Engineering Selection Recommendations

Direct Hirose Upgrade: A3A-6DA-2SV(71) is the direct successor to the A3A-6DA-2SV, maintaining identical electrical and mechanical specifications while transitioning to active product status and ROHS3 compliance. This option preserves design continuity with the original manufacturer and is recommended for applications requiring minimal design changes.

Molex Milli-Grid Series (0873810608, 0873810617): Both Molex alternatives operate at extended temperature ranges (-55°C to 105°C) and higher current ratings (1.9A). The 0873810617 includes board guide features matching the original design. These parts are ROHS3 compliant and actively manufactured. The 0873810608 provides a cost-effective alternative without board guide features.

3M 1502 Series (150206-2000-RB, 150206-2000-RB-WB): The 3M connectors offer the highest voltage rating (500VDC) and UL94 V-0 flammability certification. The 150206-2000-RB-WB variant includes pick-and-place features for automated assembly. Both are RoHS compliant and actively supported.

Amphenol ICC Minitek Series (55510-006LF, 55510-006TRLF, 55510-106LF, 55510-306LF): The Amphenol Minitek series provides the widest operating temperature range (-55°C to 125°C) and highest current capacity (2A). All variants are UL94 V-0 rated and RoHS compliant. Variants differ in contact finish thickness and packaging format. The 55510-006TRLF includes pick-and-place features for high-volume production.

Harwin M22 Series (M22-6340342): The Harwin connector offers bottom or top entry configuration flexibility, 500VAC voltage rating, and ROHS3 compliance. Operating temperature range is -40°C to 105°C with 2A current capacity. This option is suitable for applications requiring flexible connector orientation.

Compliance Considerations: All substitute parts except the Molex variants carry explicit UL94 V-0 flammability certification. For applications requiring RoHS3 compliance, A3A-6DA-2SV(71), Molex 0873810608, Molex 0873810617, and Harwin M22-6340342 are certified. The original A3A-6DA-2SV is RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can I directly replace A3A-6DA-2SV with any of these substitute parts? A: Yes. All listed substitute parts maintain identical pitch (0.079" / 2.00mm), position count (6), row configuration (2 rows), contact type (female socket), and fastening mechanism (push-pull). Mechanical and electrical compatibility is assured for board-level integration.

Q: What is the primary reason to transition from A3A-6DA-2SV? A: The A3A-6DA-2SV is classified as obsolete. Substitute parts are actively manufactured, ensuring long-term supply availability and support. Additionally, all substitutes offer improved compliance certifications, particularly RoHS3 compliance.

Q: Are there temperature limitations I should consider? A: The original A3A-6DA-2SV operates from -55°C to 85°C. Most substitutes extend this range to -55°C to 105°C or higher. If your application operates within the original temperature window, all substitutes are suitable. For applications exceeding 85°C, the Amphenol Minitek series (-55°C to 125°C) provides the widest margin.

Q: Do packaging differences affect compatibility? A: No. Packaging formats (Tube, Tray, Tape & Reel, Cut Tape) are logistics considerations only and do not affect electrical or mechanical compatibility. Select packaging based on assembly process requirements and volume.

Q: Which substitute offers the best current capacity? A: The Amphenol ICC Minitek series (55510-006LF, 55510-006TRLF, 55510-106LF, 55510-306LF) and Harwin M22-6340342 all provide 2A current rating, compared to the original 1A. This provides additional design margin for power distribution applications.

Q: What is the difference between Molex 0873810608 and 0873810617? A: Both are electrically identical. The 0873810617 includes board guide features, matching the original A3A-6DA-2SV design. The 0873810608 omits board guide features, reducing cost. Select based on PCB layout requirements.

Q: Are all substitutes UL94 V-0 rated? A: All substitutes except the Molex variants (0873810608, 0873810617) carry explicit UL94 V-0 flammability certification. For applications requiring this certification, select from Hirose A3A-6DA-2SV(71), 3M 1502 series, Amphenol Minitek series, or Harwin M22-6340342.

Q: Which substitute is recommended for high-volume automated assembly? A: The Amphenol ICC 55510-006TRLF and 3M 150206-2000-RB-WB both include pick-and-place features and are supplied in Tape & Reel or Digi-Reel packaging, optimizing for automated placement equipment.
