Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 322011 with active equivalent components is based on strict alignment of the following critical parameters:

Wire gauge compatibility (4 AWG) ensures proper current-carrying capacity and crimp tool compatibility. The 3/8 inch stud size maintains mechanical fit with existing connector assemblies and mating hardware. Circular terminal geometry and crimp termination method preserve electrical connection integrity and installation procedures. Insulated construction with copper contact material and tin finish maintains corrosion resistance and electrical performance. Serrated termination features ensure consistent mechanical retention within the crimp joint.

The substitute part 324052 satisfies all mandatory compatibility criteria while offering active product status and improved compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 324052 serves as the direct functional equivalent to the obsolete 322011. Both components share identical wire gauge, stud size, terminal geometry, and termination methodology. The 324052 maintains all critical electrical and mechanical parameters required for direct substitution in existing applications.

The 324052 offers the advantage of active product status, ensuring continued availability and supply chain reliability. The component achieves ROHS3 compliance, meeting current regulatory requirements for new designs and procurement cycles. The substitute utilizes polyamide (PA) nylon insulation material compared to the vinyl insulation of the original part, providing enhanced thermal and chemical resistance characteristics within the specified parameter set.

Both components carry identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications, maintaining consistent export and tariff treatment. Moisture sensitivity level remains at MSL 1 (Unlimited) for both parts, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 324052 directly replace the 322011 in existing assemblies?

A: Yes. The 324052 maintains identical wire gauge (4 AWG), stud size (3/8 inch), terminal type (circular), and termination method (crimp). All critical mechanical and electrical parameters align with the original specification.

Q: What is the primary reason for substitution?

A: The 322011 is classified as obsolete. The 324052 is an active product offering equivalent functionality with current manufacturing support and compliance certification.

Q: Are there differences in physical dimensions between the two parts?

A: The overall length differs slightly: 322011 measures 1.974 inches (50.14mm) while 324052 measures 1.878 inches (47.70mm). The insulation diameter also differs: 322011 is 0.436 inches (11.07mm) versus 324052 at 0.382 inches (9.70mm). These dimensional variations do not affect stud compatibility or crimp termination performance.

Q: What insulation material differences exist?

A: The 322011 uses vinyl insulation while the 324052 uses polyamide (PA) nylon insulation. Both are rated for MSL 1 (Unlimited) moisture sensitivity and maintain equivalent electrical performance within the specified application parameters.

Q: Does the 324052 meet current compliance standards?

A: Yes. The 324052 is ROHS3 compliant, whereas the 322011 is RoHS non-compliant. Both components carry identical ECCN and HTSUS classifications.

Q: What packaging differences exist?

A: The 322011 original packaging specification is not defined in available data. The 324052 is supplied in bulk packaging format.

Q: Are crimp tool specifications identical for both parts?

A: Both components utilize crimp termination for 4 AWG wire gauge. Crimp tool selection is determined by wire gauge and terminal design, which remain consistent between the two parts.
