Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LAB500-12-2 is determined by alignment across the following critical parameters:

Primary Compatibility Criteria:

• Wire gauge capacity (500MCM kcmil)
• Stud/tab size (1/2 stud)
• Terminal style (two stud holes)
• Termination method (crimp, barrel)
• Mounting configuration (free hanging, in-line)

Secondary Compatibility Factors:

• Barrel inner diameter (ID) and outer diameter (OD) specifications
• Overall physical dimensions and tab thickness
• Contact material and finish properties
• Insulation classification

The substitute parts identified for LAB500-12-2 are categorized as follows:

Direct Substitute (LAB500-12-2R): Shares the same manufacturer series (LAB), stud size, terminal style, and termination method. Differs in wire gauge capacity (350MCM versus 500MCM) and terminal type classification (lug, grounding versus rectangular tongue). Maintains identical barrel dimensions and mounting configuration.

Similar Substitute (LCCF500-12-6): Matches wire gauge capacity (500MCM), stud size (1/2), terminal style (two stud holes), and termination method (crimp, barrel). Differs in contact material (copper versus aluminum), contact finish (electro-tin versus tin), and physical dimensions. Represents an active product from the Pan-Lug™ series with current availability.

Parameter Comparison

Engineering Selection Recommendations

LAB500-12-2R Selection Criteria:

The LAB500-12-2R is an active product with ROHS3 compliance and current inventory availability. This substitute maintains identical barrel dimensions (0.840" ID, 1.320" OD) and mounting configuration as the obsolete LAB500-12-2. The primary distinction is wire gauge capacity: LAB500-12-2R accommodates 350MCM wire, compared to 500MCM for the main part. Selection of LAB500-12-2R is appropriate for applications where 350MCM wire gauge requirements align with system specifications. The terminal type classification differs (lug, grounding versus rectangular tongue), which may affect mechanical fit and electrical performance characteristics in specific circuit configurations.

LCCF500-12-6 Selection Criteria:

The LCCF500-12-6 is an active product from the Pan-Lug™ series with ROHS3 compliance and higher inventory availability (1052 pieces). This substitute maintains identical wire gauge capacity (500MCM) and stud size (1/2) as the obsolete LAB500-12-2. The LCCF500-12-6 features copper contact material with electro-tin finish, compared to aluminum with tin finish in the main part. Barrel dimensions differ: LCCF500-12-6 specifies 1.030" ID and 1.550" OD, representing larger barrel cross-sections than the LAB500-12-2. Overall physical dimensions vary across length, width, and tab thickness parameters. Selection of LCCF500-12-6 is appropriate for applications requiring 500MCM wire gauge capacity with copper-based contact material and current product availability.

Compliance and Availability:

Both substitute parts carry REACH Unaffected status and ROHS3 compliance certification. The LAB500-12-2 (obsolete status) lacks specified RoHS documentation. Current inventory levels support procurement: LAB500-12-2R (721 pieces) and LCCF500-12-6 (1052 pieces).

Frequently Asked Questions (FAQ)

Q: Can LAB500-12-2R directly replace LAB500-12-2 in all applications?

A: LAB500-12-2R shares identical stud size, terminal style, termination method, and barrel dimensions with LAB500-12-2. However, wire gauge capacity differs: LAB500-12-2R is rated for 350MCM wire, while LAB500-12-2 is rated for 500MCM wire. Direct substitution is limited to applications where 350MCM wire gauge requirements are compatible with system specifications. Terminal type classification also differs (lug, grounding versus rectangular tongue), which may affect mechanical fit in specific mounting configurations.

Q: What are the key differences between LAB500-12-2 and LCCF500-12-6?

A: Both parts accommodate 500MCM wire gauge and feature 1/2 stud configuration with two stud holes. Primary differences include: contact material (aluminum versus copper), contact finish (tin versus electro-tin), barrel dimensions (0.840" ID/1.320" OD versus 1.030" ID/1.550" OD), and overall physical dimensions. LCCF500-12-6 represents an active product with current availability, while LAB500-12-2 is obsolete.

Q: Are barrel dimension differences between LAB500-12-2 and LCCF500-12-6 significant for compatibility?

A: Yes. Barrel inner diameter (ID) and outer diameter (OD) specifications determine wire crimp fit and electrical contact characteristics. LAB500-12-2 specifies 0.840" ID and 1.320" OD, while LCCF500-12-6 specifies 1.030" ID and 1.550" OD. These dimensional differences affect crimp tool compatibility and wire termination performance. Applications must verify that existing crimp tooling and wire termination procedures are compatible with the selected substitute part's barrel specifications.

Q: Do contact material differences affect electrical performance?

A: Contact material and finish properties influence electrical conductivity, corrosion resistance, and thermal characteristics. LAB500-12-2 features aluminum with tin finish, while LCCF500-12-6 features copper with electro-tin finish. Copper generally provides superior electrical conductivity compared to aluminum. Applications requiring specific electrical performance characteristics or corrosion resistance properties must evaluate whether contact material substitution aligns with system requirements.

Q: What is the significance of product status (obsolete versus active) for procurement?

A: Product status indicates manufacturing availability and long-term supply continuity. LAB500-12-2 carries obsolete status, indicating discontinued manufacturing and limited future availability. LAB500-12-2R and LCCF500-12-6 carry active status, indicating current production and sustained supply. For new designs or long-term procurement planning, active products provide greater supply security and manufacturing support.

Q: Are LAB500-12-2R and LCCF500-12-6 both suitable for the same application?

A: Suitability depends on specific application requirements. LAB500-12-2R accommodates 350MCM wire gauge, while LCCF500-12-6 accommodates 500MCM wire gauge. If the application requires 500MCM wire termination, LCCF500-12-6 is the appropriate selection. If the application requires 350MCM wire termination, LAB500-12-2R is appropriate. Barrel dimensions, contact material, and physical dimensions must also align with system specifications and existing tooling compatibility.

Q: What compliance certifications apply to these substitute parts?

A: Both LAB500-12-2R and LCCF500-12-6 carry REACH Unaffected status and ROHS3 compliance certification. These certifications indicate compliance with European Union environmental and hazardous substance regulations. The obsolete LAB500-12-2 does not specify RoHS documentation.
