Engineering Selection Recommendations

DF1BZ-10P-2.5DS is an active direct equivalent suitable for applications where RoHS compliance is required. This part maintains all mechanical and electrical compatibility with the obsolete DF1B-10P-2.5DS. The voltage rating is reduced to 150V; applications requiring 250V operation must use DF1B-10P-2.5DS(01). Contact finish is tin on both mating and post surfaces.

DF1B-10P-2.5DS(01) is the manufacturer-recommended substitute for new designs and production. This part is active and ROHS3 compliant, maintaining the 250V voltage rating of the original part. The contact finish on the mating surface is gold with 8.00µin (0.203µm) thickness, providing enhanced corrosion resistance compared to tin plating. This part is preferred for applications requiring maximum compliance certifications and superior contact durability.

Both substitutes are available in bulk packaging and maintain full mechanical interchangeability with the original DF1B-10P-2.5DS connector header.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-10P-2.5DS be used in place of DF1B-10P-2.5DS in all applications?

A: DF1BZ-10P-2.5DS is mechanically and electrically compatible for applications operating at 150V or below. Applications requiring 250V operation must use DF1B-10P-2.5DS(01). Both parts share identical connector geometry, pitch, mounting type, and contact configuration.

Q: What is the difference between tin and gold contact finishes?

A: DF1B-10P-2.5DS and DF1BZ-10P-2.5DS use tin contact finish on mating surfaces. DF1B-10P-2.5DS(01) uses gold contact finish (8.00µin thickness) on mating surfaces, providing improved corrosion resistance and contact reliability in demanding environments.

Q: Are all three parts through-hole, right-angle connectors?

A: Yes. All three parts are through-hole, right-angle mounted rectangular connector headers with identical shrouding (4-wall), fastening type (push-pull), and termination method (solder).

Q: What is the significance of RoHS compliance status?

A: DF1B-10P-2.5DS is RoHS non-compliant. DF1BZ-10P-2.5DS is RoHS compliant. DF1B-10P-2.5DS(01) is ROHS3 compliant. Selection depends on regulatory requirements for the end application and target markets.

Q: Do all parts have the same operating temperature range?

A: Yes. All three parts operate across -35°C to 85°C, maintaining identical thermal performance specifications.

Q: What packaging options are available?

A: DF1B-10P-2.5DS original part packaging is not specified. DF1BZ-10P-2.5DS and DF1B-10P-2.5DS(01) are supplied in bulk packaging.
