Substitute Part Grouping Explanation

Substitution eligibility for the A3C-32DA-2DSC is determined by strict alignment with the following critical parameters:

32-position receptacle configuration with female socket contacts
0.079" (2.00mm) pitch mating and row spacing
2-row arrangement
Through-hole solder termination with push-pull fastening
Gold-plated mating contacts
Black insulation with UL94 V-0 flammability rating
Operating temperature range of -55°C minimum
Voltage rating of 200VAC minimum
Current rating of 1A minimum

The substitute parts listed below meet these core requirements. Variations in contact material, contact finish thickness, insulation material, and post contact specifications do not preclude substitution when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

A3C-32DA-2DSC(71) — Direct manufacturer variant from Hirose Electric Co Ltd with identical electrical and mechanical specifications to the main part. This substitute offers active product status and ROHS3 compliance, addressing the obsolescence of the original part while maintaining full compatibility. Recommended for applications requiring direct Hirose sourcing continuity.

833-93-032-10-001000 — Mill-Max Manufacturing Corp. alternative providing enhanced current rating (3A) and extended operating temperature range (-55°C ~ 125°C). This part maintains core connector geometry and gold-plated mating contacts. RoHS non-compliance status should be evaluated against application requirements.

SMM-116-01-F-D and SMM-116-01-S-D — Samtec Inc. Tiger Eye™ SMM series substitutes offering superior electrical performance with 3.2A per contact current rating and 350VAC voltage rating. Both parts feature ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C). These connectors employ Beryllium Copper contacts and Liquid Crystal Polymer insulation, providing enhanced reliability for demanding applications. Selection between F-D and S-D variants depends on specific contact finish thickness requirements.

Frequently Asked Questions (FAQ)

Q: Can A3C-32DA-2DSC(71) be used as a direct replacement for A3C-32DA-2DSC?

A: Yes. A3C-32DA-2DSC(71) is a direct manufacturer variant with identical electrical and mechanical specifications. The primary difference is product status (active vs. obsolete) and ROHS3 compliance certification. All connector dimensions, pitch, contact configuration, and electrical ratings remain unchanged.

Q: What are the key differences between Hirose and Samtec substitutes?

A: Hirose A3C-32DA-2DSC(71) maintains the original 1A current rating and 200VAC voltage specification. Samtec SMM-116-01-F-D and SMM-116-01-S-D provide higher current capacity (3.2A per contact) and voltage rating (350VAC), with extended operating temperature range to 125°C. Both Samtec parts feature Beryllium Copper contacts versus Phosphor Bronze in the original design.

Q: Does packaging affect connector compatibility?

A: Packaging (tube, bulk, or unspecified) does not affect electrical or mechanical compatibility. Packaging selection should be based on production volume, handling requirements, and inventory management practices.

Q: Are all substitute parts RoHS compliant?

A: A3C-32DA-2DSC(71), SMM-116-01-F-D, and SMM-116-01-S-D are ROHS3 compliant. The 833-93-032-10-001000 is RoHS non-compliant. Compliance requirements should be confirmed against application and regulatory specifications.

Q: What is the impact of different contact materials on substitution?

A: The original A3C-32DA-2DSC uses Phosphor Bronze contacts. Substitute parts employ Beryllium Copper (Mill-Max and Samtec) or maintain Phosphor Bronze (Hirose variant). Contact material differences do not preclude substitution when mating surface finish (gold plating) and electrical ratings meet or exceed application requirements.

Q: Can SMM-116-01-F-D and SMM-116-01-S-D be used interchangeably?

A: Both Samtec parts share identical connector geometry, pitch, row configuration, and electrical ratings. The primary difference is contact finish thickness on mating surfaces (3.00µin vs. 30.0µin). Selection depends on specific contact durability and mating cycle requirements for the application.
