LCCF4/0-12F-X Equivalent & Substitute Parts

Part Overview

The LCCF4/0-12F-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 eligibility for the LCCF4/0-12F-X is determined by strict equivalence across the following critical parameters:

Wire gauge (4/0 AWG) establishes the current-carrying capacity and barrel diameter specifications. Stud size (1/2) defines the mounting interface and mechanical compatibility. Terminal type (rectangular tongue) and termination method (crimp barrel) establish the functional connection architecture. Barrel dimensions (ID 0.630", OD 0.910") and ring ID (0.530") ensure proper wire seating and contact integrity. Contact material (copper) and finish (electro-tin) determine electrical conductivity and corrosion resistance. Compliance certifications (ROHS3, REACH Unaffected) establish regulatory equivalence.

The substitute part LCCF4/0-12-X maintains identical specifications across all critical parameters, with the primary distinction being product status (active versus obsolete) and packaging configuration (bulk versus original packaging).

Engineering Selection Recommendations

The LCCF4/0-12-X is the direct functional equivalent to the obsolete LCCF4/0-12F-X. Both parts share identical electrical and mechanical specifications, including wire gauge, stud size, barrel dimensions, contact material, and contact finish. Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence.

The primary distinction between these parts is product status: LCCF4/0-12F-X is obsolete, while LCCF4/0-12-X is active and currently in production. The LCCF4/0-12-X is supplied in bulk packaging, whereas the main part was supplied in original packaging. Current inventory availability shows 778 units of the substitute part in stock.

For applications currently specified with LCCF4/0-12F-X, direct substitution with LCCF4/0-12-X is supported by complete parameter equivalence and active product status.

Frequently Asked Questions (FAQ)

Q: Can LCCF4/0-12-X be used as a direct replacement for LCCF4/0-12F-X?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: wire gauge (4/0 AWG), stud size (1/2), barrel dimensions, contact material (copper), and contact finish (electro-tin). The substitute part is active and currently in production.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete versus active) and packaging configuration (original packaging versus bulk). All functional specifications are identical.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain identical compliance certifications: ROHS3 compliant, REACH unaffected, and EAR99 export classification.

Q: Does the mounting type differ between these parts?

A: The main part LCCF4/0-12F-X specifies mounting type as "Free Hanging (In-Line), Right Angle." The substitute part LCCF4/0-12-X specifies mounting type as "Free Hanging (In-Line)." Both support free hanging in-line mounting configurations.

Q: What is the overall length difference?

A: The main part does not specify overall length. The substitute part specifies overall length as 5.230" (132.84mm).

Q: Is inventory availability a consideration for selection?

A: The substitute part LCCF4/0-12-X has 778 units in current stock. The main part LCCF4/0-12F-X, being obsolete, has 955 units listed as new original in stock but is no longer in active production.
