3M 30028 Terminal Connector Rectangular - Equivalent & Substitute Parts

Part Overview

The 3M 30028 is a rectangular terminal connector designed for 1 AWG wire gauge applications with a 3/8 stud configuration. This component is classified as obsolete, necessitating identification of active equivalent parts for continued system support and procurement. The terminal features crimp barrel termination, electro-tin contact finish, and non-insulated construction suitable for standard electrical connectivity applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 30028 is determined by strict alignment of electrical and mechanical parameters. The primary substitute, Panduit Corp LCA1-38-E, qualifies based on the following critical parameters:

Wire gauge compatibility (1 AWG), stud size equivalence (3/8 stud), single stud hole terminal style, crimp barrel termination method, free hanging in-line mounting configuration, copper contact material with electro-tin finish, and non-insulated construction. Barrel diameter tolerances (ID: 0.360" vs. 0.358"; OD: 0.470" vs. 0.462") remain within acceptable mechanical substitution ranges for this connector category. Overall length and width dimensions show negligible variation (length: 1.990" vs. 1.970"; width: 0.700" vs. 0.689"), confirming dimensional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Panduit Corp LCA1-38-E terminal connector serves as the direct substitute for the obsolete 3M 30028. Selection of the LCA1-38-E is supported by active product status, ensuring ongoing availability and supply chain continuity. Both components maintain RoHS compliance certifications (RoHS vs. ROHS3), satisfying regulatory requirements for electronic component procurement. The substitute part demonstrates equivalent electrical and mechanical specifications across all critical parameters, with dimensional variations remaining within acceptable tolerances for terminal connector applications. REACH unaffected status is maintained in both components, confirming compliance with chemical substance regulations.

Frequently Asked Questions (FAQ)

Q: What determines if the Panduit LCA1-38-E can replace the 3M 30028?

A: Substitution is based on matching wire gauge (1 AWG), stud size (3/8), terminal style (single stud hole), termination method (crimp barrel), mounting configuration (free hanging in-line), contact material (copper), contact finish (electro-tin), and insulation type (non-insulated). Barrel diameter and overall dimensions must fall within compatible mechanical tolerances.

Q: Are there packaging differences between these parts?

A: The 3M 30028 is supplied in standard packaging, while the Panduit LCA1-38-E is available in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection depends on procurement quantity requirements.

Q: Does the terminal type difference (Standard vs. Lug, Grounding) affect substitution?

A: Both terminal types accommodate the same stud configuration and wire gauge. The functional difference relates to application context; however, the mechanical and electrical substitution criteria remain satisfied for standard connectivity applications.

Q: Are compliance certifications equivalent between the two parts?

A: Both components are RoHS compliant and REACH unaffected. The 3M 30028 carries RoHS certification, while the Panduit LCA1-38-E carries ROHS3 certification, representing an updated compliance standard. Both satisfy current regulatory requirements.

Q: What is the significance of the barrel diameter tolerance differences?

A: Barrel ID and OD variations (0.002" to 0.008") are within standard mechanical tolerances for terminal connectors and do not compromise functional compatibility or electrical performance in this application category.
