Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5-66505-7 is determined by strict alignment with the following parameters: connector series (AMPLIMITE HDP-20), contact configuration (socket), wire gauge range (24-28 AWG), contact material (phosphor bronze), contact finish (gold flash), termination method (crimp), and manufacturing process (stamped). All identified substitutes maintain these core electrical and mechanical specifications, ensuring functional compatibility within the AMPLIMITE HDP-20 connector system.

The primary distinction between the main part and substitutes is product status and regulatory compliance. The 5-66505-7 is obsolete and RoHS non-compliant, while active substitutes meet current regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both 1658538-3 and 66505-4 are functionally equivalent to the 5-66505-7 across all critical electrical and mechanical parameters. Selection between these substitutes should be based on the following factors:

1658538-3 (Direct Substitute): This part carries ROHS3 compliance certification and represents the primary recommended substitute. It maintains the highest inventory availability at 47,038 pieces and is supplied in Cut Tape packaging. This part is suitable for new production designs and applications requiring the highest level of regulatory compliance.

66505-4 (Similar Substitute): This part maintains RoHS compliance and shares the same base product number (66505) as the original part, indicating direct lineage within the product family. With 12,170 pieces in inventory and Cut Tape packaging, this part is suitable for applications where design continuity with the original part number family is preferred.

Both substitutes are active products with unlimited moisture sensitivity rating and identical electrical specifications. Selection should prioritize 1658538-3 for new designs and 66505-4 for legacy system maintenance where product family continuity is a consideration.

Frequently Asked Questions (FAQ)

Q: Can 1658538-3 and 66505-4 be used interchangeably with 5-66505-7?

A: Yes. Both substitutes maintain identical wire gauge (24-28 AWG), contact material (phosphor bronze), contact finish (gold flash), termination method (crimp), and series compatibility (AMPLIMITE HDP-20). They are functionally equivalent for all applications where the original part was specified.

Q: What is the difference between the two substitute parts?

A: The primary differences are regulatory compliance level (1658538-3 is ROHS3 compliant; 66505-4 is RoHS compliant), base product number lineage (66505-4 shares the same base number as the original part), and inventory availability (1658538-3 has higher stock levels). Both are electrically and mechanically identical.

Q: Why is the original part 5-66505-7 obsolete?

A: The part is classified as obsolete due to its RoHS non-compliance status. Current manufacturing and supply standards require RoHS-compliant alternatives. Both substitute parts meet modern regulatory requirements.

Q: Does packaging affect compatibility?

A: Packaging (Cut Tape) affects handling, storage, and ordering logistics but does not affect electrical or mechanical compatibility. Both substitutes are supplied in Cut Tape packaging, which is standard for connector contact components.

Q: Are there any compliance differences I should consider?

A: 1658538-3 carries ROHS3 compliance, representing the most current regulatory standard. 66505-4 carries RoHS compliance. For new production designs, 1658538-3 is recommended. Both parts meet current industry standards for new applications.

Q: Can I mix these parts in the same connector assembly?

A: Yes. All three parts (original and both substitutes) are mechanically and electrically identical within the AMPLIMITE HDP-20 series. They can be used together in the same assembly without functional impact.

Q: What is the moisture sensitivity level, and why does it matter?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These contacts can be stored and handled under standard conditions without special moisture control requirements.
