LCAF4-10-L Equivalent & Substitute Parts

Part Overview

The LCAF4-10-L is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4 AWG wire gauge applications with a #10 stud connection. This component is classified as a non-insulated, crimp barrel terminal featuring electro-tin plated copper contacts. The LCAF4-10-L is currently listed as obsolete, necessitating identification of active equivalent components to maintain supply chain continuity for applications requiring this terminal specification.

Engineering Selection Recommendations

The LCAX4-10-L is the direct substitute for the obsolete LCAF4-10-L. Both components maintain identical electrical and mechanical specifications across all critical parameters that determine terminal compatibility: wire gauge, stud size, termination method, contact material, and contact finish.

The LCAX4-10-L offers the advantage of active product status, ensuring ongoing availability and supply chain reliability. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

The primary dimensional difference between the two parts is the overall length (LCAF4-10-L: 1.540" versus LCAX4-10-L: 1.260") and barrel outer diameter (LCAF4-10-L: 0.460" versus LCAX4-10-L: 0.380"). These dimensional variations do not affect the functional compatibility of the terminal for standard 4 AWG wire applications with #10 stud connections.

Frequently Asked Questions (FAQ)

Q: Can LCAX4-10-L be used as a direct replacement for LCAF4-10-L?

A: Yes. The LCAX4-10-L is electrically and mechanically compatible with the LCAF4-10-L. Both components share identical wire gauge (4 AWG), stud size (#10), termination method (crimp barrel), contact material (copper), and contact finish (electro-tin) specifications.

Q: What is the difference between LCAF4-10-L and LCAX4-10-L?

A: The primary differences are product status and physical dimensions. The LCAF4-10-L is obsolete, while the LCAX4-10-L is active. The LCAF4-10-L has an overall length of 1.540" and barrel outer diameter of 0.460", while the LCAX4-10-L measures 1.260" in length and 0.380" in barrel outer diameter. These dimensional differences do not affect electrical performance or compatibility with 4 AWG wire and #10 stud applications.

Q: Are both parts compliant with current regulations?

A: Yes. Both LCAF4-10-L and LCAX4-10-L are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and distribution.

Q: What wire gauge and stud size do these terminals accommodate?

A: Both terminals are designed for 4 AWG wire gauge with #10 stud connections. The barrel inner diameter is 0.280" (7.11mm) and the ring inner diameter is 0.200" (5.08mm) for both components.

Q: What termination method is used for these terminals?

A: Both components use crimp barrel termination, requiring a crimping tool suitable for 4 AWG wire and barrel-style connections.

Q: Are these terminals insulated?

A: No. Both LCAF4-10-L and LCAX4-10-L are non-insulated terminals. Insulation must be provided separately if required by the application.
