Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF1BZ-24DP-2.5DSA(29) is determined by strict equivalence across the following critical parameters:

• Connector Series & Base Number: Both parts must belong to the DF1B series family
• Position Count & Row Configuration: 24 positions in 2-row arrangement
• Mating Pitch: 0.098" (2.50mm) center-to-center spacing
• Connector Type & Contact Type: Header with male pins for board-to-cable/wire applications
• Mounting & Termination: Through-hole solder termination
• Shrouding Configuration: Shrouded 4-wall design with keying slot
• Electrical Ratings: 250V voltage rating and operating temperature range -35°C ~ 85°C
• Material & Compliance: Polyamide (PA) nylon insulation, UL94 V-0 flammability rating

The substitute part DF1BZ-24DP-2.5DSA meets all these criteria and is the direct equivalent for the obsolete variant.

Parameter Comparison

Engineering Selection Recommendations

The DF1BZ-24DP-2.5DSA is the direct active substitute for the obsolete DF1BZ-24DP-2.5DSA(29). Selection of this substitute is supported by:

• Product Status Alignment: The substitute maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The active substitute carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements
• Electrical & Mechanical Equivalence: All critical connector parameters—position count, pitch, mounting type, shrouding configuration, and electrical ratings—are identical
• Certification & Standards: UL94 V-0 flammability rating and MSL 1 classification confirm suitability for standard industrial and commercial applications
• Interchangeability: The substitute is a direct pin-for-pin and form-factor equivalent, requiring no design modifications for integration into existing PCB layouts or cable assemblies

Frequently Asked Questions (FAQ)

Q: Is the DF1BZ-24DP-2.5DSA a direct replacement for the DF1BZ-24DP-2.5DSA(29)?

A: Yes. The DF1BZ-24DP-2.5DSA is the active production equivalent. Both parts share identical connector type, position count (24), row configuration (2 rows), mating pitch (2.5mm), shrouding design, and electrical ratings. The substitute is pin-for-pin and form-factor compatible with no design changes required.

Q: Why is the original part marked as obsolete?

A: The DF1BZ-24DP-2.5DSA(29) has been discontinued by Hirose Electric Co Ltd. The active substitute DF1BZ-24DP-2.5DSA represents the current production offering within the DF1B series and is recommended for all new designs and legacy system maintenance.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in connector type (header), contact type (male pin), position count (24), row arrangement (2 rows), mating pitch (2.5mm), row spacing (2.5mm), mounting method (through-hole), termination type (solder), shrouding configuration (4-wall shrouded), and electrical ratings (250V, -35°C ~ 85°C operating range).

Q: Does the substitute meet current regulatory requirements?

A: Yes. The DF1BZ-24DP-2.5DSA is ROHS3 compliant, REACH unaffected, and carries UL94 V-0 flammability certification, meeting current environmental and safety standards for industrial and commercial applications.

Q: What is the packaging configuration for the substitute part?

A: The DF1BZ-24DP-2.5DSA is supplied in bulk packaging, with 1228 pieces available in new original stock.

Q: Are there any differences in contact materials or finishes between the obsolete and substitute parts?

A: The substitute specifies brass contact material with tin finish on both mating and post surfaces. These specifications represent standard Hirose DF1B series construction and ensure reliable electrical performance and corrosion resistance.

Q: What is the moisture sensitivity level (MSL) of the substitute part?

A: The DF1BZ-24DP-2.5DSA carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
