Compliance & Certifications: Both parts meet UL94 V-0 flammability requirements and RoHS standards. The DF3EA-2P-2V(51) carries ROHS3 Compliant status, representing current regulatory alignment.

Electrical Specifications: The DF3EA-2P-2V(51) provides an extended operating temperature range (-55°C ~ 105°C versus -30°C ~ 85°C) and includes a specified voltage rating of 250VAC, offering broader application compatibility.

Physical & Functional Compatibility: Both connectors maintain identical mechanical dimensions, pitch, shrouding design, and termination method, ensuring direct PCB layout compatibility without redesign.

Contact Material Difference: The DF3EA-2P-2V(51) uses brass contacts versus phosphor bronze in the DF3DZ-2P-2V(51). Both materials are suitable for gold-plated mating surfaces and solder termination applications within the specified electrical parameters.

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors share identical pitch (2.00mm), mounting type (surface mount), shrouding design (4-wall), and insulation height (5.90mm). PCB footprints and mating interfaces are compatible without modification.

Q: What is the difference in contact material between these parts?

A: The DF3DZ-2P-2V(51) uses phosphor bronze contacts, while the DF3EA-2P-2V(51) uses brass contacts. Both materials are compatible with gold plating and solder termination. The choice between them does not affect functional performance in standard board-to-board or cable applications.

Q: Does the DF3EA-2P-2V(51) support the same current rating?

A: The DF3DZ-2P-2V(51) specifies 3A current rating. The DF3EA-2P-2V(51) current rating varies by wire gauge. For equivalent wire gauge applications, current capacity is comparable. The DF3EA-2P-2V(51) includes a specified voltage rating of 250VAC, providing additional electrical specification clarity.

Q: What is the operating temperature difference?

A: The DF3DZ-2P-2V(51) operates from -30°C to 85°C, while the DF3EA-2P-2V(51) operates from -55°C to 105°C. The DF3EA-2P-2V(51) supports a wider temperature range, making it suitable for applications requiring extended thermal performance.

Q: Are both parts RoHS compliant?

A: Yes. The DF3DZ-2P-2V(51) is RoHS Compliant, and the DF3EA-2P-2V(51) is ROHS3 Compliant. Both meet current RoHS requirements. The ROHS3 designation on the DF3EA-2P-2V(51) reflects the latest regulatory standard.

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

A: The DF3EA-2P-2V(51) is available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual and automated assembly processes.

Q: Why is the DF3EA-2P-2V(51) recommended over the discontinued DF3DZ-2P-2V(51)?

A: The DF3EA-2P-2V(51) is the active production equivalent within the DF3 series. It offers improved availability, extended specifications, and current regulatory compliance, making it the appropriate choice for new designs and ongoing production requirements.
