Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5-66506-9 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts belong to the AMPLIMITE HDP-20 connector series
• Contact Type: Pin configuration with identical stamped construction
• Electrical Specifications: Identical wire gauge range (20-24 AWG) and crimp termination method
• Material Composition: Brass base material with gold flash finish
• Environmental Rating: Moisture Sensitivity Level 1 (Unlimited) for both parts
• Regulatory Classification: Both parts share the same ECCN (EAR99) and HTSUS code

The substitute part 1658539-4 maintains full functional and mechanical compatibility with the original 5-66506-9 while offering the advantage of active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1658539-4 is the direct equivalent for the obsolete 5-66506-9 based on identical electrical and mechanical specifications within the AMPLIMITE HDP-20 series. Selection of 1658539-4 provides the following advantages:
