Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF22-1P-7.92DSA(05) is determined by the following critical parameters:

• Connector Type & Series: Must be DF22 series header connector
• Number of Positions & Rows: Must maintain 1 position, 1 row configuration
• Mounting & Termination: Through-hole solder termination required
• Electrical Ratings: Minimum 30A current capacity and 1000V voltage rating
• Operating Temperature Range: Must support -35°C to 85°C minimum
• Shrouding & Fastening: Shrouded 4-wall design with latch holder fastening
• Material Compliance: UL94 V-0 flammability rating and RoHS compliance required

The identified substitute parts maintain these core parameters while differing in contact finish specifications and product status classifications.

Parameter Comparison

Engineering Selection Recommendations

DF22-1P-7.92DSA(27) is the primary recommended substitute. This part maintains active product status with Hirose Electric Co Ltd, ensuring ongoing availability and technical support. It meets all critical electrical and mechanical parameters: 1-position header configuration, through-hole solder termination, shrouded 4-wall design, and latch holder fastening. The operating temperature range extends to -55°C, providing enhanced low-temperature performance beyond the original specification. Contact finish differs (gold versus tin-copper), and insulation material includes glass-filled nylon for improved mechanical properties. Current rating specification varies by wire gauge rather than fixed amperage; verify compatibility with your application's wire gauge requirements.

DF22-1P-7.92DSA(57) serves as a secondary alternative, maintaining RoHS compliance and identical connector configuration. However, this part carries obsolete product status classification, limiting long-term procurement viability. Use this substitute only when DF22-1P-7.92DSA(27) availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can DF22-1P-7.92DSA(27) directly replace DF22-1P-7.92DSA(05) in existing designs?

A: Yes, for applications requiring the specified electrical ratings and operating temperature range. The primary difference is contact finish (gold versus tin-copper) and extended low-temperature capability (-55°C versus -35°C). Verify wire gauge compatibility, as current rating for DF22-1P-7.92DSA(27) varies by wire gauge rather than fixed 30A specification.

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

A: DF22-1P-7.92DSA(05) features tin-copper mating contact finish, while DF22-1P-7.92DSA(27) uses gold finish. Gold provides superior corrosion resistance and lower contact resistance, particularly beneficial in high-reliability applications. Both finishes meet the 1000V rating and support equivalent current-carrying capacity within their respective specifications.

Q: Why is DF22-1P-7.92DSA(27) recommended over DF22-1P-7.92DSA(57)?

A: DF22-1P-7.92DSA(27) maintains active product status, ensuring manufacturer support, consistent availability, and documented technical specifications. DF22-1P-7.92DSA(57) is classified as obsolete, presenting long-term procurement risk. Select DF22-1P-7.92DSA(27) for new designs and ongoing production requirements.

Q: Are there packaging differences between these substitute parts?

A: DF22-1P-7.92DSA(05) and DF22-1P-7.92DSA(27) packaging specifications are not detailed in available documentation. DF22-1P-7.92DSA(57) is supplied in tray packaging. Confirm packaging requirements with your procurement specification before finalizing component selection.

Q: Do all three parts meet RoHS compliance requirements?

A: DF22-1P-7.92DSA(05) and DF22-1P-7.92DSA(57) are explicitly RoHS compliant. RoHS status for DF22-1P-7.92DSA(27) is not specified in available data. Verify RoHS compliance documentation directly with Hirose Electric Co Ltd if this certification is mandatory for your application.
