LCB4-56H-L Equivalent & Substitute Parts

Part Overview

The LCB4-56H-L is a copper rectangular tongue terminal connector manufactured by Panduit Corp, designed for wire gauges 2-4 AWG with a 5/16 stud connection. This component is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure procurement availability. The terminal features a 45° angle mounting configuration with crimp barrel termination and electro-tin contact finish on copper base material.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCB4-56H-L is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Panduit Corp
• Series: Pan-Lug™
• Terminal Type: Rectangular Tongue
• Stud/Tab Size: 5/16 Stud
• Termination Method: Crimp, Barrel
• Contact Material: Copper
• Contact Finish: Electro-Tin
• Barrel ID: 0.280" (7.11mm)
• Barrel OD: 0.380" (9.65mm)
• Ring ID: 0.340" (8.64mm)
• Tab Thickness: 0.070" (1.78mm)
• Insulation: Non-Insulated

Wire Gauge Compatibility: The LCB4-56H-L accommodates wire gauges 2-4 AWG. Substitute parts must support the required wire gauge range or a subset thereof that includes the application's specified gauge.

Mounting Configuration: The LCB4-56H-L features a 45° angle mounting. Substitute parts with standard free-hanging in-line mounting (0° configuration) represent a functional variation and are evaluated separately.

Parameter Comparison

Engineering Selection Recommendations

LCB4-56-L as Primary Substitute:

The LCB4-56-L is the direct functional equivalent for applications requiring 4 AWG wire termination. This part maintains electrical and mechanical compatibility across all critical parameters: identical stud size (5/16), barrel dimensions, contact material and finish, and termination method. The LCB4-56-L is currently active in production with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

Wire Gauge Consideration:

The LCB4-56-L is rated for 4 AWG only, whereas the LCB4-56H-L accommodates 2-4 AWG. Applications requiring 2 or 3 AWG termination must source alternative parts from the Pan-Lug™ series with expanded wire gauge ratings.

Mounting Configuration Variation:

The LCB4-56-L features standard free-hanging in-line mounting without the 45° angle configuration of the LCB4-56H-L. Applications with spatial or angular constraints must evaluate whether this mounting variation is compatible with the circuit board layout and connector interface.

Compliance and Procurement:

The LCB4-56-L carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The obsolete status of LCB4-56H-L necessitates transition to the active LCB4-56-L for new designs and ongoing procurement.

Frequently Asked Questions (FAQ)

Q: Can LCB4-56-L directly replace LCB4-56H-L in all applications?

A: The LCB4-56-L is electrically and mechanically compatible for applications using 4 AWG wire. The primary difference is the mounting configuration: LCB4-56-L uses standard free-hanging in-line mounting, while LCB4-56H-L includes a 45° angle. Verify that the mounting variation does not conflict with your circuit board layout or connector interface requirements.

Q: What is the wire gauge limitation of LCB4-56-L?

A: The LCB4-56-L is rated for 4 AWG wire only. The original LCB4-56H-L accommodates 2-4 AWG. If your application requires 2 or 3 AWG termination, the LCB4-56-L is not suitable. Contact the manufacturer for Pan-Lug™ series alternatives with broader wire gauge ratings.

Q: Are the barrel dimensions identical between these parts?

A: Yes. Both parts share identical barrel specifications: 0.280" (7.11mm) inner diameter and 0.380" (9.65mm) outer diameter. Ring ID is also identical at 0.340" (8.64mm). These dimensions ensure mechanical compatibility with mating connectors and stud interfaces.

Q: Does LCB4-56-L meet current compliance standards?

A: Yes. The LCB4-56-L is ROHS3 compliant and REACH unaffected. The LCB4-56H-L product status is obsolete with unspecified compliance. Transition to LCB4-56-L ensures alignment with current regulatory requirements.

Q: What is the packaging difference?

A: The LCB4-56H-L packaging is not specified in available documentation. The LCB4-56-L is supplied in bulk packaging. Confirm packaging requirements with your procurement department for order quantity and handling specifications.

Q: Are both parts from the same manufacturer?

A: Yes. Both LCB4-56H-L and LCB4-56-L are manufactured by Panduit Corp and belong to the Pan-Lug™ series, ensuring design consistency and quality standards.

Q: What is the contact finish material?

A: Both parts feature electro-tin contact finish applied to copper base material. This finish provides corrosion resistance and reliable electrical conductivity for the 5/16 stud connection.
