• Pitch spacing: 0.100" (2.54mm)
• Contact type: Male Pin
• Connector type: Header
• Mounting type: Through Hole
• Current rating: 3A
• Voltage rating: 250V
• Operating temperature range: -35°C ~ 85°C
• Material flammability rating: UL94 V-0
• RoHS compliance: Required

The MDF7-14DP-2.54DSA(95) qualifies as a direct substitute based on identical electrical specifications and mechanical dimensions. Differences in product status (active vs. obsolete) and packaging format do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-14DP-2.54DSA(95) is the direct substitute for the obsolete MDF7-14DP-2.54DSA(55). Both parts maintain identical electrical and mechanical specifications, including current rating, voltage rating, operating temperature range, and physical dimensions. The substitute part carries active product status with confirmed inventory availability, ensuring procurement continuity. Both parts are RoHS compliant and carry equivalent regulatory certifications (UL94 V-0, ECCN EAR99, HTSUS 8536.69.4040). The packaging difference (bag format for the substitute) does not affect functional performance or board-level compatibility.
