Substitute Part Grouping Explanation

The Panduit Corp LCA4-10-L qualifies as a substitute for the 3M 30018 based on the following critical parameters:

• Stud/Tab Size Compatibility: Both parts feature #10 stud connection, ensuring mechanical compatibility with mating components
• Wire Gauge Range: The LCA4-10-L accommodates 2-4 AWG wire, which includes the 4 AWG specification of the main part
• Termination Method: Both utilize crimp barrel termination, maintaining process compatibility
• Contact Material and Finish: Both employ copper contact material with electro-tin finish, ensuring electrical performance equivalence
• Mounting Configuration: Both are free hanging (in-line) terminals with single stud hole design
• Non-Insulated Classification: Both are non-insulated terminals
• Regulatory Compliance: Both maintain RoHS and REACH compliance status

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 30018 and Panduit LCA4-10-L maintain Active product status and full regulatory compliance. The LCA4-10-L is designated as the manufacturer-recommended substitute. Selection between these components should be based on:

• Availability: The LCA4-10-L currently maintains higher inventory levels (1143 pcs vs. 837 pcs)
• Wire Gauge Flexibility: The LCA4-10-L accommodates a broader wire gauge range (2-4 AWG) compared to the fixed 4 AWG specification of the 30018
• Dimensional Variations: The LCA4-10-L features different barrel dimensions and overall length; verify mechanical fit within the application assembly
• Regulatory Tier: The LCA4-10-L meets ROHS3 compliance, representing a more current regulatory standard than RoHS Compliant

Frequently Asked Questions (FAQ)

Q: Can the Panduit LCA4-10-L directly replace the 3M 30018 in existing assemblies?

A: The LCA4-10-L is mechanically and electrically compatible based on matching stud size (#10), termination method (crimp barrel), contact material (copper with electro-tin finish), and regulatory compliance. However, dimensional differences in barrel diameter and overall length require verification of fit within the specific application assembly.

Q: What is the primary difference between these two terminal types?

A: The 3M 30018 is classified as a Standard terminal, while the Panduit LCA4-10-L is a Rectangular Tongue terminal. Both function as rectangular connectors with equivalent electrical performance for the specified wire gauge and stud connection.

Q: Are both parts non-insulated?

A: Yes, both the 3M 30018 and Panduit LCA4-10-L are non-insulated terminals, requiring external insulation management in the application circuit.

Q: Do both parts meet current regulatory requirements?

A: Both parts maintain REACH Unaffected status. The 3M 30018 is RoHS Compliant, while the Panduit LCA4-10-L meets the more current ROHS3 Compliant standard.

Q: What wire gauge range is supported by each part?

A: The 3M 30018 is specified for 4 AWG wire. The Panduit LCA4-10-L accommodates 2-4 AWG wire, providing broader application flexibility.

Q: Are the barrel dimensions identical between these parts?

A: No. The 3M 30018 has a barrel ID of 0.247" (6.27mm) and OD of 0.340" (8.64mm). The Panduit LCA4-10-L has a barrel ID of 0.280" (7.11mm) and OD of 0.380" (9.65mm). These dimensional differences must be considered for mechanical compatibility.
