Engineering Selection Recommendations

The DF10-26S-2DSA(72) is the direct substitute for the obsolete DF10-26S-2DSA(62). Both connectors share identical mechanical and electrical specifications across all critical parameters: 26-position configuration, 0.079" pitch, through-hole mounting, push-pull fastening, 2A/250V ratings, and UL94 V-0 flammability compliance.

The DF10-26S-2DSA(72) offers the following advantages:

Active Product Status: Currently manufactured and supported by Hirose Electric Co Ltd, ensuring long-term availability and supply chain stability
Extended Operating Temperature Range: -55°C to 125°C versus -30°C to 85°C, providing broader environmental compatibility
RoHS Compliance: Meets RoHS requirements, supporting regulatory and environmental standards

Selection of the DF10-26S-2DSA(72) is appropriate for new designs, production continuity, and replacement applications where the original obsolete part is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the DF10-26S-2DSA(72) be used as a direct replacement for the DF10-26S-2DSA(62)?

A: Yes. Both connectors are mechanically and electrically equivalent across all specified parameters. The DF10-26S-2DSA(72) is the active production equivalent of the obsolete DF10-26S-2DSA(62).

Q: What are the key differences between these two parts?

A: The primary differences are product status and operating temperature range. The DF10-26S-2DSA(72) is an active product with an extended operating temperature range of -55°C to 125°C compared to -30°C to 85°C for the obsolete DF10-26S-2DSA(62). The DF10-26S-2DSA(72) also carries RoHS compliance certification.

Q: Are there any packaging differences?

A: The DF10-26S-2DSA(62) packaging is unspecified in the available data. The DF10-26S-2DSA(72) is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Will the DF10-26S-2DSA(72) work in applications designed for the DF10-26S-2DSA(62)?

A: Yes. The connectors are pin-compatible and functionally equivalent. The expanded operating temperature range of the substitute part provides additional environmental margin without compromising compatibility.

Q: What is the contact material difference, and does it affect substitution?

A: The DF10-26S-2DSA(62) uses phosphor bronze contacts, while the DF10-26S-2DSA(72) uses copper contacts. Both materials are suitable for the specified electrical ratings and mating surface gold plating. This difference does not affect functional substitution.

Q: Are both parts compliant with the same standards?

A: Both connectors meet UL94 V-0 flammability requirements. The DF10-26S-2DSA(72) additionally carries RoHS compliance certification. Verify any additional regulatory requirements specific to your application.
