LCAF4/0-56F-X Equivalent & Substitute Parts

Part Overview

The LCAF4/0-56F-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4/0 AWG wire gauge applications with a 5/16 stud connection. This component is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity and support ongoing system requirements. The terminal features non-insulated copper construction with electro-tin contact finish, suitable for crimp barrel termination in free-hanging and right-angle mounting configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCAF4/0-56F-X is determined by strict alignment of the following critical parameters:

Core Compatibility Requirements:

• Wire gauge: 4/0 AWG (fixed requirement)
• Stud/tab size: 5/16 Stud (fixed requirement)
• Terminal type: Rectangular Tongue (fixed requirement)
• Terminal style: Single Stud Hole (fixed requirement)
• Termination method: Crimp, Barrel (fixed requirement)
• Contact material: Copper (fixed requirement)
• Ring ID: 0.340" (8.64mm) (fixed requirement)
• Manufacturer: Panduit Corp (fixed requirement)
• Series: Pan-Lug™ (fixed requirement)

Allowable Variation Parameters:

• Tab thickness: 0.140" to 0.160" (within tolerance range)
• Barrel ID: 0.630" to 0.650" (within tolerance range)
• Barrel OD: 0.810" to 0.910" (within tolerance range)
• Width - Outer Edges: 1.170" to 1.190" (within tolerance range)
• Mounting type: Free Hanging (In-Line) or Right Angle configurations
• Color: Yellow or Purple (functional equivalence)
• Product status: Active alternatives to obsolete part

The identified substitute parts maintain electrical and mechanical compatibility while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

LCAF4/0-56-X Selection Criteria:

The LCAF4/0-56-X represents the closest functional equivalent to the LCAF4/0-56F-X. This part maintains identical electrical and mechanical specifications including tab thickness (0.140"), barrel dimensions (0.630" ID / 0.910" OD), and outer width (1.170"). The primary distinction is product status: LCAF4/0-56-X is active with current manufacturing support, whereas LCAF4/0-56F-X is obsolete. The LCAF4/0-56-X accommodates free-hanging in-line mounting configuration. This part is suitable for direct replacement in applications where right-angle mounting is not required.

LCAX4/0-56F-X Selection Criteria:

The LCAX4/0-56F-X provides an alternative with active product status and supports both free-hanging in-line and right-angle mounting configurations, matching the LCAF4/0-56F-X mounting flexibility. This part exhibits measurable dimensional variations: increased tab thickness (0.160" versus 0.140"), slightly larger outer width (1.190" versus 1.170"), and modified barrel dimensions (0.650" ID / 0.810" OD). These variations remain within acceptable tolerance ranges for 4/0 AWG rectangular tongue terminal applications. The LCAX4/0-56F-X is appropriate for applications requiring right-angle mounting capability or where the dimensional tolerances are compatible with system requirements.

Compliance Status:

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the main part specifications. All three parts are manufactured by Panduit Corp within the Pan-Lug™ series, ensuring design continuity and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can LCAF4/0-56-X directly replace LCAF4/0-56F-X in all applications?

A: The LCAF4/0-56-X provides electrical and mechanical equivalence for applications utilizing free-hanging in-line mounting. The LCAF4/0-56F-X supports both in-line and right-angle configurations. If right-angle mounting is required, the LCAF4/0-56-X is not suitable; use LCAX4/0-56F-X instead.

Q: What are the dimensional differences between LCAX4/0-56F-X and LCAF4/0-56F-X?

A: The LCAX4/0-56F-X exhibits three measurable dimensional variations: tab thickness increases from 0.140" to 0.160", outer width increases from 1.170" to 1.190", and barrel dimensions change from 0.630" ID/0.910" OD to 0.650" ID/0.810" OD. These variations fall within acceptable tolerance ranges for 4/0 AWG terminal applications.

Q: Are color differences between Yellow (LCAF4/0-56-X) and Purple (LCAX4/0-56F-X) functionally significant?

A: Color coding in terminal connectors serves identification purposes only and does not affect electrical or mechanical performance. Both yellow and purple variants maintain identical contact material (copper), contact finish (electro-tin), and termination specifications.

Q: What is the significance of the "F" designation in part numbers LCAF4/0-56F-X and LCAX4/0-56F-X?

A: The "F" designation indicates right-angle mounting capability. LCAF4/0-56-X (without "F") supports free-hanging in-line mounting only. LCAF4/0-56F-X and LCAX4/0-56F-X both support right-angle configurations.

Q: Are all three parts ROHS3 compliant?

A: Yes. LCAF4/0-56F-X, LCAF4/0-56-X, and LCAX4/0-56F-X are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging options are available for substitute parts?

A: LCAF4/0-56-X and LCAX4/0-56F-X are supplied in bulk packaging. Inventory availability is confirmed at 766 pieces and 694 pieces respectively.

Q: Can LCAX4/0-56F-X be used in applications originally designed for LCAF4/0-56F-X?

A: LCAX4/0-56F-X is compatible with applications requiring right-angle mounting and accommodating the specified dimensional tolerances. The increased tab thickness (0.160" versus 0.140") and modified barrel dimensions must be verified against system mechanical constraints before implementation.
