TE Connectivity AMP Connectors 66682-9 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 66682-9 is a pin contact for the AMPLIMITE HDP-20 connector series, designed for crimp termination of 24-28 AWG wire gauges. This stamped brass contact with gold finish is part of the AMPLIMITE HDP-20 product line and carries an obsolete product status. Due to its obsolescence, equivalent and substitute parts from the same manufacturer series are available to maintain design compatibility and ensure continued supply chain access for applications requiring this contact type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66682-9 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Series: AMPLIMITE HDP-20
• Pin or Socket: Pin
• Contact Termination: Crimp
• Wire Gauge: 24-28 AWG
• Contact Material: Brass
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain identical electrical and mechanical specifications across these parameters. Substitutes differ in product status (active versus obsolete) and regulatory compliance certifications, which do not affect functional interchangeability within the AMPLIMITE HDP-20 connector system.

Parameter Comparison

Engineering Selection Recommendations

5066682-9 (Direct Substitute): This part is the primary equivalent for the obsolete 66682-9. It maintains identical electrical and mechanical specifications and is currently in active production status. The 5066682-9 carries ROHS3 compliance certification, providing enhanced regulatory alignment for new designs and applications subject to RoHS requirements. This part is available in Cut Tape packaging and represents the recommended replacement for supply chain continuity.

66682-2 (Similar Substitute): This part provides functional equivalence to the 66682-9 with identical contact specifications and is also in active production. The 66682-2 carries RoHS compliance certification and is available in Cut Tape packaging. This part serves as an alternative substitute when 5066682-9 availability is constrained.

Both substitute parts are suitable for direct replacement in AMPLIMITE HDP-20 connector assemblies where the 66682-9 was originally specified, provided that the application does not impose additional constraints beyond the electrical and mechanical parameters listed.

Frequently Asked Questions (FAQ)

Q: Can the 5066682-9 be used as a direct replacement for the obsolete 66682-9?

A: Yes. The 5066682-9 maintains identical specifications for wire gauge (24-28 AWG), contact material (brass), contact finish (gold at 30.0µin thickness), termination method (crimp), and all other electrical and mechanical parameters. Both parts are designed for the AMPLIMITE HDP-20 connector series and are functionally interchangeable.

Q: What is the difference between the 5066682-9 and 66682-2?

A: Both parts are functionally equivalent to the 66682-9 and to each other. The primary differences are in base product number designation (5066682 versus 66682) and RoHS certification level (ROHS3 versus RoHS). Both are active production parts available in Cut Tape packaging. Selection between them depends on supply availability and specific regulatory requirements of the application.

Q: Why is the 66682-9 marked as obsolete?

A: The 66682-9 has been superseded by the 5066682-9 and 66682-2 in the manufacturer's product line. The substitute parts offer improved regulatory compliance (RoHS certification) while maintaining identical functional specifications. Obsolescence does not affect the technical performance of existing 66682-9 inventory but indicates that new designs should specify the active production equivalents.

Q: Are there packaging differences between the main part and substitutes?

A: The 66682-9 packaging specification is not provided in the technical data. Both substitute parts (5066682-9 and 66682-2) are available in Cut Tape (CT) packaging. Packaging format does not affect the electrical or mechanical compatibility of the contact itself within the AMPLIMITE HDP-20 connector system.

Q: Can these contacts be used with wire gauges outside the 24-28 AWG range?

A: No. All three parts are specified exclusively for 24-28 AWG wire gauges. Use with wire gauges outside this range will result in improper crimp termination and connection reliability issues.

Q: What is the significance of the MSL rating of 1 (Unlimited)?

A: Moisture Sensitivity Level 1 indicates that these contacts have unlimited shelf life and do not require special moisture-controlled storage or handling procedures. This applies to all three parts and simplifies inventory management and logistics.
