Engineering Selection Recommendations

Both DF22R-5P-7.92DSA(23) and DF22R-5P-7.92DSA(53) are active production parts suitable for replacing the obsolete DF22R-5P-7.92DSA(05).

DF22R-5P-7.92DSA(53) is the preferred substitute. It maintains identical contact geometry (square shape), contact length specifications, and includes board guide and board lock features. This part carries ROHS3 Compliant certification and REACH Unaffected status, providing enhanced regulatory compliance for new designs and long-term supply chain stability.

DF22R-5P-7.92DSA(23) serves as an alternative substitute with active product status and RoHS Compliant certification. The primary difference is rectangular contact shape versus the original square geometry, which may affect mating force characteristics and contact retention in specific applications.

Both substitutes feature gold contact finish on mating surfaces, providing superior corrosion resistance compared to the original tin-copper finish. Both support the full -55°C to 85°C operating temperature range, exceeding the original -35°C to 85°C specification.

Frequently Asked Questions (FAQ)

Q: Can DF22R-5P-7.92DSA(23) and DF22R-5P-7.92DSA(53) be used interchangeably with the original DF22R-5P-7.92DSA(05)?

A: Both parts maintain identical electrical and mechanical specifications for pitch, position count, voltage rating, and mounting configuration. Physical compatibility is confirmed. The primary differences are contact finish material (gold versus tin-copper) and contact shape geometry (rectangular versus square in the case of DF22R-5P-7.92DSA(23)). Verify mating connector compatibility before implementation.

Q: What is the significance of the contact finish change from tin-copper to gold?

A: Gold plating provides superior corrosion resistance and improved contact reliability over extended service life. This upgrade is beneficial for applications requiring high reliability or exposure to corrosive environments. No functional incompatibility exists with existing mating connectors.

Q: Why does DF22R-5P-7.92DSA(53) have different contact shape geometry?

A: The square contact shape in DF22R-5P-7.92DSA(53) matches the original part specification. DF22R-5P-7.92DSA(23) uses rectangular contacts, which may result in different mating force and contact retention characteristics. Verify compatibility with existing mating connectors before selection.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents the current regulatory standard with expanded substance restrictions. Both certifications indicate compliance with hazardous substance limitations. ROHS3 Compliant status in DF22R-5P-7.92DSA(53) ensures alignment with current and future regulatory requirements.

Q: Are there inventory considerations for these substitute parts?

A: DF22R-5P-7.92DSA(05) is obsolete with 698 pieces in stock. DF22R-5P-7.92DSA(23) has 785 pieces available, and DF22R-5P-7.92DSA(53) has 715 pieces available. Both active substitutes offer adequate inventory for current procurement needs.

Q: What is the operating temperature range difference?

A: The original part operates from -35°C to 85°C. Both substitutes extend the lower temperature limit to -55°C, providing enhanced performance in cold environment applications. The upper temperature limit remains unchanged at 85°C.
