Key Parameters

Substitute Part Grouping Explanation

The DF3E-2P-2H(24) qualifies as a direct substitute for DF3E-2P-2H(20) based on the following critical parameters:

• Identical series designation (DF3)
• Matching connector type, contact type, and position count (Header, Male Pin, 2-position)
• Identical mating pitch (0.079" / 2.00mm)
• Identical mounting configuration (Surface Mount, Right Angle)
• Matching shrouding design (Shrouded - 4 Wall)
• Identical termination method (Solder)
• Identical fastening type (Push-Pull)
• Matching electrical ratings (250VAC, -55°C ~ 105°C)
• Identical material flammability compliance (UL94 V-0)

The primary distinction between these parts is product status: DF3E-2P-2H(20) is obsolete, while DF3E-2P-2H(24) is active and available in higher inventory quantities.

Parameter Comparison

Engineering Selection Recommendations

The DF3E-2P-2H(24) is the appropriate selection for new designs and production applications. This part maintains active product status with Hirose Electric Co Ltd and carries explicit ROHS3 compliance and REACH unaffected certification.
