Key Parameters

Substitute Part Grouping Explanation

The substitute part MDF7-19P-2.54DSA(96) is qualified as a direct equivalent based on the following critical parameters:

• Identical manufacturer (Hirose Electric Co Ltd) and base series (MDF7)
• Matching contact configuration: 19 positions, 0.100" (2.54mm) pitch, male pin type
• Identical electrical ratings: 3A current, 250V voltage specification
• Matching mechanical dimensions: contact lengths, overall length, and insulation height
• Identical material composition: brass contacts with gold finish, PBT insulation
• Equivalent environmental specifications: -35°C ~ 85°C operating range, UL94 V-0 flammability rating
• Identical compliance: RoHS compliant, MSL 1 (Unlimited)

The primary distinction is product status: MDF7-19P-2.54DSA(01) is obsolete, while MDF7-19P-2.54DSA(96) is active. The suffix designation (01 vs. 96) indicates packaging or manufacturing revision without affecting electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-19P-2.54DSA(96) is the direct substitute for the obsolete MDF7-19P-2.54DSA(01). Both parts maintain identical electrical and mechanical specifications, with full RoHS compliance and equivalent environmental certifications. The active status of the (96) variant ensures continued availability and supply chain reliability for new designs and production continuity. Selection of MDF7-19P-2.54DSA(96) eliminates obsolescence risk while maintaining complete functional and dimensional compatibility.

Frequently Asked Questions (FAQ)
