Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF22-1P-7.92DSA(25) is determined by the following critical parameters:

• Connector Type & Configuration: Header, single position, shrouded 4-wall design, board-to-cable/wire style
• Electrical Ratings: Minimum 30A current capacity and 1000V voltage rating
• Mechanical Compatibility: Through-hole mounting, solder termination, latch holder fastening
• Contact Specifications: Male pin contact type with copper alloy material
• Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1 rating
• Pitch & Dimensions: 7.92mm pitch with compatible insulation height and contact lengths

The following parts meet these substitution criteria:

DF22-1P-7.92DSA(27) — Active status alternative with equivalent mechanical and electrical specifications, featuring gold contact finish and extended operating temperature range (-55°C ~ 85°C).

DF22-1P-7.92DSA(57) — Obsolete equivalent with identical core specifications, available in tray packaging.

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 continued availability and technical support. It provides equivalent mechanical and electrical performance with enhanced operating temperature range (-55°C ~ 85°C versus -35°C ~ 85°C), glass-filled nylon insulation for improved mechanical properties, and gold contact finish for superior corrosion resistance. Current inventory of 905 units supports immediate procurement.

DF22-1P-7.92DSA(57) serves as a secondary equivalent for applications where inventory from existing stock is prioritized. Both parts share identical core specifications with the original DF22-1P-7.92DSA(25), including shrouded 4-wall design, through-hole mounting, and UL94 V-0 compliance. However, DF22-1P-7.92DSA(57) carries obsolete status, limiting long-term availability.

For new designs or long-term production requirements, DF22-1P-7.92DSA(27) is the appropriate selection due to active product status and enhanced material specifications.

Frequently Asked Questions (FAQ)

Q: Can DF22-1P-7.92DSA(27) directly replace DF22-1P-7.92DSA(25) in existing assemblies?

A: Yes. Both parts share identical connector type, single-position configuration, shrouded 4-wall design, through-hole mounting, and solder termination. Mechanical and electrical compatibility is maintained. The gold contact finish on DF22-1P-7.92DSA(27) provides enhanced performance characteristics.

Q: What is the difference between the contact finishes on these parts?

A: DF22-1P-7.92DSA(25) features tin contact finish on the mating surface. DF22-1P-7.92DSA(27) uses gold contact finish, which provides superior corrosion resistance and improved contact reliability in demanding environments.

Q: Are there temperature rating differences between substitutes?

A: DF22-1P-7.92DSA(27) operates across -55°C ~ 85°C, compared to -35°C ~ 85°C for DF22-1P-7.92DSA(25). This extended lower temperature range provides additional operational margin for cold-environment applications.

Q: What is the significance of glass-filled nylon insulation in DF22-1P-7.92DSA(27)?

A: Glass-filled polyamide nylon in DF22-1P-7.92DSA(27) provides enhanced mechanical strength, dimensional stability, and thermal performance compared to standard nylon insulation in DF22-1P-7.92DSA(25).

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

A: DF22-1P-7.92DSA(27) maintains active product status with the manufacturer, ensuring continued availability, technical documentation, and supply chain support. DF22-1P-7.92DSA(57) is obsolete, limiting future procurement options.

Q: Are all three parts RoHS compliant?

A: DF22-1P-7.92DSA(25) and DF22-1P-7.92DSA(57) are confirmed RoHS compliant. RoHS status for DF22-1P-7.92DSA(27) is not specified in available documentation but is standard for current Hirose DF22 series production.
