LCAS2-12-Q Equivalent & Substitute Parts

Part Overview

The LCAS2-12-Q is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 2 AWG wire gauge applications with a 1/2 stud connection. This component is classified as a Pan-Lug™ series terminal and features crimp barrel termination for secure wire attachment. The part is currently listed with Obsolete product status, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this terminal specification.

Substitute Part Grouping Explanation

Substitution eligibility for the LCAS2-12-Q is determined by strict equivalence across the following critical parameters: wire gauge (2 AWG), stud size (1/2), terminal type (rectangular tongue), termination method (crimp barrel), barrel dimensions (ID 0.310", OD 0.420"), ring ID (0.530"), tab thickness (0.080"), contact material (copper), contact finish (electro-tin), and insulation classification (non-insulated). The LCA2-12-Q meets all these criteria and is identified as a direct substitute. Both parts maintain identical electrical and mechanical specifications for the connection interface, differing only in overall length dimension, which does not affect functional compatibility in standard mounting applications.

Engineering Selection Recommendations

The LCA2-12-Q is the direct substitute for the obsolete LCAS2-12-Q. Both components are manufactured by Panduit Corp within the Pan-Lug™ series and maintain identical specifications across all critical electrical and mechanical parameters governing terminal connector functionality. The substitute part carries Active product status, ensuring ongoing availability and supply chain reliability. Both parts maintain ROHS3 compliance and identical export classification (EAR99), supporting regulatory consistency in applications. The LCA2-12-Q provides equivalent performance for 2 AWG wire termination to 1/2 stud connections with identical barrel and ring dimensions. The variance in overall length (2.210" versus 1.890") does not affect electrical performance or mechanical compatibility in standard mounting configurations and may provide additional material in the terminal body.

Frequently Asked Questions (FAQ)

Q: Can the LCA2-12-Q be used as a direct replacement for the LCAS2-12-Q in existing applications?

A: Yes. The LCA2-12-Q is a direct substitute meeting all critical specifications: identical wire gauge (2 AWG), stud size (1/2), barrel dimensions (ID 0.310", OD 0.420"), ring ID (0.530"), tab thickness (0.080"), contact material (copper), contact finish (electro-tin), and termination method (crimp barrel). The difference in overall length does not affect functional compatibility.

Q: What is the primary reason for substitution?

A: The LCAS2-12-Q is classified as Obsolete. The LCA2-12-Q is an Active product from the same manufacturer and series, providing continued availability for applications requiring this terminal specification.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain identical RoHS3 compliance status, ECCN classification (EAR99), and HTSUS code (8536.90.4000).

Q: Does the longer overall length of the LCA2-12-Q affect installation?

A: The LCA2-12-Q has an overall length of 2.210" compared to 1.890" for the LCAS2-12-Q. This dimensional difference does not affect the electrical connection interface or mechanical compatibility with standard 1/2 stud mounting applications. Space constraints in specific installations should be evaluated independently.

Q: Are both parts non-insulated?

A: Yes. Both the LCAS2-12-Q and LCA2-12-Q are non-insulated terminals with identical copper contact material and electro-tin finish.

Q: What is the wire gauge capacity for these terminals?

A: Both terminals are rated for 2 AWG wire gauge with identical barrel dimensions (ID 0.310", OD 0.420") for secure crimp termination.
