Frequently Asked Questions (FAQ)

Q: Are DF3DZ-3P-2V(21) and DF3EA-3P-2V(21) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.00mm), position count (3), shrouding configuration (4-wall), insulation height (5.90mm), and mounting type (surface mount). They are mechanically interchangeable in board-to-board and cable applications.

Q: What is the difference between the DF3DZ and DF3EA variants?

A: The primary differences are product status and operating specifications. The DF3EA is an active product with an extended operating temperature range (-55°C ~ 105°C versus -30°C ~ 85°C) and includes specified voltage rating (250VAC). Both variants belong to the DF3 series and maintain identical connector geometry and contact specifications.

Q: Can I use DF3EA-3P-2V(21) in applications originally designed for DF3DZ-3P-2V(21)?

A: Yes. The DF3EA-3P-2V(21) meets or exceeds all specifications of the discontinued DF3DZ-3P-2V(21). The extended operating temperature range and specified voltage rating make it suitable for the same applications with enhanced performance margins.

Q: What packaging options are available for the substitute part?

A: The DF3EA-3P-2V(21) is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. The DF3DZ-3P-2V(21) is RoHS Compliant, and the DF3EA-3P-2V(21) is ROHS3 Compliant. Both meet RoHS requirements with the DF3EA offering enhanced regulatory status.

Q: What is the current rating for the DF3EA-3P-2V(21)?

A: The DF3EA-3P-2V(21) current rating varies by wire gauge. The original DF3DZ-3P-2V(21) specifies 3A. Consult the detailed product datasheet for specific current ratings based on your wire gauge selection.
