Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF1BZ-8P-2.5DSA(18) is determined by the following critical parameters that must remain constant:

• Base Product Series: DF1B family maintains mechanical and electrical compatibility
• Number of Positions: 8-position configuration
• Mating Pitch: 0.098" (2.50mm) spacing
• Connector Type: Header with male pin contacts
• Mounting Method: Through hole PCB mounting
• Application Style: Board to cable/wire interconnection
• Contact Material and Finish: Brass with tin plating

The substitute part DF1BZ-8P-2.5DSA shares the identical base product number (DF1BZ) and all critical electrical and mechanical parameters, making it a direct functional equivalent. The primary distinction is product status: the substitute is active in production with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The DF1BZ-8P-2.5DSA (active production variant) is the direct substitute for the obsolete DF1BZ-8P-2.5DSA(18). Both parts share identical base product designation and core electrical/mechanical specifications. The active variant carries current compliance certifications including ROHS3 and REACH Unaffected status, ensuring regulatory alignment with modern manufacturing standards. The active part maintains full backward compatibility with existing PCB designs and mating connectors specified for the DF1BZ series at 2.5mm pitch with 8 positions. Selection of the active production part eliminates obsolescence risk and provides assured long-term supply availability.

Frequently Asked Questions (FAQ)

Q: Are the DF1BZ-8P-2.5DSA(18) and DF1BZ-8P-2.5DSA mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including 8-position configuration, 2.5mm mating pitch, through-hole mounting, and board-to-cable/wire application style. PCB footprints and mating connector interfaces are identical.

Q: What is the significance of the "(18)" designation in the obsolete part number?

A: The "(18)" suffix in DF1BZ-8P-2.5DSA(18) represents a specific manufacturing or packaging variant. The active substitute DF1BZ-8P-2.5DSA omits this suffix, indicating it is the current production standard.

Q: Does the active substitute meet current regulatory requirements?

A: Yes. The DF1BZ-8P-2.5DSA is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Can existing designs using the obsolete part be directly updated to the active substitute?

A: Yes. The active substitute maintains full electrical and mechanical compatibility with designs specified for the DF1BZ-8P-2.5DSA(18). No design modifications are required.

Q: What is the operating temperature range for the substitute part?

A: The active substitute operates across -35°C to 85°C, suitable for standard industrial and commercial applications.

Q: Is there a difference in packaging between the obsolete and active variants?

A: The obsolete part lists packaging as unspecified. The active substitute is supplied in bulk packaging with confirmed inventory availability of 2000 pieces.
