Key Parameters

Substitute Part Grouping Explanation

The substitute part DF1BZ-24DP-2.5DS is qualified as a direct equivalent based on the following critical parameters:

• Connector Series: Both parts belong to the DF1B series from Hirose Electric Co Ltd
• Position Count: Identical 24-position configuration
• Pitch Specification: Matching 0.098" (2.50mm) mating pitch and row spacing
• Mounting Configuration: Both feature through-hole, right-angle mounting
• Contact System: Identical male pin contact type with solder termination
• Mechanical Interface: Shrouded 4-wall design with push-pull fastening
• Electrical Ratings: Consistent 150V voltage rating

The primary distinction is product status: the substitute part DF1BZ-24DP-2.5DS is active and currently in production, whereas the original DF1BZ-24DP-2.5DS(29) is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The DF1BZ-24DP-2.5DS substitute part is the appropriate selection for applications currently using or requiring the DF1BZ-24DP-2.5DS(29). The substitute maintains full mechanical and electrical compatibility while offering the following advantages:

• Active Product Status: The substitute is in active production, ensuring long-term availability and supply chain stability
• RoHS Compliance: The substitute meets RoHS requirements, supporting regulatory compliance for new designs and manufacturing
• Moisture Sensitivity Classification: MSL 1 rating provides unlimited shelf life without moisture control requirements
• Identical Electrical Performance: 150V rating and operating temperature range (-35°C ~ 85°C) remain unchanged

No design modifications are required for migration from the obsolete part to the substitute.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-24DP-2.5DS be used as a direct replacement for DF1BZ-24DP-2.5DS(29)?

A: Yes. Both parts share identical mechanical dimensions, pitch specifications, contact configurations, and electrical ratings. The substitute is the current active equivalent.

Q: What is the significance of the "(29)" designation in the original part number?

A: The "(29)" suffix indicates a specific variant or revision level of the DF1BZ-24DP-2.5DS base part. The substitute part number without this suffix represents the current production version.

Q: Are there any compatibility concerns when switching to the substitute part?

A: No compatibility concerns exist. The substitute maintains the same 24-position, 2-row configuration with 2.5mm pitch, through-hole right-angle mounting, and solder termination. PCB layouts and mating connectors require no modification.

Q: What is the difference in moisture sensitivity between the two parts?

A: The original part lists MSL as "Not Applicable," while the substitute is classified as MSL 1 (Unlimited). MSL 1 provides superior shelf-life characteristics with no moisture control requirements during storage or handling.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The substitute is RoHS Compliant, meeting current environmental and regulatory requirements for electronic components in most markets.

Q: Are there any electrical performance differences?

A: No. Both parts maintain identical 150V voltage ratings and -35°C ~ 85°C operating temperature ranges.
