specification, whereas the LCA400-00-6 features a no stud hole configuration. This distinction affects mounting methodology and application-specific installation requirements.

Selection between these components depends on the specific mounting and connection requirements of the target application. Both maintain equivalent electrical performance for 400MCM wire gauge termination.

Frequently Asked Questions (FAQ)

Q: Can the LCA400-00-6 directly replace the LCA400-78-6 in all applications?

A: The LCA400-00-6 matches all critical electrical and mechanical parameters including wire gauge, barrel dimensions, contact material, and finish. The primary difference is the terminal style: the LCA400-78-6 includes a 7/8 stud hole, while the LCA400-00-6 has no stud hole. Substitution is valid only when the application does not require the stud hole mounting feature.

Q: What is the significance of the "7/8 Stud" designation in the LCA400-78-6?

A: The 7/8 stud specification indicates the terminal includes a single stud hole with 7/8 inch diameter, designed for direct mounting to a 7/8 inch stud or bolt. This feature is absent in the LCA400-00-6, which uses a free-hanging in-line mounting approach.

Q: Are both parts suitable for 400MCM wire applications?

A: Yes. Both the LCA400-78-6 and LCA400-00-6 are rated for 400MCM (kcmil) wire gauge. The barrel ID of 0.760 inches and barrel OD of 0.950 inches are identical across both components, ensuring equivalent wire termination capacity.

Q: What is the difference in packaging between these parts?

A: The LCA400-78-6 is listed with unspecified packaging, while the LCA400-00-6 is supplied in bulk packaging. Packaging differences do not affect component functionality or electrical performance.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both the LCA400-78-6 and LCA400-00-6 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the LCA400-78-6 classified as obsolete?

A: The LCA400-78-6 is obsolete status, indicating it is no longer in active production. The LCA400-00-6 represents the active alternative within the Pan-Lug™ series for 400MCM rectangular tongue terminal applications.

Q: Are the contact materials and finishes identical?

A: Yes. Both components feature copper contact material with electro-tin finish, ensuring equivalent electrical conductivity and corrosion resistance properties.
