LCAS8-56-L Equivalent & Substitute Parts

Part Overview

The LCAS8-56-L is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 8 AWG wire termination onto a 5/16 stud. This component is part of the Pan-Lug™ series and features a crimp barrel termination method with electro-tin plated copper contacts. The LCAS8-56-L is classified as obsolete, necessitating identification of active equivalent parts to maintain supply chain continuity and ensure design compatibility in applications requiring this terminal specification.

Substitute Part Grouping Explanation

Substitution of the LCAS8-56-L is determined by strict equivalence across the following critical parameters:

Wire gauge compatibility (8 AWG) ensures proper barrel diameter and crimp characteristics. The stud size (5/16) is non-negotiable for mechanical fit on the receiving component. Terminal type (rectangular tongue) and termination method (crimp, barrel) define the functional interface. Barrel dimensions (ID 0.180", OD 0.270") and ring ID (0.340") establish the physical envelope and electrical contact area. Contact material (copper) and finish (electro-tin) determine electrical conductivity and corrosion resistance. Tab thickness (0.050") and insulation status (non-insulated) are fixed design parameters. RoHS3 compliance is required for regulatory equivalence.

The substitute part LCA8-56-L maintains all critical parameters within these specifications, with the exception of overall length, which differs due to manufacturing design evolution while preserving functional compatibility.

Engineering Selection Recommendations

The LCA8-56-L is the direct active equivalent for the obsolete LCAS8-56-L. Both components are manufactured by Panduit Corp within the Pan-Lug™ series and maintain identical electrical and mechanical specifications across all critical parameters: wire gauge (8 AWG), stud size (5/16), barrel dimensions, contact material and finish, and RoHS3 compliance.

The LCA8-56-L differs only in overall length (1.460" versus 1.320"), which reflects manufacturing design evolution. This dimensional difference does not affect functional compatibility in applications where the terminal is crimped to 8 AWG wire and mounted on a 5/16 stud, as the critical contact interface dimensions remain unchanged.

The LCA8-56-L is currently in active production with 1942 units in stock, compared to 995 units of the obsolete LCAS8-56-L. Selection of the LCA8-56-L ensures continued supply availability and maintains full regulatory compliance through ROHS3 certification and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the LCA8-56-L replace the LCAS8-56-L in existing designs?

A: Yes. The LCA8-56-L is functionally equivalent for all applications requiring an 8 AWG rectangular tongue terminal with 5/16 stud connection. The wire gauge, stud size, barrel dimensions, and contact specifications are identical. The increased overall length (1.460" versus 1.320") does not affect the crimp connection or stud interface.

Q: What is the significance of the overall length difference?

A: The overall length difference (0.140" or 3.55mm) reflects design updates in the active product line. This dimension does not impact the electrical connection or mechanical fit at the crimp barrel or stud interface, which are determined by barrel ID/OD and ring ID specifications that remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the LCAS8-56-L and LCA8-56-L are ROHS3 compliant. The LCA8-56-L additionally carries REACH unaffected status, confirming regulatory alignment with current environmental standards.

Q: Why is the LCAS8-56-L listed as obsolete?

A: The LCAS8-56-L has been superseded by the LCA8-56-L in Panduit's active product portfolio. The LCA8-56-L provides equivalent functionality with updated design specifications and is the recommended selection for new designs and replenishment orders.

Q: Are the contact specifications identical between both parts?

A: Yes. Both parts feature copper contacts with electro-tin finish, identical barrel dimensions (0.180" ID, 0.270" OD), and identical ring ID (0.340"). These specifications ensure equivalent electrical performance and corrosion resistance.

Q: What is the packaging format for both parts?

A: Both the LCAS8-56-L and LCA8-56-L are supplied in bulk packaging, suitable for high-volume assembly operations and component inventory management.
