DF11-20DP-2DS(22) Equivalent & Substitute Parts

Part Overview

The DF11-20DP-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 20 positions arranged in 2 rows with 0.079" (2.00mm) pitch spacing, shrouded 4-wall construction, and solder termination with detent lock fastening. 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 eligibility for the DF11-20DP-2DS(22) is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Number of positions and row configuration (20 positions, 2 rows)
• Mating pitch and row spacing (0.079" / 2.00mm)
• Mounting style and orientation (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Detent Lock)
• Electrical ratings (2A current, 250V voltage)
• Material specifications (Brass contacts, Polyamide insulation)
• Flammability compliance (UL94 V-0)

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

Parameter Comparison

Engineering Selection Recommendations

Both DF11-20DP-2DS(24) and DF11-20DP-2DS(52) are direct functional equivalents to the obsolete DF11-20DP-2DS(22) for connector interface applications. Selection between these active alternatives should be based on the following criteria:

DF11-20DP-2DS(24) is the primary direct substitute, maintaining tin contact finish identical to the original part. This variant is ROHS3 compliant and offers an extended operating temperature range of -40°C to 85°C. With 2906 units in stock, this part provides the closest electrical and material match to the original specification.

DF11-20DP-2DS(52) is the manufacturer-recommended alternative, featuring gold contact finish instead of tin. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments. This variant is also ROHS3 compliant with the same extended temperature range. With 1137 units available, this option is suitable for applications requiring superior contact durability or where gold-plated contacts are specified.

Both substitutes are active products with established supply chains, eliminating obsolescence risk associated with the original part. Selection between them depends on contact finish requirements and application-specific environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can DF11-20DP-2DS(24) and DF11-20DP-2DS(52) be used interchangeably with DF11-20DP-2DS(22)?

A: Yes. Both substitutes maintain identical mechanical and electrical interface specifications. The connector pitch, position count, row spacing, mounting configuration, shrouding, termination method, and fastening mechanism are fully compatible. The primary differences are contact finish material and product lifecycle status.

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

A: Tin contact finish, used in DF11-20DP-2DS(24), provides standard electrical conductivity and is suitable for general applications. Gold contact finish, used in DF11-20DP-2DS(52), offers superior corrosion resistance and is preferred in high-reliability or harsh environment applications. Both finishes meet the 2A current and 250V voltage ratings.

Q: Why does DF11-20DP-2DS(22) show as obsolete?

A: The original part has been discontinued by the manufacturer. Hirose Electric Co Ltd has transitioned production to the active variants DF11-20DP-2DS(24) and DF11-20DP-2DS(52), which incorporate improvements such as ROHS3 compliance and extended temperature range.

Q: Are there packaging differences between the substitutes?

A: The original part shows no specified packaging designation. Both active substitutes are supplied in tube packaging, which is standard for connector headers and does not affect connector performance or compatibility.

Q: What is the significance of ROHS3 compliance?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting specific hazardous materials. Both active substitutes are ROHS3 compliant, while the original part is non-compliant. For new designs or regulatory requirements, the compliant variants are preferred.

Q: Can I use DF11-20DP-2DS(52) in applications originally designed for DF11-20DP-2DS(22)?

A: Yes. The gold-plated variant is mechanically and electrically interchangeable. The enhanced contact finish provides equal or superior performance in the same application space, with no design modifications required.

Q: What is the operating temperature difference, and does it matter?

A: The original part operates from -30°C to 85°C, while both substitutes operate from -40°C to 85°C. The extended lower temperature range in the substitutes provides additional margin for cold environment applications. For standard operating conditions, this difference is not a limiting factor.
