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

Part Overview

The DF11-20DP-2DSA(20) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole board-to-board or cable applications. This 20-position, 2-row connector operates at 2A current rating and 250V voltage rating with a 0.079" (2.00mm) pitch configuration. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

The identified substitute parts maintain these core electrical and mechanical specifications, ensuring direct functional compatibility in applications designed for the DF11-20DP-2DSA(20).

Parameter Comparison

Engineering Selection Recommendations

Hirose DF11 Series Substitutes (DF11-20DP-2DSA(24) and DF11-20DP-2DSA(01)):

These parts are direct Hirose DF11 series alternatives with identical mechanical and electrical specifications to the obsolete DF11-20DP-2DSA(20). Both are active products with RoHS3 compliance. The DF11-20DP-2DSA(24) features tin contact finish and is available in tube packaging. The DF11-20DP-2DSA(01) features gold contact finish on mating surfaces and is available in bulk packaging. Selection between these two depends on contact finish requirements and packaging preferences for production workflows.

Cross-Manufacturer Substitutes (2-1470109-0 and SWR204-NRTN-D10-ST-GA):

The TE Connectivity 2-1470109-0 (AMPMODU series) and Sullins SWR204-NRTN-D10-ST-GA maintain core mechanical compatibility with identical pitch, position count, and row configuration. Both are active products with RoHS compliance. These alternatives present higher current ratings (3A) compared to the original 2A specification. The TE part operates at 100VDC maximum, while the Sullins part operates at 50V maximum, both lower than the original 250V rating. These voltage and current differences require application-level verification to confirm suitability for specific circuit requirements.

Compliance Considerations:

The original DF11-20DP-2DSA(20) is RoHS non-compliant. All identified substitutes are RoHS compliant (RoHS3 or RoHS Compliant status), supporting modern manufacturing and environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can DF11-20DP-2DSA(24) directly replace DF11-20DP-2DSA(20)?

A: Yes. Both parts are Hirose DF11 series connectors with identical electrical and mechanical specifications. The primary difference is product status (active vs. obsolete) and packaging format (tube vs. original packaging). The DF11-20DP-2DSA(24) is the recommended direct replacement.

Q: What is the difference between DF11-20DP-2DSA(24) and DF11-20DP-2DSA(01)?

A: Both are active Hirose DF11 series alternatives with identical core specifications. The DF11-20DP-2DSA(24) has tin contact finish on mating surfaces with 1.00µm thickness. The DF11-20DP-2DSA(01) has gold contact finish on mating surfaces with 0.203µm thickness. Gold finish provides enhanced corrosion resistance and contact reliability in certain applications. Packaging differs: DF11-20DP-2DSA(24) is supplied in tube format, while DF11-20DP-2DSA(01) is supplied in bulk.

Q: Are TE Connectivity 2-1470109-0 and Sullins SWR204-NRTN-D10-ST-GA fully compatible with the original part?

A: These parts maintain mechanical compatibility through identical pitch (0.079"), position count (20), row configuration (2 rows), and shrouding design. However, electrical ratings differ: both offer 3A current rating versus the original 2A, and voltage ratings are 100VDC (TE) and 50V (Sullins) versus the original 250V. Applications operating within these lower voltage and current parameters can use these alternatives. Applications requiring the full 250V rating must use Hirose DF11 series substitutes.

Q: What packaging options are available for substitutes?

A: DF11-20DP-2DSA(24) is supplied in tube packaging. DF11-20DP-2DSA(01), 2-1470109-0, and SWR204-NRTN-D10-ST-GA are supplied in bulk packaging. Packaging selection depends on production volume requirements and handling procedures.

Q: Are all substitutes RoHS compliant?

A: Yes. All identified substitutes are RoHS compliant (RoHS3 Compliant or RoHS Compliant status). The original DF11-20DP-2DSA(20) is RoHS non-compliant. This compliance improvement supports modern manufacturing standards and environmental regulations.

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

A: Hirose DF11 series substitutes (DF11-20DP-2DSA(24) and DF11-20DP-2DSA(01)) operate from -30°C to 85°C, matching the original part. TE Connectivity 2-1470109-0 and Sullins SWR204-NRTN-D10-ST-GA operate from -25°C to 85°C, a 5°C reduction at the lower temperature limit. Applications requiring operation below -25°C must use Hirose DF11 series alternatives.
