LCD4-12F-L Equivalent & Substitute Parts

Part Overview

The LCD4-12F-L is a copper compression lug terminal manufactured by Panduit Corp, part of the Pan-Lug™ series. This component is a rectangular tongue terminal connector designed for 2-4 AWG wire gauges with a 1/2 inch stud mounting configuration. The terminal features a two-stud hole design and is rated for crimp barrel termination on non-insulated applications.

The LCD4-12F-L is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain circuit continuity and ensure continued availability for repair, maintenance, and new assembly applications where this terminal type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCD4-12F-L is based on strict equivalence of electrical and mechanical parameters. The substitute part LCC4-12W-L maintains compatibility through the following critical parameters:

Electrical Compatibility:

• Wire gauge range: 2-4 AWG (identical)
• Barrel inner diameter: 0.280" (7.11mm) (identical)
• Barrel outer diameter: 0.380" (9.65mm) (identical)
• Ring inner diameter: 0.530" (13.46mm) (identical)
• Contact material: Copper (identical)
• Contact finish: Electro-Tin (identical)
• Termination method: Crimp, Barrel (identical)

Mechanical Compatibility:

• Terminal type: Rectangular Tongue (identical)
• Stud/tab size: 1/2 Stud (identical)
• Terminal style: Two Stud Holes (identical)
• Width - outer edges: 0.750" (19.05mm) (identical)
• Mounting type: Free Hanging (In-Line) (compatible)
• Insulation: Non-Insulated (identical)
• Color: Gray (identical)

The LCC4-12W-L is an active product within the same Pan-Lug™ series, ensuring design continuity and functional equivalence for applications requiring the LCD4-12F-L.

Parameter Comparison

Engineering Selection Recommendations

The LCC4-12W-L is the direct substitute for the obsolete LCD4-12F-L. Both components share identical electrical and mechanical specifications for wire gauge, barrel dimensions, ring diameter, contact material, and termination method. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The LCC4-12W-L carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both parts maintain the same ECCN and HTSUS classifications, confirming equivalence for export and trade purposes.

The primary difference between the two parts is tab thickness: the LCD4-12F-L specifies 0.120" (3.05mm) while the LCC4-12W-L specifies 0.070" (1.78mm). This dimensional variation does not affect electrical performance or functional compatibility in standard 2-4 AWG crimp barrel termination applications. The mounting type designation differs slightly (Right Angle versus In-Line), though both are classified as Free Hanging configurations.

For new designs and replacement applications, the LCC4-12W-L is the appropriate selection due to its active product status and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the LCC4-12W-L directly replace the LCD4-12F-L in existing assemblies?

A: Yes. Both components are electrically and mechanically equivalent for 2-4 AWG wire gauge applications. The barrel inner diameter (0.280"), barrel outer diameter (0.380"), and ring inner diameter (0.530") are identical, ensuring proper wire crimp and stud connection. The contact material, finish, and termination method are identical.

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

A: The LCD4-12F-L has a tab thickness of 0.120" (3.05mm) while the LCC4-12W-L has a tab thickness of 0.070" (1.78mm). This difference does not affect electrical performance or mechanical compatibility in standard applications. Tab thickness is a structural characteristic that does not impact the crimp barrel interface or stud mounting function.

Q: Why is the LCD4-12F-L classified as obsolete?

A: The LCD4-12F-L is no longer in active production. The LCC4-12W-L serves as the current production equivalent within the Pan-Lug™ series, offering the same electrical and mechanical functionality with active availability and regulatory compliance.

Q: Are there packaging differences between these parts?

A: The LCD4-12F-L packaging is not specified in available documentation. The LCC4-12W-L is supplied in bulk packaging. Packaging format does not affect component performance or substitution compatibility.

Q: Do both parts meet current regulatory standards?

A: The LCC4-12W-L is ROHS3 compliant and REACH unaffected. The LCD4-12F-L regulatory status is not specified. Both parts carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: What wire gauges are supported by these terminals?

A: Both the LCD4-12F-L and LCC4-12W-L support 2-4 AWG wire gauges. The barrel dimensions (0.280" ID, 0.380" OD) are sized specifically for this wire gauge range.

Q: Are these terminals suitable for insulated or non-insulated applications?

A: Both components are non-insulated terminals. They are designed for direct copper-to-copper contact applications without insulation sleeves.
