LCAS2-56H-Q Equivalent & Substitute Parts

Part Overview

The LCAS2-56H-Q is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 2 AWG wire termination on a 5/16 stud. This component is classified as a Pan-Lug™ series terminal with crimp barrel termination and electro-tin contact finish. 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 LCAS2-56H-Q is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for wire gauge, stud size, terminal geometry, barrel dimensions, and contact properties to ensure functional compatibility within existing circuit designs and assembly processes.

The following parameters establish substitution validity:

Wire Gauge: 2 AWG (determines current-carrying capacity and wire compatibility)
Stud/Tab Size: 5/16 Stud (determines mounting interface compatibility)
Terminal Type: Rectangular Tongue (determines mechanical form factor)
Termination Method: Crimp, Barrel (determines assembly process compatibility)
Barrel Dimensions: ID 0.310" / OD 0.420" (determines crimp tool compatibility)
Ring ID: 0.340" (determines stud fit tolerance)
Contact Material and Finish: Copper with Electro-Tin (determines electrical performance and corrosion resistance)
Tab Thickness: 0.100" (determines mechanical strength and insertion force)

Engineering Selection Recommendations

The LCA2-56H-Q is the direct active equivalent for the obsolete LCAS2-56H-Q. All electrical and mechanical parameters are identical across both parts. The LCA2-56H-Q maintains ROHS3 compliance and carries REACH Unaffected status, meeting current regulatory requirements. The substitute part is manufactured by the same supplier (Panduit Corp) within the same Pan-Lug™ series, ensuring design continuity and manufacturing consistency.

Selection of LCA2-56H-Q for applications previously specified with LCAS2-56H-Q requires no design modification or re-qualification. The active product status of LCA2-56H-Q ensures continued availability and supply chain stability compared to the obsolete LCAS2-56H-Q designation.

Frequently Asked Questions (FAQ)

Q: Can LCA2-56H-Q be used as a direct replacement for LCAS2-56H-Q?

A: Yes. LCA2-56H-Q is a direct functional equivalent. All critical parameters including wire gauge, stud size, barrel dimensions, contact material, and contact finish are identical. No design changes are required.

Q: Are there any differences in electrical performance between these parts?

A: No. Both parts use copper with electro-tin contact finish, identical barrel dimensions (0.310" ID / 0.420" OD), and equivalent ring ID (0.340"). Electrical performance characteristics are identical.

Q: What is the primary reason for substitution?

A: The LCAS2-56H-Q is classified as obsolete. The LCA2-56H-Q is the active equivalent part that maintains full compatibility while ensuring ongoing availability.

Q: Are both parts RoHS compliant?

A: Yes. Both LCAS2-56H-Q and LCA2-56H-Q are ROHS3 compliant. The LCA2-56H-Q additionally carries REACH Unaffected status.

Q: Will existing crimp tooling work with the substitute part?

A: Yes. The barrel dimensions are identical (0.310" ID / 0.420" OD), ensuring compatibility with existing crimp tools and assembly processes.

Q: Is the tab thickness the same on both parts?

A: Yes. Both parts have a tab thickness of 0.100" (2.54mm), maintaining identical mechanical strength and insertion force characteristics.

Q: Can these parts be intermixed in inventory?

A: Yes. The parts are functionally identical and can be used interchangeably. However, maintaining separate inventory records is recommended to track product status and ensure traceability.
