DF11-10DP-2DSA(20) Equivalent & Substitute Parts

Part Overview

The DF11-10DP-2DSA(20) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting in board-to-board or cable applications. This connector features a vertical orientation with 10 positions arranged in 2 rows at 2.00mm pitch, shrouded with 4-wall protection, and rated for 2A at 250V operation across -30°C to 85°C. The part is currently classified as obsolete, necessitating identification of equivalent alternatives to maintain design continuity and ensure component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitution eligibility for the DF11-10DP-2DSA(20) is determined by strict alignment of the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Pitch configuration (0.079" / 2.00mm mating pitch)
Position count (10 positions in 2 rows)
Row spacing (0.079" / 2.00mm)
Mounting method (Through Hole)
Shrouding configuration (Shrouded - 4 Wall)
Termination method (Solder)
Fastening type (Detent Lock)
Material flammability compliance (UL94 V-0)

Substitute parts must maintain these parameters to ensure mechanical and electrical compatibility with existing PCB designs and mating connectors. Variations in current rating, voltage rating, or operating temperature range do not preclude substitution provided the substitute meets or exceeds the original specification.

Engineering Selection Recommendations

DF11-10DP-2DSA(24) is the direct equivalent substitute from Hirose Electric Co Ltd. This part maintains identical electrical and mechanical specifications to the obsolete DF11-10DP-2DSA(20) while offering active product status and ROHS3 compliance. The packaging difference (Tube versus original specification) does not affect functional compatibility. This substitute is the preferred selection for direct replacement in existing designs.

SWR204-NRTN-D05-ST-GA from Sullins Connector Solutions provides an alternative rectangular connector header with identical pitch, position count, row configuration, and shrouding. This part is active and ROHS3 compliant. However, the voltage rating of 50V is significantly lower than the original 250V specification, and the operating temperature minimum is -25°C compared to -30°C. Selection of this substitute requires verification that the application voltage and temperature requirements do not exceed these limits. The higher current rating of 3A per contact exceeds the original 2A specification.

Frequently Asked Questions (FAQ)

Q: Can DF11-10DP-2DSA(24) be used as a direct replacement for DF11-10DP-2DSA(20)?

A: Yes. Both parts share identical connector type, pitch, position count, row spacing, mounting method, shrouding, and electrical ratings. The packaging format difference does not affect functional compatibility.

Q: What are the key differences between DF11-10DP-2DSA(24) and SWR204-NRTN-D05-ST-GA?

A: Both maintain the same pitch, position count, and shrouding configuration. The primary differences are manufacturer (Hirose versus Sullins), voltage rating (250V versus 50V), minimum operating temperature (-30°C versus -25°C), and insulation material composition (PA versus PA66). The SWR204 offers higher current capacity at 3A per contact.

Q: Is the SWR204-NRTN-D05-ST-GA suitable for applications requiring 250V operation?

A: No. The SWR204-NRTN-D05-ST-GA is rated for 50V maximum. Applications requiring 250V operation must use DF11-10DP-2DSA(24) or equivalent Hirose parts.

Q: Does packaging format affect connector performance?

A: No. Packaging format (Tube, Bulk, or other) affects handling, storage, and ordering logistics but does not alter electrical or mechanical performance of the connector itself.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both DF11-10DP-2DSA(24) and SWR204-NRTN-D05-ST-GA are ROHS3 compliant, whereas the original DF11-10DP-2DSA(20) is RoHS non-compliant.

Q: What is the minimum operating temperature difference between substitutes?

A: DF11-10DP-2DSA(24) operates from -30°C, while SWR204-NRTN-D05-ST-GA operates from -25°C. Applications requiring operation below -25°C must use the Hirose DF11-10DP-2DSA(24).
