LCAS1-12-E Equivalent & Substitute Parts

Part Overview

The LCAS1-12-E is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 1 AWG wire gauge applications with a 1/2 stud configuration. This component is classified as obsolete, indicating discontinuation from active production. The terminal features a non-insulated design with electro-tin contact finish and copper contact material, suitable for crimp barrel termination in free-hanging inline mounting applications.

Identification of equivalent and substitute parts is necessary due to the obsolete status of the LCAS1-12-E. Active production alternatives with compatible electrical and mechanical parameters ensure continued availability for maintenance, repair, and new assembly requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the LCAS1-12-E is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Wire gauge (1 AWG), termination method (crimp barrel), contact material (copper), and contact finish (electro-tin) must remain identical to ensure proper electrical conductivity and connection reliability.

Mechanical Parameters: Stud/tab size (1/2 stud), terminal type (rectangular tongue), tab thickness (0.090"), barrel inner diameter (0.360"), barrel outer diameter (0.470"), and ring inner diameter (0.530") must match precisely to ensure mechanical fit and assembly compatibility.

Material & Environmental Parameters: Non-insulated design, copper contact material, and electro-tin finish must be maintained. RoHS3 compliance and EAR99 classification must be preserved.

The substitute part LCA1-12-E meets all these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The LCA1-12-E serves as the direct active production equivalent to the obsolete LCAS1-12-E. Both components are manufactured by Panduit Corp within the Pan-Lug™ series and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The LCAS1-12-E is classified as obsolete, while the LCA1-12-E maintains active product status. This distinction ensures long-term availability and continued manufacturer support for the LCA1-12-E.

Compliance & Certification: Both parts maintain ROHS3 compliance and EAR99 classification, ensuring regulatory equivalence for applications requiring these certifications.

Dimensional Variance: The overall length differs between the two parts (1.940" versus 2.230"), representing a 0.290" increase in the substitute. This dimensional change does not affect electrical performance or mechanical fit at the connection interface, as all critical barrel and ring dimensions remain identical. Assembly space requirements should be evaluated for applications with spatial constraints.

Packaging Consideration: The LCA1-12-E is supplied in bulk packaging, whereas the LCAS1-12-E packaging specification is not provided. Bulk packaging may require adjustment to existing procurement and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can the LCA1-12-E replace the LCAS1-12-E in existing assemblies?

A: Yes. The LCA1-12-E is electrically and mechanically equivalent to the LCAS1-12-E across all critical parameters including wire gauge, stud size, barrel dimensions, and contact specifications. The primary difference is the overall length (2.230" versus 1.940"), which does not affect connection interface compatibility.

Q: What is the significance of the overall length difference between these parts?

A: The LCA1-12-E is 0.290" longer than the LCAS1-12-E. This difference affects only the free-hanging portion of the terminal and does not impact electrical performance or mechanical fit at the stud connection point. Applications with spatial constraints should account for this dimensional change.

Q: Why is the LCAS1-12-E classified as obsolete?

A: Obsolete status indicates the part has been discontinued from active production by the manufacturer. The LCA1-12-E represents the active production alternative within the same product family.

Q: Are there any compliance differences between these parts?

A: No. Both the LCAS1-12-E and LCA1-12-E maintain identical RoHS3 compliance status and EAR99 export classification.

Q: What is the difference in packaging between these parts?

A: The LCA1-12-E is supplied in bulk packaging, while the LCAS1-12-E packaging specification is not documented. Bulk packaging may require different handling and storage procedures compared to alternative packaging formats.

Q: Are the barrel and ring dimensions identical between these parts?

A: Yes. All critical dimensions including barrel inner diameter (0.360"), barrel outer diameter (0.470"), ring inner diameter (0.530"), and tab thickness (0.090") are identical, ensuring mechanical compatibility at the connection interface.

Q: Can the LCA1-12-E be used in new designs as well as replacements?

A: Yes. The LCA1-12-E is the active production part and is suitable for both new design implementations and replacement of obsolete LCAS1-12-E components.
