Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF57-2P-1.2V(21) is determined by strict alignment of the following critical parameters:

• Number of Positions: 2
• Pitch - Mating: 0.047" (1.20mm)
• Connector Type: Header
• Contact Type: Male Blade
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Swing Lock
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature Range: -35°C ~ 85°C
• Material Flammability Rating: UL94 V-0

The substitute part DF57H-2P-1.2V(21) maintains all critical electrical and mechanical parameters required for direct substitution. The primary distinction is the product status transition from Obsolete to Active, along with enhanced compliance certifications and improved packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The DF57H-2P-1.2V(21) is the direct substitute for the obsolete DF57-2P-1.2V(21). Both connectors share identical electrical and mechanical specifications, ensuring functional compatibility in existing designs.
