Key Parameters

Substitute Part Grouping Explanation

The DF3EA-10P-2H(21) qualifies as a direct substitute for the DF3DZ-10P-2H(21) based on the following critical parameters:

• Connector Type & Configuration: Both are header connectors with identical 10-position, single-row configuration
• Pitch & Spacing: Both maintain 0.079" (2.00mm) mating pitch
• Mounting & Orientation: Both feature surface mount, right-angle mounting
• Shrouding & Fastening: Both employ shrouded 4-wall design with push-pull fastening
• Electrical & Thermal Specifications: Both operate across -55°C ~ 105°C temperature range with UL94 V-0 flammability rating
• Material Composition: Both use brass contacts with tin finish and polyamide/nylon insulation
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The primary distinction is product status: the DF3DZ variant is obsolete, while the DF3EA variant is active and available in standard packaging (Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The DF3EA-10P-2H(21) is the direct active equivalent for the obsolete DF3DZ-10P-2H(21). Selection of the DF3EA variant is supported by:

• Product Status: The DF3EA is actively manufactured and stocked, ensuring long-term availability and supply chain continuity
• Compliance: The DF3EA carries RoHS compliance certification, meeting current regulatory requirements for electronic components
• Electrical & Mechanical Equivalence: All critical parameters—pitch, position count, mounting configuration, temperature range, and flammability rating—are identical
• Packaging: The DF3EA is supplied in standard Tape & Reel packaging, suitable for automated assembly processes

No alternative substitutes from competing manufacturers are provided in the reference data. The DF3EA-10P-2H(21) represents the sole active equivalent within the Hirose DF3 series for this connector configuration.
