Parameter Comparison

Engineering Selection Recommendations

DF1BZ-6DP-2.5DS is the direct manufacturer equivalent offering active product status and ROHS3 compliance. This part maintains identical mechanical dimensions and contact geometry. The voltage rating of 150V is suitable for applications operating at or below this threshold. Selection of this part is appropriate for designs where the 150V rating satisfies system requirements and RoHS3 compliance is mandated.

DF1B-6DP-2.5DS(01) is the manufacturer-recommended replacement providing active product status, ROHS3 compliance, and the original 250V voltage rating. The gold contact finish on the mating surface provides enhanced corrosion resistance compared to the tin finish of the original part. This part is the preferred selection for new designs and production transitions where the original voltage specification must be maintained and superior contact durability is beneficial.

Both substitute parts are manufactured by Hirose Electric Co Ltd within the DF1B series and provide full mechanical and electrical interchangeability with the obsolete DF1B-6DP-2.5DS.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-6DP-2.5DS be used as a direct replacement for DF1B-6DP-2.5DS?

A: Yes. Both parts share identical mechanical dimensions, contact pitch, row spacing, mounting configuration, and fastening mechanism. The DF1BZ variant is an active product with ROHS3 compliance. The 150V voltage rating of the DF1BZ is suitable for applications operating at or below this specification. Verify your application voltage requirement before selection.

Q: What is the difference between DF1BZ-6DP-2.5DS and DF1B-6DP-2.5DS(01)?

A: Both are active, ROHS3-compliant alternatives. The primary differences are: DF1BZ-6DP-2.5DS has a 150V voltage rating with tin mating contact finish; DF1B-6DP-2.5DS(01) maintains the original 250V voltage rating with gold mating contact finish. Select DF1B-6DP-2.5DS(01) if your application requires 250V rating or enhanced contact durability through gold plating.

Q: Are the substitute parts compatible with existing PCB layouts designed for DF1B-6DP-2.5DS?

A: Yes. All substitute parts maintain identical through-hole mounting positions, contact spacing, and right-angle orientation. PCB layouts require no modification.

Q: What is the significance of the contact finish difference between tin and gold?

A: Both finishes provide adequate electrical conductivity and corrosion resistance for standard applications. Gold plating offers superior corrosion resistance and lower contact resistance in low-current applications. Tin plating is suitable for general-purpose applications. Selection depends on application environment and contact current requirements.

Q: Are there packaging differences between the substitute parts?

A: DF1BZ-6DP-2.5DS is supplied in bulk packaging. DF1B-6DP-2.5DS(01) is supplied in bulk packaging. Both are suitable for production assembly processes.

Q: Which substitute part should be selected for new designs?

A: DF1B-6DP-2.5DS(01) is the manufacturer-recommended replacement, offering active status, ROHS3 compliance, original 250V voltage rating, and enhanced contact durability through gold plating. This part is the preferred selection for new product development.
