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

Part Overview

The DF22-2P-7.92DS(35) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-cable/wire applications. This connector features a 2-position configuration with 0.312" (7.92mm) pitch spacing and is part of the EnerBee™ DF22 series. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF22-2P-7.92DS(35) is determined by the following critical parameters:

• Connector type (Header)
• Number of positions (2)
• Pitch spacing (0.312" / 7.92mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding style (Shrouded - 4 Wall)
• Voltage rating (1000V minimum)
• Material flammability rating (UL94 V-0)
• Termination method (Solder)

Two substitute parts meet these criteria: DF22-2P-7.92DS(23) and DF22-2P-7.92DS(53). Both maintain identical mechanical and electrical specifications while differing in contact finish materials, insulation composition, and product status.

Parameter Comparison

Engineering Selection Recommendations

Both DF22-2P-7.92DS(23) and DF22-2P-7.92DS(53) are active products suitable for replacing the obsolete DF22-2P-7.92DS(35).

DF22-2P-7.92DS(53) is the preferred substitute. It maintains the original square contact shape and tin-equivalent gold contact finish with specified thickness (8.00µin / 0.203µm). This part carries ROHS3 Compliant certification and REACH Unaffected status, providing enhanced regulatory compliance for current applications. The extended operating temperature range (-55°C ~ 85°C) offers broader environmental compatibility.

DF22-2P-7.92DS(23) serves as an alternative substitute. It features gold contact finish without specified thickness and glass-filled nylon insulation material. The rectangular contact shape and extended temperature range (-55°C ~ 85°C) differ from the original specification. This part maintains RoHS Compliant status.

Both substitutes maintain identical mechanical fit, electrical ratings (1000V, 25A current capability), and UL94 V-0 flammability certification, ensuring direct functional compatibility in existing designs.

Frequently Asked Questions (FAQ)

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

A: Both parts are mechanically and electrically compatible. They share identical connector type, position count, pitch spacing, mounting configuration, shrouding style, voltage rating, and flammability rating. Differences in contact finish material and insulation composition do not affect basic substitution eligibility.

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

A: The original DF22-2P-7.92DS(35) uses tin contact finish. Both substitutes use gold finish. Gold provides enhanced corrosion resistance and contact reliability. This represents an improvement over the original specification.

Q: Why does DF22-2P-7.92DS(53) have specified contact finish thickness while DF22-2P-7.92DS(23) does not?

A: DF22-2P-7.92DS(53) includes contact finish thickness specification (8.00µin / 0.203µm) for both mating and post contacts. DF22-2P-7.92DS(23) does not provide this specification. For applications requiring precise contact resistance or wear characteristics, DF22-2P-7.92DS(53) offers defined performance parameters.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents compliance with the most current RoHS directive revision. DF22-2P-7.92DS(53) carries this designation, indicating alignment with the latest regulatory requirements. Both certifications satisfy RoHS compliance requirements.

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

A: The substitutes support -55°C ~ 85°C operation, compared to the original -35°C ~ 85°C range. This represents an expansion of the operating envelope and does not create compatibility issues. Applications operating within the original temperature range remain fully compatible.

Q: What is the difference between the contact shapes (square vs. rectangular)?

A: DF22-2P-7.92DS(35) and DF22-2P-7.92DS(53) feature square contact shapes. DF22-2P-7.92DS(23) features rectangular contacts. Contact shape affects mating force and contact pressure distribution. For direct mechanical equivalence, DF22-2P-7.92DS(53) is preferred.
