LCC4/0-12WH-X Equivalent & Substitute Parts

Part Overview

The LCC4/0-12WH-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4/0 AWG wire termination with a 1/2 stud connection. This component is classified as obsolete, indicating discontinuation from active production. The part features non-insulated copper construction with electro-tin contact finish, suitable for high-amperage electrical applications requiring reliable crimp-barrel termination.

Due to its obsolete status, identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for repair, maintenance, and new installations where this terminal specification is required.

Substitute Part Grouping Explanation

Substitution of the LCC4/0-12WH-X is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

Wire gauge (4/0 AWG)
Barrel inner diameter (0.570")
Barrel outer diameter (0.710")
Ring inner diameter (0.530")
Contact material (Copper)
Contact finish (Electro-Tin)

Mechanical Compatibility Parameters:

Terminal type (Rectangular Tongue)
Stud/tab size (1/2 Stud)
Tab thickness (0.140")
Termination method (Crimp, Barrel)
Terminal style (Two Stud Holes)

Regulatory Compliance Parameters:

RoHS3 Compliance
REACH Unaffected status

The substitute part LCC4/0-12W-X maintains identical electrical and mechanical specifications while differing in mounting configuration and product status. The primary distinction is the removal of the 45° angle mounting feature present in the main part, resulting in a free-hanging in-line orientation.

Engineering Selection Recommendations

The LCC4/0-12W-X serves as a direct functional substitute for the obsolete LCC4/0-12WH-X. Both components maintain identical electrical and mechanical specifications across all critical parameters including wire gauge, barrel dimensions, contact material, and termination method.

Product Status Consideration: The LCC4/0-12W-X holds active product status, ensuring continued availability and manufacturing support. The LCC4/0-12WH-X is obsolete and subject to discontinuation of supply.

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Mounting Configuration Difference: The primary distinction between these parts is the mounting orientation. The LCC4/0-12WH-X includes a 45° angle mounting feature, while the LCC4/0-12W-X provides free-hanging in-line orientation. Component selection should account for the specific mounting requirements of the application.

Inventory Availability: The LCC4/0-12W-X demonstrates current stock availability (824 units), supporting immediate procurement for new installations and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the LCC4/0-12W-X replace the LCC4/0-12WH-X in all applications?

A: The LCC4/0-12W-X provides electrical and mechanical equivalence for all crimp-barrel termination functions. The primary consideration is mounting orientation. The LCC4/0-12WH-X includes 45° angle mounting, while the LCC4/0-12W-X provides in-line orientation. Application compatibility depends on whether the mounting angle is a design requirement.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by equivalence in wire gauge (4/0 AWG), stud size (1/2), barrel dimensions (0.570" ID, 0.710" OD), ring diameter (0.530" ID), contact material (Copper), contact finish (Electro-Tin), tab thickness (0.140"), and termination method (Crimp, Barrel).

Q: Are there compliance differences between these parts?

A: Both parts maintain identical compliance status: ROHS3 compliant and REACH unaffected. No regulatory differentiation exists between the two components.

Q: What is the significance of the obsolete status of the LCC4/0-12WH-X?

A: Obsolete status indicates the part is no longer in active production. The LCC4/0-12W-X, with active status, ensures continued manufacturing availability and supply chain reliability for future procurement needs.

Q: How do the packaging specifications differ?

A: The LCC4/0-12WH-X packaging is not specified in available documentation. The LCC4/0-12W-X is supplied in bulk packaging. Packaging format should be confirmed with the supplier based on specific procurement requirements.

Q: Are the electrical performance characteristics identical?

A: Yes. Both components feature identical copper construction with electro-tin contact finish, barrel dimensions, and ring specifications. Electrical performance in crimp-barrel termination applications is equivalent.
