LCAS4/0-12H-X Equivalent & Substitute Parts

Part Overview

The LCAS4/0-12H-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4/0 AWG wire gauge applications with a 1/2 stud connection. This component is classified as a Pan-Lug™ series terminal and features crimp barrel termination with electro-tin contact finish on copper material. The part is currently listed 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 LCAS4/0-12H-X is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for wire gauge (4/0 AWG), stud size (1/2), terminal type (rectangular tongue), termination method (crimp barrel), and all dimensional characteristics including barrel inner diameter (0.570"), barrel outer diameter (0.710"), and ring inner diameter (0.530"). Contact material, finish type, and insulation status must remain unchanged. Compliance certifications including RoHS3 status must be maintained. The substitute part LCA4/0-12H-X meets all these criteria and is classified as an active product, providing direct functional and mechanical compatibility with the obsolete LCAS4/0-12H-X.

Engineering Selection Recommendations

The LCA4/0-12H-X serves as the direct active equivalent for the obsolete LCAS4/0-12H-X. All electrical and mechanical parameters are identical across both parts, ensuring complete functional compatibility. The substitute part maintains ROHS3 compliance and carries identical export classification (EAR99) and tariff codes (8536.90.4000). The transition from obsolete to active product status provides improved supply chain availability, with 1160 units currently in stock compared to the legacy part's inventory position. Selection of LCA4/0-12H-X eliminates obsolescence risk while preserving all performance characteristics required for 4/0 AWG rectangular tongue terminal applications with 1/2 stud connections.

Frequently Asked Questions (FAQ)

Q: Can LCA4/0-12H-X be used as a direct replacement for LCAS4/0-12H-X?

A: Yes. The LCA4/0-12H-X is a direct equivalent with identical electrical and mechanical specifications. All dimensional parameters, wire gauge rating, stud size, termination method, and material composition are unchanged.

Q: Are there any dimensional differences between these parts?

A: No. Both parts share identical dimensions: 0.140" tab thickness, 1.060" outer width, 0.570" barrel inner diameter, 0.710" barrel outer diameter, and 0.530" ring inner diameter.

Q: What is the primary advantage of switching to LCA4/0-12H-X?

A: The LCA4/0-12H-X is classified as an active product with confirmed inventory availability (1160 units in stock), whereas LCAS4/0-12H-X is obsolete. This transition eliminates supply chain discontinuity.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry EAR99 export classification, and share identical HTSUS tariff code 8536.90.4000.

Q: Is the packaging different between these parts?

A: The LCAS4/0-12H-X packaging is not specified in available documentation. The LCA4/0-12H-X is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Are the contact materials and finishes identical?

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

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes. The identical stud size (1/2), terminal type (rectangular tongue), and mounting configuration (free hanging, 45° angle) ensure mechanical and electrical interchangeability in all applications designed for LCAS4/0-12H-X.
