Key Parameters

Substitute Part Grouping Explanation

The MDF7C-26DP-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 connector specifications: 26 positions, 0.100" (2.54mm) pitch, dual-row configuration
• Identical row spacing of 0.100" (2.54mm)
• Equivalent mounting method (through-hole solder termination)
• Matching contact finish (tin-plated)
• Identical electrical ratings and compliance certifications

The primary distinction is product status: MDF7C-26DP-2.54DSA(55) is obsolete, while MDF7C-26DP-2.54DSA(95) maintains active status with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The MDF7C-26DP-2.54DSA(95) is the direct substitute for the obsolete MDF7C-26DP-2.54DSA(55). Both components share identical mechanical and electrical specifications within the MDF7 series, ensuring pin-for-pin compatibility and functional equivalence in through-hole applications.

Selection of the active substitute is supported by:

• Maintained RoHS compliance across both parts
• Identical moisture sensitivity classification (MSL 1)
• Consistent ECCN and HTSUS coding
• Active product status with established supply chain availability
• Equivalent regulatory certifications and material specifications

The substitute part is suitable for direct replacement in existing designs without circuit modification or PCB redesign.

Frequently Asked Questions (FAQ)

Q: Are MDF7C-26DP-2.54DSA(55) and MDF7C-26DP-2.54DSA(95) mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (26), row configuration (2 rows), and through-hole mounting specifications. They are mechanically interchangeable on PCBs designed for either part number.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. MDF7C-26DP-2.54DSA(55) is obsolete, while MDF7C-26DP-2.54DSA(95) is active with current manufacturing and inventory support. The suffix designation (55 vs. 95) indicates different production batches or packaging configurations, but electrical and mechanical parameters remain equivalent.

Q: Can I use MDF7C-26DP-2.54DSA(95) as a replacement in existing assemblies?

A: Yes. The substitute part maintains full compatibility with designs originally specified for MDF7C-26DP-2.54DSA(55). No circuit redesign or PCB modification is required.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS compliance status, moisture sensitivity level (MSL 1), and regulatory classifications (ECCN EAR99, HTSUS 8536.69.4040).

Q: What packaging is available for the substitute part?

A: MDF7C-26DP-2.54DSA(95) is supplied in bag packaging, whereas packaging information for the original part was not specified in the technical data.
