Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Stud/Tab Size: 5/16 Stud
• Terminal Type: Rectangular Tongue
• Contact Material: Copper
• Contact Finish: Electro-Tin
• Termination Method: Crimp, Barrel
• 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 LCB4-56F-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.

Series Continuity: Both the main part and substitute parts belong to the Pan-Lug™ series, ensuring design and form factor consistency.

Parameter Comparison

Engineering Selection Recommendations

The LCB4-56-L serves as the direct active equivalent for the obsolete LCB4-56F-L. Selection of this substitute is based on the following engineering criteria:

Product Status Transition: The LCB4-56F-L is classified as obsolete, while the LCB4-56-L maintains active product status with current manufacturing and distribution support. This transition ensures long-term component availability and supply chain continuity.

Electrical and Mechanical Equivalence: All critical electrical and mechanical parameters are identical between the main part and substitute, including stud size, barrel dimensions, contact material, contact finish, and termination method. These parameters directly determine functional compatibility within the application circuit.

Wire Gauge Consideration: The LCB4-56-L is rated for 4 AWG wire gauge, which represents a subset of the LCB4-56F-L's 2-4 AWG range. For applications utilizing 4 AWG conductors, the substitute provides full functional equivalence. Applications requiring 2 or 3 AWG wire gauges require evaluation of alternative parts within the Pan-Lug™ series.

Compliance Enhancement: The LCB4-56-L carries ROHS3 compliance certification, providing enhanced regulatory alignment compared to the obsolete predecessor. REACH status remains unaffected for both parts.

Packaging and Inventory: The substitute part is available in bulk packaging with 944 pieces in current stock, supporting production requirements and reducing lead time risk.

Frequently Asked Questions (FAQ)

Q: Can the LCB4-56-L directly replace the LCB4-56F-L in existing designs?

A: The LCB4-56-L provides direct functional replacement for applications utilizing 4 AWG wire gauge. All electrical and mechanical parameters are equivalent, including stud size, barrel dimensions, contact material, and termination method. For applications requiring 2 or 3 AWG wire gauges, alternative parts must be evaluated.

Q: What is the primary difference between these two parts?

A: The LCB4-56F-L is obsolete with a wire gauge range of 2-4 AWG, while the LCB4-56-L is an active product rated for 4 AWG only. The LCB4-56-L also includes ROHS3 compliance certification. All other specifications are identical.

Q: Are the barrel dimensions identical between the two parts?

A: Yes. Both parts feature identical barrel inner diameter (0.280"), outer diameter (0.380"), and ring inner diameter (0.340"). These dimensions ensure mechanical compatibility with mating connectors and studs.

Q: What packaging options are available for the substitute part?

A: The LCB4-56-L is supplied in bulk packaging, distinct from the main part's unspecified packaging format. Bulk packaging is suitable for high-volume production environments.

Q: Does the substitute part meet current regulatory requirements?

A: The LCB4-56-L carries ROHS3 compliance certification, meeting current European Union regulatory requirements for restricted substances. Both parts maintain REACH unaffected status and EAR99 export classification.

Q: Are there wire gauge limitations when using the substitute part?

A: The LCB4-56-L is rated for 4 AWG wire gauge only, compared to the main part's 2-4 AWG range. Applications requiring 2 or 3 AWG conductors must identify alternative parts from the Pan-Lug™ series with appropriate wire gauge ratings.

Q: What is the contact finish specification for both parts?

A: Both the LCB4-56F-L and LCB4-56-L feature electro-tin contact finish applied to copper base material, providing corrosion resistance and reliable electrical contact characteristics.
