Substitute Part Grouping Explanation

The MDF7B-30DP-2.54DSA(55) can be substituted with MDF7B-30DP-2.54DSA(95) based on the following critical parameters that remain constant across both parts:

• Series designation (MDF7)
• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (30)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Current rating (3A)
• Voltage rating (250V / 250VAC)
• Operating temperature range (-35°C ~ 85°C)
• Contact material (Brass)
• Contact finish (Tin)
• Insulation material (Polybutylene Terephthalate / PBT)
• Material flammability rating (UL94 V-0)
• RoHS compliance status

The primary distinction between these parts lies in the application style designation (55 vs. 95) and product status, with the substitute part classified as active and available in higher inventory quantities.
