LCD300-38DF-X Equivalent & Substitute Parts

Part Overview

The LCD300-38DF-X is a rectangular tongue terminal connector manufactured by Panduit Corp, rated for 300MCM (kcmil) wire gauge with a 3/8 stud connection. This component is classified as obsolete, indicating discontinuation from active production. The terminal features a non-insulated copper construction with electro-tin contact finish, designed for crimp barrel termination in free-hanging, right-angle mounting configurations.

Due to its obsolete status, identifying equivalent substitute parts is necessary for ongoing maintenance, repair, and system continuity in applications requiring this terminal specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCD300-38DF-X is determined by strict equivalence across the following critical parameters:

Wire Gauge Compatibility: The substitute part must accommodate 300MCM (kcmil) conductor cross-section.

Stud/Tab Specification: The 3/8 stud size must be maintained for mechanical and electrical connection integrity.

Terminal Geometry: Rectangular tongue configuration with two stud holes ensures proper mounting and load distribution.

Electrical Properties: Copper contact material with electro-tin finish provides equivalent conductivity and corrosion resistance.

Mechanical Dimensions: Barrel inner diameter (0.650"), barrel outer diameter (0.810"), and ring inner diameter (0.410") must remain constant for crimp tool compatibility and connection reliability.

Termination Process: Crimp barrel termination method requires identical barrel geometry and material composition.

The LCD300-38D-X qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction between the main part and substitute relates to product status (obsolete versus active) and packaging configuration (unspecified versus bulk), not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LCD300-38D-X is the direct equivalent substitute for the obsolete LCD300-38DF-X. Both components share identical electrical and mechanical specifications across all critical parameters that determine functional compatibility.

Product Status Consideration: The LCD300-38D-X maintains active production status, ensuring availability for procurement and supply chain continuity. The LCD300-38DF-X, classified as obsolete, is no longer manufactured by Panduit Corp.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. Export classification (EAR99) and tariff codes (HTSUS 8536.90.4000) are identical.

Inventory Availability: The LCD300-38D-X is available in bulk packaging with 813 pieces in stock, compared to 717 pieces of the obsolete variant. This availability differential supports transition planning for applications currently utilizing the LCD300-38DF-X.

Functional Equivalence: All electrical properties, mechanical dimensions, and termination characteristics are identical. Direct substitution is supported without modification to existing assembly processes, tooling, or installation procedures.

Frequently Asked Questions (FAQ)

Q: Can the LCD300-38D-X be used as a direct replacement for the LCD300-38DF-X?

A: Yes. The LCD300-38D-X is a direct functional equivalent. All electrical specifications, mechanical dimensions, contact materials, and termination methods are identical. The primary difference is product status (active versus obsolete) and packaging configuration.

Q: What are the critical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: wire gauge (300MCM), stud size (3/8), terminal type (rectangular tongue), barrel dimensions (0.650" ID, 0.810" OD), ring diameter (0.410" ID), tab thickness (0.160"), contact material (copper), contact finish (electro-tin), and termination method (crimp barrel).

Q: Are there any differences in mounting configuration between these parts?

A: The LCD300-38DF-X specifies both free-hanging in-line and right-angle mounting, while the LCD300-38D-X specifies free-hanging in-line mounting. Both support the same crimp barrel termination process and stud connection interface.

Q: Does the overall length difference affect substitution?

A: The LCD300-38D-X has a specified overall length of 3.740" (95.00mm), while the LCD300-38DF-X length is not specified. This dimensional specification does not affect electrical or mechanical compatibility for terminal connection purposes.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the LCD300-38DF-X and LCD300-38D-X are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the significance of the packaging difference?

A: The LCD300-38D-X is supplied in bulk packaging, while the LCD300-38DF-X packaging is unspecified. Bulk packaging typically accommodates higher-volume procurement and inventory management requirements without affecting component performance or specifications.

Q: Can existing crimp tools be used with the LCD300-38D-X?

A: Yes. Identical barrel geometry (0.650" ID, 0.810" OD) ensures compatibility with existing crimp tooling designed for the LCD300-38DF-X.
