Substitute Part Grouping Explanation

Substitution of the obsolete LCC4/0-12WF-X is based on electrical and mechanical parameter equivalence within the Pan-Lug™ series. The substitute part LCC4/0-12W-X maintains identical specifications across all critical parameters that determine functional compatibility:

Critical Equivalence Parameters:

Wire gauge (4/0 AWG)
Stud size (1/2 stud)
Terminal type (Rectangular Tongue)
Termination method (Crimp, Barrel)
Barrel dimensions (ID: 0.570", OD: 0.710")
Ring ID (0.530")
Tab thickness (0.140")
Contact material and finish (Copper, Electro-Tin)
Insulation type (Non-Insulated)
Regulatory compliance (ROHS3, REACH Unaffected)

The substitute part differs only in mounting type classification and product status, with the substitute being an active product available in bulk packaging.

Engineering Selection Recommendations

The LCC4/0-12W-X is the direct functional equivalent for applications currently specified with the LCC4/0-12WF-X. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part is classified as obsolete, while the substitute maintains active product status with confirmed inventory availability (824 pieces in stock). This ensures long-term supply chain reliability and continued manufacturer support.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, confirming suitability for regulated applications without additional qualification requirements.

Electrical and Mechanical Equivalence: All critical parameters determining terminal function, wire termination capacity, and stud connection compatibility are identical between the main part and substitute. The parts are mechanically and electrically interchangeable within the specified application envelope.

Packaging Consideration: The substitute is supplied in bulk packaging, which may require adjustment to procurement and inventory management procedures compared to the original packaging specification.

Frequently Asked Questions (FAQ)

Q: Are LCC4/0-12WF-X and LCC4/0-12W-X electrically equivalent?

A: Yes. Both parts are rated for 4/0 AWG wire termination with identical barrel dimensions (0.570" ID, 0.710" OD), contact material (Copper), and contact finish (Electro-Tin). Electrical performance is equivalent.

Q: Can LCC4/0-12W-X be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical mechanical dimensions, stud size (1/2), tab thickness (0.140"), and terminal configuration. Direct substitution is supported without design modification.

Q: What is the difference between the main part and substitute?

A: The primary differences are product status (obsolete versus active) and packaging format. The main part is obsolete; the substitute is an active product supplied in bulk packaging. All functional and compliance parameters are identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both LCC4/0-12WF-X and LCC4/0-12W-X are ROHS3 compliant and REACH unaffected, confirming regulatory equivalence for applications subject to these standards.

Q: What wire gauge does this terminal accommodate?

A: Both parts are rated for 4/0 AWG wire termination using crimp and barrel termination methods.

Q: Is the stud size identical between both parts?

A: Yes. Both parts feature a 1/2 stud connection with two stud holes, maintaining identical mounting compatibility.

Q: What is the contact material and finish?

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