Key Parameters

Substitute Part Grouping Explanation

The DF57H-2P-1.2V(21) qualifies as a direct substitute based on the following critical parameters:

• Number of Positions: Both parts feature 2 positions
• Pitch - Mating: Both maintain 0.047" (1.20mm) pitch spacing
• Mounting Type: Both are surface mount configurations
• Connector Type: Both are headers with male blade contacts
• Termination: Both use solder termination
• Operating Temperature Range: Both operate -35°C ~ 85°C
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• RoHS Compliance: Both meet RoHS requirements
• Manufacturer: Both manufactured by Hirose Electric Co Ltd

The primary distinction is product status: the DF57H series is active production, whereas the DF57J series is obsolete.
