Key Parameters

Substitute Part Grouping Explanation

The substitute part DF1BZ-7P-2.5DSA is functionally equivalent to the obsolete DF1BZ-7P-2.5DSA(21) based on the following critical parameters that determine substitutability:

• Base Product Series: Both parts share the DF1BZ base product number, indicating they belong to the same connector family
• Position Count: Both feature 7 positions
• Mating Pitch: Both maintain 0.098" (2.50mm) pitch spacing
• Connector Type & Contact Configuration: Both are shrouded headers with male pins for board-to-cable/wire applications
• Mounting & Termination: Both use through-hole mounting with solder termination
• Fastening Mechanism: Both employ push-pull fastening
• Electrical Ratings: Both are rated for 250V operation
• Material & Compliance: Both use polyamide (PA) nylon insulation with UL94 V-0 flammability rating

The primary distinction is product status: the original part is obsolete, while the substitute is active in production with improved availability.

Engineering Selection Recommendations

The DF1BZ-7P-2.5DSA serves as the direct substitute for the obsolete DF1BZ-7P-2.5DSA(21). Selection is based on the following engineering criteria:

• Product Status Alignment: The substitute part is in active production status, ensuring long-term supply chain viability and manufacturing support
• Regulatory Compliance: The active substitute carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements
• Electrical & Mechanical Compatibility: All critical electrical parameters (voltage rating, contact material, termination method) and mechanical specifications (pitch, position count, mounting type, shrouding) are identical
• Thermal Performance: Both parts operate across the same temperature range (-35°C ~ 85°C), ensuring thermal compatibility in existing designs
• Certification Maintenance: Both parts maintain UL94 V-0 flammability rating, preserving safety certifications in applications requiring this standard

The substitute part is suitable for direct replacement in new designs and legacy system support without design modification.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-7P-2.5DSA be used as a direct replacement for DF1BZ-7P-2.5DSA(21)?

A: Yes. Both parts share identical electrical and mechanical specifications including 7-position configuration, 2.5mm pitch, through-hole mounting, solder termination, and push-pull fastening. The substitute is the active production equivalent of the obsolete part.

Q: What is the significance of the "(21)" designation in the original part number?

A: The "(21)" suffix in DF1BZ-7P-2.5DSA(21) represents a specific manufacturing or packaging variant. The base part DF1BZ-7P-2.5DSA without this suffix is the current active production version.

Q: Are there any compliance differences between the two parts?

A: The active substitute carries explicit ROHS3 compliance and REACH unaffected certification, while the obsolete part does not specify these certifications. Both maintain UL94 V-0 flammability rating and operate within identical electrical and thermal parameters.

Q: What is the Moisture Sensitivity Level (MSL) difference?

A: The obsolete part lists MSL as Not Applicable, while the active substitute is rated MSL 1 (Unlimited). MSL 1 indicates the component has unlimited shelf life without moisture control, representing improved handling characteristics.

Q: Are the physical dimensions and mating interfaces identical?

A: Yes. Both parts feature identical shrouded 4-wall design, 7-position configuration at 2.5mm pitch, and board-to-cable/wire connection style. PCB footprints and mating connector interfaces are compatible.

Q: What inventory status should be considered for procurement?

A: The active substitute DF1BZ-7P-2.5DSA has 1469 pieces in stock, providing reliable availability. The obsolete part has limited remaining inventory (932 pieces) and should not be specified for new designs.
