A3C-6DA-2DSA Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The A3C-6DA-2DSA is a 6-position receptacle connector manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch mating. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The main part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts maintain functional compatibility while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 6 positions at 0.079" (2.00mm) mating pitch
• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Through-hole solder termination
• Fastening Mechanism: Push-pull fastening
• Contact Finish: Gold-plated mating surface
• Electrical Performance: Minimum 1A current rating and 200VAC voltage rating
• Environmental Rating: UL94 V-0 flammability compliance

The following parts meet these substitution criteria:

1. A3C-6DA-2DSA(71) - Direct variant with improved RoHS3 compliance
2. 833-87-006-10-001101 - Preci-Dip equivalent with enhanced current rating
3. SMM-103-01-S-D - Samtec Tiger Eye™ series with superior electrical specifications

Parameter Comparison

Engineering Selection Recommendations

A3C-6DA-2DSA(71) is the primary substitute for direct replacement. This part is a variant of the main part manufactured by Hirose Electric Co Ltd with identical electrical and mechanical specifications. The key advantage is active product status and ROHS3 compliance, addressing the obsolescence of the original A3C-6DA-2DSA while maintaining full functional compatibility.

833-87-006-10-001101 from Preci-Dip provides an alternative with enhanced current rating (3A versus 1A) and extended operating temperature range (-55°C ~ 125°C). This part is suitable for applications requiring higher current capacity. The connector type designation differs (Socket versus Receptacle), but functional compatibility is maintained through identical mating pitch, row configuration, and push-pull fastening.

SMM-103-01-S-D from Samtec Inc. offers the highest electrical performance specifications with 3.2A per contact current rating and 350VAC voltage rating. This part features extended operating temperature range (-55°C ~ 125°C) and is suitable for demanding applications. All three substitute parts maintain ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

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

A: Yes. A3C-6DA-2DSA(71) is a direct variant with identical electrical and mechanical specifications. The primary difference is product status (active versus obsolete) and RoHS3 compliance. Mating pitch, row configuration, contact type, and fastening mechanism are identical.

Q: What are the key differences between the substitute parts?

A: All substitutes maintain the 6-position, 0.079" (2.00mm) pitch configuration and push-pull fastening. Primary differences are current rating (1A for A3C-6DA-2DSA(71) versus 3A for 833-87-006-10-001101 and 3.2A for SMM-103-01-S-D), voltage rating (200VAC for Hirose parts versus 350VAC for Samtec), and operating temperature range (85°C maximum for Hirose versus 125°C for Preci-Dip and Samtec).

Q: Are all substitute parts RoHS3 compliant?

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

Q: What is the difference between Receptacle and Socket connector types in this context?

A: Both connector types feature female socket contacts and are functionally compatible for mating with standard pin headers at 0.079" (2.00mm) pitch. The terminology difference reflects manufacturer classification but does not affect electrical or mechanical compatibility.

Q: Can I use SMM-103-01-S-D in applications rated for 200VAC?

A: Yes. SMM-103-01-S-D is rated for 350VAC, which exceeds the 200VAC requirement of the original part. Higher voltage rating provides additional safety margin.

Q: Are there packaging differences between substitute parts?

A: Yes. A3C-6DA-2DSA is supplied in standard packaging, A3C-6DA-2DSA(71) in Tray, 833-87-006-10-001101 in Bulk, and SMM-103-01-S-D in Bulk. Packaging does not affect connector functionality.
