Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A3C-6DA-2DSC is determined by the following critical parameters: 6-position configuration, 0.079" (2.00mm) pitch mating, 2-row layout with 0.079" row spacing, through-hole solder termination, push-pull fastening, and gold-plated mating contacts. All substitute parts must maintain these core electrical and mechanical specifications to ensure PCB footprint compatibility and functional interchangeability.

The substitute parts are grouped as follows:

Direct Hirose Variant: A3C-6DA-2DSC(71) maintains identical specifications to the main part with the distinction of active product status and RoHS compliance.

Cross-Manufacturer Substitutes: 833-87-006-10-001101 (Preci-Dip) and SMM-103-01-S-D (Samtec) provide functional equivalence with variations in contact material, insulation material, and performance ratings while preserving the critical mating pitch, position count, and termination method.

Parameter Comparison

Engineering Selection Recommendations

A3C-6DA-2DSC(71) is the primary substitute for the obsolete A3C-6DA-2DSC. This variant is manufactured by Hirose Electric Co Ltd and maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. Selection of this part eliminates obsolescence risk and provides regulatory alignment for new designs.

833-87-006-10-001101 (Preci-Dip) provides functional equivalence with extended operating temperature range (-55°C ~ 125°C) and higher current rating (3A). This part is suitable for applications requiring enhanced thermal performance. The contact material differs (Beryllium Copper vs. Phosphor Bronze), and insulation material is Liquid Crystal Polymer (LCP) glass-filled rather than PBT.

SMM-103-01-S-D (Samtec Tiger Eye™ SMM series) offers the highest performance specifications with 3.2A per contact current rating and 350VAC voltage rating. Extended operating temperature range (-55°C ~ 125°C) and Beryllium Copper contacts provide superior electrical performance. This part is appropriate for demanding applications where enhanced current capacity and voltage tolerance are required.

All substitute parts maintain RoHS and REACH compliance status, supporting modern procurement and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can A3C-6DA-2DSC(71) be used as a direct replacement for A3C-6DA-2DSC?

A: Yes. A3C-6DA-2DSC(71) maintains identical mating pitch (0.079"), position count (6), row configuration (2 rows), termination method (solder), and fastening type (push-pull). PCB footprint compatibility is assured. The primary difference is active product status and RoHS compliance.

Q: What are the key differences between the Hirose A3C-6DA-2DSC(71) and the Samtec SMM-103-01-S-D?

A: Both connectors share the same mating pitch, position count, and row spacing. The Samtec part offers higher current rating (3.2A per contact vs. 1A), higher voltage rating (350VAC vs. 200VAC), and extended operating temperature range (-55°C ~ 125°C vs. -55°C ~ 85°C). Contact material differs (Beryllium Copper vs. Phosphor Bronze), and insulation material is LCP rather than PBT.

Q: Is the Preci-Dip 833-87-006-10-001101 compatible with the original A3C-6DA-2DSC footprint?

A: Yes. The 833-87-006-10-001101 maintains the same mating pitch (0.079"), position count (6), row spacing (0.079"), and through-hole solder termination. PCB layout compatibility is preserved. The part designation as "Socket" rather than "Receptacle" reflects manufacturer terminology; both are female socket connectors.

Q: Which substitute part should be selected for new designs?

A: A3C-6DA-2DSC(71) is recommended for direct replacement of the obsolete part. For applications requiring enhanced performance, SMM-103-01-S-D provides higher current and voltage ratings. Selection depends on application requirements for current capacity, voltage tolerance, and operating temperature range.

Q: Are all substitute parts RoHS compliant?

A: Yes. A3C-6DA-2DSC(71), 833-87-006-10-001101, and SMM-103-01-S-D are all RoHS compliant (RoHS or ROHS3 status). The original A3C-6DA-2DSC is RoHS non-compliant.

Q: What packaging options are available for these substitute parts?

A: A3C-6DA-2DSC(71) is supplied in Tray packaging. 833-87-006-10-001101 is supplied in Bulk packaging. SMM-103-01-S-D is supplied in Bulk packaging. Packaging selection may affect procurement lead times and handling requirements.
