Key Parameters

Substitute Part Grouping Explanation

The MDF7C-15P-2.54DSA(95) qualifies as a direct substitute based on the following critical parameters:

• Manufacturer & Series: Both parts are manufactured by Hirose Electric Co Ltd within the MDF7 series
• Connector Configuration: Identical 15-position, single-row layout with 0.100" (2.54mm) pitch
• Mounting & Termination: Both use through-hole mounting with solder termination
• Contact Specifications: Tin-plated posts with matching overall pin length of 0.984" (25.00mm)
• Electrical & Environmental Compliance: Both are RoHS compliant with MSL 1 rating
• Regulatory Classification: Identical ECCN (EAR99) and HTSUS codes

The primary distinction is that MDF7C-15P-2.54DSA(95) maintains active product status, making it the recommended sourcing option for new applications and replacements.

Parameter Comparison

Engineering Selection Recommendations

The MDF7C-15P-2.54DSA(95) is the direct equivalent for the obsolete MDF7C-15P-2.54DSA(55). Both parts maintain identical electrical, mechanical, and environmental specifications within the MDF7 series. The substitute part carries active product status, ensuring continued availability and supply chain reliability. Both parts satisfy RoHS compliance requirements and carry equivalent regulatory classifications. Selection of the active-status substitute eliminates obsolescence risk while maintaining full functional and dimensional compatibility.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable? A: Yes. Both connectors share identical pitch (0.100"), position count (15), row configuration (1), and overall pin length (0.984"). They are designed for the same through-hole PCB footprint.

Q: What is the difference between the two part numbers? A: The primary difference is product status. MDF7C-15P-2.54DSA(55) is obsolete, while MDF7C-15P-2.54DSA(95) maintains active status. The suffix designation reflects packaging or manufacturing revision, but electrical and mechanical specifications remain identical.
