Parameter Comparison

Engineering Selection Recommendations

The DF3EA-12P-2V(21) is the direct substitute for the discontinued DF3DZ-12P-2V(21). Both parts maintain identical mechanical and electrical specifications for the core connector interface, including pitch, position count, shrouding, and contact configuration. The DF3EA-12P-2V(21) offers active product status, ensuring ongoing availability and supply chain continuity.

The DF3EA-12P-2V(21) provides an extended operating temperature range (-55°C to 105°C versus -30°C to 85°C), which accommodates broader environmental conditions without compromising the original design envelope. Both parts carry identical RoHS compliance and UL94 V-0 flammability certification, maintaining regulatory and safety requirements.

Selection of the DF3EA-12P-2V(21) is appropriate for new designs and replacement procurement where the DF3DZ-12P-2V(21) is no longer available.

Frequently Asked Questions (FAQ)

Q: Are DF3DZ-12P-2V(21) and DF3EA-12P-2V(21) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (2.00mm), position count (12), shrouding configuration (4-wall), and mounting method (surface mount). Physical dimensions and mating interfaces are equivalent.

Q: What is the difference in current rating between these parts?

A: The DF3DZ-12P-2V(21) specifies 3A current rating. The DF3EA-12P-2V(21) current rating varies by wire gauge. Consult the detailed product specifications for the specific wire gauge configuration required in your application.
