Engineering Selection Recommendations

Both DF22-4P-7.92DSA(23) and DF22-4P-7.92DSA(53) provide full functional equivalence to the obsolete DF22-4P-7.92DSA(05) across all critical electrical and mechanical parameters.

DF22-4P-7.92DSA(23) is the primary active substitute, maintaining identical specifications with current product availability. This part is recommended for new designs and standard replacement applications.

DF22-4P-7.92DSA(53) offers an alternative with gold contact finish on both mating and post surfaces, providing enhanced corrosion resistance. This variant includes ROHS3 compliance certification and is packaged in bag format. Selection of this variant is appropriate when superior contact durability or specific compliance documentation is required.

Both substitutes are manufactured by Hirose Electric Co Ltd within the same EnerBee™ DF22 series, ensuring design continuity and interchangeability with existing connector systems.

Frequently Asked Questions (FAQ)

Q: Can DF22-4P-7.92DSA(23) and DF22-4P-7.92DSA(53) be used interchangeably with the obsolete DF22-4P-7.92DSA(05)?

A: Yes. Both substitutes maintain identical position count, pitch spacing, mounting type, electrical ratings, and mechanical dimensions. The primary difference is contact finish specification, which does not affect functional compatibility in standard applications.

Q: What is the significance of the contact finish difference between the three parts?

A: The DF22-4P-7.92DSA(05) features tin-copper contact finish, while DF22-4P-7.92DSA(23) does not specify finish detail, and DF22-4P-7.92DSA(53) uses gold finish. Contact finish affects corrosion resistance and long-term contact reliability. Gold-plated contacts provide superior performance in high-reliability or harsh environment applications.

Q: Are there packaging differences between the substitute parts?

A: DF22-4P-7.92DSA(23) packaging is not specified in available documentation. DF22-4P-7.92DSA(53) is supplied in bag packaging. Packaging differences do not affect connector performance or compatibility.

Q: Which substitute should be selected for new production designs?

A: DF22-4P-7.92DSA(23) is the recommended choice for new designs, as it maintains active product status with standard availability and identical specifications to the original part.

Q: Do the substitute parts meet the same compliance standards as the original?

A: Both substitutes maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. DF22-4P-7.92DSA(53) carries ROHS3 compliance certification. RoHS compliance status for DF22-4P-7.92DSA(23) is not specified in available data.
