Parameter Comparison

Engineering Selection Recommendations

The A3C-8DA-2DSA(71) is the direct equivalent for the obsolete A3C-8DA-2DSA. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in all applications. The primary distinction is product status: the original part is obsolete, while the A3C-8DA-2DSA(71) is active and currently in production.

The substitute part offers improved regulatory compliance, meeting ROHS3 requirements compared to the non-compliant status of the original. Both parts maintain REACH unaffected status and identical ECCN and HTSUS classifications. The A3C-8DA-2DSA(71) is available in tray packaging with higher inventory levels (1406 pieces) compared to the original part (831 pieces).

For new designs or system replacements, the A3C-8DA-2DSA(71) is the appropriate selection. For legacy system maintenance requiring the original part specification, the A3C-8DA-2DSA(71) provides full electrical and mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Are the A3C-8DA-2DSA and A3C-8DA-2DSA(71) physically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing (0.079"), row configuration, mounting type (through-hole), and contact geometry. They are direct physical substitutes.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The A3C-8DA-2DSA is obsolete and RoHS non-compliant. The A3C-8DA-2DSA(71) is active production and ROHS3 compliant. All electrical and mechanical parameters are identical.

Q: Can I use the A3C-8DA-2DSA(71) in applications originally designed for the A3C-8DA-2DSA?

A: Yes. The substitute part meets all electrical ratings (1A, 200VAC), temperature range (-55°C ~ 85°C), and mechanical specifications of the original. The improved RoHS3 compliance provides additional regulatory alignment.

Q: What packaging is available for the substitute part?

A: The A3C-8DA-2DSA(71) is supplied in tray packaging, differing from the original part's packaging specification.

Q: Are there any compatibility concerns with PCB layouts or mating connectors?

A: No. Identical pitch spacing (0.079"), row spacing (0.079"), contact geometry, and stacking heights (5.1mm, 6mm) ensure full compatibility with existing PCB layouts and mating connector designs.

Q: What is the current availability of these parts?

A: The A3C-8DA-2DSA(71) is in active production with 1406 pieces in stock. The original A3C-8DA-2DSA is obsolete with limited remaining inventory (831 pieces).
