Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCD350-12E-X is determined by strict equivalence across the following critical parameters:

Wire Gauge Compatibility: The substitute part must accommodate 350MCM (kcmil) wire gauge to ensure proper current-carrying capacity and mechanical fit within the barrel crimp area.

Stud Configuration: The 1/2 stud size must be maintained to ensure compatibility with existing mounting hardware and electrical connections in the target application.

Terminal Geometry: The rectangular tongue terminal type with two stud holes defines the mechanical interface. Barrel dimensions (ID: 0.700", OD: 0.880") and ring ID (0.530") must remain constant to ensure proper wire insertion and stud engagement.

Termination Method: Crimp barrel termination is the specified joining method and cannot be altered in substitute components.

Material and Finish Specifications: Copper contact material with electro-tin finish ensures electrical conductivity and corrosion resistance consistent with the original design.

Regulatory Compliance: ROHS3 compliance and REACH unaffected status must be maintained in substitute parts.

The LCD350-12-X meets all these criteria and is identified as the active equivalent substitute for the obsolete LCD350-12E-X.

Parameter Comparison

Engineering Selection Recommendations

The LCD350-12-X is the direct active equivalent for the obsolete LCD350-12E-X. Both components share identical electrical and mechanical specifications across all critical parameters including wire gauge, stud configuration, barrel dimensions, and contact materials.

The primary distinction between these parts is product status: LCD350-12E-X is obsolete while LCD350-12-X is active. The LCD350-12-X is manufactured by the same supplier (Panduit Corp) within the same Pan-Lug™ series and maintains full ROHS3 compliance and REACH unaffected status.

A dimensional variation exists in overall length: LCD350-12E-X measures 4.330" (109.98mm) while LCD350-12-X measures 4.960" (125.98mm). This 0.630" (16.00mm) increase in length does not affect the functional electrical or mechanical interface parameters that determine substitution eligibility. The stud hole spacing, barrel dimensions, and ring ID remain constant, ensuring proper installation in existing mounting configurations.

For new designs and replacement applications, the LCD350-12-X is the specified component selection due to its active product status and continued manufacturing availability.

Frequently Asked Questions (FAQ)

Q: Can LCD350-12-X be used as a direct replacement for LCD350-12E-X?

A: Yes. The LCD350-12-X is the active equivalent substitute. Both components share identical wire gauge (350MCM), stud size (1/2), terminal geometry, barrel dimensions, and contact specifications. The substitute is manufactured by Panduit Corp within the same Pan-Lug™ series.

Q: What is the significance of the length difference between these parts?

A: The LCD350-12-X has an overall length of 4.960" compared to 4.330" for the LCD350-12E-X. This 0.630" dimensional increase does not affect the critical electrical or mechanical interface parameters. The stud hole configuration, barrel ID/OD, and ring ID remain identical, maintaining compatibility with existing mounting hardware and electrical connections.

Q: Are there packaging differences between LCD350-12E-X and LCD350-12-X?

A: Yes. The LCD350-12E-X is supplied in standard packaging, while the LCD350-12-X is supplied in bulk packaging. Both are available in new original condition with current inventory levels of 716 pcs and 876 pcs respectively.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both LCD350-12E-X and LCD350-12-X are ROHS3 compliant and REACH unaffected. They maintain identical compliance status and are suitable for applications requiring these certifications.

Q: Why is LCD350-12E-X listed as obsolete?

A: The LCD350-12E-X has been superseded by the LCD350-12-X within Panduit's product line. The active equivalent LCD350-12-X provides the same electrical and mechanical functionality with continued manufacturing support and availability.

Q: Are the crimp barrel specifications identical between these parts?

A: Yes. Both components feature identical barrel dimensions: ID 0.700" (17.78mm) and OD 0.880" (22.35mm). The crimp barrel termination method and wire gauge accommodation (350MCM) are equivalent, ensuring compatible tooling and installation procedures.

Q: Can these parts be intermixed in existing installations?

A: Yes. The LCD350-12-X can be installed in applications currently using LCD350-12E-X. The identical stud size (1/2), ring ID (0.530"), and mounting type (free hanging in-line) ensure mechanical and electrical compatibility. The increased overall length does not interfere with standard installation configurations.
