TE Connectivity AMP Connectors 323974 Ring Terminal Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 323974 is an insulated ring terminal connector designed for 8 AWG wire gauge applications with a #10 stud connection. This component features a flat-sided terminal geometry and crimp termination method, classified within the Ampli-Bond series. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs. Substitute parts must maintain compatibility across critical electrical and mechanical parameters including wire gauge, stud size, termination method, and contact specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the TE Connectivity 323974 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Wire Gauge: 8 AWG
• Stud/Tab Size: #10 Stud
• Termination Method: Crimp
• Contact Material: Copper
• Contact Finish: Tin
• Insulation Status: Insulated
• Mounting Type: Free Hanging (In-Line)
• Thickness: 0.040" (1.02mm)
• Serrated Termination Feature: Present

Allowable Variations:

• Terminal geometry (flat-sided versus circular)
• Insulation material composition (vinyl versus polyamide/nylon)
• Overall length and width dimensions
• Insulation diameter
• Product series designation
• Packaging configuration
• Product status and compliance certifications

The substitute part TE Connectivity 324043 satisfies all mandatory matching parameters while introducing geometric and material variations that do not affect functional compatibility in standard ring terminal applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 324043

The TE Connectivity 324043 serves as the functional equivalent for the obsolete 323974 across all critical electrical and mechanical parameters. Both components share identical wire gauge (8 AWG), stud size (#10), termination method (crimp), contact material and finish (copper with tin plating), and thickness specifications.

Compliance Considerations:

The 324043 holds active product status with ROHS3 compliance certification, whereas the 323974 is obsolete and RoHS non-compliant. For applications subject to RoHS regulatory requirements or requiring components with current manufacturer support, the 324043 is the appropriate selection.

Geometric Variations:

The substitute part features a circular terminal geometry compared to the flat-sided design of the main part. This geometric difference does not affect functional compatibility in standard ring terminal applications where the terminal connects to a #10 stud. The circular design of the 324043 provides equivalent electrical performance and mechanical retention.

The insulation material differs between parts (vinyl in 323974 versus polyamide/nylon in 324043). Both materials provide adequate insulation for the specified application parameters. The polyamide insulation in the 324043 offers enhanced thermal and chemical resistance characteristics.

Inventory and Availability:

The 324043 maintains active inventory status with 1978 pieces available, ensuring supply chain continuity for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 324043 directly replace the 323974 in existing applications?

A: Yes. Both components meet identical specifications for wire gauge (8 AWG), stud size (#10), crimp termination, copper contact material with tin finish, and thickness (0.040"). The geometric difference between flat-sided and circular terminal designs does not affect functional compatibility in standard ring terminal mounting applications.

Q: What is the significance of the terminal geometry difference?

A: The flat-sided terminal in the 323974 and circular terminal in the 324043 represent different manufacturing approaches for the same functional purpose. Both geometries provide equivalent electrical conductivity and mechanical retention when crimped to 8 AWG wire and mounted on a #10 stud. Terminal geometry selection depends on specific application space constraints and mounting preferences rather than electrical performance.

Q: Why is the 323974 listed as obsolete?

A: The 323974 is classified as obsolete within the TE Connectivity product portfolio. The 324043 represents the current active equivalent within the Terminyl series, offering the same core functionality with updated compliance certifications and manufacturing standards.

Q: Does the insulation material change affect performance?

A: Both vinyl (323974) and polyamide/nylon (324043) insulation materials provide adequate electrical insulation for the specified application. The polyamide insulation in the 324043 offers enhanced resistance to thermal cycling and chemical exposure. Material selection does not impact electrical performance in standard operating conditions.

Q: What is the impact of RoHS compliance differences?

A: The 323974 is RoHS non-compliant, while the 324043 is ROHS3 compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the 324043 is the required selection. For legacy applications without RoHS requirements, both parts function identically.

Q: Are there packaging differences between these parts?

A: The 324043 is supplied in bulk packaging, while the 323974 packaging specification is not provided. Bulk packaging typically offers cost advantages for high-volume applications. Packaging configuration does not affect component performance or compatibility.

Q: What wire gauge and stud size combinations are supported?

A: Both the 323974 and 324043 are specifically designed for 8 AWG wire gauge with #10 stud connections. These specifications are fixed and not variable. Applications requiring different wire gauge or stud size combinations require alternative part numbers outside this equivalency group.
