Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 6-66506-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: AMPLIMITE HDP-20
• Pin or Socket: Pin
• Contact Termination: Crimp
• Wire Gauge: 20-24 AWG
• Contact Material: Brass
• Contact Finish: Gold
• Type: Stamped
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 1658539-5 maintains full compatibility across all functional and mechanical parameters. The primary distinction is product status (active versus obsolete) and compliance certifications, which determine long-term availability and regulatory suitability.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement: Part 1658539-5 is the appropriate selection for applications requiring AMPLIMITE HDP-20 series pin contacts with 20-24 AWG crimp termination. This part is active in production, ensuring long-term availability and supply chain stability. The ROHS3 compliance status of 1658539-5 aligns with current regulatory requirements in most jurisdictions.

For Legacy System Maintenance: The obsolete 6-66506-2 may remain in use for existing assemblies where component replacement is not required. However, for any new procurement or system redesign, 1658539-5 provides functional equivalence with improved compliance status.

Compliance Considerations: The transition from RoHS non-compliant (6-66506-2) to ROHS3 compliant (1658539-5) represents a regulatory advancement. Applications subject to RoHS directives should prioritize 1658539-5 for new implementations.

Frequently Asked Questions (FAQ)

Q: Are 6-66506-2 and 1658539-5 mechanically interchangeable? A: Yes. Both parts are stamped pin contacts for the AMPLIMITE HDP-20 series with identical wire gauge (20-24 AWG), termination method (crimp), and contact material (brass with gold finish). They are mechanically and electrically interchangeable within the connector system.

Q: What is the difference in contact finish thickness between these parts? A: The 6-66506-2 specifies 1.18µin (0.030µm) gold plating thickness, while 1658539-5 uses a flash gold finish. Both finishes provide corrosion resistance and conductivity suitable for the AMPLIMITE HDP-20 series application range.

Q: Why is 6-66506-2 classified as obsolete? A: Obsolete status indicates the part is no longer in active production. The manufacturer has transitioned to 1658539-5 as the current production equivalent, which maintains full functional compatibility while offering improved compliance certifications.

Q: Does packaging affect substitution compatibility? A: Packaging format (Cut Tape for 1658539-5) does not affect electrical or mechanical compatibility. Packaging selection depends on assembly process requirements and inventory management practices. The functional contact specifications remain identical regardless of packaging format.

Q: Is 1658539-5 suitable for applications originally designed for 6-66506-2? A: Yes. The substitute part maintains all critical parameters: series compatibility, pin configuration, wire gauge range, termination method, and contact material. Applications designed for 6-66506-2 operate identically with 1658539-5.

Q: What is the significance of ROHS3 compliance on 1658539-5? A: ROHS3 compliance indicates the part meets current Restriction of Hazardous Substances directives. This certification is required for products sold in the European Union and many other regulated markets. The non-compliant status of 6-66506-2 may restrict its use in new designs subject to these regulations.
