Substitute Part Grouping Explanation

The DF20EF-20DP-1V(91) qualifies as a direct substitute for the DF20F-20DP-1V(90) based on the following critical parameters:

• Connector Configuration: Both parts maintain 20 positions arranged in 2 rows with identical 0.039" (1.00mm) mating pitch and row spacing
• Electrical Specifications: Matching voltage rating (100VAC/DC), contact material (Phosphor Bronze), and contact finish (Gold)
• Mechanical Interface: Identical surface mount termination method with solder attachment
• Environmental Compliance: Both parts are RoHS Compliant with MSL 1 rating
• Manufacturer Consistency: Both manufactured by Hirose Electric Co Ltd, ensuring design continuity within the DF series family

The primary distinction is product status: DF20F-20DP-1V(90) is obsolete, while DF20EF-20DP-1V(91) maintains active status with current manufacturing support.
