Key Parameters

Substitute Part Grouping Explanation

The DF3EA-4P-2H(21) qualifies as a direct substitute based on the following critical parameters:

• Number of Positions: Both parts feature 4 positions, ensuring identical mating interface capacity
• Pitch - Mating: Both maintain 0.079" (2.00mm) pitch, guaranteeing mechanical and electrical compatibility
• Number of Rows: Both are single-row configurations
• Connector Type: Both are header connectors
• Style: Both support board-to-board or cable connections
• Manufacturer: Both are manufactured by Hirose Electric Co., Ltd., ensuring design consistency and quality standards

The primary difference is that DF3EA-4P-2H(21) is an active product with surface mount, right-angle mounting, whereas DF3Z-4P-2H(28) is obsolete. The DF3EA variant maintains all core electrical and mechanical parameters required for substitution while offering current production availability.

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-4P-2H(21) is the appropriate substitute for DF3Z-4P-2H(28) based on the following factors:

• Product Status Alignment: DF3EA-4P-2H(21) is an active product with full manufacturing support, eliminating supply chain risk associated with the obsolete DF3Z variant
• Regulatory Compliance: DF3EA-4P-2H(21) is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements
• Core Parameter Equivalence: All critical electrical and mechanical parameters—position count, pitch, row configuration, and connector type—are identical between the two parts
• Manufacturer Consistency: Both parts originate from Hirose Electric Co., Ltd., ensuring design philosophy and quality standards remain consistent

Selection of DF3EA-4P-2H(21) ensures continued access to a functionally equivalent connector while maintaining compliance with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can DF3EA-4P-2H(21) directly replace DF3Z-4P-2H(28) in existing designs?

A: Yes. Both connectors share identical mating pitch (2.00mm), position count (4), row configuration (1), and connector type (header). The primary difference is mounting style: DF3EA-4P-2H(21) is surface mount, right-angle, while DF3Z-4P-2H(28) specifications do not detail mounting type. Verify your PCB layout accommodates the right-angle surface mount configuration.

Q: What is the key reason for substitution?

A: DF3Z-4P-2H(28) is obsolete and no longer manufactured. DF3EA-4P-2H(21) is the active equivalent from the same manufacturer, ensuring ongoing availability and support.

Q: Are there packaging differences between these parts?

A: Yes. DF3EA-4P-2H(21) is supplied in Tape & Reel (TR) packaging, which is standard for surface mount components. Verify your procurement and assembly processes accommodate this packaging format.

Q: Does DF3EA-4P-2H(21) meet current compliance standards?

A: Yes. DF3EA-4P-2H(21) is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What are the electrical specifications of the substitute?

A: DF3EA-4P-2H(21) is rated for 250VAC operation across an operating temperature range of -55°C to 105°C. Current rating varies by wire gauge. Consult the detailed datasheet for specific current ratings applicable to your application.
