DF11-24DP-2DS(22) Equivalent & Substitute Parts

Part Overview

The DF11-24DP-2DS(22) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-board or cable applications. This connector features 24 positions arranged in 2 rows with 0.079" (2.00mm) pitch spacing, tin-plated brass contacts, and shrouded 4-wall construction. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the DF11-24DP-2DS(22) is determined by strict equivalence across the following critical parameters:

• Connector series and base product number (DF11)
• Position count and row configuration (24 positions, 2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting type and orientation (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact type and material (Male Pin, Brass)
• Termination method (Solder)
• Fastening mechanism (Detent Lock)
• Electrical ratings (2A current, 250V voltage)
• Mechanical dimensions (contact lengths, insulation height)

The identified substitute parts DF11-24DP-2DS(24) and DF11-24DP-2DS(52) maintain full equivalence across all these parameters. Variations exist only in contact finish specification and product status, which do not affect mechanical or electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both DF11-24DP-2DS(24) and DF11-24DP-2DS(52) are direct functional equivalents to the obsolete DF11-24DP-2DS(22) and are suitable for replacement in new designs and production applications.

DF11-24DP-2DS(24) is the primary substitute, offering tin-plated contact finish identical to the original part. This variant is active in production, ROHS3 compliant, and maintains the same electrical and mechanical specifications. The extended operating temperature range (-40°C to 85°C versus -30°C to 85°C) provides improved thermal performance.

DF11-24DP-2DS(52) is the manufacturer-recommended alternative, featuring gold-plated contact finish for enhanced corrosion resistance and contact reliability. This variant is also active in production and ROHS3 compliant. The gold plating provides superior performance in high-reliability applications and environments with potential corrosion exposure, though it represents a higher-cost option.

Selection between these two substitutes should be based on application requirements: DF11-24DP-2DS(24) for standard applications requiring RoHS compliance and cost efficiency, or DF11-24DP-2DS(52) for applications demanding enhanced contact durability and corrosion resistance.

Frequently Asked Questions (FAQ)

Q: Are DF11-24DP-2DS(24) and DF11-24DP-2DS(52) mechanically interchangeable with DF11-24DP-2DS(22)?

A: Yes. All three parts share identical mechanical dimensions, mounting configuration, shrouding design, and contact geometry. They are fully interchangeable at the board level without requiring PCB redesign or mechanical modification.

Q: What is the difference between the tin and gold contact finishes?

A: The DF11-24DP-2DS(24) features tin plating (1.00µm thickness), while the DF11-24DP-2DS(52) features gold plating (0.203µm thickness). Gold provides superior corrosion resistance and contact reliability in harsh environments. Tin is suitable for standard applications with adequate environmental protection.

Q: Why does the operating temperature range differ between the original part and substitutes?

A: The original DF11-24DP-2DS(22) specifies -30°C to 85°C, while both active substitutes specify -40°C to 85°C. The extended lower temperature limit in the substitutes represents improved material formulation and does not affect compatibility. Applications operating within the original temperature range remain fully supported.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both DF11-24DP-2DS(24) and DF11-24DP-2DS(52) are ROHS3 compliant. The original DF11-24DP-2DS(22) is RoHS non-compliant. For applications requiring RoHS compliance, either substitute part is appropriate.

Q: What packaging is available for the substitute parts?

A: Both substitute parts are supplied in tube packaging. The original part packaging specification was not provided. Tube packaging is standard for through-hole connector components and is suitable for both manual and automated assembly processes.

Q: Can I use DF11-24DP-2DS(52) as a direct replacement for DF11-24DP-2DS(24)?

A: Yes. The gold-plated DF11-24DP-2DS(52) is electrically and mechanically equivalent to the tin-plated DF11-24DP-2DS(24). The enhanced contact finish does not introduce any compatibility issues and provides additional performance benefits in corrosion-prone environments.

Q: Which substitute should I select for new product designs?

A: For new designs, DF11-24DP-2DS(24) is the recommended primary choice, offering cost efficiency and full RoHS compliance. Select DF11-24DP-2DS(52) if the application requires enhanced corrosion resistance, high-reliability performance, or operation in harsh environmental conditions.
