DF3Z-4P-2H(70) Equivalent & Substitute Parts

Part Overview

The DF3Z-4P-2H(70) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable connections with a 4-position, single-row configuration at 2.00mm pitch. This part is classified as obsolete and is no longer in active production. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for ongoing system support, maintenance, and new design implementations where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

The DF3EA-4P-2H(51) qualifies as a direct substitute for the DF3Z-4P-2H(70) based on the following critical parameters:

• Number of Positions & Rows: Both parts feature 4 positions in a single row
• Mating Pitch: Both maintain 0.079" (2.00mm) pitch spacing
• Connector Type: Both are header connectors
• Shrouding Configuration: Both feature shrouded 4-wall design
• Fastening Type: Both use push-pull fastening
• Voltage Rating: Both rated for 250VAC
• Operating Temperature Range: Both operate across -55°C to 105°C
• Manufacturer: Both manufactured by Hirose Electric Co Ltd within the same product family (DF3 series)

The primary difference is that DF3EA-4P-2H(51) is an active product with surface mount, right-angle mounting, whereas the original DF3Z-4P-2H(70) mounting configuration is not specified. The DF3EA variant is currently in production with full inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-4P-2H(51) is the appropriate substitute for the obsolete DF3Z-4P-2H(70) based on the following engineering criteria:

Product Status & Availability: The DF3Z-4P-2H(70) is obsolete with no ongoing production. The DF3EA-4P-2H(51) is an active product with 2961 units in current inventory, ensuring long-term supply chain continuity.

Electrical & Mechanical Compatibility: Both connectors maintain identical mating pitch (2.00mm), position count (4), row configuration (1), voltage rating (250VAC), and operating temperature range (-55°C to 105°C). The shrouded 4-wall design and push-pull fastening are preserved.

Compliance & Standards: The DF3EA-4P-2H(51) is RoHS Compliant with MSL rating of 1 (Unlimited), meeting modern regulatory requirements. The material flammability rating is UL94 V-0, suitable for applications requiring flame resistance.

Packaging & Logistics: The DF3EA-4P-2H(51) is supplied in Tape & Reel (TR) packaging, standard for automated assembly processes and high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-4P-2H(51) directly replace DF3Z-4P-2H(70) in existing designs?

A: Yes, for applications where the connector pitch, position count, voltage rating, and operating temperature are the primary design constraints. Both parts share identical mating pitch (2.00mm), 4-position single-row configuration, 250VAC rating, and -55°C to 105°C operating range. Verify that the surface mount, right-angle mounting of DF3EA-4P-2H(51) is compatible with your PCB layout requirements.

Q: What is the key difference between these two connectors?

A: The primary difference is product status and mounting configuration. DF3Z-4P-2H(70) is obsolete, while DF3EA-4P-2H(51) is an active product. DF3EA-4P-2H(51) specifies surface mount, right-angle mounting with solder termination, whereas the original part's mounting type is not documented.

Q: Are there any compliance differences?

A: DF3EA-4P-2H(51) is RoHS Compliant with UL94 V-0 flammability rating and MSL 1 (Unlimited). The original DF3Z-4P-2H(70) compliance specifications are not provided. If your application requires RoHS compliance or specific flammability ratings, DF3EA-4P-2H(51) meets these modern standards.

Q: What packaging is available for DF3EA-4P-2H(51)?

A: DF3EA-4P-2H(51) is supplied in Tape & Reel (TR) packaging, suitable for automated pick-and-place assembly and high-volume manufacturing.

Q: Is the contact finish the same?

A: DF3EA-4P-2H(51) features gold-plated mating contacts with 8.00µin (0.203µm) thickness. The original part's contact finish specification is not documented. Gold plating provides enhanced corrosion resistance and reliable electrical contact over the operating temperature range.
