Substitute Part Grouping Explanation

Substitution of the DF3DZ-4P-2H(21) is determined by strict equivalence across the following critical parameters:

• Series alignment within DF3 family
• Identical connector type (Header) and contact type (Male Pin)
• Matching pitch specification of 0.079" (2.00mm)
• Identical number of positions (4) and row configuration (1 row)
• Matching mounting type (Surface Mount, Right Angle)
• Identical shrouding design (Shrouded - 4 Wall)
• Equivalent termination method (Solder)
• Matching fastening type (Push-Pull)
• Compatible operating temperature range (-55°C ~ 105°C)
• Equivalent or superior current rating capability
• Matching material flammability rating (UL94 V-0)
• RoHS compliance status

The DF3EA-4P-2H(21) meets all substitution criteria as an active equivalent within the DF3 series.
