Parameter Comparison

Engineering Selection Recommendations

The MDF7-20P-2.54DS(95) is a direct functional equivalent to the obsolete MDF7-20P-2.54DS(55). Both parts share identical electrical ratings, mechanical specifications, and regulatory certifications. The primary distinction is product status: the MDF7-20P-2.54DS(95) maintains active production status with current inventory availability, while the MDF7-20P-2.54DS(55) is obsolete.

The contact length mating dimension variance of 0.03mm (7.42mm versus 7.45mm) falls within standard manufacturing tolerances for this connector category and does not affect functional compatibility. Both parts maintain UL94 V-0 flammability rating and RoHS compliance, ensuring regulatory alignment for applications requiring these certifications.

Selection of the MDF7-20P-2.54DS(95) is appropriate for new designs, redesigns, and replacement procurement where the MDF7-20P-2.54DS(55) is no longer available.
