LCAS3/0-12-X Equivalent & Substitute Parts

Part Overview

The LCAS3/0-12-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 3/0 AWG wire termination with a 1/2 stud connection. This component is classified as obsolete, indicating that direct procurement from original manufacturing sources may be limited. The terminal features a crimp barrel termination method, electro-tin contact finish, and copper contact material suitable for high-amperage electrical applications. Identification of equivalent substitute parts is necessary to ensure continued availability and maintain system compatibility for applications currently utilizing this connector type.

Substitute Part Grouping Explanation

Substitution eligibility for the LCAS3/0-12-X is determined by strict equivalence across the following critical parameters: wire gauge (3/0 AWG), stud size (1/2), termination method (crimp barrel), barrel dimensions (ID 0.510", OD 0.640"), ring ID (0.530"), contact material (copper), contact finish (electro-tin), tab thickness (0.130"), and mounting configuration (free hanging in-line). The substitute part LCA3/0-12-X meets all these dimensional and material specifications. The primary distinction between the main part and the substitute is the terminal type: the LCAS3/0-12-X features a rectangular tongue configuration, while the LCA3/0-12-X is configured as a lug with grounding capability. Both parts share identical electrical and mechanical interface dimensions, allowing functional substitution in applications where the terminal style difference does not impose design constraints.

Engineering Selection Recommendations

The LCA3/0-12-X serves as the active substitute for the obsolete LCAS3/0-12-X. Both components are ROHS3 compliant and manufactured by Panduit Corp within the Pan-Lug™ series. The substitute part maintains full electrical and mechanical compatibility through identical barrel dimensions, ring ID specifications, contact material, and contact finish. The LCA3/0-12-X is currently in active production status with confirmed inventory availability (743 pieces), whereas the LCAS3/0-12-X is obsolete with limited stock (869 pieces). The primary design difference is the terminal configuration: the substitute features a lug with grounding capability and a 0.300" longer overall length (2.580" versus 2.280"). Selection of the LCA3/0-12-X is appropriate for applications where the lug terminal style and extended length do not conflict with mechanical or spatial constraints. Both parts support identical wire gauge (3/0 AWG) and stud size (1/2) specifications, ensuring equivalent electrical performance in high-amperage circuits.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the LCAS3/0-12-X and LCA3/0-12-X?

A: The LCAS3/0-12-X features a rectangular tongue terminal configuration, while the LCA3/0-12-X is configured as a lug with grounding capability. The LCA3/0-12-X is 0.300" longer overall (2.580" versus 2.280"). All electrical interface dimensions and material specifications are identical.

Q: Are the barrel dimensions identical between these two parts?

A: Yes. Both parts have a barrel ID of 0.510" (12.95mm), barrel OD of 0.640" (16.26mm), and ring ID of 0.530" (13.46mm). These dimensions ensure compatible wire termination and stud connection.

Q: Can the LCA3/0-12-X be used as a direct replacement for the LCAS3/0-12-X?

A: The LCA3/0-12-X is functionally compatible for applications where the lug terminal style and increased overall length do not impose design constraints. Mechanical fit within the assembly must be verified based on available space and terminal mounting configuration.

Q: What is the wire gauge capacity for both parts?

A: Both the LCAS3/0-12-X and LCA3/0-12-X are rated for 3/0 AWG wire termination with a 1/2 stud connection.

Q: Are both parts RoHS compliant?

A: Yes. Both the LCAS3/0-12-X and LCA3/0-12-X are ROHS3 compliant.

Q: Why is the LCAS3/0-12-X listed as obsolete?

A: The LCAS3/0-12-X is classified as obsolete, indicating that the manufacturer has discontinued active production. The LCA3/0-12-X remains in active production status and serves as the current equivalent offering.

Q: What is the contact material and finish for both parts?

A: Both parts feature copper contact material with an electro-tin contact finish, providing corrosion resistance and reliable electrical conductivity for high-amperage applications.
