Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF57-2P-2.4V(21) is based on strict equivalence of the following critical parameters:

• Connector type (Header)
• Contact type (Male Blade)
• Number of positions (2)
• Mating pitch (0.094" / 2.40mm)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Fastening type (Swing Lock)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Brass)
• Contact finish (Tin on both mating and post surfaces)
• Insulation height (0.055" / 1.40mm)
• Operating temperature range (-35°C ~ 85°C)
• Flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

The substitute part DF57H-2P-2.4V(21) maintains all these parameters, ensuring functional and mechanical compatibility with the original part.
