Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 94764 is determined by the following critical parameters:

• Wire gauge compatibility: 4 AWG
• Terminal configuration: Circular ring terminal
• Stud size: 1/2 inch
• Termination method: Crimp
• Insulation material: Polyamide nylon
• Contact material: Copper-based with tin finish
• Mounting configuration: Free-hanging in-line

The Molex 0190670085 qualifies as a substitute based on matching all critical electrical and mechanical parameters. Both parts accommodate 4 AWG wire, feature circular ring terminal geometry with 1/2 stud configuration, utilize crimp termination, and employ nylon insulation with copper contacts.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0190670085 serves as the primary substitute for the obsolete 3M 94764. Both parts meet RoHS compliance requirements and maintain identical moisture sensitivity levels. The Molex component carries active product status, ensuring continued availability and supply chain reliability.

Dimensional variations exist between the two parts. The Molex 0190670085 exhibits greater overall length (2.531" versus 1.740") and width (0.885" versus 0.680"), while maintaining slightly reduced thickness (0.070" versus 0.075"). These dimensional differences do not affect electrical performance or stud compatibility but may require verification in space-constrained applications.

Both parts employ tin-plated copper contacts suitable for general electrical connectivity applications. The Molex component utilizes electro-tin plating, while the 3M original uses standard tin plating. Contact finish differences do not impact functional equivalence for standard circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0190670085 directly replace the 3M 94764 in existing assemblies?

A: Yes, the Molex 0190670085 qualifies as a direct substitute based on matching wire gauge (4 AWG), terminal type (circular), stud size (1/2 inch), and termination method (crimp). Both parts feature identical insulation material and contact material composition.

Q: What dimensional differences exist between these parts?

A: The Molex 0190670085 is longer (2.531" versus 1.740") and wider (0.885" versus 0.680") than the 3M 94764, with slightly reduced thickness (0.070" versus 0.075"). Verify clearance in confined mounting spaces before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The 3M 94764 is RoHS Compliant, and the Molex 0190670085 is ROHS3 Compliant. Both meet current regulatory requirements.

Q: What is the difference between tin and electro-tin plating?

A: Both finishes provide tin-based contact protection. Electro-tin plating, used on the Molex part, is applied through electrochemical deposition. Standard tin plating, used on the 3M part, is applied through alternative methods. Both finishes deliver equivalent electrical performance for this application category.

Q: Why is the 3M 94764 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Molex 0190670085 maintains active product status, providing assured supply availability for new designs and replacement requirements.

Q: Are there packaging differences between these parts?

A: The 3M 94764 is supplied in standard packaging, while the Molex 0190670085 is supplied in bulk packaging. Verify packaging requirements for your procurement process.
