Key Parameters

Substitute Part Grouping Explanation

The A3C-8DA-2DSC(71) qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Configuration: Both are 8-position receptacle connectors in the A3 series
• Electrical Specifications: Identical pitch (0.079"/2.00mm), row spacing (0.079"/2.00mm), current rating (1A), and voltage rating (200VAC)
• Mechanical Interface: Both feature through-hole solder termination with identical contact geometry and mating interface
• Contact Materials & Finish: Both utilize phosphor bronze contacts with gold plating on mating surfaces and tin plating on posts
• Environmental Ratings: Both operate across -55°C to 85°C temperature range with UL94 V-0 flammability rating
• Insulation Material: Both use Polybutylene Terephthalate (PBT) with identical insulation height (0.165"/4.20mm)

The primary distinction is product status: A3C-8DA-2DSC is obsolete, while A3C-8DA-2DSC(71) is active. The substitute maintains full electrical and mechanical compatibility with identical mating interface dimensions and contact specifications.

Parameter Comparison

Engineering Selection Recommendations

The A3C-8DA-2DSC(71) is the appropriate selection for new designs and ongoing procurement due to its active product status and ROHS3 compliance. The obsolete A3C-8DA-2DSC should be replaced with the A3C-8DA-2DSC(71) variant, which maintains identical electrical and mechanical specifications while offering current manufacturing support and regulatory compliance.

For existing systems currently using the A3C-8DA-2DSC, the A3C-8DA-2DSC(71) provides direct compatibility without requiring PCB redesign or connector interface modifications. Both parts share identical mating dimensions, contact pitch, and electrical ratings.

Frequently Asked Questions (FAQ)

Q: Are A3C-8DA-2DSC and A3C-8DA-2DSC(71) mechanically interchangeable?

A: Yes. Both connectors feature identical 0.079" (2.00mm) pitch, 2-row configuration, and through-hole mounting interface. The mating interface dimensions and contact geometry are identical, allowing direct substitution without PCB modification.

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

A: The primary differences are product status and regulatory compliance. A3C-8DA-2DSC is obsolete and RoHS non-compliant, while A3C-8DA-2DSC(71) is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Can I use A3C-8DA-2DSC(71) in place of A3C-8DA-2DSC in existing designs?

A: Yes. The A3C-8DA-2DSC(71) is a direct substitute with identical electrical ratings (1A, 200VAC), operating temperature range (-55°C to 85°C), and mechanical interface. No design changes are required.

Q: What packaging is available for the substitute part?

A: The A3C-8DA-2DSC(71) is supplied in tube packaging. The original A3C-8DA-2DSC packaging specification was not provided.

Q: Are the contact materials the same between both parts?

A: Yes. Both connectors use phosphor bronze contacts with gold plating on mating surfaces (8.00µin thickness) and tin plating on posts (39.4µin thickness).

Q: What is the current availability status?

A: A3C-8DA-2DSC has 728 pieces in stock (obsolete status). A3C-8DA-2DSC(71) has 710 pieces in stock (active product).
