TE Connectivity AMP Connectors 322051 Ring Terminal Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 322051 is a ring terminal connector designed for 6 AWG wire gauge applications with a 1/4 inch stud connection. This insulated circular terminal features crimp termination and is part of the Ampli-Bond series. The 322051 is classified as obsolete, making identification of suitable substitute components necessary for ongoing procurement and system maintenance. The part is constructed with copper contact material, tin finish, and vinyl insulation, rated for unlimited moisture sensitivity conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 322051 is determined by strict equivalence across the following critical parameters: wire gauge (6 AWG), stud size (1/4 inch), terminal type (circular), termination method (crimp), contact material (copper), contact finish (tin), and insulation classification (insulated). The substitute part 324047 meets all these core electrical and mechanical requirements. Both parts accommodate identical wire gauges and stud configurations, ensuring mechanical and electrical compatibility in applications requiring ring terminal connectors for 6 AWG conductors on 1/4 inch studs.

Dimensional variations exist between the main part and substitute, specifically in overall length and insulation diameter. These variations do not affect functional substitution when the primary electrical and mechanical interfaces remain constant. The substitute part operates within the same moisture sensitivity level (MSL 1 - Unlimited) and maintains equivalent contact material specifications.

Parameter Comparison

Engineering Selection Recommendations

The 322051 is classified as obsolete, establishing the primary justification for substitute part selection. The 324047 is an active product from the same manufacturer, TE Connectivity AMP Connectors, and maintains full electrical and mechanical compatibility across all critical parameters.

From a regulatory compliance perspective, the 324047 offers significant advantages. It is ROHS3 compliant, whereas the 322051 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 324047 is the appropriate selection.

Both parts share identical wire gauge (6 AWG), stud size (1/4 inch), contact material (copper), contact finish (tin), and termination method (crimp). The insulation material differs between vinyl (322051) and polyamide/nylon (324047), with the polyamide option offering enhanced chemical and thermal resistance characteristics. The overall length difference of 0.152 inches (3.86mm) and insulation diameter difference of 0.063 inches (1.60mm) do not compromise functional substitution in standard ring terminal applications.

The 324047 is available in bulk packaging with significantly higher inventory levels (2489 pieces) compared to the 322051 (835 pieces), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 324047 directly replace the 322051 in existing applications?

A: Yes. Both parts meet identical specifications for wire gauge (6 AWG), stud size (1/4 inch), terminal type (circular), contact material (copper), contact finish (tin), and crimp termination. The dimensional variations in overall length and insulation diameter do not affect functional compatibility in standard ring terminal installations.

Q: What is the primary reason for substitution?

A: The 322051 is classified as obsolete. The 324047 is an active product from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: Yes. The 324047 is ROHS3 compliant, while the 322051 is RoHS non-compliant. Applications requiring RoHS compliance must use the 324047.

Q: How do the insulation materials differ?

A: The 322051 uses vinyl insulation, while the 324047 uses polyamide (PA) nylon insulation. Polyamide offers superior chemical and thermal resistance. Both materials are suitable for MSL 1 (unlimited moisture sensitivity) applications.

Q: What packaging options are available?

A: The 322051 is supplied in standard packaging, while the 324047 is available in bulk packaging. The 324047 offers higher inventory availability (2489 pieces versus 835 pieces).

Q: Are the electrical specifications identical?

A: Yes. Both parts are rated for 6 AWG wire gauge, feature copper contacts with tin finish, and employ crimp termination with serrated termination features. Electrical performance is equivalent.

Q: What are the dimensional differences?

A: The 324047 has a shorter overall length (1.700 inches versus 1.852 inches) and smaller insulation diameter (0.314 inches versus 0.377 inches). These differences do not affect compatibility with 1/4 inch studs or standard ring terminal applications.
