Engineering Selection Recommendations

A3C-16DA-2DSA(71) is the primary substitute for the obsolete A3C-16DA-2DSA. Both parts are from the same manufacturer and series, with identical electrical and mechanical specifications. The key advantage is that A3C-16DA-2DSA(71) holds active product status and is ROHS3 compliant, addressing regulatory requirements that the original part does not meet. This part is available in tube packaging with 1444 units in stock.

SMM-108-01-S-D from Samtec Inc. is an alternative substitute that meets all mandatory compatibility parameters. This part offers enhanced performance characteristics including higher current rating (3.2A per contact versus 1A), higher voltage rating (350VAC versus 200VAC), and extended operating temperature range (-55°C to 125°C versus -55°C to 85°C). The SMM-108-01-S-D uses Liquid Crystal Polymer insulation and Beryllium Copper contacts, providing superior thermal and mechanical properties. This part is also ROHS3 compliant and available in tube packaging with 1110 units in stock.

Both substitutes are suitable for direct replacement in applications where the original A3C-16DA-2DSA was specified, with the choice between them depending on performance requirements and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can A3C-16DA-2DSA(71) be used as a direct replacement for A3C-16DA-2DSA?

A: Yes. Both parts share identical connector type, contact configuration, pitch, mounting method, and termination. The primary difference is product status and compliance certification. A3C-16DA-2DSA(71) is active and ROHS3 compliant, making it the recommended substitute for the obsolete original part.

Q: What are the key differences between A3C-16DA-2DSA(71) and SMM-108-01-S-D?

A: Both parts maintain identical mating pitch (0.079"), position count (16), row configuration (2 rows), and fastening method (push-pull). Differences include manufacturer (Hirose versus Samtec), insulation material (PBT versus LCP), contact material (Phosphor Bronze versus Beryllium Copper), and performance ratings. SMM-108-01-S-D provides higher current capacity (3.2A versus 1A), higher voltage rating (350VAC versus 200VAC), and wider operating temperature range (-55°C to 125°C versus -55°C to 85°C).

Q: Are there mechanical compatibility concerns when substituting SMM-108-01-S-D for A3C-16DA-2DSA?

A: Mechanical compatibility is maintained for mating and mounting. The SMM-108-01-S-D has slightly different insulation height (0.140" versus 0.165") and contact length (0.120" versus 0.118"), which remain within acceptable tolerance for board-to-board and cable applications. Verify specific PCB layout requirements for your application.

Q: What is the packaging difference between the substitutes?

A: Both A3C-16DA-2DSA(71) and SMM-108-01-S-D are supplied in tube packaging. The original A3C-16DA-2DSA packaging specification was not provided in the available data.

Q: Do both substitutes meet current compliance requirements?

A: Yes. Both A3C-16DA-2DSA(71) and SMM-108-01-S-D are ROHS3 compliant and REACH unaffected. The original A3C-16DA-2DSA is RoHS non-compliant, making substitution necessary for applications requiring regulatory compliance.
