Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAB400-12-24 is determined by strict equivalence across the following critical parameters:

Wire Gauge Compatibility: 400MCM (kcmil) — substitute parts must support identical wire gauge capacity.

Stud/Tab Size: 1/2 Stud — mechanical interface requirement for mounting and connection.

Terminal Style: Two Stud Holes — physical configuration for fastening and alignment.

Termination Method: Crimp — connection technique must remain consistent.

Contact Material & Finish: Aluminum with Tin finish — electrical and corrosion resistance properties.

Mechanical Dimensions: Barrel ID (0.760"), Barrel OD (1.190"), Ring ID (0.530"), Tab Thickness (0.390"), Overall Length (6.940"), Outer Width (1.610") — all dimensions must match for mechanical fit and electrical performance.

Mounting Type: Free Hanging (In-Line) — installation configuration.

The LAB400-12-24F qualifies as a direct substitute based on full alignment with these parameters. The primary distinction is terminal type classification (Standard vs. Lug, Grounding) and product status (Discontinued vs. Active).

Parameter Comparison

Engineering Selection Recommendations

LAB400-12-24F is the manufacturer-recommended substitute for the discontinued LAB400-12-24. Selection of the LAB400-12-24F is supported by the following engineering criteria:

Product Status: The LAB400-12-24F maintains Active status, ensuring continued manufacturer support, availability, and compliance with current production standards. The original LAB400-12-24 is Discontinued at DiGi Electronics, creating supply chain risk.

Electrical & Mechanical Equivalence: All critical electrical parameters (wire gauge, contact material, contact finish, termination method) and mechanical dimensions (stud size, barrel dimensions, overall length and width) are identical between the two parts.

Functional Compatibility: Both parts are designed for 400MCM wire gauge applications with identical mounting and connection configurations. The LAB400-12-24F classification as a Lug, Grounding terminal does not alter the core electrical or mechanical interface requirements.

Compliance & Certifications: Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, indicating equivalent regulatory and trade compliance status.

For applications currently specified with LAB400-12-24, direct substitution with LAB400-12-24F is supported by full parameter equivalence and manufacturer recommendation.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between LAB400-12-24 and LAB400-12-24F?

A: The primary difference is terminal type classification. LAB400-12-24 is classified as a Standard terminal connector, while LAB400-12-24F is classified as a Lug, Grounding terminal. All electrical and mechanical parameters are identical. The LAB400-12-24F is the manufacturer-recommended substitute and maintains Active product status.

Q: Are the mechanical dimensions identical between LAB400-12-24 and LAB400-12-24F?

A: Yes. Both parts have identical barrel ID (0.760"), barrel OD (1.190"), ring ID (0.530"), tab thickness (0.390"), overall length (6.940"), and outer width (1.610"). Mechanical fit and interface compatibility are fully equivalent.

Q: Can LAB400-12-24F be used in applications originally specified for LAB400-12-24?

A: Yes. The LAB400-12-24F is the manufacturer-recommended substitute. All critical electrical parameters (400MCM wire gauge, aluminum contact material, tin finish, crimp termination) and mechanical specifications are identical. Both parts support identical mounting and connection configurations.

Q: What is the wire gauge capacity for both parts?

A: Both LAB400-12-24 and LAB400-12-24F are rated for 400MCM (kcmil) wire gauge. This specification is identical and non-negotiable for substitution eligibility.

Q: Are both parts available in the same packaging?

A: LAB400-12-24 is available in standard packaging (packaging type not specified in available data). LAB400-12-24F is available in Bulk packaging. Both parts are currently in stock with comparable inventory levels (1165 Pcs and 993 Pcs respectively).

Q: What is the contact material and finish for these terminal connectors?

A: Both parts feature aluminum contact material with tin finish. This combination provides electrical conductivity and corrosion resistance suitable for high-amperage applications at 400MCM wire gauge.

Q: Why is LAB400-12-24 discontinued?

A: LAB400-12-24 is discontinued at DiGi Electronics. The manufacturer-recommended active substitute is LAB400-12-24F, which maintains identical electrical and mechanical specifications while ensuring continued availability and manufacturer support.
