LAB1000-12-1 Equivalent & Substitute Parts

Part Overview

The LAB1000-12-1 is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 1000MCM (kcmil) wire gauge applications with a 1/2 stud configuration. This component is classified as a crimp barrel terminal with gel-filled construction and aluminum contact material finished in tin. 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 of the LAB1000-12-1 is determined by strict equivalence across the following critical parameters:

Wire Gauge Compatibility: Both the main part and substitute must accommodate 1000MCM (kcmil) wire gauge to ensure proper current-carrying capacity and mechanical fit within the barrel crimp area.

Stud/Tab Size: The 1/2 stud configuration must be maintained to ensure mechanical compatibility with mating hardware and assembly fixtures.

Contact Material and Finish: Aluminum contact material with tin finish must be preserved to maintain electrical conductivity and corrosion resistance characteristics.

Barrel Dimensions: The barrel inner diameter (ID) of 1.190" (30.23mm) and outer diameter (OD) of 1.840" (46.74mm) are critical for wire insertion and crimp tool compatibility.

Termination Method: Crimp barrel termination is the required connection method for this application category.

Mounting Configuration: Free hanging (in-line) mounting type ensures proper installation orientation and mechanical support.

The LAB1000-12-8 substitute part maintains equivalence across all these critical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The LAB1000-12-8 is the manufacturer-recommended substitute for the discontinued LAB1000-12-1. Both parts share identical wire gauge (1000MCM), stud size (1/2), barrel dimensions (1.190" ID × 1.840" OD), contact material (aluminum), and contact finish (tin). The substitute maintains the same mounting configuration (free hanging in-line) and termination method (crimp barrel).

The primary distinction between the parts is product status: LAB1000-12-1 is discontinued, while LAB1000-12-8 is active with current inventory availability (740 pieces in stock). The LAB1000-12-8 features a standard terminal type configuration compared to the rectangular tongue designation of the main part, with a minor overall length difference of 0.060" (1.52mm), which falls within typical mechanical tolerance ranges for this component category.

Both parts comply with export control classification (EAR99) and share the same HTSUS commodity code (8536.90.4000), confirming regulatory equivalence. The LAB1000-12-8 is suitable for direct substitution in applications currently specified for LAB1000-12-1.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if LAB1000-12-8 can substitute for LAB1000-12-1?

A: The critical parameters are wire gauge (1000MCM), stud size (1/2), barrel inner diameter (1.190"), barrel outer diameter (1.840"), contact material (aluminum), contact finish (tin), and termination method (crimp). The LAB1000-12-8 maintains equivalence across all these parameters.

Q: Are there dimensional differences between LAB1000-12-1 and LAB1000-12-8?

A: The overall length differs by 0.060" (1.52mm): LAB1000-12-1 measures 9.670" (245.62mm) while LAB1000-12-8 measures 9.730" (247.14mm). The width (2.560"), tab thickness (0.630"), and all barrel dimensions remain identical. This minor length variation is within standard mechanical tolerance ranges for terminal connectors.

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

A: The terminal type designation reflects the connector configuration. Both LAB1000-12-1 (rectangular tongue) and LAB1000-12-8 (standard) maintain the same two stud hole configuration, barrel dimensions, and functional electrical characteristics required for 1000MCM wire termination.

Q: Why is LAB1000-12-1 discontinued?

A: Product discontinuation is a manufacturer decision typically driven by market demand, product line consolidation, or transition to improved designs. The LAB1000-12-8 represents the active equivalent in the Panduit LAB series for this wire gauge and stud size combination.

Q: Are both parts RoHS compliant?

A: LAB1000-12-1 is explicitly ROHS3 compliant. RoHS status for LAB1000-12-8 is not specified in the available documentation. Both parts are classified as EAR99 for export control purposes.

Q: Can LAB1000-12-8 be used in existing assemblies designed for LAB1000-12-1?

A: Yes. The LAB1000-12-8 maintains mechanical and electrical equivalence across all critical parameters: wire gauge, stud size, barrel dimensions, contact material, and termination method. The 0.060" length difference does not affect functional compatibility in standard mounting configurations.

Q: What is the current inventory status for these parts?

A: LAB1000-12-1 has 906 pieces in stock but is discontinued. LAB1000-12-8 has 740 pieces in stock and is an active product with ongoing availability.
