MNG18-8FLK Equivalent & Substitute Parts

Part Overview

The MNG18-8FLK is a red insulated spade terminal connector manufactured by 3M, designed for crimp termination of 18-22 AWG wire onto #8 studs. This component is part of the Scotchlok™ series and maintains Active product status with full RoHS compliance. Alternative equivalent parts may be required due to supply chain considerations, inventory availability, or specific application requirements where mechanical or electrical parameters align within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MNG18-8FLK is permissible with parts that maintain identical or functionally equivalent parameters across the following critical criteria:

Wire gauge compatibility (18-22 AWG) ensures proper current-carrying capacity and crimp tool compatibility. Stud size (#8) is non-negotiable for mechanical fit on the mating connector. Insulation diameter (0.145" / 3.68mm) must match to ensure proper seating and strain relief. Contact material (copper with tin finish) and termination method (crimp) are fixed requirements. Color coding (red) indicates voltage class and must be preserved. RoHS compliance status ensures regulatory alignment for the application environment.

The substitute part PNF18-8LF-M from Panduit Corp satisfies all critical parameters within acceptable engineering tolerances for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both MNG18-8FLK and PNF18-8LF-M maintain Active product status and satisfy RoHS compliance requirements. The MNG18-8FLK carries RoHS Compliant certification, while the PNF18-8LF-M carries ROHS3 Compliant certification, both meeting current regulatory standards. Both parts are REACH Unaffected and classified under identical HTSUS and ECCN codes, confirming regulatory equivalence.

Selection between these parts should be based on availability, lead time, and inventory position. The PNF18-8LF-M currently maintains higher inventory levels (1639 pcs vs. 826 pcs), which may influence procurement decisions. Dimensional variations in width and overall length fall within acceptable mechanical tolerances for free-hanging in-line applications.

Frequently Asked Questions (FAQ)

Q: Can PNF18-8LF-M replace MNG18-8FLK in existing designs?

A: Yes. Both parts share identical wire gauge (18-22 AWG), stud size (#8), insulation diameter (0.145"), contact material (copper with tin finish), and termination method (crimp). Dimensional variations in width (0.010" difference) and length (0.020" difference) are within acceptable tolerances for free-hanging connector applications.

Q: Are there differences in insulation material?

A: No. Both parts use Polyamide (PA) Nylon insulation with identical diameter specifications (0.145" / 3.68mm).

Q: What is the significance of the "Butted Seam" feature on the Panduit part?

A: The Butted Seam feature on PNF18-8LF-M is a manufacturing characteristic that does not affect electrical or mechanical compatibility. It represents a design variation between manufacturers but does not impact substitution suitability.

Q: Do both parts meet current compliance standards?

A: Yes. MNG18-8FLK is RoHS Compliant, and PNF18-8LF-M is ROHS3 Compliant. Both are REACH Unaffected and carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications.

Q: Are there any packaging or bulk quantity considerations?

A: Both parts are supplied in Bulk packaging. Inventory availability differs: MNG18-8FLK has 826 pcs in stock, while PNF18-8LF-M has 1639 pcs available. Procurement should account for lead times and minimum order quantities specific to each supplier.
