Key Parameters

Substitute Part Grouping Explanation

The DF3EA-5P-2V(21) qualifies as a direct substitute based on the following critical parameters:

• Connector Series: Both parts belong to the DF3 series from Hirose Electric Co Ltd
• Position Count & Pitch: Identical 5-position configuration with 0.079" (2.00mm) mating pitch
• Contact Configuration: Male pin headers with circular contact shape
• Mounting & Termination: Surface mount with solder termination and push-pull fastening
• Shrouding: Both feature shrouded 4-wall design
• Material & Compliance: Identical polyamide insulation, brass contacts with tin finish, UL94 V-0 flammability rating, and RoHS compliance

The DF3EA variant differs in product status (active vs. discontinued) and extended operating temperature range, making it suitable for applications requiring broader thermal performance.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-5P-2V(21) is the direct functional equivalent for the discontinued DF3DZ-5P-2V(21). Selection should be based on the following factors:

Product Availability: The DF3EA variant maintains active product status with 1706 units in stock, ensuring supply chain continuity for new designs and production runs.

Compliance & Certification: Both parts meet RoHS requirements. The DF3EA carries ROHS3 compliance with REACH unaffected status, providing enhanced regulatory alignment for current procurement standards.

Thermal Performance: The DF3EA extends the operating temperature range to -55°C ~ 105°C compared to the original -30°C ~ 85°C specification. This broader range accommodates applications with more demanding thermal environments without requiring design modification.

Mechanical & Electrical Compatibility: Identical pitch, position count, contact configuration, and fastening mechanism ensure direct mechanical and electrical interchangeability in existing PCB layouts and mating connector designs.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-5P-2V(21) be used as a direct replacement for DF3DZ-5P-2V(21)?

A: Yes. Both connectors share identical mechanical dimensions, pitch, position count, contact type, and electrical ratings. The DF3EA is the active production equivalent with enhanced thermal range and current compliance status.

Q: What is the primary difference between these two part numbers?

A: The DF3DZ is discontinued while the DF3EA remains in active production. The DF3EA also features an extended operating temperature range (-55°C to 105°C versus -30°C to 85°C) and ROHS3 compliance versus RoHS compliance.

Q: Are there packaging differences between the two parts?

A: The DF3DZ packaging specification is not provided. The DF3EA is supplied in Tape & Reel (TR) format, which is standard for surface mount production volumes.

Q: Will the DF3EA work with existing mating connectors designed for the DF3DZ?

A: Yes. Both parts maintain identical pitch (2.00mm), shrouding configuration (4-wall), and contact geometry, ensuring full compatibility with existing mating connector designs.

Q: What is the current rating for the DF3EA-5P-2V(21)?

A: The DF3EA current rating varies by wire gauge. The original DF3DZ is rated at 3A. Verify wire gauge specifications for your application to confirm current capacity.

Q: Are both parts RoHS compliant?

A: Yes. The DF3DZ is RoHS Compliant. The DF3EA is ROHS3 Compliant, representing the current regulatory standard. Both parts are suitable for RoHS-regulated applications.
