Engineering Selection Recommendations

The Hirose HIF3FB-64PA-2.54DSA(71) is an active product suitable for applications where the 3M N2564-6002-UG is no longer available. Selection of this substitute requires evaluation of three specific constraints:

Temperature Derating: Applications operating above 85°C require confirmation that system performance remains acceptable within the reduced upper temperature limit of 85°C versus the original 105°C specification.

Current Capacity: The Hirose part is rated for 1A per contact versus 1.75A for the 3M part. Circuit designs operating at or near 1.75A per contact require current redistribution analysis or alternative component selection.

RoHS Compliance: The Hirose part meets RoHS requirements, while the 3M part does not. This difference is relevant for applications subject to RoHS regulatory requirements or customer specifications.

All other critical parameters—connector geometry, pitch, shrouding, fastening mechanism, and contact finish material—are equivalent between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the Hirose HIF3FB-64PA-2.54DSA(71) be used as a direct replacement for the 3M N2564-6002-UG?

A: Physical and electrical compatibility exists for the mating interface. However, the reduced current rating (1A vs. 1.75A) and lower maximum operating temperature (85°C vs. 105°C) must be evaluated against application requirements before substitution.

Q: What is the impact of the different contact finish thicknesses?

A: The 3M part specifies 15.0µin gold plating on mating contacts; the Hirose part specifies 8.00µin. Both thicknesses provide corrosion resistance and electrical conductivity. The thinner Hirose plating may result in slightly different contact wear characteristics over extended mating cycles.

Q: Are the post finishes compatible?

A: The 3M part uses Tin-Lead post finish; the Hirose part uses Tin. Both are suitable for solder termination. The Tin-Lead finish in the 3M part is no longer compliant with RoHS regulations, whereas the Tin finish in the Hirose part is RoHS-compliant.

Q: Does the difference in insulation material affect performance?

A: The 3M part uses glass-filled PCT/Polyester; the Hirose part uses PBT. Both materials meet UL94 V-0 flammability requirements and provide adequate insulation for the specified voltage and current ratings. Material selection may affect mechanical properties and thermal characteristics in specific environments.

Q: What packaging format is supplied for the Hirose substitute?

A: The Hirose HIF3FB-64PA-2.54DSA(71) is supplied in Tray packaging, whereas the 3M part packaging format is not specified in available documentation.
