TE Connectivity AMP Connectors 32981 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 32981 is an insulated spade terminal connector designed for crimp termination of 16-22 AWG wire. This red 8 stud terminal is part of the Plasti-Grip series and is classified as an active product. The connector features a tin-plated copper contact with serrated termination and is suitable for free-hanging, in-line mounting applications. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific certifications necessitate alternative sourcing while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TE Connectivity 32981 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Stud/Tab Size: 8 Stud (electrical interface requirement)
• Termination Type: Crimp (assembly process compatibility)
• Contact Material: Copper (electrical conductivity requirement)
• Contact Finish: Tin (corrosion resistance and solderability)
• Color: Red (circuit identification standard)
• Mounting Type: Free Hanging (In-Line) (mechanical installation requirement)
• Terminal Type: Standard (functional classification)

Secondary Compatibility Criteria:

• Wire Gauge Range: Overlap within 16-22 AWG specification
• Insulation Type: Insulated (safety and isolation requirement)

The Keystone Electronics 8228 qualifies as a substitute part. While the wire gauge range is narrower (18-22 AWG versus 16-22 AWG), the upper range overlap of 18-22 AWG provides functional compatibility for applications within this shared specification. All primary compatibility criteria are met.

Engineering Selection Recommendations

TE Connectivity 32981 Selection Criteria:

• Applications requiring 16-22 AWG wire gauge compatibility across the full range
• Designs where the wider outer edge dimension (0.375") is specified
• Applications where RoHS compliance status is not a design requirement
• Designs utilizing the Plasti-Grip series specification

Keystone Electronics 8228 Selection Criteria:

• Applications limited to 18-22 AWG wire gauge range
• Designs where ROHS3 compliance is required
• Designs where REACH compliance documentation is required
• Applications where the narrower outer edge dimension (0.300") is acceptable
• Designs where dimensional variation does not impact mechanical fit

Both parts maintain active product status and share identical electrical interface characteristics (8 stud, tin-plated copper contact, crimp termination). Selection between these parts is determined by wire gauge requirements, regulatory compliance mandates, and mechanical dimensional constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the Keystone Electronics 8228 be used in place of the TE Connectivity 32981 in all applications?

A: The Keystone Electronics 8228 is compatible with applications using 18-22 AWG wire. Applications requiring 16-17 AWG wire must use the TE Connectivity 32981, as the substitute part does not support this lower gauge range.

Q: What is the significance of the dimensional differences between these parts?

A: The TE Connectivity 32981 has a wider outer edge dimension (0.375" versus 0.300") and greater overall length (0.920" versus 0.850"). These dimensional variations may affect mechanical fit within connector housings or terminal blocks. Verify that the receiving component accommodates the selected terminal dimensions.

Q: Are there differences in insulation material between these parts?

A: The TE Connectivity 32981 uses Poly-Vinyl Chloride (PVC) insulation, while the Keystone Electronics 8228 uses Vinyl insulation. Both are insulated terminals suitable for standard applications. Material selection may impact performance in specific environmental conditions.

Q: What does the serrated termination feature on the TE Connectivity 32981 provide?

A: The serrated termination on the TE Connectivity 32981 enhances mechanical grip and electrical contact consistency during the crimp process. The Keystone Electronics 8228 does not list this feature in the provided specifications.

Q: How do the RoHS and REACH compliance statuses affect part selection?

A: The Keystone Electronics 8228 is ROHS3 compliant and REACH unaffected, providing documented regulatory compliance. The TE Connectivity 32981 lists RoHS status as not applicable and REACH status as vendor undefined. Applications subject to RoHS3 or REACH regulatory requirements should specify the Keystone Electronics 8228.

Q: Are both parts suitable for the same crimp tool specifications?

A: Both parts are crimp termination connectors with 8 stud interfaces. Crimp tool compatibility depends on the specific tool manufacturer's specifications for 8 stud terminals and the wire gauge range being terminated. Consult the crimp tool documentation for the wire gauge range being used.

Q: What is the inventory status for these parts?

A: The TE Connectivity 32981 has 4140 pieces in stock. The Keystone Electronics 8228 has 2062 pieces in stock. Both are listed as new original inventory.
