Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-66683-0 is determined by strict adherence to the following parameters:

Primary Compatibility Criteria:

• Series designation: AMPLIMITE HDP-20
• Contact configuration: Socket
• Wire gauge range: 24-28 AWG
• Termination type: Crimp
• Contact finish: Gold
• Moisture sensitivity level: 1 (Unlimited)
• Stamping classification: Stamped

Secondary Considerations:

• Contact material (Phosphor Bronze or Brass acceptable)
• Contact finish thickness (30.0µin or Flash acceptable)
• Packaging format (Tape & Reel or Cut Tape)
• Product status (Active preferred over Obsolete)
• RoHS compliance (ROHS3 Compliant preferred)

All three substitute parts meet the primary compatibility criteria and maintain functional equivalence within the AMPLIMITE HDP-20 connector system.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 66683-2

The 66683-2 is the optimal substitute for the 1-66683-0. This part maintains identical contact material (Phosphor Bronze), contact finish thickness (30.0µin), and all primary compatibility parameters. The 66683-2 carries Active product status and ROHS3 compliance, eliminating obsolescence and regulatory concerns. Cut Tape packaging is suitable for standard component handling and assembly processes.

Secondary Recommendation: 1-5066683-0

The 1-5066683-0 provides direct functional equivalence with Active status and ROHS3 compliance. The contact material differs (Brass instead of Phosphor Bronze), but this substitution remains valid within the AMPLIMITE HDP-20 series specifications. Tape & Reel packaging accommodates automated assembly environments. This part is appropriate when production processes require reel-based component feeding.

Tertiary Recommendation: 5066683-7

The 5066683-7 is functionally equivalent with Active status and ROHS3 compliance. Contact material is Brass, and contact finish thickness is specified as Flash rather than 30.0µin. Tape & Reel packaging supports automated assembly. This part is suitable for applications where flash gold plating meets electrical performance requirements.

All three substitutes eliminate the obsolescence status of the original 1-66683-0 and provide ROHS3 compliance for current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1-5066683-0 replace the 1-66683-0 in existing AMPLIMITE HDP-20 assemblies?

A: Yes. Both parts are socket contacts for the AMPLIMITE HDP-20 series with identical wire gauge (24-28 AWG), termination method (Crimp), and contact finish (Gold). The contact material differs (Brass vs. Phosphor Bronze), but both materials are acceptable within the series specification. The 1-5066683-0 is Active and ROHS3 compliant, addressing the obsolescence of the original part.

Q: What is the difference between the 66683-2 and 1-5066683-0?

A: The 66683-2 uses Phosphor Bronze contacts with 30.0µin gold plating and Cut Tape packaging. The 1-5066683-0 uses Brass contacts with 30.0µin gold plating and Tape & Reel packaging. Both are Active, ROHS3 compliant, and functionally equivalent within the AMPLIMITE HDP-20 series. Selection depends on packaging requirements: Cut Tape for manual or small-batch assembly, Tape & Reel for automated production.

Q: Is the 5066683-7 suitable as a direct substitute?

A: Yes. The 5066683-7 maintains all primary compatibility parameters: AMPLIMITE HDP-20 series, socket contact, 24-28 AWG wire gauge, crimp termination, and gold finish. The contact material is Brass, and the finish thickness is Flash rather than 30.0µin. Both specifications are acceptable within the series. The part is Active and ROHS3 compliant.

Q: Why is the 1-66683-0 classified as Obsolete?

A: The 1-66683-0 is no longer in active production. The substitute parts (66683-2, 1-5066683-0, and 5066683-7) are all Active and provide equivalent functionality. Migration to an active part number ensures long-term supply availability and compliance with current regulatory standards.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk, Cut Tape, or Tape & Reel) does not affect electrical or mechanical performance. Selection is based on assembly process requirements. Cut Tape and Tape & Reel formats support different production methodologies but deliver identical contact performance.

Q: Are all substitutes RoHS compliant?

A: The 1-66683-0 is RoHS non-compliant. All three substitute parts (66683-2, 1-5066683-0, and 5066683-7) are ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Q: What is the significance of contact finish thickness differences?

A: The 1-66683-0, 66683-2, and 1-5066683-0 specify 30.0µin (0.76µm) gold plating. The 5066683-7 specifies Flash gold plating. Both thicknesses provide adequate corrosion resistance and electrical conductivity within the AMPLIMITE HDP-20 series. Selection depends on specific application requirements and environmental exposure conditions.
