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

Part Overview

The DF11-22DP-2DSA(20) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting applications requiring board-to-board or cable connections. This 22-position, 2-row connector operates at 2A per contact and 250V, with a 2.00mm pitch and shrouded 4-wall design. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the DF11-22DP-2DSA(20) is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (22), number of rows (2), pitch (2.00mm), row spacing (2.00mm), mounting type (through hole), shrouding configuration (shrouded 4-wall), and electrical ratings (minimum 2A current, minimum 250V voltage). Parts meeting these specifications are considered functionally equivalent for PCB layout and mating interface purposes.

The DF11-22DP-2DSA(24) from Hirose Electric maintains identical mechanical and electrical specifications to the original part, with the primary distinction being active product status and RoHS3 compliance. The SWR204-NRTN-D11-ST-GA from Sullins Connector Solutions meets the core substitution criteria of pitch, position count, row configuration, and shrouding, though with variations in insulation material (PA66 vs PA), insulation height (6.50mm vs 6.60mm), and current rating (3A vs 2A per contact).

Engineering Selection Recommendations

The DF11-22DP-2DSA(24) is the primary substitute for the obsolete DF11-22DP-2DSA(20). Both parts are manufactured by Hirose Electric and maintain identical mechanical and electrical specifications. The DF11-22DP-2DSA(24) offers the advantage of active product status and ROHS3 compliance, making it suitable for new designs and applications requiring regulatory adherence. Inventory availability is higher for the DF11-22DP-2DSA(24) at 1333 pieces compared to 750 pieces for the original part.

The SWR204-NRTN-D11-ST-GA from Sullins Connector Solutions is an alternative substitute that meets the core mechanical interface requirements. However, this part exhibits the following deviations: reduced voltage rating (50V versus 250V), increased current rating per contact (3A versus 2A), different insulation material composition (PA66 versus PA), and slightly reduced insulation height (6.50mm versus 6.60mm). Selection of the SWR204-NRTN-D11-ST-GA requires verification that the application's voltage requirements do not exceed 50V and that the mechanical tolerance of the reduced insulation height is acceptable for the PCB layout.

Frequently Asked Questions (FAQ)

Q: Can the DF11-22DP-2DSA(24) be used as a direct replacement for the DF11-22DP-2DSA(20)?

A: Yes. Both parts share identical connector type, position count, row configuration, pitch, shrouding, mounting type, and electrical ratings. The DF11-22DP-2DSA(24) is the direct successor with active product status and improved compliance.

Q: What are the key differences between the DF11-22DP-2DSA(24) and the SWR204-NRTN-D11-ST-GA?

A: The primary differences are voltage rating (250V versus 50V), current rating per contact (2A versus 3A), insulation material (PA versus PA66), and insulation height (6.60mm versus 6.50mm). Both maintain the same pitch, position count, and shrouding configuration.

Q: Is the SWR204-NRTN-D11-ST-GA suitable for applications requiring 250V operation?

A: No. The SWR204-NRTN-D11-ST-GA has a maximum voltage rating of 50V and is not suitable for applications exceeding this specification.

Q: What is the impact of the reduced insulation height in the SWR204-NRTN-D11-ST-GA?

A: The insulation height difference of 0.10mm (6.50mm versus 6.60mm) may affect PCB layout clearances and mating interface tolerances. Verification against specific PCB design requirements is necessary.

Q: Are all three parts RoHS compliant?

A: The DF11-22DP-2DSA(20) is RoHS non-compliant. Both the DF11-22DP-2DSA(24) and SWR204-NRTN-D11-ST-GA are ROHS3 compliant.

Q: What is the packaging difference between the substitute parts?

A: The DF11-22DP-2DSA(24) is supplied in tube packaging, while the SWR204-NRTN-D11-ST-GA is supplied in bulk packaging. The original DF11-22DP-2DSA(20) packaging specification is not provided.
