Engineering Selection Recommendations

The DF1BZ-15P-2.5DSA is the direct substitute for DF1B-15P-2.5DSA. Selection should be based on the following factors:

Product Status: The original DF1B-15P-2.5DSA is obsolete. The DF1BZ-15P-2.5DSA is in active production, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The DF1BZ-15P-2.5DSA is RoHS compliant, whereas the original part is RoHS non-compliant. For applications subject to RoHS regulations, the substitute is required. For legacy systems without RoHS requirements, both parts maintain identical electrical and mechanical specifications.

Certification & Standards: Both parts meet UL94 V-0 flammability requirements and carry identical ECCN and HTSUS classifications, confirming regulatory equivalence.

Physical & Electrical Compatibility: All critical dimensions, contact specifications, voltage ratings, and temperature ranges are identical, ensuring direct mechanical and electrical interchangeability in existing designs.

Frequently Asked Questions (FAQ)

Q: Can DF1BZ-15P-2.5DSA be used as a direct replacement for DF1B-15P-2.5DSA?

A: Yes. Both connectors share identical electrical ratings (250V), mechanical dimensions, contact geometry, pitch (2.50mm), and operating temperature range (-35°C to 85°C). The DF1BZ variant is the active production equivalent.

Q: What is the primary difference between these two parts?

A: The DF1B-15P-2.5DSA is obsolete, while DF1BZ-15P-2.5DSA is in active production. Additionally, DF1BZ-15P-2.5DSA is RoHS compliant, whereas DF1B-15P-2.5DSA is not.

Q: Are there packaging differences between these parts?

A: The DF1B-15P-2.5DSA packaging is not specified in the data. The DF1BZ-15P-2.5DSA is supplied in bulk packaging.

Q: Will the DF1BZ-15P-2.5DSA fit existing PCB designs using DF1B-15P-2.5DSA?

A: Yes. Both connectors have identical through-hole mounting specifications, insulation height (9.50mm), and mated stacking height (14mm), confirming PCB footprint compatibility.

Q: Are there any electrical performance differences?

A: No. Both parts maintain 250V voltage rating, identical contact materials (brass with tin finish), and equivalent electrical performance across the specified operating temperature range.

Q: Which part should be selected for new designs?

A: DF1BZ-15P-2.5DSA should be selected for new designs due to active production status and RoHS compliance.
