Key Parameters

Substitute Part Grouping Explanation

Substitution of the 322049 is based on strict equivalence of core electrical and mechanical parameters. The substitute part 324082 maintains compatibility through the following critical parameters:

Electrical Compatibility Parameters:

• Wire gauge: 8 AWG (identical)
• Contact material: Copper (identical)
• Contact finish: Tin (identical)
• Termination method: Crimp (identical)

Mechanical Compatibility Parameters:

• Terminal type: Circular (identical)
• Stud/Tab size: 1/4 Stud (identical)
• Mounting type: Free Hanging (In-Line) (identical)
• Insulation status: Insulated (identical)
• Features: Serrated termination (identical)

Dimensional Compatibility:

• Thickness: 0.040" (1.02mm) (identical)
• Width - Outer Edges: 0.478" (12.14mm) (identical)

The 324082 substitute differs in insulation material composition, overall length, and insulation diameter, but these variations do not affect functional compatibility for the specified 8 AWG 1/4 stud ring terminal application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 324082

The 324082 is the direct functional equivalent for the obsolete 322049. Selection of the 324082 is based on the following engineering criteria:

Product Status Consideration: The 322049 is classified as obsolete, while the 324082 maintains active product status with TE Connectivity AMP Connectors. Active status ensures ongoing availability, technical support, and manufacturing consistency.

Compliance and Certification: The 324082 is ROHS3 compliant, providing enhanced environmental compliance compared to the non-compliant 322049. Both parts maintain identical MSL ratings of 1 (Unlimited) and share the same ECCN and HTSUS classifications, indicating equivalent regulatory treatment for export and tariff purposes.

Functional Equivalence: The 324082 maintains all critical electrical and mechanical parameters: 8 AWG wire gauge, 1/4 stud connection, copper contact with tin finish, crimp termination, and serrated termination features. The circular terminal type and free-hanging in-line mounting configuration remain unchanged.

Physical Compatibility: Outer dimensions critical to mechanical fit are preserved: thickness of 0.040" (1.02mm) and width of 0.478" (12.14mm) remain identical. The overall length reduction from 1.586" to 1.425" and insulation diameter change from 0.298" to 0.256" reflect the transition from vinyl to polyamide insulation material but do not compromise functional compatibility for standard 8 AWG applications.

Frequently Asked Questions (FAQ)

Q: Can the 324082 directly replace the 322049 in existing applications?

A: Yes. The 324082 maintains identical wire gauge (8 AWG), stud size (1/4 inch), contact material (copper), contact finish (tin), and termination method (crimp). The circular terminal type and serrated termination features are preserved. The substitute is mechanically and electrically compatible for all standard 8 AWG ring terminal applications.

Q: What is the significance of the insulation material change from vinyl to polyamide?

A: The 324082 uses polyamide (PA) nylon insulation instead of vinyl. Both materials provide adequate insulation for the specified application. The polyamide material in the 324082 contributes to its ROHS3 compliance status. The insulation diameter reduction from 0.298" to 0.256" reflects the different material properties but does not affect electrical performance or stud connection compatibility.

Q: Why is the 322049 listed as obsolete?

A: The 322049 is classified as obsolete by TE Connectivity AMP Connectors. The 324082 represents the current active product offering for this terminal configuration and should be used for new designs and ongoing procurement.

Q: Are there packaging differences between the 322049 and 324082?

A: The 322049 was supplied in standard packaging, while the 324082 is available in bulk packaging. Bulk packaging does not affect the terminal specifications or performance characteristics.

Q: Do both parts meet the same regulatory requirements?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications. The 324082 provides enhanced environmental compliance through ROHS3 certification, while the 322049 is non-compliant. Both maintain MSL rating of 1 (Unlimited), indicating identical moisture sensitivity performance.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: wire gauge (8 AWG), stud size (1/4 inch), terminal type (circular), contact material (copper), contact finish (tin), termination method (crimp), and insulation status (insulated). The 324082 maintains all these parameters identically to the 322049.
