LCDX4-14D-L Equivalent & Substitute Parts

Part Overview

The LCDX4-14D-L is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4 AWG wire gauge applications with a 1/4 inch stud connection. This non-insulated copper terminal features electro-tin contact finish and is rated for crimp barrel termination. The part is classified 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 LCDX4-14D-L is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part LCDX4-14A-L maintains identical specifications for wire gauge, stud size, terminal type, termination method, contact material, contact finish, insulation status, barrel dimensions, ring ID, tab thickness, terminal style, and mounting type. Both parts are members of the Pan-Lug™ series and share the same base product number LCDX.

The primary distinction between these parts is overall length: the LCDX4-14D-L measures 2.350 inches (59.69mm), while the LCDX4-14A-L measures 1.980 inches (50.30mm). This dimensional difference does not affect the core electrical or mechanical connection characteristics, as both terminals accommodate the same wire gauge and stud configuration. The substitute part carries active product status with current manufacturing availability, whereas the main part is obsolete.

Engineering Selection Recommendations

The LCDX4-14A-L serves as the direct functional equivalent to the obsolete LCDX4-14D-L for applications requiring 4 AWG rectangular tongue terminals with 1/4 inch stud connections. Both parts maintain identical electrical and mechanical connection specifications, including barrel dimensions, ring ID, contact material, and termination method.

The LCDX4-14A-L is the recommended selection for new designs and ongoing production requirements due to its active product status and current manufacturing availability. Both parts satisfy ROHS3 compliance and REACH unaffected regulatory requirements, ensuring compatibility with current environmental and safety standards.

The dimensional difference in overall length (0.370 inches shorter for the LCDX4-14A-L) should be evaluated within the specific application context to confirm spatial compatibility. This length variation does not alter the electrical performance or mechanical connection integrity of the terminal.

Frequently Asked Questions (FAQ)

Q: Can LCDX4-14A-L directly replace LCDX4-14D-L in existing applications?

A: The LCDX4-14A-L maintains identical electrical and mechanical connection specifications for wire gauge, stud size, barrel dimensions, and termination method. The primary difference is overall length. Confirmation of spatial clearance in the application is necessary before substitution.

Q: What is the significance of the length difference between these parts?

A: The LCDX4-14D-L measures 2.350 inches overall length, while the LCDX4-14A-L measures 1.980 inches. This 0.370-inch difference does not affect the electrical connection or mechanical interface with the 1/4 inch stud. Applications with space constraints may benefit from the shorter LCDX4-14A-L.

Q: Are both parts compliant with current environmental regulations?

A: Both LCDX4-14D-L and LCDX4-14A-L are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards.

Q: Why is LCDX4-14D-L classified as obsolete?

A: The LCDX4-14D-L is obsolete, indicating discontinued manufacturing. The LCDX4-14A-L remains in active production and is the current equivalent offering from Panduit Corp for this terminal specification.

Q: What packaging options are available for the substitute part?

A: The LCDX4-14A-L is supplied in bulk packaging, with 1258 pieces currently in stock.

Q: Are the contact finish and material identical between both parts?

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

Q: What termination method is used for both terminals?

A: Both LCDX4-14D-L and LCDX4-14A-L utilize crimp barrel termination for 4 AWG wire connections.
