Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 322894 is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Parameters:

• Terminal Type: Circular
• Stud/Tab Size: 1/4 Stud (mechanical interface requirement)
• Wire Gauge: 4 AWG (electrical current capacity)
• Termination Method: Crimp (assembly process compatibility)
• Contact Material: Copper (electrical conductivity)
• Contact Finish: Tin (corrosion resistance and solderability)
• Insulation: Insulated construction (safety and isolation)
• Features: Serrated Termination (mechanical grip consistency)

The substitute part TE Connectivity 54748-1 maintains equivalence across all critical parameters while offering active product status and improved compliance certifications. Both parts are manufactured by TE Connectivity AMP Connectors and share identical dimensional and electrical specifications for the functional interface points.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 54748-1

The TE Connectivity 54748-1 is the direct functional equivalent for applications currently specified with the 322894. This substitute maintains complete electrical and mechanical compatibility across all critical interface parameters including stud size, wire gauge, termination method, and contact specifications.

Compliance Advantages:

The 54748-1 offers ROHS3 compliance status compared to the non-compliant status of the 322894. This compliance improvement is significant for applications subject to RoHS regulations in the European Union and equivalent jurisdictions. Both parts maintain identical Moisture Sensitivity Level (MSL) ratings and export classification codes.

Product Status Consideration:

The 322894 is classified as obsolete, while the 54748-1 maintains active product status with TE Connectivity. Active status ensures continued availability, technical support, and manufacturing consistency. The 54748-1 is currently stocked with 2772 pieces in inventory compared to the 874 pieces available for the obsolete 322894.

Insulation Material Difference:

The substitute part utilizes Poly-Vinyl Chloride (PVC) insulation material compared to the vinyl insulation of the main part. Both materials provide equivalent electrical insulation properties and environmental protection. The PVC formulation in the 54748-1 represents current manufacturing standards for this connector series.

Frequently Asked Questions (FAQ)

Q: Are the 322894 and 54748-1 mechanically interchangeable?

A: Yes. Both parts feature identical 1/4 inch stud size, 0.048 inch thickness, and 0.546 inch outer edge width. The mechanical interface with mating components is identical, allowing direct substitution without design modification.

Q: What is the difference between the Ampli-Bond and Plasti-Grip series?

A: These designations identify different product series within TE Connectivity AMP Connectors. The Ampli-Bond series (322894) is obsolete, while the Plasti-Grip series (54748-1) represents the current active equivalent. Both series maintain identical electrical and mechanical specifications for this connector type.

Q: Does the insulation material change affect electrical performance?

A: No. Both vinyl and PVC insulation materials provide equivalent electrical insulation properties, dielectric strength, and environmental protection for 4 AWG crimp ring terminals. The material change reflects current manufacturing standards without affecting functional performance.

Q: Is the 54748-1 suitable for applications requiring RoHS compliance?

A: Yes. The 54748-1 carries ROHS3 compliance certification, making it suitable for applications subject to RoHS regulations. The 322894 is non-compliant and should not be used in RoHS-regulated applications.

Q: Can I use the 54748-1 in existing designs specified for the 322894?

A: Yes. The 54748-1 is a direct functional equivalent with identical electrical and mechanical specifications. No design changes are required for substitution in applications currently using the 322894.

Q: What is the wire gauge compatibility for both parts?

A: Both the 322894 and 54748-1 are specified for 4 AWG wire gauge. This specification determines the current-carrying capacity and wire termination interface. Both parts are not suitable for wire gauges other than 4 AWG.

Q: Are there any packaging differences between these parts?

A: The 322894 is supplied in standard packaging, while the 54748-1 is supplied in bulk packaging. Bulk packaging typically offers cost advantages for high-volume applications while maintaining identical component specifications.

Q: What is the stud size specification and why is it critical?

A: Both parts feature a 1/4 inch stud size, which defines the mechanical interface with mating components such as battery terminals, bus bars, or equipment connection points. This specification is critical for mechanical fit and electrical contact integrity.
