Substitute Part Grouping Explanation

Substitution eligibility for the MDF7P-26DP-2.54DSA is determined by strict alignment of the following critical parameters:

Connector Type & Contact Configuration: Header with male pins, 26 positions across 2 rows
Pitch Specifications: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
Electrical Ratings: 3A current capacity and 250V voltage rating
Mounting & Termination: Through-hole solder termination
Material & Compliance: Brass contacts with gold mating finish, PBT insulation, UL94 V-0 flammability rating, RoHS compliance

The substitute part MDF7P-26DP-2.54DSA(96) meets all critical substitution criteria. Both parts share identical electrical specifications, mechanical dimensions, and material composition. The primary distinction is product status: the original part is obsolete while the substitute is active, and packaging differs (unspecified for original versus bag packaging for substitute).
