Engineering Selection Recommendations
The DF3-10S-2DSA(25) is the direct substitute for the obsolete DF3-10S-2DSA(20). Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.
The DF3-10S-2DSA(25) offers the additional advantage of ROHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations. The substitute part is currently in active production status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete original part.
Frequently Asked Questions (FAQ)
Q: Are the DF3-10S-2DSA(20) and DF3-10S-2DSA(25) electrically and mechanically interchangeable?
A: Yes. Both parts maintain identical specifications for connector type, contact configuration, pitch spacing, current rating, voltage rating, operating temperature range, and contact materials. They are direct functional equivalents.
Q: What is the significance of the different part number suffixes (20 vs. 25)?
A: The suffix designates packaging configuration. The DF3-10S-2DSA(20) uses standard packaging, while the DF3-10S-2DSA(25) is supplied in tube packaging. The electrical and mechanical specifications remain unchanged.
Q: Why is RoHS compliance status different between these parts?
A: The DF3-10S-2DSA(20) is RoHS non-compliant, while the DF3-10S-2DSA(25) is ROHS3 compliant. For applications requiring RoHS compliance, the DF3-10S-2DSA(25) is the appropriate selection.
Q: Can I use the DF3-10S-2DSA(25) as a replacement in existing designs using the DF3-10S-2DSA(20)?
A: Yes. The substitute part maintains all critical electrical and mechanical parameters. PCB footprints, mating connector specifications, and electrical performance remain identical.
Q: What is the current availability status of these parts?
A: The DF3-10S-2DSA(20) is obsolete. The DF3-10S-2DSA(25) is active production with 1388 units in stock.
