Frequently Asked Questions (FAQ)

Q: Can the DF3EA-2P-2V(51) be used as a direct replacement for the DF3DZ-2P-2V(73)?

A: Yes. Both connectors share identical mechanical and electrical specifications for the critical parameters that determine substitution compatibility: 2-position configuration, 2.00mm pitch, surface mount technology, shrouded 4-wall design, push-pull fastening, and polyamide nylon insulation. The DF3EA-2P-2V(51) is the manufacturer-designated substitute with active product status.

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

A: The primary differences are product status and enhanced specifications. The DF3EA-2P-2V(51) is active production with extended operating temperature range (-55°C to 105°C), gold-plated contact finish with 8.00µin thickness, brass contact material, and documented 250VAC voltage rating. The original DF3DZ-2P-2V(73) is discontinued and lacks these detailed specifications.

Q: Are there packaging differences between these parts?

A: Yes. The DF3DZ-2P-2V(73) packaging is not specified. The DF3EA-2P-2V(51) is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing standard component distribution options.

Q: Will the DF3EA-2P-2V(51) work in applications requiring the original -30°C to 85°C temperature range?

A: Yes. The DF3EA-2P-2V(51) operating range of -55°C to 105°C encompasses the original specification, ensuring compatibility for all applications within the original temperature envelope.

Q: Are there any compliance considerations for switching to the DF3EA-2P-2V(51)?

A: Both parts maintain UL94 V-0 flammability certification and MSL 1 moisture sensitivity. The DF3EA-2P-2V(51) carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements without additional qualification.

Q: What is the mated stacking height for the DF3EA-2P-2V(51)?

A: The DF3EA-2P-2V(51) supports mated stacking heights of 7.5mm, 7.7mm, and 8.4mm, providing flexibility for multi-connector applications.
