Key Parameters

Substitute Part Grouping Explanation

The DF3EA-3P-2V(51) qualifies as a direct substitute for the DF3DZ-3P-2V(51) based on the following critical parameters that determine functional compatibility:

• Manufacturer: Hirose Electric Co Ltd (same manufacturer)
• Series: DF3 (same connector series)
• Number of Positions: 3 (identical)
• Pitch - Mating: 0.079" (2.00mm) (identical)
• Connector Type: Header (identical)
• Contact Type: Male Pin (identical)
• Mounting Type: Surface Mount (identical)
• Shrouding: Shrouded - 4 Wall (identical)
• Termination: Solder (identical)
• Fastening Type: Push-Pull (identical)
• Insulation Height: 0.232" (5.90mm) (identical)
• Contact Shape: Circular (identical)
• Contact Finish - Mating: Gold (identical)
• Insulation Material: Polyamide (PA), Nylon (identical)
• Material Flammability Rating: UL94 V-0 (identical)
• Insulation Color: Beige (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

These parameters define the mechanical and electrical interface requirements for board-to-board connectivity. The substitute part maintains full compatibility across all critical mating and mounting dimensions.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-3P-2V(51) is the appropriate substitute for the discontinued DF3DZ-3P-2V(51). Both parts maintain identical mechanical and electrical interface specifications across all critical parameters including pitch, position count, shrouding configuration, and termination method.

The DF3EA-3P-2V(51) offers the following advantages:

• Active product status with current inventory availability
• Extended operating temperature range (-55°C ~ 105°C versus -30°C ~ 85°C)
• ROHS3 compliance status
• REACH unaffected designation
• Specified voltage rating of 250VAC
• Documented mated stacking heights (7.5mm, 7.7mm, 8.4mm)

The contact material differs (Brass in the substitute versus Phosphor Bronze in the original), but both materials with gold plating provide equivalent electrical performance for standard board-to-board connector applications. The substitute part is suitable for direct replacement in existing designs without modification to PCB layouts or mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can the DF3EA-3P-2V(51) be used as a direct replacement for the DF3DZ-3P-2V(51)?

A: Yes. Both connectors share identical mechanical dimensions, pitch spacing (2.00mm), position count (3), shrouding configuration, and solder termination method. The connectors are mechanically and electrically interchangeable for board-to-board applications.

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

A: The DF3DZ-3P-2V(51) uses Phosphor Bronze contacts while the DF3EA-3P-2V(51) uses Brass contacts. Both materials are plated with gold for mating surfaces and provide equivalent electrical conductivity and contact reliability in standard applications.

Q: Does the extended operating temperature range of the DF3EA-3P-2V(51) affect compatibility?

A: No. The extended range (-55°C ~ 105°C) of the substitute part is a superset of the original part's range (-30°C ~ 85°C). The substitute part operates safely within the original part's specified temperature limits and provides additional capability for wider temperature applications.

Q: Are there packaging differences between these parts?

A: The DF3DZ-3P-2V(51) packaging is not specified in available data. The DF3EA-3P-2V(51) is available in Cut Tape (CT) and Digi-Reel packaging options. Verify packaging requirements for your procurement process.

Q: What is the significance of the ROHS3 compliance status of the substitute part?

A: ROHS3 compliance indicates adherence to the current Restriction of Hazardous Substances Directive. The substitute part meets current regulatory requirements for electronic component manufacturing and is suitable for applications requiring ROHS3 certification.

Q: Are the mated stacking heights relevant for my application?

A: Mated stacking heights (7.5mm, 7.7mm, 8.4mm) for the DF3EA-3P-2V(51) define the distance between mated connector pairs. Verify these dimensions against your PCB layout and enclosure constraints to ensure adequate clearance in your specific application.
