TE Connectivity AMP Connectors 32957 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 32957 is an insulated ring terminal connector designed for circular stud applications. This component features a 6 stud configuration with crimp termination suitable for 14-16 AWG wire gauges. The part is classified as Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Ring terminal connectors are essential components in electrical assemblies where secure, permanent wire termination to circular studs is required. Substitute parts are identified when inventory constraints, lead time requirements, or specific application parameters necessitate alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 32957 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Terminal Type: Circular ring configuration
• Stud/Tab Size: 6 Stud mounting point
• Termination Method: Crimp connection
• Insulation: Insulated construction
• Contact Material: Copper-based with tin finish
• Regulatory Compliance: ROHS3 compliant status
• Moisture Sensitivity: MSL 1 rating

Secondary Variation Parameters:

• Wire Gauge Range: Acceptable variance in AWG rating based on application requirements
• Physical Dimensions: Outer width, length, and thickness may vary within acceptable tolerances
• Insulation Material: Alternative vinyl or PVC formulations
• Color Coding: Variation in insulation color does not affect electrical function

The substitute part Keystone Electronics 8215 maintains the core functional parameters (circular terminal type, 6 stud configuration, crimp termination, insulated construction, copper contact with tin finish, and ROHS3 compliance) while operating within a different wire gauge specification (10-12 AWG versus 14-16 AWG).

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity AMP Connectors 32957 is the primary specification for applications requiring 14-16 AWG wire termination to 6 stud circular ring terminals. This part maintains Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory adherence.

Keystone Electronics 8215 serves as a substitute option for applications where wire gauge requirements differ. This part is specified for 10-12 AWG wire termination and maintains equivalent compliance certifications (ROHS3 compliant, MSL 1, EAR99 classification). Both parts share identical stud configuration, termination method, and regulatory status.

Selection between these parts is determined by wire gauge requirements of the specific application. The 32957 accommodates smaller diameter conductors (14-16 AWG), while the 8215 accommodates larger diameter conductors (10-12 AWG). Physical dimension variations between the parts reflect the different wire gauge specifications and do not indicate functional incompatibility when applied to their respective wire gauge ranges.

Both parts are Active status products with established supply chains and full compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 8215 be used as a direct replacement for the TE Connectivity 32957?

A: Direct replacement is not applicable. The 8215 is specified for 10-12 AWG wire, while the 32957 is specified for 14-16 AWG wire. Substitution is only valid when the application wire gauge matches the substitute part specification. Using an incorrectly sized terminal for the wire gauge will result in improper crimp connection and potential electrical failure.

Q: What are the core compatibility parameters for ring terminal substitution?

A: The following parameters must remain constant for functional substitution: terminal type (circular), stud size (6 stud), termination method (crimp), insulation presence, contact material (copper-based), and contact finish (tin). Wire gauge, physical dimensions, and insulation material color may vary based on application requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the TE Connectivity 32957 and Keystone Electronics 8215 are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings. Both parts carry EAR99 export classification and 8536.90.4000 HTSUS code.

Q: What is the difference in wire gauge between these parts?

A: The TE Connectivity 32957 is rated for 14-16 AWG wire, accommodating smaller diameter conductors. The Keystone Electronics 8215 is rated for 10-12 AWG wire, accommodating larger diameter conductors. Selection is based on the actual wire gauge in the application circuit.

Q: Do the physical dimension differences affect compatibility?

A: Physical dimension variations (thickness, width, length) are engineered to accommodate the different wire gauge specifications. These variations do not affect compatibility when the part is applied to its specified wire gauge range. Dimensions are not interchangeable between the two parts.

Q: What contact material is used in each part?

A: The TE Connectivity 32957 uses copper contact material with tin finish. The Keystone Electronics 8215 uses electrolytic copper contact material with tin finish. Both provide equivalent electrical conductivity and corrosion resistance for their respective applications.

Q: Are both parts available in bulk packaging?

A: Yes. Both the TE Connectivity 32957 and Keystone Electronics 8215 are supplied in bulk packaging. Current inventory levels are 1172 pieces for the 32957 and 2154 pieces for the 8215.
