TE Connectivity 66683-7 Socket Contact Equivalent & Substitute Parts

Part Overview

The TE Connectivity 66683-7 is a socket contact designed for the AMPLIMITE HDP-20 connector series. This component is a stamped phosphor bronze socket contact with gold plating, rated for 24-28 AWG wire gauges and terminated via crimp connection. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and assembly operations. Substitute parts must maintain electrical and mechanical compatibility within the AMPLIMITE HDP-20 series while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66683-7 is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

• Connector series designation (AMPLIMITE HDP-20)
• Contact configuration (Socket type)
• Wire gauge range (24-28 AWG)
• Termination method (Crimp)
• Contact finish specification (Gold)
• Stamping classification (Stamped)
• Moisture sensitivity rating (MSL 1)

Secondary Considerations:

• Product status (Active vs. Obsolete)
• RoHS compliance certification
• Contact material composition
• Packaging format availability
• Inventory availability

The identified substitutes maintain all primary compatibility criteria. Variations in contact material (phosphor bronze versus brass) and contact finish thickness (flash versus 30.0µin) do not affect functional interchangeability within the AMPLIMITE HDP-20 series, as both specifications satisfy the electrical and mechanical requirements for this contact category.

Parameter Comparison

Engineering Selection Recommendations

66683-2 (Primary Substitute)

The 66683-2 is the recommended primary substitute for the obsolete 66683-7. This part maintains identical electrical and mechanical specifications within the AMPLIMITE HDP-20 series and carries active product status. The 66683-2 is ROHS3 compliant, addressing regulatory requirements that the original part does not satisfy. The contact finish thickness specification of 30.0µin (0.76µm) provides enhanced durability compared to the flash finish of the original part. Packaging in Cut Tape format supports standard assembly line integration. Inventory availability of 42,403 pieces ensures supply continuity for production requirements.

5066683-7 (Secondary Substitute)

The 5066683-7 serves as an alternative substitute with active product status and ROHS3 compliance. This part differs from the main part in contact material composition (brass versus phosphor bronze) and base product number designation. The brass contact material maintains functional compatibility within the AMPLIMITE HDP-20 series for the specified wire gauge and termination requirements. Packaging in Tape & Reel format accommodates automated assembly processes. Inventory availability of 1,125 pieces supports moderate-volume procurement. Selection of this substitute is appropriate when Tape & Reel packaging is required or when phosphor bronze material is not specified in design documentation.

Both substitutes satisfy all primary compatibility criteria and provide compliance advantages over the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can 66683-2 and 5066683-7 be used interchangeably with 66683-7?

A: Both parts are functionally compatible within the AMPLIMITE HDP-20 connector series for applications requiring 24-28 AWG socket contacts with crimp termination and gold finish. Interchangeability is confirmed by matching wire gauge, contact type, termination method, connector series, and MSL rating. Contact material differences (phosphor bronze versus brass) do not affect functional performance in this application category.

Q: What is the significance of the contact finish thickness difference between 66683-7 and 66683-2?

A: The 66683-7 specifies flash gold plating, while 66683-2 specifies 30.0µin (0.76µm) thickness. Both finishes provide electrical conductivity and corrosion resistance required for the AMPLIMITE HDP-20 series. The thicker finish on 66683-2 offers extended durability under repeated mating cycles and environmental exposure.

Q: Why is 66683-7 classified as obsolete?

A: The 66683-7 is obsolete and no longer in active production. Active substitutes 66683-2 and 5066683-7 are available for all new designs and ongoing procurement requirements.

Q: Does packaging format affect electrical or mechanical compatibility?

A: Packaging format (Cut Tape versus Tape & Reel) does not affect electrical or mechanical compatibility. Packaging selection is determined by assembly process requirements and handling procedures. Cut Tape format (66683-2) supports manual and semi-automated assembly. Tape & Reel format (5066683-7) is optimized for fully automated pick-and-place assembly systems.

Q: Are both substitutes RoHS compliant?

A: Yes. Both 66683-2 and 5066683-7 are ROHS3 compliant. The original 66683-7 is RoHS non-compliant. Selection of either substitute addresses RoHS compliance requirements for new designs and regulated markets.

Q: What is the difference between the base product numbers 66683 and 5066683?

A: The base product number designates the product family and manufacturing specification. Both base numbers reference socket contacts within the AMPLIMITE HDP-20 series with identical functional specifications for this application. The different base numbers reflect distinct manufacturing or specification revisions within the TE Connectivity product line.

Q: Can I use 5066683-7 if my assembly process requires Cut Tape packaging?

A: No. The 5066683-7 is supplied exclusively in Tape & Reel format. For Cut Tape packaging requirements, use 66683-2.

Q: Is inventory availability a factor in substitution eligibility?

A: Inventory availability does not determine substitution eligibility. Both 66683-2 and 5066683-7 are qualified substitutes based on electrical and mechanical parameters. Inventory levels are provided for procurement planning purposes only.
