Frequently Asked Questions (FAQ)

Q: Can DF3EA-12P-2V(51) be used as a direct replacement for DF3DZ-12P-2V(51) without PCB redesign?

A: Yes. Both connectors share identical mechanical envelope, mating pitch (2.00mm), position count (12), shrouding configuration (4-wall), and fastening mechanism (push-pull). No PCB layout modification is required.

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

A: DF3DZ-12P-2V(51) uses Phosphor Bronze contacts, while DF3EA-12P-2V(51) uses Brass contacts. Both materials are gold-plated for mating surfaces and provide equivalent electrical performance in this connector class.

Q: Does the extended operating temperature range of DF3EA-12P-2V(51) affect compatibility?

A: No. The DF3EA-12P-2V(51) operating range (-55°C ~ 105°C) encompasses the DF3DZ-12P-2V(51) range (-30°C ~ 85°C). Applications designed for the original part will operate within the substitute's rated temperature envelope.

Q: What packaging format should be selected for production assembly?

A: The DF3EA-12P-2V(51) is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. This packaging format is preferred for high-volume production compared to bulk packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both DF3DZ-12P-2V(51) and DF3EA-12P-2V(51) are RoHS Compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Q: What is the current rating specification for these connectors?

A: DF3DZ-12P-2V(51) is rated at 3A. DF3EA-12P-2V(51) current rating varies by wire gauge. Consult the connector datasheet for specific wire gauge current ratings to ensure application compatibility.
