MNG18-8R/LK Equivalent & Substitute Parts

Part Overview

The MNG18-8R/LK is a ring terminal connector manufactured by 3M, part of the Scotchlok™ series. This insulated circular terminal is designed for 18-22 AWG wire gauges with an #8 stud connection, featuring crimp termination and tin-plated copper contact material. The component is Active status and RoHS Compliant, making it suitable for applications requiring reliable ring terminal connections in electrical assemblies. Substitute parts may be required due to inventory availability, supply chain considerations, or specific packaging requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MNG18-8R/LK is determined by the following critical parameters:

• Terminal Type & Stud Size: Must be circular terminal with #8 stud connection
• Wire Gauge Compatibility: Must accommodate 18-22 AWG wire range
• Termination Method: Must use crimp termination
• Insulation Type: Must be insulated with polyamide/nylon material
• Contact Material & Finish: Must use copper with tin finish
• Mounting Configuration: Must be free hanging (in-line) type
• Regulatory Compliance: Must maintain RoHS compliance status

The identified substitute parts meet these core electrical and mechanical parameters, ensuring functional equivalence in standard ring terminal applications.

Parameter Comparison

Engineering Selection Recommendations

All three components maintain Active product status and RoHS compliance, confirming their suitability for current applications. The MNG18-8R/LK (3M Scotchlok™) and PNF18-8R-M (Panduit Pan-Term®) share identical wire gauge specifications (18-22 AWG), making them direct functional equivalents. The 1-320551-1 (TE Connectivity PIDG) accommodates a broader wire gauge range (16-22 AWG), providing compatibility with applications requiring 16 AWG wire termination while maintaining all other critical parameters.

Dimensional variations across the three parts are minor and within acceptable tolerances for standard ring terminal applications. Selection should be based on packaging availability, inventory status, and specific application requirements rather than performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 1-320551-1 substitute for MNG18-8R/LK in all applications?

A: The 1-320551-1 is functionally compatible for applications using 18-22 AWG wire. Its extended wire gauge range (16-22 AWG) does not restrict its use in standard 18-22 AWG applications. However, verify that the serrated termination feature and slightly different dimensional specifications meet your specific assembly requirements.

Q: What is the primary difference between the MNG18-8R/LK and PNF18-8R-M?

A: Both parts share identical wire gauge (18-22 AWG), stud size (#8), and termination method (crimp). The PNF18-8R-M includes serrated termination and differs slightly in overall length (0.870" vs 0.920") and thickness (0.032" vs 0.030"). These differences do not affect electrical performance in standard applications.

Q: Are there packaging differences between these substitute parts?

A: Yes. The MNG18-8R/LK and PNF18-8R-M are supplied in Bulk packaging, while the 1-320551-1 is supplied in Cut Tape (CT) packaging. Select based on your assembly process requirements and inventory management practices.

Q: Do all three parts meet the same regulatory standards?

A: All three parts are RoHS compliant and carry EAR99 ECCN classification. The MNG18-8R/LK is RoHS Compliant, while both substitute parts are ROHS3 Compliant, representing equivalent regulatory status for current applications.

Q: What determines whether a ring terminal can substitute for the MNG18-8R/LK?

A: Substitution requires matching the following parameters: circular terminal type, #8 stud size, 18-22 AWG wire gauge compatibility, crimp termination, insulated polyamide/nylon construction, copper with tin finish contact material, and free hanging in-line mounting configuration.
