Engineering Selection Recommendations

Both DF22R-2P-7.92DSA(23) and DF22R-2P-7.92DSA(53) are active product alternatives to the obsolete DF22R-2P-7.92DSA(05).

DF22R-2P-7.92DSA(23) provides an active status replacement with gold contact finish and extended operating temperature range (-55°C to 85°C). This part maintains RoHS compliance and meets all core electrical specifications of the original component.

DF22R-2P-7.92DSA(53) offers the most comprehensive upgrade path, featuring ROHS3 compliance, gold contact finish on both mating and post surfaces, and extended operating temperature range. This part includes board guide and board lock features and is available in bag packaging. The contact finish thickness specification (8.00µin / 0.203µm) is documented for both mating and post surfaces.

Selection between these alternatives depends on specific application requirements regarding contact finish specifications, temperature range demands, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can DF22R-2P-7.92DSA(23) and DF22R-2P-7.92DSA(53) be used interchangeably with DF22R-2P-7.92DSA(05)?

A: Both parts maintain the same connector type, contact type, position count, pitch spacing, mounting method, and shrouding configuration. The primary differences are contact finish material (gold versus tin-copper), operating temperature range, and compliance certifications. Mechanical and electrical compatibility is established for board-to-cable/wire applications.

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

A: The contact finish affects corrosion resistance and contact reliability. Gold plating provides enhanced protection against oxidation and is suitable for applications requiring extended shelf life or exposure to corrosive environments.

Q: Does the extended operating temperature range of the substitute parts affect compatibility?

A: The substitute parts support a wider operating temperature range (-55°C to 85°C versus -35°C to 85°C). This represents an enhancement and does not create compatibility issues for applications within the original temperature specification.

Q: Are there packaging differences between the substitute parts?

A: DF22R-2P-7.92DSA(05) and DF22R-2P-7.92DSA(23) do not specify packaging. DF22R-2P-7.92DSA(53) is supplied in bag packaging.

Q: What compliance certifications apply to each part?

A: DF22R-2P-7.92DSA(05) is RoHS Compliant. DF22R-2P-7.92DSA(23) is RoHS Compliant. DF22R-2P-7.92DSA(53) is ROHS3 Compliant and REACH Unaffected.
