Engineering Selection Recommendations

The DF1EC-15P-2.5DSA(05) is the direct equivalent substitute for the obsolete DF1EC-15P-2.5DSA. Both parts maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, contact configuration, current rating, and operating temperature range.

The primary distinction between the two parts is product status and regulatory compliance. The DF1EC-15P-2.5DSA(05) is currently active in production with RoHS compliance certification, whereas the original part is obsolete and RoHS non-compliant. For new designs or production continuity, the DF1EC-15P-2.5DSA(05) is the appropriate selection. Both parts share identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Are the DF1EC-15P-2.5DSA and DF1EC-15P-2.5DSA(05) mechanically interchangeable?

A: Yes. Both connectors feature identical mounting type (through-hole), shrouding configuration (4-wall), contact dimensions, insulation height, and mated stacking heights. They are direct mechanical substitutes.

Q: What is the significance of the "(05)" designation in the part number?

A: The "(05)" suffix indicates a revision or variant designation assigned by Hirose Electric. In this case, it denotes the active production version with updated compliance status.

Q: Can the DF1EC-15P-2.5DSA(05) be used in applications originally designed for the DF1EC-15P-2.5DSA?

A: Yes. The electrical and mechanical parameters are identical. The substitute part maintains the same 3A current rating, -35°C to 85°C operating temperature range, and all dimensional specifications.

Q: What are the key parameters that define substitution eligibility for this connector?

A: Substitution requires equivalence in connector type (header), series (DF1E), position count (15), mating pitch (2.50mm), contact type (male pin), mounting method (through-hole), shrouding (4-wall), termination (solder), and electrical ratings (3A, -35°C to 85°C).

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and supply chain consideration, not a functional electrical or mechanical requirement. The DF1EC-15P-2.5DSA(05) provides improved compliance status while maintaining complete functional equivalence.

Q: Are there any differences in contact finish or material composition?

A: No. Both parts use brass contacts with tin plating and polyamide insulation material. Contact finish thickness and material specifications are identical.
