Frequently Asked Questions (FAQ)

Q: Can 1658537-1 be used as a direct replacement for 5-66504-6 in existing connector assemblies?

A: Yes. Both parts are socket contacts for the AMPLIMITE HDP-20 series with identical wire gauge ratings (20-24 AWG), termination method (crimp), contact material (phosphor bronze), and finish specifications (gold flash). They are functionally and mechanically interchangeable.

Q: What is the primary reason for substituting the obsolete 5-66504-6?

A: The 5-66504-6 is classified as obsolete and no longer in active production. The 1658537-1 is an active product with current manufacturing support and confirmed inventory availability, ensuring reliable supply for new designs and repair applications.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The 1658537-1 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions applicable to electronic components in most regulated markets. The obsolete 5-66504-6 carries no RoHS classification.

Q: Are there packaging differences between the two parts?

A: The main part packaging is not specified in available documentation. The substitute part 1658537-1 is supplied in Cut Tape (CT) format, which is a standard packaging method for automated assembly and component distribution.

Q: What wire gauges are supported by both parts?

A: Both the 5-66504-6 and 1658537-1 support 20-24 AWG wire gauges. This rating applies to the crimp termination specification and must be observed during assembly.

Q: Are both parts suitable for unlimited moisture exposure?

A: Yes. Both parts carry Moisture Sensitivity Level (MSL) 1 classification, indicating unlimited moisture tolerance with no special storage or handling requirements.

Q: Can these parts be used interchangeably in new product designs?

A: Yes. The 1658537-1 is the recommended choice for new designs due to its active product status, ROHS3 compliance, and confirmed supply availability. The obsolete 5-66504-6 should not be specified for new applications.
