LCAS1/0-12-X Equivalent & Substitute Parts

Part Overview

The LCAS1/0-12-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 1/0 AWG wire gauge applications with a 1/2 stud connection. This non-insulated copper terminal features electro-tin contact finish and is rated for crimp barrel termination. The product is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this terminal specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCAS1/0-12-X is determined by the following critical parameters:

Wire Gauge Compatibility: The substitute must accommodate 1/0 AWG wire to ensure proper barrel crimp engagement and electrical conductivity.

Stud/Tab Size Alignment: The 1/2 stud dimension is mandatory for mechanical mounting compatibility with the receiving assembly.

Ring ID Specification: The ring ID of 0.530" (13.46mm) establishes the stud hole diameter requirement and must remain constant across substitutes.

Termination Method: Crimp barrel termination is the required connection method; substitutes must support this termination type.

Contact Material and Finish: Copper with electro-tin finish ensures corrosion resistance and electrical performance consistency.

Regulatory Compliance: ROHS3 compliance is required for all substitute parts to meet current environmental standards.

The substitute part LCA1/0-12-X meets all critical substitution criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The LCA1/0-12-X terminal connector is the appropriate substitute for the obsolete LCAS1/0-12-X based on the following engineering criteria:

Regulatory Compliance: Both parts maintain ROHS3 compliance, ensuring compatibility with current environmental and procurement standards.

Product Status: The LCA1/0-12-X holds active product status with confirmed inventory availability (1102 pcs), whereas the LCAS1/0-12-X is obsolete with limited remaining stock (1166 pcs). Active status ensures long-term supply chain reliability and manufacturer support.

Critical Dimensional Alignment: The ring ID of 0.530" (13.46mm) is identical across both parts, confirming mechanical compatibility with existing stud assemblies. Wire gauge (1/0 AWG) and stud size (1/2) are matched specifications.

Electrical Performance: Identical contact material (copper) and finish (electro-tin) ensure equivalent electrical conductivity and corrosion resistance characteristics.

Termination Compatibility: Both parts utilize crimp barrel termination, allowing use of existing crimping equipment and procedures without modification.

Physical Differences: The LCA1/0-12-X exhibits increased barrel dimensions (ID: 0.390" vs. 0.360"; OD: 0.520" vs. 0.470") and greater tab thickness (0.120" vs. 0.090"), providing enhanced mechanical robustness. Overall length and width are proportionally increased. These dimensional changes do not compromise substitution eligibility when the receiving assembly accommodates the larger envelope.

Frequently Asked Questions (FAQ)

Q: Can the LCA1/0-12-X directly replace the LCAS1/0-12-X in existing assemblies?

A: Direct replacement is possible when the receiving assembly accommodates the larger physical envelope of the LCA1/0-12-X. The critical dimension—ring ID of 0.530" (13.46mm)—is identical, ensuring stud hole compatibility. Verify that the assembly cavity can accept the increased overall length (2.310" vs. 1.940") and width (0.800" vs. 0.750") before implementation.

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

A: No. The barrel ID and OD differ between the parts. The LCAS1/0-12-X has a barrel ID of 0.360" and OD of 0.470", while the LCA1/0-12-X has a barrel ID of 0.390" and OD of 0.520". These dimensional differences require use of the appropriate crimping tool and die set for each part number. Verify crimping equipment compatibility before substitution.

Q: Do both parts support the same wire gauge and termination method?

A: Yes. Both the LCAS1/0-12-X and LCA1/0-12-X are rated for 1/0 AWG wire and utilize crimp barrel termination. Existing crimping procedures and wire preparation specifications remain applicable to the substitute part.

Q: What is the significance of the increased tab thickness in the LCA1/0-12-X?

A: The tab thickness increase from 0.090" to 0.120" provides greater mechanical strength and load-bearing capacity. This enhancement does not affect electrical performance but improves durability in high-vibration or high-stress applications. The thicker tab is compatible with standard 1/2 stud assemblies.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry identical regulatory classifications (ECCN: EAR99; HTSUS: 8536.90.4000). No compliance barriers exist for substitution. The LCA1/0-12-X includes documented REACH Unaffected status, providing additional regulatory clarity.

Q: Why is the LCA1/0-12-X classified as active while the LCAS1/0-12-X is obsolete?

A: Product status reflects manufacturer support and production continuity. The LCAS1/0-12-X has been discontinued, with no new production planned. The LCA1/0-12-X remains in active production with confirmed inventory and ongoing manufacturer support, making it the preferred choice for new designs and long-term supply chain planning.

Q: Can I use the same crimping tool for both part numbers?

A: No. The different barrel dimensions require different crimping dies. Verify that your crimping equipment includes the appropriate die set for the LCA1/0-12-X (barrel ID: 0.390") before substitution. Using incorrect dies will result in improper termination and potential electrical failure.
