Parameter Comparison

Engineering Selection Recommendations

The DF3E-3P-2H(21) is the appropriate substitute for the DF3Z-3P-2H(74). Both parts are manufactured by Hirose Electric Co Ltd within the DF3 series and share identical electrical and mechanical specifications. The substitute part maintains full compliance with RoHS requirements and UL94 V-0 flammability standards.

The primary advantage of selecting the DF3E-3P-2H(21) is its active product status and significantly higher inventory availability (2551 units versus 659 units). The substitute is supplied in Tape & Reel packaging, which is standard for production environments.

Frequently Asked Questions (FAQ)

Q: Are the DF3Z-3P-2H(74) and DF3E-3P-2H(21) electrically identical?

A: Yes. Both parts feature identical contact materials (brass), insulation materials (polyamide/nylon), operating temperature ranges (-55°C ~ 105°C), and flammability ratings (UL94 V-0). They are electrically and mechanically interchangeable.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The DF3Z-3P-2H(74) is discontinued, while the DF3E-3P-2H(21) is an active product supplied in Tape & Reel packaging. The connector specifications remain identical.

Q: Can I use the DF3E-3P-2H(21) as a direct replacement on existing PCBs designed for the DF3Z-3P-2H(74)?

A: Yes. The DF3E-3P-2H(21) maintains the same footprint, pitch spacing (0.079" / 2.00mm), mounting type (surface mount, right angle), and mechanical dimensions. No PCB redesign is required.

Q: What does the Tape & Reel packaging mean for the DF3E-3P-2H(21)?

A: Tape & Reel (TR) packaging is the standard format for automated assembly processes. Components are wound on a continuous tape with a carrier reel, enabling high-speed pick-and-place machine compatibility. This packaging is suitable for both prototype and production environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the DF3Z-3P-2H(74) and DF3E-3P-2H(21) are RoHS compliant with Moisture Sensitivity Level 1 (unlimited shelf life).
