LCB4/0-12F-X Equivalent & Substitute Parts

Part Overview

The LCB4/0-12F-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 4/0 AWG wire gauge applications with a 1/2 stud configuration. This component is classified as obsolete, indicating discontinuation from active production. Equivalent and substitute parts are necessary to maintain system compatibility and ensure continued availability for applications requiring this terminal specification.

Substitute Part Grouping Explanation

Substitution eligibility for the LCB4/0-12F-X is determined by strict equivalence across the following critical parameters: wire gauge (4/0 AWG), stud size (1/2), terminal type (rectangular tongue), termination method (crimp barrel), tab thickness (0.140"), barrel dimensions (ID 0.570", OD 0.710"), ring ID (0.530"), contact material (copper), contact finish (electro-tin), and insulation type (non-insulated).

The substitute parts LCA4/0-12F-X and LCB4/0-12-X meet these core electrical and mechanical requirements. Differences in product status, packaging configuration, and mounting type do not affect functional interchangeability within the specified parameter set.

Engineering Selection Recommendations

Both LCA4/0-12F-X and LCB4/0-12-X are active production alternatives to the obsolete LCB4/0-12F-X. All three parts maintain identical electrical and mechanical specifications across wire gauge, stud configuration, barrel dimensions, and contact properties.

LCA4/0-12F-X provides direct functional equivalence with active product status and ROHS3 compliance. LCB4/0-12-X also provides active availability with identical core specifications; the difference in mounting type designation (Free Hanging In-Line versus Free Hanging In-Line, Right Angle) reflects packaging configuration rather than functional incompatibility.

Both substitute parts carry equivalent regulatory compliance: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Selection between substitutes should be based on packaging availability and application-specific mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can LCA4/0-12F-X directly replace LCB4/0-12F-X?

A: Yes. LCA4/0-12F-X meets all electrical and mechanical parameters of the obsolete LCB4/0-12F-X, including wire gauge (4/0 AWG), stud size (1/2), barrel dimensions, contact material, and termination method. LCA4/0-12F-X is active production status.

Q: What is the difference between LCB4/0-12F-X and LCB4/0-12-X?

A: The primary difference is mounting type designation: LCB4/0-12F-X specifies Free Hanging (In-Line), Right Angle, while LCB4/0-12-X specifies Free Hanging (In-Line). All other electrical and mechanical parameters are identical. Both are active production.

Q: Are all three parts ROHS3 compliant?

A: Yes. LCB4/0-12F-X, LCA4/0-12F-X, and LCB4/0-12-X are all ROHS3 Compliant with REACH Unaffected status.

Q: Does packaging type affect substitution eligibility?

A: Packaging type (bulk versus other configurations) does not affect electrical or mechanical interchangeability. All substitute parts function identically within the specified parameter set.

Q: What wire gauge do these terminals accommodate?

A: All three parts are rated for 4/0 AWG wire gauge with crimp barrel termination.

Q: Are these terminals insulated?

A: No. LCB4/0-12F-X, LCA4/0-12F-X, and LCB4/0-12-X are all non-insulated terminals.
