Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 65-54748 is based on electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters: Wire gauge specification (20 AWG) determines current-carrying capacity and mating interface geometry. Contact material (copper alloy) and finish (gold) establish electrical conductivity and corrosion resistance characteristics.

Mechanical Parameters: Socket contact type, crimp termination method, and machined construction ensure physical compatibility with mating pin contacts and assembly processes.

Compliance Parameters: ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1) establish regulatory and environmental performance requirements.

The substitute part AT62-210-1231-1820 maintains equivalence across all specified parameters while transitioning from the obsolete ATPSeries™ to the active ASeries™ product line.

Parameter Comparison

Engineering Selection Recommendations

The AT62-210-1231-1820 contact serves as the direct functional equivalent for the obsolete 65-54748. Selection of this substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status, ensuring ongoing availability, manufacturing support, and supply chain continuity. The obsolete status of 65-54748 eliminates long-term procurement viability.

Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component applications. Moisture sensitivity level equivalence (MSL 1) confirms environmental performance parity.

Electrical and Mechanical Equivalence: Identical specifications across wire gauge, contact type, termination method, material composition, and finish ensure direct functional substitution without circuit redesign or assembly process modification.

Series Transition: Migration from ATPSeries™ to ASeries™ represents a product line evolution within the Amphenol Sine Systems Corp portfolio while maintaining DiagnosticGrade™ classification and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can AT62-210-1231-1820 be used as a direct replacement for 65-54748 in existing assemblies?

A: Yes. The substitute part maintains identical electrical and mechanical specifications across all critical parameters including wire gauge, contact type, termination method, material, and finish. No assembly process modification is required.

Q: What is the difference between the ATPSeries™ and ASeries™ product lines?

A: Both series are manufactured by Amphenol Sine Systems Corp and maintain equivalent performance specifications for the 20 AWG socket contact application. The ASeries™ represents the current active product line, while ATPSeries™ is obsolete. The substitute part retains DiagnosticGrade™ classification in both series.

Q: Are there packaging differences between these parts?

A: The 65-54748 packaging specification is not provided in the technical data. The AT62-210-1231-1820 is supplied in bulk packaging. Packaging configuration should be verified against specific assembly requirements.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for electronic component applications.

Q: What is the moisture sensitivity level, and does it affect storage or handling?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture control requirements. Standard component storage practices apply.

Q: Is the gold finish specification identical between both parts?

A: Yes. Both parts specify gold contact finish. Contact finish thickness is not provided in the technical specifications for either part.
