TE Connectivity AMP Connectors 322252 Ring Terminal Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 322252 is a ring terminal connector designed for high-amperage applications. This component features a circular terminal configuration with a 3/8 inch stud, rated for 250-300MCM (kcmil) wire gauges, and utilizes crimp termination with a brazed seam construction. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for new designs and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 322252 ring terminal is determined by the following critical parameters: stud size (3/8 inch), wire gauge compatibility (250-300MCM range), termination method (crimp), contact material (copper), contact finish (tin), insulation type (non-insulated), and mounting configuration (free hanging in-line).

The substitute parts identified are rectangular terminal connectors from the active Ampower series that maintain these core electrical and mechanical specifications. While the terminal geometry transitions from circular to rectangular, the functional interface remains compatible: all substitutes feature the same 3/8 inch stud hole diameter (0.390 inch ring ID), identical contact material and finish, equivalent wire gauge ratings within the 250-300MCM range, and matching crimp barrel termination methodology. The substitutes are active products with current manufacturing status and full RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The obsolete status of part 322252 requires transition to active substitute components. All three identified substitutes (325703, 325803, and 325803-1) are manufactured by TE Connectivity AMP Connectors and maintain active product status with current manufacturing support.

For applications requiring 250MCM wire gauge capacity, part 325703 is the appropriate selection. This component is RoHS Compliant and carries full compliance certification.

For applications requiring 300MCM wire gauge capacity, both 325803 and 325803-1 are functionally equivalent. Part 325803 carries ROHS3 Compliant certification, while 325803-1 carries RoHS Compliant certification. Both maintain identical electrical and mechanical specifications, with 325803-1 offering higher current inventory availability (1368 pieces versus 932 pieces).

All substitute parts maintain the critical 3/8 inch stud interface, copper contact material with tin finish, non-insulated construction, and free-hanging in-line mounting configuration required for direct functional replacement of the 322252 ring terminal.

Frequently Asked Questions (FAQ)

Q: Can the 322252 ring terminal be directly replaced with a rectangular terminal substitute?

A: Yes. While the terminal geometry differs from circular to rectangular, the functional interface is identical. The critical stud hole diameter (0.390 inch) remains constant across all substitutes, ensuring mechanical compatibility with existing stud assemblies. The electrical performance is maintained through equivalent copper contact material, tin finish, and crimp barrel termination.

Q: What is the difference between 325803 and 325803-1?

A: Parts 325803 and 325803-1 are functionally identical in all electrical and mechanical specifications. Both are rated for 300MCM wire gauge with 3/8 inch studs, identical dimensions, and matching contact materials and finishes. The primary difference is RoHS certification status (ROHS3 Compliant versus RoHS Compliant) and inventory availability. Selection between these parts depends on specific regulatory requirements and supply chain considerations.

Q: Which substitute should be selected for a 250-300MCM application?

A: The 322252 original part accommodates the full 250-300MCM range within a single component. Substitution requires selection based on the specific wire gauge of the application. For 250MCM applications, select 325703. For 300MCM applications, select either 325803 or 325803-1.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts carry RoHS compliance certification. Part 325803 carries ROHS3 Compliant status, while 325703 and 325803-1 carry RoHS Compliant status. All meet current environmental and regulatory requirements.

Q: What is the significance of the barrel termination method on the substitute parts?

A: The substitute parts utilize crimp barrel termination, which is the standard termination methodology for high-amperage terminal connectors in this wire gauge range. This method provides secure, low-resistance connections suitable for 250-300MCM applications and is fully compatible with standard crimping equipment used for the original 322252 component.

Q: Do the substitute parts maintain the same stud interface as the original 322252?

A: Yes. All substitute parts feature a 0.390 inch (9.91mm) ring ID diameter, which corresponds to the 3/8 inch stud specification. This ensures mechanical compatibility with existing stud assemblies and mounting hardware without modification.
