LCBX4/0-12F-X Equivalent & Substitute Parts

Part Overview

The LCBX4/0-12F-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4/0 AWG wire applications with a 1/2 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 LCBX4/0-12F-X is determined by strict equivalence across the following critical parameters:

Wire Gauge Compatibility: The substitute must accommodate 4/0 AWG wire, establishing the primary electrical interface requirement.

Stud Configuration: The 1/2 stud size must be maintained to ensure mechanical compatibility with mating hardware and mounting structures.

Terminal Geometry: Rectangular tongue terminal type with matching barrel and ring dimensions (Barrel ID: 0.650", Barrel OD: 0.810", Ring ID: 0.530") ensures proper wire seating and electrical contact.

Material and Finish Specifications: Copper contact material with electro-tin finish must be preserved to maintain electrical conductivity and corrosion resistance characteristics.

Termination Process: Crimp barrel termination method must remain consistent for assembly compatibility.

Regulatory Compliance: ROHS3 compliance status must be maintained for applications subject to environmental regulations.

The LCBX4/0-12-X meets all substitution criteria while offering active product status, making it a direct functional equivalent.

Engineering Selection Recommendations

The LCBX4/0-12-X is the direct substitute for the obsolete LCBX4/0-12F-X. Both parts share identical electrical and mechanical specifications across all critical parameters: wire gauge, stud size, terminal geometry, material composition, and contact finish.

The primary distinction is product status: LCBX4/0-12F-X is obsolete while LCBX4/0-12-X maintains active status with current manufacturing and inventory availability (686 pieces in stock). Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production.

The mounting type specification shows LCBX4/0-12-X as "Free Hanging (In-Line)" versus the main part's "Free Hanging (In-Line), Right Angle." The substitute accommodates the primary in-line mounting configuration. Applications requiring right-angle mounting should be evaluated against the substitute's in-line orientation.

Selection of LCBX4/0-12-X is appropriate for all applications currently specified for LCBX4/0-12F-X, with the exception of assemblies requiring right-angle mounting geometry.

Frequently Asked Questions (FAQ)

Q: Can LCBX4/0-12-X directly replace LCBX4/0-12F-X in existing assemblies?

A: Yes, for applications using in-line mounting. The substitute maintains identical electrical and mechanical specifications for wire gauge (4/0 AWG), stud size (1/2), terminal geometry, material, and finish. Applications requiring right-angle mounting should evaluate the substitute's in-line orientation against assembly requirements.

Q: What is the difference between the "F" designation in LCBX4/0-12F-X and the absence of "F" in LCBX4/0-12-X?

A: The provided data does not specify the technical meaning of the "F" designation. Both parts are functionally equivalent across all documented electrical and mechanical parameters.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both LCBX4/0-12F-X and LCBX4/0-12-X are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Q: Why is LCBX4/0-12F-X classified as obsolete?

A: Product status reflects manufacturing and distribution decisions by Panduit Corp. The active equivalent LCBX4/0-12-X provides continued access to this terminal specification.

Q: What packaging is available for the substitute part?

A: LCBX4/0-12-X is supplied in bulk packaging with 686 pieces currently in stock.

Q: Are the barrel dimensions identical between both parts?

A: Yes. Both parts feature identical barrel specifications: 0.650" (16.51mm) inner diameter and 0.810" (20.57mm) outer diameter, ensuring compatibility with 4/0 AWG wire and crimp tooling.

Q: Can these terminals be used in high-temperature applications?

A: The provided specifications do not include temperature rating data. Consult Panduit Corp technical documentation for thermal performance characteristics.
