LCAF6-56-L Equivalent & Substitute Parts
Part Overview
The LCAF6-56-L is a rectangular tongue terminal connector manufactured by Panduit Corp, designed for 6 AWG wire termination with a 5/16 stud connection. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system maintenance. The terminal features non-insulated copper construction with electro-tin contact finish, suitable for free-hanging in-line mounting applications requiring crimp barrel termination.

Substitute Part Grouping Explanation
Substitution eligibility for the LCAF6-56-L is determined by the following critical parameters:
Fixed Compatibility Parameters:
- Manufacturer: Panduit Corp (Pan-Lug™ series)
- Terminal Type: Rectangular Tongue
- Stud/Tab Size: 5/16 Stud (Ring ID: 0.340")
- Termination Method: Crimp, Barrel
- Contact Material: Copper
- Contact Finish: Electro-Tin
- Insulation: Non-Insulated
- Mounting Type: Free Hanging (In-Line)
Variable Parameters Defining Wire Gauge Substitution:
- Wire Gauge: Determines barrel dimensions and tab thickness
- Barrel ID/OD: Scales with wire gauge
- Overall Length: Adjusts based on wire gauge
- Tab Thickness: Increases with wire gauge
The LCAX4-56-L qualifies as a substitute based on matching all fixed compatibility parameters while accommodating a different wire gauge (4 AWG versus 6 AWG). This substitution is valid only when the application circuit design permits wire gauge modification.

Engineering Selection Recommendations
The LCAF6-56-L is classified as obsolete, requiring transition to active equivalent components. The LCAX4-56-L is the identified substitute within the Pan-Lug™ series, maintaining identical stud connection geometry (5/16 stud with 0.340" ring ID) and electrical interface specifications.
Selection Basis:
The LCAX4-56-L is active and maintains ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the original component. Both parts employ identical contact material (copper), contact finish (electro-tin), and termination methodology (crimp barrel).
Critical Consideration:
The wire gauge difference (4 AWG versus 6 AWG) represents a material change in application scope. The 4 AWG substitute accommodates larger conductor cross-sections. Selection of the LCAX4-56-L requires verification that the circuit design permits this wire gauge modification and that the associated barrel dimensions (0.280" ID for 4 AWG versus 0.220" ID for 6 AWG) are compatible with available crimping equipment and connector pin specifications.
Frequently Asked Questions (FAQ)
Q: Can the LCAX4-56-L directly replace the LCAF6-56-L in all applications?
A: The LCAX4-56-L shares identical stud connection geometry and electrical interface specifications. However, the wire gauge difference (4 AWG versus 6 AWG) requires circuit design compatibility verification. The larger barrel dimensions of the 4 AWG terminal necessitate confirmation that crimping equipment and mating connector pins accommodate the increased conductor size.
Q: What determines substitution eligibility between these terminals?
A: Substitution is governed by fixed parameters: manufacturer (Panduit Corp), terminal type (rectangular tongue), stud size (5/16), contact material (copper), contact finish (electro-tin), and termination method (crimp barrel). Wire gauge is a variable parameter that scales barrel dimensions proportionally. Substitution is valid when the application circuit permits wire gauge modification.
Q: Are there compliance differences between the main part and substitute?
A: Both the LCAF6-56-L and LCAX4-56-L maintain ROHS3 compliance and REACH unaffected status. No regulatory compliance barriers exist for substitution. The primary distinction is product status: the main part is obsolete while the substitute is active.
Q: What is the significance of the ring ID dimension?
A: The ring ID (0.340" for both parts) defines the stud connection interface. This dimension must match the mating stud diameter to ensure proper mechanical and electrical connection. Identical ring ID values confirm that both terminals interface with the same stud size (5/16).
Q: How do barrel dimensions affect terminal selection?
A: Barrel dimensions (ID and OD) scale with wire gauge to accommodate conductor cross-section. The 6 AWG terminal features a 0.220" barrel ID, while the 4 AWG substitute features a 0.280" barrel ID. Crimping equipment must be calibrated for the specific wire gauge and barrel dimensions. Mismatched equipment and terminal specifications result in improper termination.
Q: What is the impact of tab thickness differences?
A: Tab thickness increases from 0.070" (6 AWG) to 0.090" (4 AWG) to accommodate larger conductor cross-sections and distribute crimping force appropriately. This dimension is integral to the terminal design and scales with wire gauge. No field adjustment is possible.
Q: Are there packaging considerations for procurement?
A: The LCAF6-56-L is listed as obsolete with 961 pieces in stock. The LCAX4-56-L is active with 1260 pieces available in bulk packaging. Procurement planning should account for the active status and bulk availability of the substitute component.
