Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 322764 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Stud/Tab Size: 1/2 Stud (fixed requirement)
• Wire Gauge Range: 300-350MCM (kcmil) coverage
• Termination Method: Crimp capability
• Contact Material: Copper
• Contact Finish: Tin
• Mounting Type: Free Hanging (In-Line)
• Insulation Type: Non-Insulated

The substitute parts listed (325805, 325805-1, and 325905) are all TE Connectivity AMP Connectors terminals that maintain the 1/2 stud configuration and crimp termination method. These substitutes differ in terminal geometry (rectangular versus circular) and wire gauge specificity, but satisfy the core electrical and mechanical interface requirements for the 1/2 stud mounting point and copper-tin contact system.

Parameter Comparison

Engineering Selection Recommendations

325805 and 325805-1 Selection: Both 325805 and 325805-1 are active-status terminals rated for 300MCM wire gauge with 1/2 stud configuration. These parts are ROHS3 compliant and maintain the copper-tin contact system required for the 322764 application. The 325805-1 variant provides higher inventory availability (1414 pcs) compared to 325805 (1083 pcs). Selection between these two identical specifications should be based on procurement lead time and inventory requirements.

325905 Selection: The 325905 terminal is rated for 350MCM wire gauge with identical 1/2 stud configuration and active product status. This part accommodates the upper wire gauge range of the original 322764 specification. ROHS3 compliance and copper-tin contact finish align with regulatory and electrical requirements.

Compliance Considerations: All substitute parts maintain RoHS compliance status and MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and storage requirements. The transition from the obsolete 322764 to active alternatives (325805, 325805-1, or 325905) eliminates supply chain risk while preserving electrical and mechanical interface specifications.

Frequently Asked Questions (FAQ)

Q: Can 325805 or 325805-1 directly replace 322764 in existing assemblies?

A: Both 325805 and 325805-1 share the critical 1/2 stud interface, crimp termination method, and copper-tin contact system with 322764. The primary difference is terminal geometry (rectangular versus circular). Mechanical fit at the stud connection point is maintained. Verification of available mounting space for the rectangular terminal geometry is necessary for specific applications.

Q: What is the difference between 325805 and 325805-1?

A: 325805 and 325805-1 are functionally identical terminals with the same electrical and mechanical specifications for 300MCM wire gauge and 1/2 stud configuration. The suffix designation (-1) indicates a variant within the same base product family (3258). Selection should be based on inventory availability and procurement requirements.

Q: When should 325905 be selected instead of 325805?

A: 325905 is specified for 350MCM wire gauge applications, representing the upper range of the original 322764 specification. If the application requires termination of 350MCM conductors, 325905 provides the appropriate barrel and contact sizing. For 300MCM applications, 325805 or 325805-1 are the correct selections.

Q: Are all substitute parts RoHS compliant?

A: Yes. 325805 and 325805-1 are ROHS3 compliant. 325905 is RoHS compliant. All parts maintain MSL rating of 1 (Unlimited), meeting current regulatory and manufacturing standards.

Q: What is the impact of terminal geometry change from circular to rectangular?

A: The substitute parts (325805, 325805-1, 325905) feature rectangular terminal geometry compared to the circular design of 322764. The 1/2 stud hole diameter remains constant at 0.515" (13.08mm) across all parts, ensuring stud connection compatibility. Rectangular geometry may affect available mounting space and mechanical clearance in the assembly. Physical layout verification is required for specific installations.

Q: Are the crimp barrel specifications compatible with existing crimping equipment?

A: All substitute parts feature crimp-barrel termination. Barrel dimensions vary by wire gauge: 325805 specifies 0.758" ID / 0.951" OD; 325905 specifies 0.819" ID / 1.026" OD. Crimping equipment must be rated for the specific barrel dimensions of the selected terminal. Existing equipment compatibility should be confirmed against the terminal specifications.
