A3-8DA-2SV Equivalent & Substitute Parts

Part Overview

The A3-8DA-2SV is an 8-position receptacle connector manufactured by Hirose Electric Co Ltd, featuring 0.079" (2.00mm) pitch surface mount gold contacts. This connector is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The part operates across a temperature range of -55°C to 85°C with a 1A current rating and 200VAC voltage rating, serving general purpose and telecommunications applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: 8-position configuration, 0.079" (2.00mm) pitch, 2-row layout with 0.079" row spacing, surface mount solder termination, push-pull fastening, gold mating contact finish, and UL94 V-0 flammability rating. All identified substitutes meet these baseline mechanical and electrical requirements. Variations in contact finish thickness, insulation material, insulation height, operating temperature range, current rating, and voltage rating are documented but do not disqualify substitution eligibility when the core parameters align. Product status (active vs. obsolete) and RoHS compliance are noted for procurement and regulatory considerations.

Engineering Selection Recommendations

A3-8DA-2SV(71) is the direct Hirose equivalent with identical electrical and mechanical specifications. This part is active and ROHS3 compliant, making it the primary replacement for obsolete A3-8DA-2SV stock.

For multi-source procurement strategies, the Amphenol ICC Minitek 2.00mm series (55510-008LF, 55510-008TRLF, 55510-108LF, 55510-108TRLF) provides active alternatives with enhanced current ratings (2A) and extended operating temperature range (-55°C to 125°C). These parts are RoHS compliant and widely available.

Molex Milli-Grid series (0872630893, 0873819016) and 3M 1502 series (150208-2000-RB-WB) are active alternatives with higher voltage and current ratings. The Molex 0873819016 offers 1.9A current capacity and 105°C maximum temperature. The 3M part supports 500VDC operation.

Harwin M22-6340442 provides 2A current rating and 500VAC voltage rating with ROHS3 compliance and active product status.

Samtec SMM-104-02-F-D offers the highest current rating (3.2A per contact) and 350VAC voltage rating with ROHS3 compliance, suitable for applications requiring enhanced electrical performance.

Frequently Asked Questions (FAQ)

Q: Can A3-8DA-2SV be directly replaced with A3-8DA-2SV(71)?

A: Yes. A3-8DA-2SV(71) is the direct Hirose equivalent with identical electrical and mechanical specifications. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What are the key compatibility criteria for substitution?

A: All substitutes must maintain 8-position configuration, 0.079" (2.00mm) pitch, 2-row layout with 0.079" row spacing, surface mount solder termination, push-pull fastening, gold mating contact finish, and UL94 V-0 flammability rating.

Q: Do substitute parts have different current or voltage ratings?

A: Yes. Substitute parts offer current ratings ranging from 1A to 3.2A per contact and voltage ratings from 125V to 500VAC/VDC. Applications requiring the original 1A/200VAC specification can use any substitute. Applications with higher electrical demands should select parts with appropriate ratings.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (LF suffix) is suitable for manual assembly and lower-volume production. Tape & reel packaging (TRLF suffix) is optimized for automated pick-and-place assembly and high-volume manufacturing.

Q: Are all substitutes RoHS compliant?

A: The original A3-8DA-2SV is RoHS non-compliant. All identified substitutes are RoHS compliant or ROHS3 compliant. Some Amphenol ICC parts (55510-008TRLF, 55510-108LF, 55510-108TRLF) are REACH Affected.

Q: Which substitute offers the best thermal performance?

A: Amphenol ICC Minitek series, Samtec SMM-104-02-F-D, and Molex alternatives support -55°C to 125°C operating range, compared to the original -55°C to 85°C specification.
