Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5-1734516-8 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Criteria:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 8
• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Shape: Square
• Contact Material: Phosphor Bronze
• Material Flammability Rating: UL94 V-0

All substitute parts listed meet these core criteria. Variations in secondary parameters such as contact finish thickness, insulation material, insulation height, operating temperature range, voltage rating, and current rating are noted in the comparison table and do not preclude substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active status products with ROHS3 compliance and EAR99 classification, meeting regulatory requirements equivalent to the primary part 5-1734516-8.

Hirose A3-8DA-2SV(71): This substitute maintains full mechanical and electrical compatibility with identical pitch, row spacing, and contact configuration. The lower operating temperature maximum (-55°C to 85°C versus -40°C to 105°C) and reduced voltage rating (200VAC versus 250VAC) require verification against application specifications. Contact finish thickness is reduced (8.00µin versus 30.0µin), and insulation material differs (PPS versus Thermoplastic). Suitable for applications within the specified temperature and voltage envelope.

Hirose A3A-8DA-2SV(71): This variant includes a board guide feature and is otherwise identical to the A3-8DA-2SV(71) in electrical and mechanical characteristics. The board guide provides mechanical alignment benefit during assembly. Same temperature and voltage limitations apply.

Harwin M22-6340442: This substitute offers enhanced electrical ratings (2A current, 500VAC voltage) compared to the primary part (1A, 250VAC), providing margin for higher-power applications. Operating temperature range matches the primary part (-40°C to 105°C). The connector supports bottom or top entry configuration, offering design flexibility. Insulation material is Polyamide (PA6T) Nylon 6T. Contact finish is specified as Flash rather than a defined thickness. Suitable for applications requiring higher voltage and current capacity.

All substitute parts are available in production quantities and maintain the same solder termination and push-pull fastening mechanism.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A3-8DA-2SV(71) be used as a direct replacement for the TE Connectivity 5-1734516-8?

A: The A3-8DA-2SV(71) is mechanically and electrically compatible for applications operating within -55°C to 85°C and 200VAC maximum. If the application requires the full -40°C to 105°C range or 250VAC rating of the primary part, this substitute is not suitable. Verify application requirements before substitution.

Q: What is the difference between the Hirose A3-8DA-2SV(71) and A3A-8DA-2SV(71)?

A: The A3A-8DA-2SV(71) includes a board guide feature for improved mechanical alignment during assembly. All other electrical and mechanical parameters are identical. The board guide is a design enhancement with no impact on electrical performance.

Q: When should the Harwin M22-6340442 be selected over the primary TE Connectivity part?

A: The M22-6340442 is selected when the application requires higher current capacity (2A versus 1A) or higher voltage rating (500VAC versus 250VAC). The operating temperature range is equivalent (-40°C to 105°C). The bottom or top entry configuration also provides design flexibility not available in the primary part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and meet the same regulatory classification as the primary part 5-1734516-8.

Q: What packaging differences exist between the primary part and substitutes?

A: The primary part 5-1734516-8 is supplied in Tape & Reel (TR) packaging. The Hirose substitutes (A3-8DA-2SV(71) and A3A-8DA-2SV(71)) are supplied in Tube packaging. The Harwin M22-6340442 is supplied in Tube packaging. Packaging format does not affect connector performance but may impact procurement and handling procedures.

Q: Can the contact finish thickness variation affect connector performance?

A: Contact finish thickness variations (30.0µin for the primary part, 8.00µin for Hirose substitutes, and Flash for Harwin) do not preclude substitution. All parts maintain gold mating contact finish. Thickness differences reflect manufacturing specifications and do not impact electrical conductivity or mechanical engagement for the specified current and voltage ratings.

Q: What is the significance of the different insulation materials?

A: The primary part uses Thermoplastic insulation, while Hirose substitutes use Polyphenylene Sulfide (PPS) and the Harwin substitute uses Polyamide (PA6T) Nylon 6T. All materials meet UL94 V-0 flammability requirements. Material selection reflects manufacturer design choices and does not impact electrical performance within specified operating parameters. Application environment and temperature requirements should guide material selection.

Q: Are the Hirose and Harwin connectors compatible with the same mating plugs as the TE Connectivity part?

A: All substitute parts maintain identical pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), number of positions (8), and row configuration (2 rows). Mechanical compatibility with mating plugs is ensured. Verify mating plug specifications to confirm compatibility with specific connector series.
