Engineering Selection Recommendations
The DF1BZ-2P-2.5DSA serves as the direct substitute for the obsolete DF1BZ-2P-2.5DSA(18). Selection of this substitute part is supported by the following factors:
- Product Status Alignment: The substitute part maintains active product status with Hirose Electric Co Ltd, ensuring continued availability and manufacturing support.
- Regulatory Compliance: The substitute part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
- Electrical Specifications: Voltage rating of 250V and operating temperature range of -35°C to 85°C provide equivalent electrical performance characteristics.
- Mechanical Compatibility: Identical pitch, position count, mounting type, and shrouding configuration ensure direct mechanical substitution without design modification.
- Material Certification: UL94 V-0 flammability rating provides equivalent safety performance for the insulation material.
Frequently Asked Questions (FAQ)
Q: Can the DF1BZ-2P-2.5DSA be used as a direct replacement for DF1BZ-2P-2.5DSA(18)?
A: Yes. Both parts share identical electrical and mechanical specifications including 2-position configuration, 2.5mm pitch, through-hole mounting, and push-pull fastening. The substitute part is the active equivalent.
Q: What is the significance of the "(18)" designation in the original part number?
A: The "(18)" suffix in DF1BZ-2P-2.5DSA(18) represents a specific manufacturing or packaging variant. The base part number DF1BZ-2P-2.5DSA without this suffix is the current active equivalent.
Q: Are there any differences in contact specifications between the two parts?
A: The substitute part specifies contact dimensions (mating length 0.177", post length 0.142", overall length 0.417"), contact shape (square), and contact finish (tin on brass). These specifications define the standard performance characteristics for this connector series.
Q: What compliance certifications apply to the substitute part?
A: The DF1BZ-2P-2.5DSA is ROHS3 compliant, REACH unaffected, and carries a UL94 V-0 flammability rating for the polyamide/nylon insulation material.
Q: Is the moisture sensitivity level different between the two parts?
A: Yes. The original part lists MSL as not applicable, while the substitute part specifies MSL 1 (unlimited). MSL 1 indicates no moisture sensitivity restrictions for storage and handling.
Q: What is the mated stacking height specification?
A: The mated stacking height is 14mm, which defines the vertical dimension when the connector is fully mated with its corresponding receptacle.
