Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF3DZ-12P-2V(73) is determined by strict equivalence across the following critical parameters:

• Connector Series & Pitch: Both parts belong to the Hirose DF3 series with identical 2.00mm mating pitch
• Position Count & Configuration: 12-position, single-row header with identical shrouded 4-wall design
• Mounting & Termination: Surface mount with solder termination and push-pull fastening
• Insulation Geometry: Matching 0.232" (5.90mm) insulation height
• Compliance Standards: Both RoHS compliant with UL94 V-0 flammability rating and MSL 1 rating

The substitute part DF3EA-12P-2V(51) maintains full mechanical and electrical compatibility within the DF3 series specification envelope. The primary distinction is product status: DF3DZ-12P-2V(73) is discontinued, while DF3EA-12P-2V(51) is active with enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-12P-2V(51) is a direct functional substitute for the discontinued DF3DZ-12P-2V(73). Both connectors maintain identical mechanical interfaces and core electrical specifications within the DF3 series platform. The DF3EA-12P-2V(51) offers enhanced specifications including extended operating temperature range (-55°C to 105°C versus -30°C to 85°C), specified contact material (brass with gold plating), and defined voltage rating (250VAC). Both parts carry RoHS compliance and UL94 V-0 flammability certification with MSL 1 rating.

Selection of DF3EA-12P-2V(51) is supported by active product status and current availability in Tape & Reel packaging, ensuring supply chain continuity for production applications.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-12P-2V(51) directly replace DF3DZ-12P-2V(73) in existing designs?

A: Yes. Both connectors share identical mechanical dimensions, pitch, position count, shrouding configuration, and solder termination method. The DF3 series design ensures full compatibility at the board interface level.

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

A: The primary difference is product status: DF3DZ-12P-2V(73) is discontinued while DF3EA-12P-2V(51) is active. The DF3EA variant specifies contact material (brass), contact finish (gold plating at 8.00µin), extended operating temperature range, and 250VAC voltage rating. These represent enhanced specifications rather than functional changes.

Q: Are there packaging differences?

A: Yes. DF3EA-12P-2V(51) is supplied in Tape & Reel (TR) packaging, which is standard for surface mount production. The original DF3DZ-12P-2V(73) packaging specification was not provided in the technical data.

Q: Do both parts meet the same compliance standards?

A: Yes. Both connectors are RoHS compliant, carry UL94 V-0 flammability rating, and have MSL 1 (Unlimited) moisture sensitivity level classification.

Q: What is the mating pitch for these connectors?

A: Both parts use 2.00mm (0.079") mating pitch, which is the standard spacing for the DF3 series 12-position header configuration.

Q: Are these connectors suitable for high-temperature applications?

A: The DF3EA-12P-2V(51) supports -55°C to 105°C operating range. The DF3DZ-12P-2V(73) operates within -30°C to 85°C. Application requirements should be evaluated against these specifications.
