Engineering Selection Recommendations
The DF3-8S-2DSA(25) is the qualified substitute for the obsolete DF3-8S-2DSA(20). Both parts are electrically and mechanically equivalent across all functional parameters. The primary distinction is product status and regulatory compliance: the DF3-8S-2DSA(25) is active in production and RoHS compliant, whereas the DF3-8S-2DSA(20) is obsolete and RoHS non-compliant. For new designs or ongoing procurement, the DF3-8S-2DSA(25) is the appropriate selection. Existing assemblies using the DF3-8S-2DSA(20) can be retrofitted with the DF3-8S-2DSA(25) without functional impact.
Frequently Asked Questions (FAQ)
Q: Can the DF3-8S-2DSA(25) be used as a direct replacement for the DF3-8S-2DSA(20)?
A: Yes. Both connectors share identical electrical ratings (3A, 30VAC), mechanical dimensions (8 positions, 0.079" pitch, through-hole mounting), contact configuration (female socket, tin-plated), and operating temperature range (-30°C to 85°C). They are functionally interchangeable.
Q: What is the difference between these two part numbers?
A: The DF3-8S-2DSA(20) is obsolete and RoHS non-compliant. The DF3-8S-2DSA(25) is currently active in production and RoHS compliant. The packaging differs: the DF3-8S-2DSA(20) has no specified packaging, while the DF3-8S-2DSA(25) is supplied in tube packaging.
Q: Are there any compatibility concerns when substituting the DF3-8S-2DSA(25) for the DF3-8S-2DSA(20)?
A: No compatibility concerns exist. The connectors are mechanically and electrically identical. PCB footprints, mating interfaces, and electrical performance remain unchanged.
Q: What is the availability status of these parts?
A: The DF3-8S-2DSA(20) is obsolete with 756 pieces in stock. The DF3-8S-2DSA(25) is active with 1189 pieces in stock.
