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

Part Overview

The LCAS4/0-12F-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4/0 AWG wire termination with a 1/2 stud connection. This component is classified as obsolete, indicating discontinuation from active production. The part is a non-insulated, crimp-barrel terminal with electro-tin contact finish and copper contact material, suitable for high-amperage electrical applications requiring reliable mechanical and electrical connections.

Due to its obsolete status, locating equivalent substitute parts is necessary for ongoing maintenance, repair, and system continuity. Active production alternatives with identical electrical and mechanical specifications are available to ensure uninterrupted component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCAS4/0-12F-X is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Wire Gauge Compatibility: The substitute must accommodate 4/0 AWG wire exclusively, as this determines barrel diameter and crimp force requirements.

Terminal Geometry: The rectangular tongue configuration with 1/2 stud connection is non-negotiable for mechanical fit and electrical contact integrity.

Dimensional Specifications: Barrel inner diameter (0.570"), barrel outer diameter (0.710"), ring inner diameter (0.530"), and tab thickness (0.140") must be exact matches to ensure proper wire seating and stud engagement.

Contact Properties: Copper contact material with electro-tin finish ensures consistent electrical conductivity and corrosion resistance across equivalent parts.

Termination Method: Crimp-barrel termination is the sole acceptable method for this application category.

Compliance Standards: RoHS3 compliance is mandatory for regulatory alignment.

The substitute part LCA4/0-12F-X meets all these criteria and is classified as an active production component, providing direct functional and mechanical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The LCA4/0-12F-X is the direct equivalent substitute for the obsolete LCAS4/0-12F-X. Both components are manufactured by Panduit Corp within the Pan-Lug™ series and share identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The LCAS4/0-12F-X is obsolete, while the LCA4/0-12F-X maintains active production status. This distinction ensures long-term component availability and supply chain reliability for new installations and ongoing maintenance requirements.

Compliance Alignment: Both parts maintain ROHS3 compliance, satisfying regulatory requirements for electronic component procurement and deployment in regulated industries.

Inventory Availability: The substitute part LCA4/0-12F-X is currently available in stock (697 pieces), providing immediate procurement capability compared to the obsolete main part (1037 pieces remaining).

Packaging Consideration: The substitute is supplied in bulk packaging, which may require evaluation against specific procurement and storage requirements.

For applications requiring the LCAS4/0-12F-X specification, the LCA4/0-12F-X provides complete functional and mechanical interchangeability with the added benefit of active production support.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are identical in all critical electrical and mechanical parameters, including wire gauge (4/0 AWG), terminal geometry, dimensional specifications, contact material, and termination method. The LCA4/0-12F-X is the active production equivalent.

Q: What is the primary difference between these two part numbers?

A: The LCAS4/0-12F-X is classified as obsolete, while the LCA4/0-12F-X is in active production. The packaging differs (the substitute is supplied in bulk), but all functional specifications remain identical.

Q: Are there any dimensional incompatibilities between the main part and substitute?

A: No. All dimensional parameters are identical: barrel ID (0.570"), barrel OD (0.710"), ring ID (0.530"), tab thickness (0.140"), and outer width (1.060").

Q: Does the substitute maintain the same contact finish and material properties?

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

Q: Is the substitute RoHS3 compliant?

A: Yes. The LCA4/0-12F-X maintains ROHS3 compliance, matching the regulatory status of the main part.

Q: What wire gauge does this terminal accommodate?

A: Both the main part and substitute are designed exclusively for 4/0 AWG wire termination.

Q: Can these terminals be used in insulated applications?

A: No. Both parts are non-insulated terminals. Insulation must be applied separately if required by the application.

Q: What termination method is required for these terminals?

A: Both parts require crimp-barrel termination. The barrel diameter (0.570" ID) is sized specifically for 4/0 AWG wire and corresponding crimp tooling.
