LAB350-12-2 Equivalent & Substitute Parts

Part Overview

The LAB350-12-2 is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 350MCM (kcmil) wire gauge applications with a 1/2 stud configuration. This component is classified as obsolete, indicating it is no longer in active production. The terminal features a two stud hole design with a tin-plated aluminum contact material and gel-filled construction for enhanced reliability in harsh environments.

Due to its obsolete status, identifying equivalent substitute parts is necessary for ongoing maintenance, repair, and new design implementations where this connector type is specified. Active production alternatives with compatible electrical and mechanical parameters are available to ensure continuity of supply and system functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LAB350-12-2 with the LCCF350-12-6 is based on alignment of the following critical parameters:

Matched Parameters:

• Wire gauge: 350MCM (kcmil)
• Stud/Tab size: 1/2 Stud
• Terminal type: Rectangular Tongue
• Terminal style: Two Stud Holes
• Termination method: Crimp, Barrel
• Mounting type: Free Hanging (In-Line)
• Insulation: Non-Insulated
• Regulatory classification: REACH Unaffected, ECCN EAR99, HTSUS 8536.90.4000

The LCCF350-12-6 maintains functional equivalence for the primary electrical and mechanical interface requirements. Both connectors accommodate 350MCM wire gauge and feature identical stud configuration, terminal geometry classification, and termination approach. The substitute part is currently in active production status, ensuring availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The LCCF350-12-6 serves as the functional equivalent for the obsolete LAB350-12-2 based on matching electrical and mechanical interface specifications for 350MCM wire gauge applications with 1/2 stud termination.

Product Status Consideration: The LAB350-12-2 is obsolete and no longer manufactured. The LCCF350-12-6 is in active production status, ensuring long-term availability and supply chain reliability for new installations and replacement requirements.

Compliance Status: The LCCF350-12-6 carries ROHS3 compliance certification, whereas the LAB350-12-2 compliance status is not specified. Both parts maintain REACH Unaffected status and identical ECCN and HTSUS classifications, confirming regulatory alignment for export and trade purposes.

Physical and Electrical Compatibility: Both connectors accommodate identical wire gauge and stud configuration. Dimensional variations exist in tab thickness, overall length, and barrel diameters. These differences reflect design evolution within the product line while maintaining functional compatibility for the specified wire gauge and stud interface.

Contact Material Difference: The LAB350-12-2 features aluminum contacts with tin plating, while the LCCF350-12-6 uses copper contacts with electro-tin plating. Copper provides superior electrical conductivity and corrosion resistance compared to aluminum, representing an engineering improvement in the substitute design.

Frequently Asked Questions (FAQ)

Q: Can the LCCF350-12-6 directly replace the LAB350-12-2 in existing installations?

A: The LCCF350-12-6 maintains compatibility with the primary electrical and mechanical interface requirements. Both connectors accommodate 350MCM wire gauge and feature identical 1/2 stud configuration, rectangular tongue terminal type, and two stud hole design. Physical dimension variations exist; verify mounting clearances and assembly space constraints in your specific application before implementation.

Q: What is the primary reason for substitution?

A: The LAB350-12-2 is classified as obsolete and no longer in active production. The LCCF350-12-6 is the current active production equivalent, ensuring supply chain continuity and availability for maintenance and new design applications.

Q: Are there differences in contact material between these parts?

A: Yes. The LAB350-12-2 uses aluminum contacts with tin plating. The LCCF350-12-6 uses copper contacts with electro-tin plating. Copper provides higher electrical conductivity and enhanced corrosion resistance, representing a material improvement in the substitute design.

Q: Do both parts meet the same regulatory requirements?

A: Both parts maintain REACH Unaffected status and identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications. The LCCF350-12-6 carries ROHS3 compliance certification. Regulatory alignment is confirmed for trade and export purposes.

Q: What are the dimensional differences between these connectors?

A: The LAB350-12-2 has a tab thickness of 0.380" (9.65mm) and overall length of 6.610" (167.89mm). The LCCF350-12-6 has a tab thickness of 0.220" (5.59mm) and overall length of 6.360" (161.54mm). Barrel diameters also differ: LAB350-12-2 has a barrel ID of 0.720" (18.29mm) and OD of 1.110" (28.19mm), while LCCF350-12-6 has a barrel ID of 0.840" (21.34mm) and OD of 1.220" (30.99mm).

Q: What is the packaging difference?

A: The LAB350-12-2 packaging specification is not provided. The LCCF350-12-6 is supplied in bulk packaging format.

Q: Are both parts suitable for the same wire gauge applications?

A: Yes. Both the LAB350-12-2 and LCCF350-12-6 are rated for 350MCM (kcmil) wire gauge and feature identical stud size and termination method (crimp, barrel), confirming electrical interface compatibility.
