Engineering Selection Recommendations

DF1BZ-30DP-2.5DS is suitable for applications where RoHS compliance is required. This part maintains identical mechanical and thermal specifications to the original DF1B-30DP-2.5DS while offering active product status and RoHS compliance. The voltage rating of 150V is lower than the original 250V specification; applications requiring 250V operation should not use this substitute.

DF1B-30DP-2.5DS(01) is the manufacturer-recommended replacement for the obsolete DF1B-30DP-2.5DS. This part maintains the original 250V voltage rating and RoHS compliance. The gold contact finish on the mating surface differs from the tin finish of the original part, providing enhanced corrosion resistance and contact reliability. This part is recommended as the primary substitute for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-30DP-2.5DS be used in place of DF1B-30DP-2.5DS in all applications?

A: DF1BZ-30DP-2.5DS is mechanically and thermally compatible with DF1B-30DP-2.5DS. However, the voltage rating differs: DF1BZ-30DP-2.5DS is rated for 150V while the original is rated for 250V. Applications operating at voltages above 150V require DF1B-30DP-2.5DS(01) instead.

Q: What is the difference between DF1B-30DP-2.5DS(01) and the original DF1B-30DP-2.5DS?

A: Both parts share identical mechanical dimensions, pitch specifications, mounting configuration, and 250V voltage rating. The primary differences are product status (active vs. obsolete), RoHS compliance (compliant vs. non-compliant), and contact finish (gold vs. tin on the mating surface). DF1B-30DP-2.5DS(01) is the manufacturer-recommended successor.

Q: Are these connectors backward compatible with existing mating connectors?

A: All three parts maintain identical pitch (0.098" / 2.50mm), row spacing, contact length, and shrouding specifications. They are mechanically compatible with the same mating connectors. Contact finish differences do not affect mechanical mating.

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

A: DF1B-30DP-2.5DS(01) is recommended for new designs. It offers active product status, RoHS compliance, and maintains the original 250V voltage rating with enhanced contact reliability through gold plating.

Q: What is the packaging difference between these parts?

A: DF1B-30DP-2.5DS original packaging is not specified. DF1BZ-30DP-2.5DS and DF1B-30DP-2.5DS(01) are supplied in bulk packaging.
