Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF57-6P-1.2V(21) is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male blade contacts
• Position Count & Pitch: 6 positions at 0.047" (1.20mm) mating pitch
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Swing lock fastening type
• Material Specifications: Brass contacts with tin finish; Liquid Crystal Polymer insulation
• Environmental Ratings: Operating temperature -35°C ~ 85°C; UL94 V-0 flammability; MSL 1

The substitute part DF57H-6P-1.2V(21) meets all these criteria, with the distinction that it represents an active product variant within the DF57 series family, offering improved supply availability compared to the obsolete DF57-6P-1.2V(21).
