Engineering Selection Recommendations
The DF1EC-6P-2.5DSA(35) is the appropriate selection for new designs and component replacement applications. The substitute part maintains identical electrical and mechanical specifications to the original DF1EC-6P-2.5DSA(73), ensuring functional compatibility in existing circuit designs.
The DF1EC-6P-2.5DSA(35) carries active product status with ROHS3 compliance and MSL 1 rating, providing superior supply chain availability and regulatory alignment compared to the obsolete original part. Both parts share identical contact configurations, pitch spacing, mounting methodology, and thermal operating ranges, eliminating the need for PCB redesign or connector interface modifications.
Frequently Asked Questions (FAQ)
Q: Can DF1EC-6P-2.5DSA(35) be used as a direct replacement for DF1EC-6P-2.5DSA(73)?
A: Yes. Both parts share identical connector type, position count, pitch spacing, contact configuration, mounting type, and termination method. No circuit modifications or PCB layout changes are required.
Q: What is the difference between the two part numbers?
A: The primary difference is product status. DF1EC-6P-2.5DSA(73) is obsolete, while DF1EC-6P-2.5DSA(35) is active. The suffix designation (73 vs. 35) indicates different manufacturing or packaging variants, but electrical and mechanical specifications remain identical.
Q: Are there any compliance differences between these parts?
A: DF1EC-6P-2.5DSA(35) is certified ROHS3 compliant with MSL 1 rating. The original part does not specify these certifications. For applications requiring regulatory compliance documentation, the substitute part provides explicit certification.
Q: What is the mating pitch specification?
A: Both parts operate at 0.098" (2.50mm) pitch spacing. This specification is critical for connector compatibility and cannot be altered through substitution.
Q: Are the contact materials identical?
A: Yes. Both parts use brass contacts with tin plating at 39.4µin (1.00µm) thickness on mating surfaces, ensuring equivalent electrical performance and corrosion resistance.
Q: What is the current rating for this connector?
A: Both parts are rated for 3A per contact at the specified operating temperature range of -35°C to 85°C.
