DF11-20DS-2DSA Equivalent & Substitute Parts

Part Overview

The DF11-20DS-2DSA is a 20-position receptacle connector manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch mating. This connector features through-hole mounting with press-fit and solder termination options, tin-plated contacts, and operates across -30°C to 85°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF11-20DS-2DSA is determined by the following critical parameters: connector type (receptacle vs. header), contact type (female socket vs. male pin), number of positions (20), pitch spacing (0.079" / 2.00mm), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (through hole), and electrical ratings (2A minimum current, 250V minimum voltage).

The direct manufacturer substitute DF11-20DS-2DSA(05) maintains identical mechanical and electrical specifications while offering active product status and improved compliance. Cross-manufacturer substitutes from TE Connectivity (2-1470109-0) and Sullins Connector Solutions (SWR204-NRTN-D10-ST-GA) are header connectors with male pins rather than receptacle female sockets, requiring mating with the original receptacle design. These alternatives share the same pitch, row configuration, through-hole mounting, and UL94 V-0 flammability rating but differ in connector type and contact gender.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the obsolete DF11-20DS-2DSA, the DF11-20DS-2DSA(05) is the primary equivalent. This part maintains identical mechanical and electrical specifications while offering active product status, improved availability (4483 pcs in stock vs. 1600 pcs), and ROHS3 compliance. The contact material differs (brass vs. phosphor bronze) and contact finish thickness is specified (2.00µm), but these variations remain within acceptable substitution parameters for the receptacle connector category.

The TE Connectivity 2-1470109-0 and Sullins SWR204-NRTN-D10-ST-GA are header connectors with male pins, not receptacles with female sockets. These parts are suitable only when the mating receptacle connector is available or when the application design permits header-to-header mating. Both alternatives provide higher current ratings (3A) and UL94 V-0 compliance but operate at reduced voltage ratings (100VDC and 50V respectively) compared to the original 250V specification. The TE Connectivity part offers RoHS compliance, while the Sullins part provides ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can DF11-20DS-2DSA(05) be used as a direct drop-in replacement?

A: Yes. The DF11-20DS-2DSA(05) maintains identical pitch (0.079" / 2.00mm), row configuration (2 rows, 0.079" spacing), number of positions (20), mounting type (through hole), and electrical ratings (2A, 250V). The part is mechanically and electrically compatible with the original design.

Q: Why do the TE Connectivity and Sullins parts have different connector types?

A: The 2-1470109-0 and SWR204-NRTN-D10-ST-GA are header connectors with male pins, while the DF11-20DS-2DSA is a receptacle with female sockets. These parts are complementary connector types designed to mate with each other. They cannot replace the receptacle directly but can be used as mating partners in board-to-board applications.

Q: What are the voltage rating differences between substitutes?

A: The original DF11-20DS-2DSA and its direct equivalent DF11-20DS-2DSA(05) are rated for 250V. The TE Connectivity 2-1470109-0 is rated for 100VDC, and the Sullins SWR204-NRTN-D10-ST-GA is rated for 50V. Applications requiring the full 250V rating must use the Hirose receptacle connectors.

Q: What is the difference in packaging between these parts?

A: The original DF11-20DS-2DSA has unspecified packaging. The DF11-20DS-2DSA(05) is supplied in trays. The TE Connectivity 2-1470109-0 and Sullins SWR204-NRTN-D10-ST-GA are supplied in bulk packaging. Packaging selection depends on production volume and handling requirements.

Q: Are all substitute parts RoHS compliant?

A: The original DF11-20DS-2DSA is RoHS non-compliant. The DF11-20DS-2DSA(05) is ROHS3 compliant. The TE Connectivity 2-1470109-0 is RoHS compliant. The Sullins SWR204-NRTN-D10-ST-GA is ROHS3 compliant. Applications requiring RoHS compliance must use the DF11-20DS-2DSA(05), 2-1470109-0, or SWR204-NRTN-D10-ST-GA.

Q: What is the operating temperature range for each part?

A: The DF11-20DS-2DSA and DF11-20DS-2DSA(05) operate from -30°C to 85°C. The TE Connectivity 2-1470109-0 and Sullins SWR204-NRTN-D10-ST-GA operate from -25°C to 85°C. Applications requiring operation below -25°C must use the Hirose receptacle connectors.
