LAB350-12-2R Equivalent & Substitute Parts

Part Overview

The LAB350-12-2R is an aluminum compression lug manufactured by Panduit Corp, designed for high-amperage electrical terminations. This terminal connector features a rectangular lug configuration with two stud holes, rated for 350MCM (kcmil) wire gauge with a 1/2 inch stud connection. The part is classified as a grounding terminal with non-insulated construction and tin contact finish on aluminum base material.

The LAB350-12-2R is currently discontinued at DiGi Electronics. Identification of equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for replacement and new installations where this specification is required.

Substitute Part Grouping Explanation

Substitution of the LAB350-12-2R is based on electrical and mechanical parameter equivalence within the Panduit LAB series. The critical parameters that determine substitutability are:

Electrical Parameters: Wire gauge rating (350MCM kcmil), stud size (1/2 inch), barrel dimensions (ID 0.720", OD 1.110"), and ring ID (0.530") must remain constant to ensure proper crimping and electrical connection integrity.

Mechanical Parameters: Overall length (6.560"), outer width (1.520"), tab thickness (0.380"), and two-stud-hole configuration must be maintained for mechanical fit and mounting compatibility.

Material and Finish: Aluminum contact material with tin finish and non-insulated construction must be preserved for corrosion resistance and electrical performance.

Compliance: Both parts must maintain ROHS3 compliance and equivalent regulatory status (REACH Unaffected, EAR99 classification).

The substitute part LAB350-12-XR meets all these criteria while offering active product status and improved inventory availability.
