Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-12P-2.54DSA(55) is determined by the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Pitch spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Current rating (3A minimum)
• Voltage rating (250V minimum)
• Operating temperature range (-35°C ~ 85°C)
• Material compliance (RoHS Compliant, UL94 V-0)

The MDF7-12P-2.54DSA(95) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both parts share identical pitch spacing, position count, contact configuration, and electrical ratings. The primary distinction lies in connector style classification and product status, with the substitute part designated as active inventory.

Parameter Comparison
