Engineering Selection Recommendations

Both DF22R-4P-7.92DSA(23) and DF22R-4P-7.92DSA(53) are active product alternatives to the obsolete DF22R-4P-7.92DSA(05). Selection between these substitutes is based on compliance and product status considerations:

DF22R-4P-7.92DSA(23) is an active product with RoHS compliance status not specified in available documentation. This part features a rectangular contact shape and operates across an extended temperature range of -55°C to 85°C with gold-plated mating contacts.

DF22R-4P-7.92DSA(53) is an active product with ROHS3 compliance certification and REACH unaffected status. This part maintains the square contact shape of the original DF22R-4P-7.92DSA(05), operates across an extended temperature range of -55°C to 85°C, and includes both board guide and board lock features. Gold plating is applied to both mating and post contacts.

Frequently Asked Questions (FAQ)

Q: Can DF22R-4P-7.92DSA(23) and DF22R-4P-7.92DSA(53) be used interchangeably with DF22R-4P-7.92DSA(05)?

A: Both parts maintain the critical electrical and mechanical parameters required for functional compatibility: 4-position configuration, 0.312" (7.92mm) pitch, through-hole mounting, shrouded 4-wall design, 1000V voltage rating, and UL94 V-0 flammability rating. Physical mounting and electrical performance are compatible.

Q: What are the differences in contact finish between these parts?

A: The original DF22R-4P-7.92DSA(05) uses tin-copper plating on mating contacts. Both substitutes use gold plating on mating contacts. DF22R-4P-7.92DSA(53) additionally applies gold plating to post contacts. Gold plating provides enhanced corrosion resistance compared to tin-copper.

Q: How do the operating temperature ranges differ?

A: The original part operates from -35°C to 85°C. Both substitute parts extend the lower temperature limit to -55°C, providing a wider operating range suitable for applications requiring enhanced cold-temperature performance.

Q: What is the significance of the contact shape difference?

A: The original DF22R-4P-7.92DSA(05) and DF22R-4P-7.92DSA(53) feature square contact shapes. The DF22R-4P-7.92DSA(23) uses rectangular contacts. Both geometries are compatible with standard mating connectors designed for the DF22 series 0.312" (7.92mm) pitch.

Q: Which substitute part is recommended for new designs?

A: DF22R-4P-7.92DSA(53) is recommended for new designs due to active product status, ROHS3 compliance certification, REACH unaffected status, and inclusion of board guide and board lock features for enhanced mechanical stability.

Q: Are there packaging differences between these parts?

A: The original DF22R-4P-7.92DSA(05) packaging is not specified. DF22R-4P-7.92DSA(23) packaging is not specified. DF22R-4P-7.92DSA(53) is supplied in bag packaging.
