Key Parameters

Substitute Part Grouping Explanation

The MDF7C-14P-2.54DSA(95) qualifies as a direct substitute based on the following critical parameters:

• Identical manufacturer (Hirose Electric Co Ltd) and series designation (MDF7)
• Matching position count (14 positions) and pitch specification (0.100"/2.54mm)
• Identical mounting configuration (through-hole, single row)
• Matching termination method (solder) and contact finish (tin-plated)
• Identical overall contact length (0.984"/25.00mm) and post length (0.118"/3.00mm)
• Equivalent electrical ratings and material specifications
• Active product status with current manufacturing availability

The primary distinction is packaging format: MDF7C-14P-2.54DSA(55) uses standard packaging, while MDF7C-14P-2.54DSA(95) is supplied in bag packaging. This difference does not affect functional or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using MDF7C-14P-2.54DSA(55), transition to MDF7C-14P-2.54DSA(95) is supported by the following factors:

• Both parts maintain identical electrical and mechanical specifications across all critical parameters
• MDF7C-14P-2.54DSA(95) holds active product status with confirmed manufacturing availability, ensuring long-term supply chain stability
• Both parts carry RoHS compliance certification and MSL Level 1 rating, meeting regulatory and environmental requirements
• The substitute part is currently in stock with 1068 units available, providing immediate procurement capability

The obsolete status of the original part necessitates transition planning. The substitute part provides functional equivalence without design modification requirements.
