Substitute Part Grouping Explanation

Substitution of the obsolete LCB4/0-12W-X is based on electrical and mechanical parameter equivalence. The primary substitute, LCB4/0-12-X, maintains identical specifications across all critical functional parameters: wire gauge (4/0 AWG), stud size (1/2 Stud), terminal type (Rectangular Tongue), termination method (Crimp, Barrel), and all dimensional specifications including barrel diameter, ring diameter, and tab thickness.

The substitution is valid based on the following matching parameters:

Wire Gauge: 4/0 AWG (identical)
Stud/Tab Size: 1/2 Stud (identical)
Terminal Type: Rectangular Tongue (identical)
Termination: Crimp, Barrel (identical)
Tab Thickness: 0.140" (3.56mm) (identical)
Barrel ID: 0.570" (14.48mm) (identical)

Engineering Selection Recommendations

The LCB4/0-12-X serves as the direct equivalent for the obsolete LCB4/0-12W-X. Selection of the substitute part is based on the following engineering criteria:

Product Status: The LCB4/0-12-X is classified as Active, ensuring ongoing availability and supply chain reliability, whereas the main part is Obsolete.

Regulatory Compliance: The LCB4/0-12-X carries ROHS3 Compliant and REACH Unaffected certifications, meeting current environmental and regulatory requirements for component procurement.

Functional Equivalence: All critical electrical and mechanical parameters are identical between the main part and substitute, including wire gauge, stud size, terminal geometry, barrel dimensions, and contact specifications.

Dimensional Consideration: The overall length differs by 0.180" (4.57mm), with the substitute measuring 3.220" (81.79mm) compared to the main part's 3.040" (77.22mm). This dimensional variance must be evaluated within the context of the specific application's spatial constraints.

Frequently Asked Questions (FAQ)

Q: Can LCB4/0-12-X be used as a direct replacement for LCB4/0-12W-X?

A: Yes. The LCB4/0-12-X is electrically and mechanically equivalent to the LCB4/0-12W-X across all functional parameters including wire gauge, stud size, terminal type, termination method, and dimensional specifications for the barrel and ring. The substitute is an active product with current regulatory compliance.

Q: What is the difference in overall length between these parts?

A: The LCB4/0-12-X has an overall length of 3.220" (81.79mm), compared to 3.040" (77.22mm) for the LCB4/0-12W-X. This 0.180" (4.57mm) difference must be considered in applications with space constraints.
