Parameter Comparison

Engineering Selection Recommendations

The DF3EA-2P-2V(51) is the appropriate substitute for the discontinued DF3DZ-2P-2V(76). Selection is based on:

• Product Availability: The DF3EA-2P-2V(51) maintains active status with 6159 units in stock, compared to the discontinued status of the original part
• Compliance Enhancement: The substitute achieves ROHS3 Compliant status versus RoHS Compliant, representing updated regulatory alignment
• Extended Operating Range: Operating temperature extends from -55°C to 105°C, providing broader thermal performance compared to -30°C to 85°C
• Contact Enhancement: Gold plating with 8.00µin (0.203µm) thickness and brass material provide improved contact reliability
• Solder Retention Feature: The substitute includes solder retention capability for enhanced manufacturing robustness
• Packaging Options: Available in Cut Tape (CT) and Digi-Reel® formats for flexible procurement

Both parts maintain identical mechanical and electrical core specifications for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Are the DF3DZ-2P-2V(76) and DF3EA-2P-2V(51) mechanically interchangeable?

A: Yes. Both connectors maintain identical pitch spacing (2.00mm), 2-position configuration, shrouded 4-wall construction, and surface mount footprint. PCB layout and mating interface compatibility are preserved.

Q: What is the difference in current rating between these parts?

A: The DF3DZ-2P-2V(76) specifies 3A current rating. The DF3EA-2P-2V(51) current rating varies by wire gauge. For equivalent wire gauge applications, current capacity is comparable or superior due to enhanced contact materials.

Q: Does the extended operating temperature range of the DF3EA-2P-2V(51) affect compatibility?

A: No. The extended range (-55°C to 105°C versus -30°C to 85°C) represents improved capability. Designs operating within the original temperature specification remain fully compatible.

Q: What is the significance of the gold-plated contacts on the substitute part?

A: Gold plating (8.00µin thickness) on the DF3EA-2P-2V(51) provides enhanced contact reliability and corrosion resistance compared to unspecified contact finish on the original part. This represents a specification improvement.

Q: Are there packaging differences between these parts?

A: The DF3DZ-2P-2V(76) packaging is not specified. The DF3EA-2P-2V(51) is available in Cut Tape (CT) and Digi-Reel® formats, providing standard procurement options.

Q: Do both parts meet the same flammability and RoHS standards?

A: Both parts meet UL94 V-0 flammability rating. The substitute achieves ROHS3 Compliant status versus RoHS Compliant on the original, representing updated regulatory compliance.

Q: What is the solder retention feature on the DF3EA-2P-2V(51)?

A: Solder retention is a manufacturing feature that maintains contact position during reflow soldering processes, improving assembly reliability and reducing defects.
