Engineering Selection Recommendations

The MDF6-6DP-3.5DS(23) is the direct substitute for the obsolete MDF6-6DP-3.5DS(05). Selection is based on the following factors:

Product Status: The MDF6-6DP-3.5DS(23) maintains active product status with Hirose Electric Co Ltd, ensuring ongoing availability and manufacturing support compared to the obsolete MDF6-6DP-3.5DS(05).

Compliance & Certifications: Both parts maintain identical UL94 V-0 flammability ratings and equivalent RoHS compliance (RoHS Compliant vs. ROHS3 Compliant). The substitute meets current regulatory requirements.

Mechanical & Electrical Compatibility: All critical parameters—connector series, pitch, position configuration, mounting type, shrouding, and voltage rating—are identical or within acceptable tolerances. The contact mating length variance (5.59mm vs. 5.60mm) is negligible for functional compatibility.

Contact Finish: The substitute features tin finish on mating contacts compared to tin-copper on the original. Both finishes provide equivalent electrical performance and corrosion resistance for this application class.

Frequently Asked Questions (FAQ)

Q: Can MDF6-6DP-3.5DS(23) be used as a direct replacement for MDF6-6DP-3.5DS(05)?

A: Yes. Both connectors share identical mechanical dimensions, electrical ratings, and mounting specifications. The substitute is functionally equivalent and maintains the same PCB footprint and mating interface.

Q: What is the difference between the contact finishes?

A: The original part features tin-copper plating, while the substitute uses tin plating. Both provide equivalent electrical conductivity and corrosion resistance for board-to-cable applications in the specified operating temperature range.

Q: Are there packaging differences?

A: The original part has unspecified packaging, while the substitute is supplied in bag packaging. This does not affect connector functionality or performance.

Q: Does the substitute meet current compliance standards?

A: Yes. The MDF6-6DP-3.5DS(23) is ROHS3 compliant and maintains UL94 V-0 flammability rating, meeting current regulatory requirements.

Q: What is the inventory status of the substitute?

A: The MDF6-6DP-3.5DS(23) has 956 pieces in stock as new original inventory, providing immediate availability for production and design applications.
