Parameter Comparison

Engineering Selection Recommendations

The MDF6-8DP-3.5DS(23) is the direct substitute for the obsolete MDF6-8DP-3.5DS(05). Both parts are manufactured by Hirose Electric Co Ltd within the MDF6 series and share identical mechanical and electrical specifications for all critical mating and mounting parameters.

Compliance Status: The MDF6-8DP-3.5DS(23) carries ROHS3 Compliant certification, representing an updated compliance standard compared to the RoHS Compliant status of the original part. Both parts maintain UL94 V-0 flammability rating and MSL 1 classification.

Availability: The MDF6-8DP-3.5DS(23) is classified as Active, ensuring continued manufacturing and supply chain availability. The original MDF6-8DP-3.5DS(05) is obsolete with limited remaining inventory.

Operating Temperature Range: The substitute part operates across -30°C to 85°C, compared to the original -35°C to 85°C range. This represents a 5°C reduction in the lower temperature limit and is acceptable for most industrial and commercial applications.

Contact Finish: The substitute part features Tin contact finish on both mating and post surfaces, compared to the original Tin-Copper mating finish. Both finishes provide equivalent electrical performance and corrosion resistance for the specified voltage and current applications.

Frequently Asked Questions (FAQ)

Q: Can MDF6-8DP-3.5DS(23) be used as a direct replacement for MDF6-8DP-3.5DS(05)?

A: Yes. Both connectors share identical pitch (3.50mm), position count (8), row configuration (2 rows), mounting type (through-hole right-angle), and shrouding design. Mechanical and electrical compatibility is confirmed across all critical parameters.

Q: What is the difference in operating temperature range?

A: The MDF6-8DP-3.5DS(05) operates from -35°C to 85°C, while the MDF6-8DP-3.5DS(23) operates from -30°C to 85°C. The substitute part has a 5°C higher minimum operating temperature. Applications requiring operation below -30°C must evaluate this specification against system requirements.

Q: Are there differences in contact finish?

A: The original part features Tin-Copper mating contact finish, while the substitute features Tin finish on both mating and post surfaces. Both finishes provide equivalent electrical conductivity and corrosion resistance for the 300V rating and specified applications.

Q: What is the packaging difference?

A: The MDF6-8DP-3.5DS(05) packaging is not specified. The MDF6-8DP-3.5DS(23) is supplied in Bag packaging. Confirm packaging requirements with procurement specifications.

Q: Are both parts RoHS compliant?

A: Yes. The MDF6-8DP-3.5DS(05) is RoHS Compliant. The MDF6-8DP-3.5DS(23) is ROHS3 Compliant, representing an updated regulatory standard. Both meet RoHS requirements.

Q: What is the contact length difference?

A: The mating contact length differs by 0.01mm (5.59mm versus 5.60mm), which is within normal manufacturing tolerance and does not affect functional compatibility.
