Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 66424-8 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: Multimate III+
• Contact Type: Socket
• Wire Gauge: 26-30 AWG
• Contact Material: Brass
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Termination Method: Crimp
• Manufacturing Type: Stamped
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Non-Critical for Substitution):

• Packaging format (Cut Tape vs. Bulk)
• Base product number designation
• Inventory quantity

The identified substitute part 66428-4 maintains complete electrical and mechanical compatibility with the main part number 66424-8 through identical specification of all mandatory parameters. The primary distinction is packaging configuration, with 66428-4 supplied in Bulk format rather than Cut Tape.

Engineering Selection Recommendations

Primary Part Selection (66424-8): The TE Connectivity 66424-8 is the preferred selection for applications requiring RoHS compliance certification. This part is actively manufactured and supplied in Cut Tape packaging, suitable for automated assembly processes and controlled component dispensing. The RoHS Compliant status ensures regulatory alignment for restricted substance requirements.

Substitute Part Selection (66428-4): The TE Connectivity 66428-4 provides functional equivalence for applications where RoHS compliance is not a regulatory requirement. This part is actively manufactured and supplied in Bulk packaging, suitable for high-volume manual assembly operations or applications with less stringent compliance mandates. The Bulk packaging format accommodates larger quantity requirements without tape-and-reel constraints.

Compliance Considerations: Both parts maintain identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and regulatory compliance obligations specific to the end application. The RoHS status difference does not affect electrical performance or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can 66428-4 be used as a direct replacement for 66424-8 in all applications?

A: The 66428-4 provides complete electrical and mechanical compatibility with 66424-8 across all critical parameters including wire gauge, contact material, finish specification, and termination method. Selection should account for packaging format differences and RoHS compliance requirements specific to your application.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape (CT) packaging supplies components on continuous tape in specified quantities, suitable for automated pick-and-place assembly equipment. Bulk packaging supplies loose components in larger quantities, suitable for manual assembly or high-volume operations without tape-and-reel constraints.

Q: Are the electrical specifications identical between 66424-8 and 66428-4?

A: Yes. Both parts are specified for 26-30 AWG wire gauge, utilize identical brass contact material with 30.0µin gold finish thickness, and employ crimp termination. Electrical performance and contact resistance characteristics are equivalent.

Q: Does RoHS compliance affect the performance of 66424-8 compared to 66428-4?

A: RoHS compliance status reflects manufacturing process restrictions on hazardous substances and does not alter electrical or mechanical performance. The RoHS Compliant designation on 66424-8 indicates adherence to restricted substance regulations, while 66428-4 is marked as "Not applicable," indicating different compliance documentation status.

Q: What is the Moisture Sensitivity Level (MSL) rating and why is it important?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These contacts can be stored and handled under standard environmental conditions without special desiccant packaging or shelf-life limitations.

Q: Can these socket contacts be used with different pin contact types?

A: These socket contacts are designed for use within the Multimate III+ connector series. Compatibility with specific pin contacts is determined by series designation and connector assembly specifications, not by individual contact parameters.
