DF11-18DP-2DS(22) Equivalent & Substitute Parts

Part Overview

The DF11-18DP-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 18 positions arranged in 2 rows with 0.079" (2.00mm) pitch spacing, tin-plated brass contacts, and shrouded 4-wall construction. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF11-18DP-2DS(22) is determined by strict equivalence across the following critical parameters:

• Connector series and base product number (DF11)
• Position count and row configuration (18 positions, 2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting style (through-hole, right-angle)
• Shrouding configuration (shrouded 4-wall)
• Contact type and material (male pin, brass)
• Electrical ratings (2A current, 250V voltage)
• Termination method (solder)
• Flammability and insulation specifications (UL94 V-0, polyamide/nylon)

The identified substitutes maintain full compatibility across these core parameters. Variations in contact finish (tin versus gold plating), operating temperature range, RoHS compliance status, and product lifecycle status are secondary differentiators that do not affect mechanical or electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both DF11-18DP-2DS(24) and DF11-18DP-2DS(52) are direct substitutes for the obsolete DF11-18DP-2DS(22), with full mechanical and electrical compatibility.

DF11-18DP-2DS(24) is the primary direct equivalent. It maintains tin contact finish identical to the original part, extends the operating temperature range to -40°C ~ 85°C, and achieves ROHS3 compliance. This part is recommended for applications requiring tin-plated contacts and is available in tube packaging with substantial inventory.

DF11-18DP-2DS(52) is the manufacturer-recommended alternative. It features gold-plated mating contacts, extends the operating temperature range to -40°C ~ 85°C, and achieves ROHS3 compliance. The gold finish provides enhanced corrosion resistance and contact reliability in demanding environments. This part carries the highest inventory availability and is designated as the preferred long-term solution.

Both substitutes are active products with established supply chains, eliminating obsolescence risk. Selection between them depends on contact finish requirements: tin for cost-optimized applications, gold for enhanced reliability and environmental resistance.

Frequently Asked Questions (FAQ)

Q: Can DF11-18DP-2DS(24) and DF11-18DP-2DS(52) be used interchangeably with DF11-18DP-2DS(22)?

A: Yes. Both parts are mechanically and electrically equivalent. They share identical position count, pitch spacing, mounting configuration, shrouding, current and voltage ratings, and flammability specifications. The primary differences are contact finish (tin versus gold) and RoHS compliance status, neither of which affects interchangeability.

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

A: Tin-plated contacts (DF11-18DP-2DS(24)) provide cost-effective performance for standard applications. Gold-plated contacts (DF11-18DP-2DS(52)) offer superior corrosion resistance, lower contact resistance, and enhanced reliability in high-reliability or harsh environment applications. Both finishes meet the electrical requirements of the connector series.

Q: Why does DF11-18DP-2DS(22) show an obsolete status?

A: The original part has been superseded by active production variants. The DF11-18DP-2DS(24) and DF11-18DP-2DS(52) represent the current manufacturing standard for this connector configuration and are recommended for all new designs.

Q: Are there any temperature rating differences I should consider?

A: The original DF11-18DP-2DS(22) operates from -30°C to 85°C. Both substitutes extend the lower temperature limit to -40°C, providing broader operational range. This enhancement does not affect compatibility; applications within the original -30°C to 85°C range remain fully supported.

Q: What does ROHS3 compliance mean for this connector?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The original DF11-18DP-2DS(22) is RoHS non-compliant. Both substitutes achieve ROHS3 compliance, making them suitable for applications with regulatory requirements.

Q: How should I choose between DF11-18DP-2DS(24) and DF11-18DP-2DS(52)?

A: Use DF11-18DP-2DS(24) for standard applications where tin contact finish is acceptable and cost optimization is a priority. Use DF11-18DP-2DS(52) for high-reliability applications, harsh environments, or when gold contact finish is specified. Both are fully compatible with the original design.

Q: Is packaging a consideration for substitution?

A: Packaging (tube) affects handling and storage but does not impact electrical or mechanical performance. Both substitutes are supplied in tube packaging, suitable for automated assembly processes.
