LAA4/0-38-5 Equivalent & Substitute Parts

Part Overview

The LAA4/0-38-5 is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4/0 AWG wire gauge applications with a 3/8 inch stud connection. This component is classified as a crimp barrel terminal with gel-filled construction and tin contact finish on aluminum material. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain supply chain continuity for applications requiring this terminal specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAA4/0-38-5 is determined by strict alignment of the following critical parameters:

Wire Gauge Compatibility: The substitute part must support 4/0 AWG wire gauge to ensure proper current-carrying capacity and mechanical fit within the crimp barrel.

Stud/Tab Size: The substitute must feature a 3/8 inch stud to maintain mechanical compatibility with the mating connector or bus bar assembly.

Terminal Type and Style: The substitute must be a rectangular tongue terminal with a single stud hole configuration to preserve the mounting interface.

Termination Method: The substitute must utilize crimp barrel termination to ensure compatibility with existing assembly equipment and procedures.

Contact Material and Finish: The substitute must maintain aluminum contact material with tin finish to preserve electrical conductivity and corrosion resistance characteristics.

Insulation Status: The substitute must be non-insulated to match the original specification.

The LAA4/0-38-30 meets all these critical parameters and is identified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The LAA4/0-38-30 is the appropriate substitute for the discontinued LAA4/0-38-5 based on the following engineering criteria:

Functional Equivalence: Both parts share identical wire gauge (4/0 AWG), stud size (3/8 inch), barrel dimensions, and mounting configuration. The electrical and mechanical interfaces are fully compatible.

Product Status: The LAA4/0-38-30 maintains active product status with Panduit Corp, ensuring continued availability and supply chain reliability. The LAA4/0-38-5 is discontinued, making the substitute necessary for ongoing procurement.

Compliance and Certifications: Both parts are classified under the same HTSUS code (8536.90.4000) and ECCN (EAR99), confirming regulatory equivalence. The LAA4/0-38-5 is confirmed ROHS3 compliant.

Minor Specification Differences: The LAA4/0-38-30 features a tab thickness of 0.310" (7.87mm) compared to 0.320" (8.13mm) on the main part, representing a 0.010" reduction. The substitute includes a ring ID diameter of 0.410" (10.41mm), which is not specified for the main part. The LAA4/0-38-5 includes gel-filled construction, while the LAA4/0-38-30 does not specify this feature. These differences do not affect functional compatibility in standard 4/0 AWG terminal applications.

Inventory Availability: The LAA4/0-38-30 is available with 967 pieces in stock, providing immediate procurement capability.

Frequently Asked Questions (FAQ)

Q: Can the LAA4/0-38-30 be used as a direct replacement for the LAA4/0-38-5?

A: Yes. Both parts are 4/0 AWG rectangular tongue terminals with 3/8 inch studs, identical barrel dimensions, and crimp termination. The electrical and mechanical interfaces are fully compatible. The LAA4/0-38-30 is the manufacturer-recommended substitute.

Q: What is the difference between the "Rectangular Tongue" and "Standard" terminal type designations?

A: The terminal type designation reflects the specific terminal configuration. Both the LAA4/0-38-5 (Rectangular Tongue) and LAA4/0-38-30 (Standard) are rectangular tongue terminals with single stud hole mounting. The designation difference does not indicate functional incompatibility.

Q: Does the 0.010" difference in tab thickness affect performance?

A: The tab thickness difference (0.320" versus 0.310") does not affect electrical performance or mechanical compatibility in standard 4/0 AWG applications. Both thicknesses are within acceptable ranges for this wire gauge and stud size combination.

Q: Why does the LAA4/0-38-5 specify gel-filled construction while the LAA4/0-38-30 does not?

A: Gel-filled construction is a feature specification that does not affect the core electrical or mechanical compatibility of the terminal. The LAA4/0-38-30 provides equivalent performance for standard 4/0 AWG crimp barrel applications.

Q: What packaging is available for the LAA4/0-38-30?

A: The LAA4/0-38-30 is supplied in bulk packaging, as opposed to the unspecified packaging for the discontinued LAA4/0-38-5.

Q: Are both parts RoHS compliant?

A: The LAA4/0-38-5 is confirmed ROHS3 compliant. RoHS compliance status for the LAA4/0-38-30 is not specified in the available data.

Q: What is the ring ID specification on the LAA4/0-38-30?

A: The LAA4/0-38-30 specifies a ring ID diameter of 0.410" (10.41mm). This dimension is not provided for the LAA4/0-38-5 but does not affect substitution compatibility.
