LCC1/0-12DF-X Equivalent & Substitute Parts

Part Overview

The LCC1/0-12DF-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 1/0 AWG wire applications with a 1/2 stud connection. This component is classified as a Pan-Lug™ series terminal and features crimp barrel termination with electro-tin contact finish on copper material. The part is currently listed as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring this terminal specification.

Substitute Part Grouping Explanation

Substitution of the LCC1/0-12DF-X is determined by strict equivalence across critical electrical and mechanical parameters. The substitute part LCC1/0-12-X maintains identical specifications for wire gauge (1/0 AWG), stud size (1/2), terminal type (rectangular tongue), termination method (crimp barrel), tab thickness (0.120"), barrel dimensions (ID 0.390", OD 0.520"), ring ID (0.530"), contact material (copper), contact finish (electro-tin), and insulation type (non-insulated). Both parts share the same base product number (LCC1) and series designation (Pan-Lug™), confirming functional equivalence. The primary distinction is product status: LCC1/0-12DF-X is obsolete while LCC1/0-12-X is active, and packaging differs (DF designation versus bulk packaging). These differences do not affect electrical or mechanical compatibility.

Engineering Selection Recommendations

The LCC1/0-12-X serves as the direct functional equivalent to the obsolete LCC1/0-12DF-X. Selection of LCC1/0-12-X is supported by three primary factors: (1) Active product status ensures ongoing manufacturer support and availability, (2) Complete parameter equivalence across all electrical and mechanical specifications guarantees interchangeability in existing circuit designs and assemblies, and (3) Identical compliance certifications (ROHS3 Compliant, REACH Unaffected) maintain regulatory conformance. The packaging difference between the obsolete DF variant and bulk packaging does not affect terminal performance or compatibility. For applications currently specified with LCC1/0-12DF-X, transition to LCC1/0-12-X presents no technical barriers and provides supply chain continuity.

Frequently Asked Questions (FAQ)

Question	Answer
Can LCC1/0-12-X replace LCC1/0-12DF-X in existing assemblies?	Yes. Both parts are electrically and mechanically identical across all specified parameters including wire gauge, stud size, barrel dimensions, contact material, and termination method. The substitute part maintains full compatibility with existing circuit designs and mounting configurations.
What is the significance of the DF designation in the obsolete part number?	The DF designation indicates a specific packaging variant of the LCC1/0-12 terminal. The active substitute LCC1/0-12-X uses bulk packaging instead. This packaging difference does not affect the terminal's electrical or mechanical performance.
Are there any compliance differences between the two parts?	No. Both LCC1/0-12DF-X and LCC1/0-12-X carry identical compliance certifications: ROHS3 Compliant and REACH Unaffected status. Regulatory requirements are fully maintained with the substitute part.
What parameters determine substitution eligibility for this terminal type?	Substitution eligibility is determined by equivalence in wire gauge (1/0 AWG), stud size (1/2), terminal type (rectangular tongue), termination method (crimp barrel), tab thickness (0.120"), barrel ID/OD dimensions, ring ID dimension, contact material (copper), contact finish (electro-tin), and insulation type (non-insulated). All these parameters are identical between the main part and substitute.
Why is the obsolete part being replaced?	LCC1/0-12DF-X is listed as obsolete, indicating discontinued manufacturing. LCC1/0-12-X is the active equivalent that provides continued availability and manufacturer support while maintaining complete functional equivalence.
Are there inventory considerations when switching to the substitute part?	The substitute part LCC1/0-12-X has 888 pieces in stock compared to 737 pieces of the obsolete LCC1/0-12DF-X. The active part offers superior inventory availability for ongoing procurement needs.
