DF1B-16DP-2.5DS Equivalent & Substitute Parts

Part Overview

The DF1B-16DP-2.5DS is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This connector features 16 positions arranged in 2 rows with 0.098" (2.50mm) pitch spacing and push-pull fastening. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF1B-16DP-2.5DS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type: Header
• Number of positions: 16
• Number of rows: 2
• Pitch spacing: 0.098" (2.50mm)
• Row spacing: 0.098" (2.50mm)
• Mounting type: Through hole, right angle
• Contact type: Male pin
• Shrouding: Shrouded - 4 wall
• Fastening type: Push-pull
• Operating temperature range: -35°C ~ 85°C
• Material flammability rating: UL94 V-0
• Insulation material: Polyamide (PA), Nylon
• Contact material: Brass
• Keying slot feature: Present

Substitute parts must maintain these parameters to ensure mechanical fit, electrical performance, and safety compliance in the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

DF1BZ-16DP-2.5DS is an active equivalent substitute with full mechanical and electrical compatibility. This part maintains all critical connector parameters and operates within the same temperature range. The primary distinction is the reduced voltage rating of 150V compared to the original 250V specification. This part carries RoHS compliance status and is available in tray packaging. Selection of this substitute is appropriate for applications where the 150V voltage rating meets circuit requirements.

DF1B-16DP-2.5DS(01) is the manufacturer-recommended active substitute. This part maintains all critical connector parameters including the original 250V voltage rating and operating temperature range. The contact finish differs, specified as gold with 8.00µin (0.203µm) thickness on mating surfaces, compared to tin finish on the original part. This part carries RoHS compliance status and is available in bulk packaging with the highest current inventory level. This substitute is recommended for direct replacement applications requiring voltage rating equivalence.

Both substitute parts are manufactured by Hirose Electric Co Ltd within the DF1B series and maintain the same mechanical interface, electrical performance characteristics, and safety certifications as the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-16DP-2.5DS be used as a direct replacement for DF1B-16DP-2.5DS?

A: DF1BZ-16DP-2.5DS maintains mechanical compatibility and all critical connector parameters. The voltage rating is reduced to 150V. Selection depends on circuit voltage requirements. If the application operates at or below 150V, this substitute is mechanically and electrically compatible.

Q: What is the difference between DF1B-16DP-2.5DS(01) and the original part?

A: DF1B-16DP-2.5DS(01) maintains identical mechanical dimensions, position count, pitch spacing, mounting type, and voltage rating. The contact finish differs: the substitute uses gold plating at 8.00µin thickness on mating surfaces, while the original uses tin finish. Both finishes are compatible with standard PCB pad materials.

Q: Are there packaging differences between the substitute parts?

A: Yes. DF1BZ-16DP-2.5DS is supplied in tray packaging. DF1B-16DP-2.5DS(01) is supplied in bulk packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Do the substitute parts meet RoHS compliance?

A: Both DF1BZ-16DP-2.5DS and DF1B-16DP-2.5DS(01) are RoHS compliant. The original DF1B-16DP-2.5DS is RoHS non-compliant. Selection of either substitute satisfies RoHS requirements for new designs and production.

Q: What is the mechanical fit compatibility between these parts?

A: All three parts share identical mechanical specifications: 16 positions in 2 rows, 0.098" (2.50mm) pitch, through-hole right-angle mounting, shrouded 4-wall design, and push-pull fastening. PCB footprints and mating connector interfaces are identical.

Q: Can these parts be intermixed in the same assembly?

A: Yes. All three parts maintain identical mechanical interfaces and contact geometry. They can be used interchangeably in the same assembly provided voltage and compliance requirements are met for each application.
