DF22-2P-7.92DSA(35) Equivalent & Substitute Parts

Part Overview

The DF22-2P-7.92DSA(35) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole board-to-cable/wire applications with 2 positions at 7.92mm pitch. This connector features shrouded 4-wall construction with solder termination and latch holder fastening. The part is currently obsolete, making identification of active equivalent models essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF22-2P-7.92DSA(35) is determined by the following critical parameters that must remain constant:

• Manufacturer: Hirose Electric Co Ltd (DF22 series family)
• Number of Positions: 2
• Pitch - Mating: 0.312" (7.92mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Latch Holder
• Voltage Rating: 1000V
• Material Flammability Rating: UL94 V-0

The substitute parts identified maintain these core electrical and mechanical parameters. Variations in contact finish, insulation material composition, and operating temperature range are permissible within the DF22 series architecture.

Parameter Comparison

Engineering Selection Recommendations

Both DF22-2P-7.92DSA(23) and DF22-2P-7.92DSA(53) are active product alternatives to the obsolete DF22-2P-7.92DSA(35).

DF22-2P-7.92DSA(53) is the primary recommended substitute. It maintains identical mechanical and electrical specifications to the original part, including square contact shape, tin contact finish on mating surfaces, and beige insulation color. This variant includes board lock features and achieves ROHS3 compliance with REACH unaffected status. Operating temperature range extends to -55°C, providing enhanced low-temperature performance.

DF22-2P-7.92DSA(23) serves as an alternative substitute with extended operating temperature range (-55°C ~ 85°C) and gold contact finish on mating surfaces. This variant incorporates glass-filled nylon insulation and features rectangular contact geometry. Current rating is specified as varying by wire gauge rather than a fixed 25A rating.

Both substitutes maintain the critical parameters: 2-position configuration, 7.92mm pitch, through-hole mounting, shrouded 4-wall construction, solder termination, latch holder fastening, 1000V voltage rating, and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can DF22-2P-7.92DSA(23) and DF22-2P-7.92DSA(53) be used interchangeably with DF22-2P-7.92DSA(35)?

A: Both parts maintain the core mechanical and electrical parameters required for functional substitution within the DF22 series. Contact finish differences (tin versus gold) and contact shape variations (square versus rectangular) do not affect mating compatibility or electrical performance at the specified voltage and current ratings.

Q: What is the significance of the contact finish difference between tin and gold?

A: Contact finish affects corrosion resistance and contact resistance characteristics. Gold-plated contacts (DF22-2P-7.92DSA(23) and DF22-2P-7.92DSA(53)) provide superior corrosion resistance compared to tin-plated contacts (DF22-2P-7.92DSA(35)). Both finishes are suitable for the specified 1000V and current applications.

Q: Does the extended operating temperature range of the substitute parts affect compatibility?

A: The substitute parts support extended low-temperature operation (-55°C versus -35°C). This represents an enhancement rather than a limitation. Applications requiring only the original -35°C ~ 85°C range remain fully compatible.

Q: What is the difference between square and rectangular contact shapes?

A: Contact shape variation between DF22-2P-7.92DSA(35) (square) and DF22-2P-7.92DSA(23) (rectangular) does not affect electrical performance or mating compatibility within the DF22 series architecture. Both geometries maintain the specified pitch, voltage, and current ratings.

Q: Are there compliance differences between the substitute parts?

A: DF22-2P-7.92DSA(53) achieves ROHS3 compliance with REACH unaffected status. DF22-2P-7.92DSA(23) compliance status is not specified in available documentation. Both parts maintain UL94 V-0 flammability rating and EAR99 export classification.

Q: How does insulation material composition affect part selection?

A: DF22-2P-7.92DSA(35) and DF22-2P-7.92DSA(53) use standard polyamide nylon insulation. DF22-2P-7.92DSA(23) incorporates glass-filled nylon, which provides enhanced mechanical strength and thermal stability. Material selection does not affect electrical performance at the specified voltage and current ratings.
