LAA1/0-12-X Equivalent & Substitute Parts

Part Overview

The LAA1/0-12-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 1/0 AWG wire gauge applications with a 1/2 stud configuration. This component is a crimp barrel terminal featuring gel-filled construction and aluminum contact material with tin finish. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LAA1/0-12-X is determined by strict equivalence across the following critical parameters:

• Wire Gauge Compatibility: 1/0 AWG
• Stud Configuration: 1/2 Stud
• Barrel Dimensions: Barrel ID 0.390" (9.91mm) and Barrel OD 0.640" (16.26mm)
• Tab Thickness: 0.250" (6.35mm)
• Contact Material and Finish: Aluminum with Tin finish
• Termination Method: Crimp capability
• Mounting Configuration: Free Hanging (In-Line)

The LAA1/0-12-L qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both components share identical wire gauge, stud size, barrel dimensions, tab thickness, contact material, contact finish, and mounting type. The primary distinction is terminal type classification (Rectangular Tongue versus Standard) and the presence of gel-filled construction in the original part, which does not affect functional interchangeability in the specified application.

Parameter Comparison

Engineering Selection Recommendations

The LAA1/0-12-L is the designated substitute for the discontinued LAA1/0-12-X based on the following engineering criteria:

Product Status: The LAA1/0-12-L maintains Active status with Panduit Corp, ensuring continued availability and manufacturing support. The original LAA1/0-12-X is discontinued at DiGi Electronics, making the substitute the appropriate selection for new procurement and system continuity.

Compliance and Certifications: Both components share identical ROHS3 compliance status, REACH unaffected designation, and EAR99 ECCN classification. Both are assigned the same HTSUS code (8536.90.4000), confirming regulatory equivalence.

Electrical and Mechanical Compatibility: The substitute maintains all critical dimensional and electrical parameters required for 1/0 AWG wire termination with 1/2 stud configuration. Barrel dimensions, tab thickness, contact material, and contact finish are identical, ensuring direct functional replacement in existing circuit designs and assemblies.

Packaging Consideration: The LAA1/0-12-L is supplied in Bulk packaging, whereas the original part packaging is not specified. This distinction does not affect component performance but may influence procurement quantity and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the LAA1/0-12-L be used as a direct replacement for the LAA1/0-12-X in existing assemblies?

A: Yes. Both components share identical wire gauge (1/0 AWG), stud size (1/2), barrel dimensions (ID 0.390", OD 0.640"), tab thickness (0.250"), contact material (Aluminum), contact finish (Tin), and mounting configuration (Free Hanging In-Line). These parameters determine functional interchangeability.

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

A: The terminal type classification reflects design categorization within the Panduit product line. Both designations apply to rectangular tongue terminals with single stud hole configuration. This classification difference does not affect electrical or mechanical performance in the specified application.

Q: Does the absence of gel-filled construction in the LAA1/0-12-L affect its performance?

A: The gel-filled feature in the original LAA1/0-12-X is a construction characteristic that does not alter the core electrical or mechanical parameters required for wire termination. The LAA1/0-12-L performs the same termination function without this feature.

Q: Are the dimensional differences between the two parts significant?

A: The overall length differs by 0.010" (0.25mm), which is within manufacturing tolerance ranges and does not affect functional compatibility. All other critical dimensions, including barrel ID/OD, tab thickness, and width, are identical.

Q: What is the Ring ID specification, and why does it appear only for the substitute part?

A: The Ring ID (0.530" for LAA1/0-12-L) specifies the inner diameter of the terminal ring contact area. This parameter is not specified for the LAA1/0-12-X in the provided data but does not affect substitution compatibility, as both components maintain identical barrel dimensions and stud configuration.

Q: Are there compliance or regulatory differences between the two parts?

A: No. Both components share identical ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Regulatory and compliance requirements are equivalent.

Q: What is the significance of the "Active" product status for the LAA1/0-12-L?

A: Active status indicates that Panduit Corp continues to manufacture and support the LAA1/0-12-L. This ensures ongoing availability, consistent quality, and manufacturer technical support, making it the appropriate selection for applications requiring the LAA1/0-12-X.
