Mechanical & Electrical Compatibility: All critical parameters determining connector compatibility are identical, including pitch, position count, shrouding configuration, and insulation dimensions. The substitute operates across an expanded temperature range (-55°C ~ 105°C vs. -30°C ~ 85°C), providing enhanced thermal performance for demanding applications.

Packaging Consideration: The DF3EA-4P-2V(51) is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the DF3DZ-4P-2V(73) and DF3EA-4P-2V(51) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.00mm), position count (4), shrouding configuration (4-wall), and insulation height (5.90mm). They are designed for the same mating interfaces and mounting footprints.

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

A: The primary differences are product status and operating temperature range. The DF3EA-4P-2V(51) is currently in active production with expanded temperature capability (-55°C ~ 105°C vs. -30°C ~ 85°C). The substitute also includes contact finish specifications (Gold plating, 8.00µin thickness) and solder retention features not detailed in the original part specification.

Q: Does the packaging format affect compatibility?

A: No. The DF3EA-4P-2V(51) is supplied in Tape & Reel (TR) format for automated assembly, while the original part packaging is unspecified. The connector itself is functionally identical regardless of packaging format.

Q: Are both parts RoHS compliant?

A: Yes. The DF3DZ-4P-2V(73) is RoHS Compliant, and the DF3EA-4P-2V(51) is ROHS3 Compliant, meeting current regulatory standards.

Q: Can the DF3EA-4P-2V(51) be used in applications requiring the original -30°C ~ 85°C temperature range?

A: Yes. The substitute's expanded operating range (-55°C ~ 105°C) encompasses the original specification, making it suitable for all applications within the original temperature limits.
