DF11Z-8DS-2V(50) Equivalent & Substitute Parts

Part Overview

The DF11Z-8DS-2V(50) is an 8-position receptacle connector manufactured by Hirose Electric Co Ltd, designed for surface mount board-to-board or cable applications with 0.079" (2.00mm) pitch spacing. This connector features gold-plated mating contacts, friction lock fastening, and operates across -30°C to 85°C with a 2A current rating at 250V. The product is currently obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF11Z-8DS-2V(50) is based on the following critical parameters that must align for functional equivalence:

• Connector Type & Contact Configuration: Receptacle with 8 female socket positions
• Pitch & Row Spacing: 0.079" (2.00mm) mating pitch with 2-row configuration
• Mounting Technology: Surface mount termination with solder attachment
• Electrical Performance: Current and voltage ratings sufficient for the application
• Contact Material & Finish: Gold-plated mating surface for reliable signal transmission
• Environmental Compliance: UL94 V-0 flammability rating

The A3A-8DA-2SV(71) meets these core substitution criteria as an active product from the same manufacturer, maintaining mechanical and electrical compatibility while offering improved availability and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The A3A-8DA-2SV(71) is the designated substitute for the obsolete DF11Z-8DS-2V(50). Selection of this alternative is supported by the following factors:

Product Status: The DF11Z-8DS-2V(50) is obsolete with no continued manufacturing. The A3A-8DA-2SV(71) is an active product with confirmed inventory availability (1195 pcs in stock), ensuring supply chain continuity.

Compliance & Certifications: Both connectors maintain UL94 V-0 flammability rating. The A3A-8DA-2SV(71) additionally carries ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and production.

Mechanical Compatibility: Core mechanical parameters align, including 8-position configuration, 0.079" (2.00mm) pitch, 2-row layout, and surface mount termination. The substitute features a different fastening mechanism (push-pull versus friction lock) and reduced insulation height and stacking dimensions, which may require PCB layout verification.

Electrical Derating: The A3A-8DA-2SV(71) carries lower current (1A versus 2A) and voltage (200VAC versus 250V) ratings. Applications operating at or near the original part's maximum electrical specifications require confirmation that the substitute's ratings remain adequate for the intended use case.

Frequently Asked Questions (FAQ)

Q: Can the A3A-8DA-2SV(71) directly replace the DF11Z-8DS-2V(50) without PCB modifications?

A: The connectors share identical pitch, row spacing, and contact configuration, enabling mechanical mating with existing complementary connectors. However, the substitute features reduced insulation height (0.165" versus 0.234") and different stacking heights (5.1mm/6mm versus 7.55mm/8.2mm). PCB layout verification is necessary to confirm clearance and mounting compatibility.

Q: What is the impact of the different fastening mechanism?

A: The original part uses friction lock engagement, while the substitute employs push-pull fastening. These mechanisms provide different connection security and disconnection force profiles. System design must accommodate the push-pull interface, including any changes to connector retention and mating procedures.

Q: Are the electrical rating differences significant?

A: The substitute is rated for 1A at 200VAC compared to the original 2A at 250V. Applications drawing currents below 1A or operating at voltages below 200VAC are unaffected. Designs operating at higher electrical specifications require alternative substitutes or continued use of the original part through available inventory channels.

Q: Does the A3A-8DA-2SV(71) meet current regulatory requirements?

A: Yes. The substitute carries ROHS3 compliance and maintains UL94 V-0 flammability certification, satisfying current environmental and safety standards for new product designs and manufacturing.

Q: What are the packaging and inventory considerations?

A: The A3A-8DA-2SV(71) is supplied in tube packaging with 1195 pcs currently in stock, compared to the obsolete DF11Z-8DS-2V(50) with 927 pcs available. The active status of the substitute ensures continued availability for production and field service applications.
