DF22-3P-7.92DS(05) Equivalent & Substitute Parts

Part Overview

The DF22-3P-7.92DS(05) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This 3-position connector operates at 1000V with a 25A current rating and features a 0.312" (7.92mm) pitch. The part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF22-3P-7.92DS(05) is determined by the following critical parameters:

• Connector geometry: 3-position, 0.312" (7.92mm) pitch, through-hole right-angle header with shrouded 4-wall design
• Electrical ratings: 1000V voltage rating and compatible current handling
• Mounting interface: Through-hole, right-angle orientation for board-to-cable/wire connections
• Material compliance: UL94 V-0 flammability rating and RoHS compliance status
• Contact configuration: Male pin contacts with solder termination and latch holder fastening

Two active substitute parts meet these criteria: DF22-3P-7.92DS(23) and DF22-3P-7.92DS(53). Both maintain identical mechanical dimensions, electrical ratings, and core functional specifications while offering improved product status and enhanced contact finishes.

Parameter Comparison

Engineering Selection Recommendations

DF22-3P-7.92DS(53) is the primary recommended substitute. This part maintains active product status, offers ROHS3 compliance certification, and provides gold-plated contacts with documented finish thickness (8.00µin / 0.203µm) on both mating and post surfaces. The extended operating temperature range (-55°C ~ 85°C) provides additional thermal margin compared to the obsolete original part. Highest inventory availability (1157 pcs) supports procurement reliability.

DF22-3P-7.92DS(23) serves as a secondary alternative, maintaining active status and extended temperature range (-55°C ~ 85°C). This variant features gold-plated mating contacts and glass-filled nylon insulation material, offering enhanced mechanical properties. Current rating specification differs from the original (varies by wire gauge versus fixed 25A), requiring verification against application requirements.

Both substitutes eliminate obsolescence risk while maintaining mechanical and electrical compatibility with the original DF22-3P-7.92DS(05) specification.

Frequently Asked Questions (FAQ)

Q: Can DF22-3P-7.92DS(23) and DF22-3P-7.92DS(53) be used interchangeably with DF22-3P-7.92DS(05)?

A: Both parts maintain identical connector geometry, pitch (0.312" / 7.92mm), mounting configuration (through-hole right-angle), and electrical ratings (1000V). Mechanical and electrical interchangeability is confirmed. Contact finish differences (tin-copper versus gold) and insulation material variations do not affect functional compatibility in standard applications.

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

A: Gold plating provides enhanced corrosion resistance and improved contact reliability over extended service life. The tin-copper finish on the original part is functionally equivalent for most applications; gold plating represents a material upgrade available in the substitute parts.

Q: Why does DF22-3P-7.92DS(23) specify "varies by wire gauge" for current rating instead of a fixed 25A value?

A: Current rating in DF22-3P-7.92DS(23) is dependent on the wire gauge of the mated cable/wire assembly. Applications requiring the fixed 25A specification should reference DF22-3P-7.92DS(53), which maintains the original current rating specification.

Q: Are there compliance differences between the substitute parts?

A: DF22-3P-7.92DS(53) carries ROHS3 certification, representing the most current compliance standard. DF22-3P-7.92DS(23) compliance status is not specified in available documentation. Both parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1).

Q: What is the packaging difference between DF22-3P-7.92DS(53) and the original part?

A: DF22-3P-7.92DS(53) is supplied in bag packaging, while the original part packaging is not specified. This difference does not affect connector functionality or performance.

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

A: DF22-3P-7.92DS(53) is recommended for new designs due to active product status, current ROHS3 compliance certification, and documented contact finish specifications. This part provides the longest product lifecycle support and highest procurement availability.
