DF11-24DS-2DSA Equivalent & Substitute Parts

Part Overview

The DF11-24DS-2DSA is a 24-position receptacle connector manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch spacing. 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 DF11-24DS-2DSA is determined by the following critical parameters: connector type (receptacle vs. header), contact type (female socket vs. male pin), number of positions (24), pitch spacing (0.079" / 2.00mm), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (through hole), and electrical ratings (current and voltage capacity).

The substitute parts are grouped into two categories:

Direct Equivalent (Same Connector Type): DF11-24DS-2DSA(05) maintains identical receptacle configuration, contact type, and electrical specifications as the original part, with the primary difference being active product status and RoHS3 compliance.

Mating Header Alternatives (Complementary Connector Type): 2-1470109-4 (TE Connectivity) and SWR204-NRTN-D12-ST-GA (Sullins Connector Solutions) are header connectors designed to mate with receptacle connectors of matching pitch and position count. These parts share the same 24-position, 2.00mm pitch, 2-row configuration and through-hole mounting, but feature male pins instead of female sockets. Selection of header alternatives requires confirmation that the mating receptacle connector is compatible with the intended application.

Parameter Comparison

Engineering Selection Recommendations

DF11-24DS-2DSA(05) is the primary direct substitute for the obsolete DF11-24DS-2DSA. Both parts are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications. The DF11-24DS-2DSA(05) is currently in active production status with 3023 units in stock, compared to 755 units of the obsolete original part. This substitute achieves ROHS3 compliance and includes specified contact finish thickness specifications (78.7µin / 2.00µm on both mating and post surfaces), addressing regulatory requirements for new designs and production runs.

2-1470109-4 (TE Connectivity AMP Connectors) and SWR204-NRTN-D12-ST-GA (Sullins Connector Solutions) are header connector alternatives suitable only when the application requires a mating header connector rather than a receptacle. Both parts are active products with ROHS3 compliance. The TE Connectivity part supports higher current capacity (3A vs. 2A) and higher voltage rating (100VDC vs. 250V on the original), while the Sullins part supports 3A per contact with a 50V voltage rating. Selection between these header alternatives depends on specific voltage and current requirements of the application, as the original DF11-24DS-2DSA receptacle operates at 250V, which exceeds the voltage ratings of both header substitutes.

Frequently Asked Questions (FAQ)

Q: Can DF11-24DS-2DSA(05) be used as a direct replacement for DF11-24DS-2DSA?

A: Yes. Both parts are 24-position receptacle connectors with identical pitch (0.079" / 2.00mm), row spacing, mounting type, and electrical ratings. The DF11-24DS-2DSA(05) is the active production equivalent and is recommended for all new applications and production replacements.

Q: What is the difference between the receptacle DF11-24DS-2DSA and the header alternatives 2-1470109-4 and SWR204-NRTN-D12-ST-GA?

A: The DF11-24DS-2DSA is a receptacle connector with female sockets designed to accept male pins from a mating header. The 2-1470109-4 and SWR204-NRTN-D12-ST-GA are header connectors with male pins. These parts are complementary and mate together. Selection depends on whether your application requires a receptacle (female socket) or header (male pin) connector.

Q: Are the voltage ratings of the header alternatives sufficient for applications using the original DF11-24DS-2DSA?

A: The original DF11-24DS-2DSA is rated for 250V. The TE Connectivity 2-1470109-4 is rated for 100VDC, and the Sullins SWR204-NRTN-D12-ST-GA is rated for 50V. If your application requires 250V operation, the header alternatives do not meet the voltage specification. Verify application voltage requirements before selecting a substitute.

Q: What is the packaging difference between DF11-24DS-2DSA and DF11-24DS-2DSA(05)?

A: The original DF11-24DS-2DSA is supplied without specified packaging. The DF11-24DS-2DSA(05) is supplied in Tray packaging. Confirm packaging requirements for your assembly process before ordering.

Q: Are all substitute parts RoHS compliant?

A: Yes. DF11-24DS-2DSA(05), 2-1470109-4, and SWR204-NRTN-D12-ST-GA are all ROHS3 compliant. The original DF11-24DS-2DSA is RoHS non-compliant.

Q: What is the current rating difference between the original part and the header alternatives?

A: The original DF11-24DS-2DSA is rated for 2A. Both header alternatives (2-1470109-4 and SWR204-NRTN-D12-ST-GA) are rated for 3A, providing higher current capacity. Verify that your application current requirements do not exceed 2A if using the original part or its direct equivalent DF11-24DS-2DSA(05).
