LCB2-56WH-Q Equivalent & Substitute Parts

Part Overview

The LCB2-56WH-Q is a copper compression lug terminal manufactured by Panduit Corp, classified within the Pan-Lug™ series. This component is a rectangular tongue terminal designed for 2 AWG wire termination onto a 5/16" stud connection. The terminal features a crimp barrel termination method and electro-tin contact finish on copper base material. The LCB2-56WH-Q is designated as obsolete product status. Identification of equivalent and substitute parts is necessary to maintain circuit continuity and ensure procurement availability for applications requiring this terminal specification.

Substitute Part Grouping Explanation

Substitution eligibility for the LCB2-56WH-Q is determined by strict equivalence across electrical and mechanical parameters. The critical parameters governing substitution are: wire gauge (2 AWG), stud size (5/16"), terminal type (rectangular tongue), termination method (crimp barrel), contact material (copper), contact finish (electro-tin), barrel dimensions (ID 0.310", OD 0.420"), and ring ID (0.340").

The substitute part LCB2-56-Q maintains identical specifications across all critical electrical and mechanical parameters. Both parts share the same base product number (LCB2), series designation (Pan-Lug™), and manufacturing standard. The primary distinction between these parts is product status and packaging configuration. The LCB2-56WH-Q is obsolete, while the LCB2-56-Q maintains active product status with bulk packaging availability.

Engineering Selection Recommendations

The LCB2-56-Q is the direct substitute for the obsolete LCB2-56WH-Q. Both components are manufactured by Panduit Corp and maintain identical electrical and mechanical specifications across all critical parameters including wire gauge, stud size, terminal geometry, and contact properties.

The LCB2-56-Q offers the advantage of active product status, ensuring continued availability and supply chain reliability. This substitute part carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The bulk packaging configuration of the LCB2-56-Q provides flexibility for production environments requiring higher volume quantities.

Selection of the LCB2-56-Q eliminates obsolescence risk while maintaining complete functional and mechanical compatibility with applications originally specified for the LCB2-56WH-Q.

Frequently Asked Questions (FAQ)

Q: Are the LCB2-56WH-Q and LCB2-56-Q electrically equivalent?

A: Yes. Both terminals are rated for 2 AWG wire gauge and feature identical copper construction with electro-tin contact finish. The barrel dimensions (ID 0.310", OD 0.420") and ring ID (0.340") are identical, ensuring equivalent electrical performance and current-carrying capacity.

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

A: The LCB2-56WH-Q is designated as obsolete, while the LCB2-56-Q maintains active product status. The LCB2-56-Q is supplied in bulk packaging. Both parts share identical mechanical and electrical specifications.

Q: Can the LCB2-56-Q be used as a direct replacement in existing applications?

A: Yes. The LCB2-56-Q is a direct substitute for the LCB2-56WH-Q. All mounting dimensions, stud sizes, and termination specifications are identical. No design modifications are required.

Q: What compliance certifications does the substitute part carry?

A: The LCB2-56-Q is ROHS3 compliant and REACH unaffected. These certifications meet current regulatory standards for electronic component procurement.

Q: Are there any packaging considerations when switching to the LCB2-56-Q?

A: The LCB2-56-Q is supplied in bulk packaging, which differs from the original part's packaging configuration. Bulk packaging is suitable for production environments and offers cost efficiency for higher volume requirements.

Q: What is the wire gauge and stud size for this terminal?

A: The terminal is rated for 2 AWG wire and features a 5/16" stud connection point.

Q: Is the LCB2-56-Q insulated or non-insulated?

A: The LCB2-56-Q is non-insulated, matching the specification of the original LCB2-56WH-Q.
