Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDF7-9S-2.54DSA(56) is determined by the following critical parameters:

• Connector Type & Configuration: Receptacle, bottom entry, board-to-board style
• Position Count & Pitch: 9 positions at 0.100" (2.54mm) mating pitch
• Electrical Ratings: 3A current capacity, 250VAC voltage rating
• Mounting & Termination: Through-hole solder termination
• Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1

The MDF7-9S-2.54DSA(96) qualifies as a direct substitute based on identical mechanical configuration, electrical specifications, and environmental ratings. The primary distinction is product status: the substitute part is active, whereas the original is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-9S-2.54DSA(96) is the direct substitute for the obsolete MDF7-9S-2.54DSA(56). Both parts share identical mechanical dimensions, electrical ratings, and environmental specifications. The substitute part carries active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment for new designs and production runs. Selection of the active part eliminates obsolescence risk and maintains full compatibility with existing board layouts and mating connectors.
