Engineering Selection Recommendations

Both substitute parts maintain full mechanical and electrical compatibility with the original DF1B-14DP-2.5DS design. Selection between alternatives should be based on the following factors:

DF1BZ-14DP-2.5DS: This part is actively manufactured and ROHS3 compliant, making it suitable for new designs and applications requiring RoHS certification. The voltage rating is 150V, which is lower than the original specification. This part is appropriate for applications where the 150V rating is sufficient and RoHS compliance is required.

DF1B-14DP-2.5DS(01): This part is actively manufactured and RoHS compliant with a 250V voltage rating matching the original specification. The contact finish on the mating surface is gold rather than tin, providing enhanced corrosion resistance and contact reliability. This part is recommended for applications requiring the full 250V rating and improved contact durability.

Both substitute parts are actively produced by Hirose Electric Co Ltd, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-14DP-2.5DS be used as a direct replacement for DF1B-14DP-2.5DS?

A: DF1BZ-14DP-2.5DS maintains all critical mechanical parameters and connector geometry. However, the voltage rating is 150V compared to the original 250V. Direct substitution is valid only if the application operates at or below 150V.

Q: What is the difference between the two substitute parts?

A: Both maintain identical mechanical specifications and connector geometry. The primary differences are: DF1BZ-14DP-2.5DS has a 150V voltage rating with tin mating contact finish; DF1B-14DP-2.5DS(01) has a 250V voltage rating with gold mating contact finish. The gold finish provides superior corrosion resistance.

Q: Are the substitute parts compatible with existing mating connectors designed for DF1B-14DP-2.5DS?

A: Yes. Both substitute parts maintain identical pitch spacing (0.098" / 2.50mm), row spacing, contact geometry, and shrouding configuration, ensuring full compatibility with existing mating connectors.

Q: What is the significance of the RoHS compliance difference?

A: The original DF1B-14DP-2.5DS is RoHS non-compliant. Both substitute parts are RoHS compliant, meeting current environmental and regulatory requirements for new product designs and applications subject to RoHS directives.

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

A: Selection depends on voltage requirements. For applications requiring 250V operation, DF1B-14DP-2.5DS(01) is recommended due to matching voltage rating and gold contact finish. For applications operating at 150V or below, DF1BZ-14DP-2.5DS is suitable and offers ROHS3 compliance.

Q: Are there packaging differences between the parts?

A: The original part packaging is not specified. Both substitute parts are supplied in bulk packaging, which is standard for production quantities.
