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

Part Overview

The LCC4/0-12D-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4/0 AWG wire gauge applications with a 1/2 inch stud connection. This non-insulated copper terminal features electro-tin contact finish and is rated for crimp barrel termination. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this terminal specification.

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

Wire Gauge: 4/0 AWG
Stud/Tab Size: 1/2 Stud
Terminal Type: Rectangular Tongue
Termination Method: Crimp, Barrel
Contact Material: Copper
Contact Finish: Electro-Tin
Insulation: Non-Insulated
Barrel ID: 0.570" (14.48mm)
Barrel OD: 0.710" (18.03mm)
Ring ID: 0.530" (13.46mm)
Tab Thickness: 0.140" (3.56mm)
Terminal Style: Two Stud Holes
Mounting Type: Free Hanging (In-Line)

Engineering Selection Recommendations

The LCC4/0-12-X serves as the active equivalent for the obsolete LCC4/0-12D-X. Both parts maintain identical electrical and mechanical specifications across all critical parameters including wire gauge, stud size, barrel dimensions, and contact properties. The substitute part is currently in active production status with confirmed inventory availability.

Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current applications. The LCC4/0-12-X is available in bulk packaging with 1000 pieces in stock, compared to the obsolete part's limited remaining inventory of 851 pieces.

The primary dimensional difference is overall length: the substitute measures 5.130 inches (130.30mm) versus the main part's 4.220 inches (107.19mm). This length variation does not affect terminal function, electrical performance, or mechanical compatibility with standard 4/0 AWG wire and 1/2 inch stud applications.

Frequently Asked Questions (FAQ)

Q: Can LCC4/0-12-X directly replace LCC4/0-12D-X in existing applications?

A: Yes. Both parts share identical wire gauge (4/0 AWG), stud size (1/2 inch), barrel dimensions, contact material, and termination method. The substitute is electrically and mechanically equivalent for standard applications.

Q: What is the significance of the length difference between these parts?

A: The LCC4/0-12-X is 0.910 inches (23.11mm) longer overall. This dimension difference does not affect electrical performance or compatibility with wire and stud specifications. Physical space constraints in the application must be evaluated independently.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both LCC4/0-12D-X and LCC4/0-12-X are ROHS3 compliant and REACH unaffected, meeting current environmental and safety requirements.

Q: Why is the main part listed as obsolete?

A: The LCC4/0-12D-X is no longer in active production. The LCC4/0-12-X represents the current active equivalent from Panduit Corp's Pan-Lug™ series.

Q: What packaging options are available for the substitute part?

A: The LCC4/0-12-X is supplied in bulk packaging with 1000 pieces per order, compared to the original part's standard packaging configuration.

Q: Are the contact finish and material identical between both parts?

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

Q: Can these parts be used interchangeably in high-current applications?

A: Yes. Both parts are rated for 4/0 AWG wire gauge with identical barrel and ring dimensions, supporting equivalent current-carrying capacity.
