LCA3/0-12H-X Equivalent & Substitute Parts

Part Overview

The LCA3/0-12H-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 3/0 AWG wire gauge applications with a 1/2 stud connection. This component features crimp barrel termination, electro-tin contact finish, and copper contact material. The part is classified as obsolete, necessitating identification of active equivalent alternatives for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCA3/0-12H-X is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Wire Gauge: 3/0 AWG
• Stud/Tab Size: 1/2 Stud
• Termination Method: Crimp, Barrel
• Contact Material: Copper
• Contact Finish: Electro-Tin
• Barrel ID: 0.510" (12.95mm)
• Barrel OD: 0.640" (16.26mm)
• Ring ID: 0.530" (13.46mm)
• Tab Thickness: 0.130" (3.30mm)
• Width - Outer Edges: 0.960" (24.38mm)
• Insulation: Non-Insulated
• Series: Pan-Lug™
• RoHS Status: ROHS3 Compliant

Variable Parameters Permitting Substitution:

• Terminal Type (Rectangular Tongue vs. Lug, Grounding)
• Overall Length
• Mounting Type (45° Angle vs. Free Hanging In-Line)
• Product Status (Obsolete vs. Active)

The identified substitute parts maintain electrical and mechanical compatibility through identical barrel dimensions, wire gauge capacity, and contact specifications while differing in terminal configuration and mounting orientation.

Engineering Selection Recommendations

LCA3/0-12-X Selection Criteria:

The LCA3/0-12-X is an active product offering identical electrical and mechanical specifications to the obsolete LCA3/0-12H-X with the exception of terminal type and mounting orientation. This substitute maintains full compatibility with 3/0 AWG wire applications and 1/2 stud connections. The lug, grounding terminal type provides equivalent current-carrying capacity through identical barrel dimensions and contact materials. Selection of this part is appropriate for applications where the terminal type change from rectangular tongue to lug configuration is functionally acceptable and where the elimination of 45° angle mounting does not create mechanical constraints.

LCB3/0-12-X Selection Criteria:

The LCB3/0-12-X is an active product maintaining the rectangular tongue terminal type of the obsolete LCA3/0-12H-X while providing increased overall length (3.120" versus unspecified original length). This substitute preserves terminal geometry and mounting style compatibility. Selection of this part is appropriate for applications requiring rectangular tongue terminal configuration where the extended length accommodates system layout requirements.

Both substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical regulatory classifications (EAR99, HTSUS 8536.90.4000) as the original component.

Frequently Asked Questions (FAQ)

Q: Can LCA3/0-12-X be used as a direct replacement for LCA3/0-12H-X?

A: The LCA3/0-12-X shares all critical electrical and mechanical parameters including wire gauge, stud size, barrel dimensions, and contact specifications. The primary difference is terminal type (lug, grounding versus rectangular tongue) and mounting orientation (free hanging in-line versus 45° angle). Substitution is valid where terminal type change is functionally acceptable.

Q: What is the functional difference between the rectangular tongue and lug, grounding terminal types?

A: Both terminal types accommodate identical wire gauges and stud sizes with equivalent current-carrying capacity through matching barrel dimensions. The rectangular tongue provides a different contact geometry compared to the lug configuration. Selection depends on application-specific connection requirements and mechanical layout constraints.

Q: Are there any compliance or regulatory differences between the substitute parts and the original?

A: All three parts maintain identical RoHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and HTSUS code 8536.90.4000. No regulatory or compliance barriers exist to substitution.

Q: How do the overall lengths of the substitute parts compare?

A: The LCA3/0-12-X provides an overall length of 2.580" (65.53mm), while the LCB3/0-12-X provides 3.120" (79.25mm). The original LCA3/0-12H-X overall length is not specified. Length selection depends on available mounting space and system layout requirements.

Q: Do the substitute parts maintain the same wire gauge capacity?

A: Both substitute parts are rated for 3/0 AWG wire gauge with identical barrel inner diameter (0.510"), barrel outer diameter (0.640"), and ring inner diameter (0.530") specifications, ensuring equivalent wire termination capacity.

Q: What is the significance of the 45° angle mounting on the original part?

A: The LCA3/0-12H-X features 45° angle mounting, while both substitute parts feature free hanging in-line mounting. This difference affects physical orientation during installation. Selection of a substitute requires confirmation that the mounting orientation change is compatible with system design.

Q: Are all three parts available in the same packaging format?

A: All three parts are supplied in bulk packaging format, consistent with industrial terminal connector distribution standards.
