Key Parameters

Substitute Part Grouping Explanation

The MDF7-21P-2.54DSA(96) qualifies as a direct substitute based on the following critical parameters:

• Identical connector type (Header), contact type (Male Pin), and pitch (0.100"/2.54mm)
• Matching position count (21 positions, single row)
• Identical electrical ratings (3A current, 250V voltage)
• Identical operating temperature range (-35°C ~ 85°C)
• Matching contact material (Brass) and insulation material (PBT)
• Identical mounting method (Through Hole, Solder termination)
• Identical contact geometry (Square shape, 0.394" mating length, 0.118" post length)
• Matching compliance certifications (RoHS Compliant, UL94 V-0)

The primary distinction is product status: MDF7-21P-2.54DSA(01) is obsolete, while MDF7-21P-2.54DSA(96) is active with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations
