Parameter Comparison

Engineering Selection Recommendations

The DF3EA-10P-2V(51) is the appropriate substitute for the discontinued DF3DZ-10P-2V(73). Selection is based on the following engineering criteria:

Product Status: The DF3EA-10P-2V(51) maintains active status with Hirose Electric Co Ltd and demonstrates superior supply availability (1988 units in stock versus 678 units for the discontinued part).

Compliance & Certifications: Both parts maintain identical RoHS compliance and UL94 V-0 flammability ratings, ensuring regulatory continuity for applications requiring these certifications.

Mechanical Compatibility: The substitute part provides identical mechanical interface specifications, including footprint, pitch, shrouding configuration, and mounting type, enabling direct PCB design reuse without layout modifications.

Enhanced Operating Range: The DF3EA-10P-2V(51) extends the operating temperature range to -55°C ~ 105°C compared to the original -30°C ~ 85°C specification, providing broader environmental compatibility for extended temperature applications.

Contact Finish Enhancement: The substitute incorporates gold-plated contacts (8.00µin thickness) with brass material composition and solder retention features, improving contact reliability and durability compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can the DF3EA-10P-2V(51) be used as a direct replacement for the DF3DZ-10P-2V(73) without PCB redesign?

A: Yes. Both connectors share identical mechanical and electrical interface specifications, including 10-position 2.00mm pitch configuration, surface mount footprint, shrouded 4-wall design, and push-pull fastening. No PCB layout modifications are required.

Q: What are the key differences between these two parts?

A: The primary differences are product status (active versus discontinued), operating temperature range (-55°C ~ 105°C versus -30°C ~ 85°C), contact finish (gold-plated brass with solder retention versus unspecified), voltage rating (250VAC specified versus not specified), and packaging format (Tape & Reel versus unspecified).

Q: Are there any compatibility concerns with the extended operating temperature range?

A: The extended operating temperature range of the DF3EA-10P-2V(51) (-55°C ~ 105°C) is a superset of the original specification (-30°C ~ 85°C). Applications operating within the original temperature range experience no compatibility issues.

Q: Does the gold plating on the DF3EA-10P-2V(51) affect mating compatibility?

A: No. Gold plating improves contact reliability and corrosion resistance without affecting mechanical mating characteristics. The contact geometry and pitch remain identical to the original part.

Q: What is the significance of the Tape & Reel packaging for the substitute part?

A: Tape & Reel packaging is standard for high-volume surface mount assembly operations. This packaging format does not affect the connector's electrical or mechanical performance and is compatible with automated pick-and-place equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both the DF3DZ-10P-2V(73) and DF3EA-10P-2V(51) maintain RoHS compliance and UL94 V-0 flammability ratings, ensuring regulatory continuity for applications subject to these requirements.
