Substitute Part Grouping Explanation

Substitution of the LAB4/0-12-5R is based on electrical and mechanical parameter equivalence within the Panduit LAB series aluminum compression lug family. The substitute part LAB4/0-12-ER maintains identical specifications across all critical parameters that determine functional compatibility:

Critical Substitution Parameters:

• Wire gauge: 4/0 AWG
• Stud size: 1/2 inch
• Terminal style: Two stud holes
• Termination method: Crimp
• Contact material: Aluminum
• Contact finish: Tin
• Barrel dimensions: ID 0.550" (13.97mm), OD 0.880" (22.35mm)
• Ring ID: 0.530" (13.46mm)
• Tab thickness: 0.310" (7.87mm)
• Insulation: Non-insulated
• Compliance: ROHS3 compliant

The LAB4/0-12-ER is an active product with current manufacturing status and available inventory, providing direct functional replacement for the discontinued LAB4/0-12-5R.

Parameter Comparison

Engineering Selection Recommendations

The LAB4/0-12-ER is the direct substitute for the discontinued LAB4/0-12-5R. Both parts are ROHS3 compliant and maintain identical electrical and mechanical specifications across all critical parameters. The LAB4/0-12-ER is currently active in production with available inventory, making it the appropriate selection for new designs and replacement applications.

The substitute part is manufactured by the same original equipment manufacturer (Panduit Corp) within the same LAB series, ensuring design continuity and compatibility with existing circuit designs and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can LAB4/0-12-ER be used as a direct replacement for LAB4/0-12-5R?

A: Yes. The LAB4/0-12-ER maintains identical electrical and mechanical specifications including wire gauge (4/0 AWG), stud size (1/2 inch), barrel dimensions, ring ID, tab thickness, contact material (aluminum), contact finish (tin), and termination method (crimp). Both parts are non-insulated and ROHS3 compliant.

Q: What is the difference between the LAB4/0-12-5R and LAB4/0-12-ER?

A: The primary difference is product status. The LAB4/0-12-5R is discontinued at DiGi Electronics, while the LAB4/0-12-ER is an active product with current manufacturing and available inventory. The terminal type designation differs (Grounding versus Standard), but all functional electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The LAB4/0-12-5R packaging information is not specified in available documentation. The LAB4/0-12-ER is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LAB4/0-12-5R and LAB4/0-12-ER are ROHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8536.90.4000.

Q: What wire gauge does this terminal accommodate?

A: Both parts are rated for 4/0 AWG wire gauge with a barrel inner diameter of 0.550 inches (13.97mm) and outer diameter of 0.880 inches (22.35mm).

Q: Is this terminal suitable for grounding applications?

A: Yes. The LAB4/0-12-5R is designated as a grounding lug. The LAB4/0-12-ER is designated as a standard terminal but maintains identical specifications and is functionally equivalent for grounding circuit applications.
