LCAS1/0-56-X Equivalent & Substitute Parts

Part Overview

The LCAS1/0-56-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 1/0 AWG wire gauge applications with a 5/16 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 of the obsolete LCAS1/0-56-X is determined by strict equivalence across critical electrical and mechanical parameters. The substitute part LCA1/0-56-X maintains identical specifications for wire gauge (1/0 AWG), stud size (5/16), terminal type (rectangular tongue), termination method (crimp barrel), contact material (copper), contact finish (electro-tin), insulation status (non-insulated), and all barrel and ring dimensional specifications.

The primary distinction between the main part and substitute is overall length: LCAS1/0-56-X measures 1.720" (43.69mm) while LCA1/0-56-X measures 2.000" (50.80mm). This dimensional variance does not affect electrical performance or mechanical compatibility with the 5/16 stud connection. The substitute part carries active product status and maintains full ROHS3 compliance, ensuring regulatory alignment and ongoing availability.

Engineering Selection Recommendations

The LCA1/0-56-X serves as the direct active equivalent for the obsolete LCAS1/0-56-X. Both parts are manufactured by Panduit Corp within the Pan-Lug™ series and maintain identical electrical and mechanical specifications for 1/0 AWG wire gauge applications with 5/16 stud connections.

Selection of LCA1/0-56-X is supported by its active product status, ensuring continued availability and supply chain reliability. The part maintains full ROHS3 compliance and carries identical regulatory classifications (EAR99, HTSUS 8536.90.4000), confirming regulatory equivalence.

The 0.280" (7.11mm) increase in overall length from the main part does not compromise electrical performance or mechanical compatibility with standard 5/16 stud mounting configurations. This dimensional difference reflects design evolution within the Pan-Lug™ series while preserving all critical functional parameters.

Frequently Asked Questions (FAQ)

Q: Can LCA1/0-56-X directly replace LCAS1/0-56-X in existing applications?

A: Yes. Both parts maintain identical wire gauge (1/0 AWG), stud size (5/16), terminal type (rectangular tongue), barrel dimensions, and contact specifications. The increased overall length of LCA1/0-56-X does not affect electrical performance or mechanical compatibility with 5/16 stud connections.

Q: What is the significance of the length difference between these parts?

A: LCAS1/0-56-X measures 1.720" (43.69mm) overall length while LCA1/0-56-X measures 2.000" (50.80mm). This 0.280" difference reflects design iteration within the Pan-Lug™ series. The longer dimension does not impact electrical characteristics or stud connection compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both LCAS1/0-56-X and LCA1/0-56-X are ROHS3 compliant, confirming regulatory equivalence for applications requiring RoHS certification.

Q: What termination method applies to both parts?

A: Both parts utilize crimp barrel termination for 1/0 AWG wire. Barrel dimensions are identical: 0.390" (9.91mm) inner diameter and 0.520" (13.21mm) outer diameter.

Q: Why is LCAS1/0-56-X classified as obsolete?

A: LCAS1/0-56-X is obsolete, while LCA1/0-56-X maintains active status. LCA1/0-56-X represents the current production equivalent within the Pan-Lug™ series and should be specified for new designs and replacement applications.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts feature copper contact material with electro-tin finish, ensuring identical electrical conductivity and corrosion resistance characteristics.

Q: What is the packaging configuration?

A: Both parts are supplied in bulk packaging, suitable for high-volume assembly and integration applications.
