Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-24DP-2.5DS is determined by the following critical parameters that must remain constant across all equivalent parts:

• Connector type: Header
• Number of positions: 24
• Number of rows: 2
• Pitch spacing: 0.098" (2.50mm)
• Row spacing: 0.098" (2.50mm)
• Mounting type: Through hole, right angle
• Shrouding configuration: Shrouded - 4 wall
• Contact type: Male pin
• Fastening type: Push-pull
• Termination method: Solder
• Operating temperature range: -35°C ~ 85°C
• Material flammability rating: UL94 V-0
• Insulation material: Polyamide (PA), Nylon

The identified substitute parts maintain these core electrical and mechanical parameters, ensuring functional compatibility in applications originally designed for the DF1B-24DP-2.5DS.

Parameter Comparison

Engineering Selection Recommendations

DF1BZ-24DP-2.5DS is an active-status direct substitute from the same DF1B series. This part maintains all critical mechanical and electrical parameters. The primary distinction is the voltage rating of 150V compared to the original 250V specification. This part is RoHS compliant, addressing regulatory requirements for new designs and procurement. Selection of this part is appropriate for applications where the 150V rating satisfies system voltage requirements.

DF1B-24DP-2.5DS(01) is the manufacturer-recommended active substitute, also from the DF1B series. This part maintains the original 250V voltage rating and all mechanical specifications. The contact finish differs, featuring gold plating on mating contacts instead of tin. This part is RoHS compliant and available in bulk packaging, making it suitable for production-volume applications. The gold contact finish provides enhanced corrosion resistance and contact reliability compared to tin plating.

Both substitute parts are active products with current manufacturing status, ensuring long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-24DP-2.5DS be used as a direct replacement for DF1B-24DP-2.5DS?

A: DF1BZ-24DP-2.5DS maintains all mechanical and mating parameters required for physical and functional compatibility. The voltage rating is 150V versus the original 250V. Selection depends on whether the application circuit operates within the 150V maximum rating. Both parts share identical connector geometry, pitch spacing, row configuration, and fastening mechanism.

Q: What is the difference between DF1B-24DP-2.5DS(01) and the original DF1B-24DP-2.5DS?

A: DF1B-24DP-2.5DS(01) maintains the 250V voltage rating and all mechanical specifications of the original part. The contact finish on mating surfaces is gold-plated rather than tin-plated. Both parts are electrically and mechanically compatible. The primary advantage of the (01) variant is active product status and RoHS compliance.

Q: Are there packaging differences between these substitute parts?

A: DF1B-24DP-2.5DS(01) is specified with bulk packaging, while packaging information for DF1BZ-24DP-2.5DS is not provided in the technical data. Packaging selection should be confirmed with the supplier based on procurement volume and handling requirements.

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

A: Selection between DF1BZ-24DP-2.5DS and DF1B-24DP-2.5DS(01) depends on voltage requirements. For applications requiring 250V rating, DF1B-24DP-2.5DS(01) is the appropriate choice. For applications with maximum 150V requirements, DF1BZ-24DP-2.5DS is suitable. Both parts are RoHS compliant and active products.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical connector type, position count, row configuration, pitch spacing, mounting orientation, shrouding design, and contact geometry. Physical board layout and mating connector compatibility are identical across all three parts.
