Parameter Comparison

Engineering Selection Recommendations

The DF3E-2P-2H(21) is the appropriate substitute for the discontinued DF3Z-2P-2H(74). Both connectors share identical electrical and mechanical specifications within the DF3 series. The DF3E-2P-2H(21) offers the advantage of active product status with higher inventory availability (5664 Pcs in stock versus 792 Pcs for the original part). The substitute maintains full compliance with RoHS and UL94 V-0 flammability requirements. The DF3E variant includes tin contact finish specifications and ROHS3 compliance, representing a current-generation equivalent suitable for direct replacement in new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the DF3E-2P-2H(21) be used as a direct replacement for the DF3Z-2P-2H(74)?

A: Yes. Both connectors share identical pitch (2.00mm), position count (2), mounting configuration (surface mount right-angle), shrouding (4-wall), and operating temperature range (-55°C ~ 105°C). The electrical and mechanical interfaces are fully compatible.

Q: What is the difference between the DF3Z and DF3E variants?

A: Both are part of the Hirose DF3 series with matching core specifications. The primary difference is product lifecycle status: DF3Z-2P-2H(74) is discontinued, while DF3E-2P-2H(21) is active. The DF3E includes specified contact finish (tin) and ROHS3 compliance.

Q: Are there packaging differences between these parts?

A: The DF3Z-2P-2H(74) packaging is not specified in available data. The DF3E-2P-2H(21) is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly.

Q: Do both connectors meet the same compliance standards?

A: Both connectors meet UL94 V-0 flammability requirements and RoHS compliance. The DF3E-2P-2H(21) carries ROHS3 certification, representing the current regulatory standard.

Q: What is the current rating for these connectors?

A: The DF3Z-2P-2H(74) is rated for 3A. The DF3E-2P-2H(21) current rating varies by wire gauge, consistent with standard connector specifications for this series.
