DF11-12DP-2DSA(20) Equivalent & Substitute Parts

Part Overview

The DF11-12DP-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 12-position, 2-row connector operates at 2A current rating and 250V voltage rating with a 0.079" (2.00mm) pitch configuration. The part is currently obsolete, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF11-12DP-2DSA(20) is determined by the following critical parameters:

• Connector geometry: 12 positions, 2 rows, 0.079" (2.00mm) pitch and row spacing
• Contact configuration: Male pin, square contact shape
• Mounting method: Through-hole solder termination with detent lock fastening
• Shrouding: 4-wall shrouded design
• Electrical performance: Current and voltage ratings must meet or exceed 2A and 250V respectively
• Environmental compliance: UL94 V-0 flammability rating and MSL 1 moisture sensitivity

The identified substitute parts maintain these core parameters while offering improved product status (active vs. obsolete) and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

DF11-12DP-2DSA(24) is the primary substitute for the obsolete DF11-12DP-2DSA(20). Both parts are manufactured by Hirose Electric Co Ltd within the same DF11 series and maintain identical electrical and mechanical specifications. The DF11-12DP-2DSA(24) is currently in active production status with ROHS3 compliance, providing direct compatibility with existing PCB designs and assembly processes. This option is recommended for applications requiring continuity with the original Hirose platform.

1-1470109-2 (TE Connectivity AMPMODU series) and SWR204-NRTN-D06-ST-GA (Sullins SWR204 series) are cross-manufacturer alternatives that satisfy the core geometric and electrical requirements. Both parts feature identical pitch, row spacing, position count, and mounting configuration. However, these alternatives present the following considerations:

• The 1-1470109-2 operates at 100VDC maximum, which is below the original 250V rating
• The SWR204-NRTN-D06-ST-GA operates at 50V maximum, which is significantly below the original 250V rating
• Both alternatives feature improved current ratings (3A) compared to the original 2A specification
• Both alternatives are RoHS compliant and actively produced

Selection between these alternatives depends on application voltage requirements. For applications operating below 50V, the SWR204-NRTN-D06-ST-GA provides a viable cross-manufacturer option. For applications requiring voltage operation between 50V and 100V, the 1-1470109-2 is suitable. For applications requiring the full 250V rating of the original part, the DF11-12DP-2DSA(24) is the only listed substitute that maintains this specification.

Frequently Asked Questions (FAQ)

Q: Can the DF11-12DP-2DSA(24) be used as a direct replacement for the DF11-12DP-2DSA(20)?

A: Yes. Both parts share identical connector geometry, contact configuration, pitch spacing, and electrical ratings. The primary difference is product status (active vs. obsolete) and RoHS compliance certification. PCB footprints and mating connector designs are fully compatible.

Q: What is the significance of the voltage rating differences between substitutes?

A: The original DF11-12DP-2DSA(20) is rated for 250V operation. The 1-1470109-2 is rated for 100VDC maximum, and the SWR204-NRTN-D06-ST-GA is rated for 50V maximum. These ratings define the maximum voltage that can be safely applied across the connector contacts. Applications exceeding these voltage limits must use the DF11-12DP-2DSA(24) to maintain the original 250V specification.

Q: Are the cross-manufacturer alternatives (TE Connectivity and Sullins) mechanically compatible with existing PCB designs?

A: Yes. All substitute parts maintain the identical 0.079" (2.00mm) pitch, 2-row configuration, 12-position layout, and through-hole mounting footprint. PCB hole patterns and spacing are fully compatible. However, mating connector compatibility should be verified with the specific mating connector manufacturer, as some mating connectors may be series-specific.

Q: What is the difference between the packaging options listed?

A: The DF11-12DP-2DSA(20) is listed with unspecified packaging. The DF11-12DP-2DSA(24) is supplied in tube packaging. The 1-1470109-2 and SWR204-NRTN-D06-ST-GA are supplied in bulk packaging. Packaging affects handling, storage, and automated assembly processes but does not impact electrical or mechanical performance.

Q: Why do the cross-manufacturer alternatives have higher current ratings (3A) than the original (2A)?

A: Current rating is determined by contact material, contact geometry, and thermal design. The TE Connectivity and Sullins alternatives feature brass contacts with tin finish similar to the original part but may have different contact cross-sectional areas or thermal characteristics that support higher current capacity. The original 2A rating remains the limiting factor for applications designed around the DF11-12DP-2DSA(20).

Q: Are all substitute parts RoHS compliant?

A: The DF11-12DP-2DSA(20) is RoHS non-compliant. The DF11-12DP-2DSA(24) is ROHS3 compliant. The 1-1470109-2 is RoHS compliant. The SWR204-NRTN-D06-ST-GA is ROHS3 compliant. For applications requiring RoHS compliance, the DF11-12DP-2DSA(24), 1-1470109-2, or SWR204-NRTN-D06-ST-GA are suitable options.
