DF11-26DP-2DSA(20) Equivalent & Substitute Parts

Part Overview

The DF11-26DP-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 26-position, 2-row connector operates at 2A per contact and 250V, with a 2.00mm pitch and shrouded 4-wall design. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the DF11-26DP-2DSA(20) is determined by the following critical parameters:

Connector configuration: 26 positions, 2 rows, 2.00mm pitch
Mounting and termination: Through-hole solder termination
Electrical performance: Current and voltage ratings
Physical compatibility: Shrouding type, row spacing, and overall dimensions
Environmental compliance: Operating temperature range and flammability rating

Two substitute parts meet these criteria:

DF11-26DP-2DSA(24) — Direct Hirose equivalent with identical electrical and mechanical specifications, differing only in packaging and RoHS compliance status
SWR204-NRTN-D13-ST-GA — Sullins Connector Solutions alternative with compatible core parameters but variations in insulation height, current rating per contact, and voltage rating

Engineering Selection Recommendations

DF11-26DP-2DSA(24) is the primary substitute for the obsolete DF11-26DP-2DSA(20). Both parts are manufactured by Hirose Electric and share identical electrical and mechanical specifications. The DF11-26DP-2DSA(24) is currently in active production status with ROHS3 compliance, making it the direct replacement for new designs and production runs.

SWR204-NRTN-D13-ST-GA from Sullins Connector Solutions is an alternative substitute when Hirose parts are unavailable. This part maintains the same connector configuration, pitch, and row spacing. However, the voltage rating is reduced to 50V compared to the 250V rating of the DF11 series, and the operating temperature minimum is -25°C versus -30°C. The current rating per contact is higher at 3A. This part is suitable only for applications where the lower voltage rating and narrower temperature range are acceptable.

Frequently Asked Questions (FAQ)

Q: Can DF11-26DP-2DSA(24) be used as a direct replacement for DF11-26DP-2DSA(20)?

A: Yes. Both parts share identical connector configuration, pitch, row spacing, electrical ratings, and operating temperature range. The primary difference is packaging and RoHS compliance status. The DF11-26DP-2DSA(24) is the recommended substitute.

Q: What are the limitations of using SWR204-NRTN-D13-ST-GA as a substitute?

A: The SWR204-NRTN-D13-ST-GA has a reduced voltage rating of 50V compared to the 250V rating of the DF11-26DP-2DSA(20). The operating temperature minimum is -25°C instead of -30°C. Applications requiring the full 250V rating or extended low-temperature operation must use the Hirose DF11 series.

Q: Are there packaging differences between the substitute parts?

A: Yes. The DF11-26DP-2DSA(20) and DF11-26DP-2DSA(24) differ in packaging format. The DF11-26DP-2DSA(24) is supplied in tube packaging, while the SWR204-NRTN-D13-ST-GA is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Do all substitute parts meet the same compliance standards?

A: The DF11-26DP-2DSA(24) and SWR204-NRTN-D13-ST-GA are both ROHS3 compliant and REACH unaffected. The original DF11-26DP-2DSA(20) is RoHS non-compliant. For applications requiring RoHS compliance, use either substitute part.

Q: What is the mechanical compatibility between these parts?

A: All three parts maintain the same 2.00mm pitch, 2-row configuration, and shrouded 4-wall design. Insulation height varies slightly: DF11 series at 0.260" (6.60mm) and SWR204 at 0.256" (6.50mm). This minor difference does not affect standard PCB mounting compatibility.
