LCAF1-12F-X Equivalent & Substitute Parts

Part Overview

The LCAF1-12F-X is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 1 AWG wire gauge applications with a 1/2 stud connection. This Pan-Lug™ series terminal features a non-insulated copper construction with electro-tin contact finish, suitable for crimp barrel termination in free-hanging and right-angle mounting configurations.

The LCAF1-12F-X carries an obsolete product status. Equivalent and substitute parts are available to maintain continuity in applications requiring rectangular tongue terminals with matching electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the LCAF1-12F-X are determined by compatibility across the following critical parameters:

Primary Compatibility Criteria:

Wire gauge rating (1 AWG)
Stud/tab size (1/2 stud)
Terminal type (rectangular tongue)
Termination method (crimp, barrel)
Contact material and finish (copper, electro-tin)
Mounting configuration (free hanging, right angle)

Substitution Logic:

The LCAF1-12-X serves as a direct equivalent substitute. This part maintains identical wire gauge, stud size, terminal type, and termination specifications. The primary distinction is product status: LCAF1-12-X is active, whereas LCAF1-12F-X is obsolete. Both parts share the same base product number (LCAF) and series designation (Pan-Lug™).

The LCAX1/0-12F-X represents a related substitute for applications requiring increased wire gauge capacity. This part accommodates 1/0 AWG wire, representing the next gauge size above 1 AWG. While the stud size remains 1/2, the barrel and tab dimensions increase proportionally to accommodate the larger wire cross-section. This part is suitable only when the application permits upgrade to 1/0 AWG wire gauge.

Engineering Selection Recommendations

LCAF1-12-X Selection:

The LCAF1-12-X is the primary substitute for the obsolete LCAF1-12F-X. This part provides identical electrical and mechanical compatibility for 1 AWG applications. The LCAF1-12-X maintains active product status with current manufacturing support and availability. Both parts are ROHS3 compliant and carry identical regulatory classifications. Selection of LCAF1-12-X eliminates obsolescence risk while preserving all functional specifications.

LCAX1/0-12F-X Selection:

The LCAX1/0-12F-X is applicable only when the application design permits wire gauge upgrade from 1 AWG to 1/0 AWG. This part accommodates larger conductor cross-sections while maintaining the 1/2 stud connection point. The increased barrel diameter (0.450" ID versus 0.390" ID) and tab thickness (0.130" versus 0.120") reflect the larger wire gauge requirement. This substitute is suitable for applications where current-carrying capacity must increase or where 1/0 AWG wire is specified. The LCAX1/0-12F-X is active and ROHS3 compliant.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. No regulatory or compliance barriers exist for substitution.

Frequently Asked Questions (FAQ)

Q: Can LCAF1-12-X directly replace LCAF1-12F-X in existing applications?

A: Yes. The LCAF1-12-X provides direct substitution for the obsolete LCAF1-12F-X. Both parts share identical wire gauge (1 AWG), stud size (1/2), terminal type (rectangular tongue), and termination method (crimp, barrel). Mechanical and electrical compatibility is complete.

Q: What is the primary difference between LCAF1-12F-X and LCAF1-12-X?

A: The primary difference is product status. LCAF1-12F-X is obsolete, while LCAF1-12-X is active. The "F" designation in LCAF1-12F-X indicates right-angle mounting capability, whereas LCAF1-12-X specifies free-hanging in-line mounting. Both parts are functionally equivalent for 1 AWG applications with 1/2 stud connections.

Q: When should LCAX1/0-12F-X be used instead of LCAF1-12-X?

A: LCAX1/0-12F-X is selected when the application requires 1/0 AWG wire gauge capacity. This part accommodates larger conductor cross-sections than 1 AWG. The stud size remains 1/2, but barrel and tab dimensions increase proportionally. Use LCAX1/0-12F-X only when the application design specifies or permits 1/0 AWG wire.

Q: Are all substitute parts RoHS compliant?

A: Yes. LCAF1-12-X and LCAX1/0-12F-X are both ROHS3 compliant, matching the compliance status of LCAF1-12F-X.

Q: What is the difference in mounting configuration between the main part and substitutes?

A: LCAF1-12F-X supports both free-hanging in-line and right-angle mounting. LCAF1-12-X supports free-hanging in-line mounting only. LCAX1/0-12F-X supports both free-hanging in-line and right-angle mounting. Verify mounting requirements before selection.

Q: Do the substitute parts have the same barrel dimensions?

A: LCAF1-12-X maintains identical barrel dimensions to LCAF1-12F-X (0.390" ID, 0.590" OD). LCAX1/0-12F-X has larger barrel dimensions (0.450" ID, 0.580" OD) to accommodate 1/0 AWG wire. Barrel dimension compatibility is critical for proper crimp termination.

Q: Are inventory levels sufficient for both substitute parts?

A: LCAF1-12-X has 1113 pieces in stock. LCAX1/0-12F-X has 1004 pieces in stock. Both substitutes maintain active inventory status.
