DF11-4DP-2DSA(20) Equivalent & Substitute Parts

Part Overview

The DF11-4DP-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 4 positions arranged in 2 rows at 2.00mm pitch, utilizing shrouded 4-wall construction with detent lock fastening. The part is currently classified as obsolete, necessitating identification of equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF11-4DP-2DSA(20) is determined by the following critical parameters:

• Connector type, contact type, and orientation (Header, Male Pin, Vertical)
• Pitch and row spacing (0.079" / 2.00mm)
• Position count and row configuration (4 positions, 2 rows)
• Mounting method (Through Hole)
• Shrouding design (Shrouded - 4 Wall)
• Fastening mechanism (Detent Lock)
• Electrical ratings (minimum 2A current, minimum 250V voltage)
• Operating temperature range compatibility (-30°C ~ 85°C minimum)
• Flammability compliance (UL94 V-0)

The identified substitutes maintain these core parameters while differing in product status, packaging, and secondary specifications such as insulation material composition and contact finish thickness.

Parameter Comparison

Engineering Selection Recommendations

DF11-4DP-2DSA(24) is the primary direct substitute. This part is manufactured by Hirose Electric Co Ltd under the same DF11 series and maintains identical electrical and mechanical specifications to the obsolete DF11-4DP-2DSA(20). The primary distinction is product status: DF11-4DP-2DSA(24) is active and ROHS3 compliant, whereas the original part is obsolete and RoHS non-compliant. Packaging differs (Tube versus unspecified), and contact finish thickness on the mating surface is specified at 39.4µin (1.00µm) for the substitute. This part is recommended for direct replacement in new designs and ongoing production.

SWR204-NRTN-D02-ST-GA, manufactured by Sullins Connector Solutions, is an alternative substitute that maintains core mechanical and mating parameters. However, this part exhibits the following deviations: voltage rating is reduced to 50V (versus 250V), current rating is increased to 3A per contact (versus 2A), operating temperature minimum is -25°C (versus -30°C), and insulation material is specified as Polyamide (PA66) Nylon 6/6 (versus Polyamide (PA) Nylon). This part is ROHS3 compliant and active. Selection of this substitute requires verification that the reduced voltage rating and modified operating temperature range are acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can DF11-4DP-2DSA(24) be used as a direct replacement for DF11-4DP-2DSA(20)?

A: Yes. Both parts share identical connector type, pitch, position count, row configuration, mounting method, shrouding, fastening mechanism, and electrical ratings. The primary difference is product status and RoHS compliance. DF11-4DP-2DSA(24) is the recommended substitute for the obsolete DF11-4DP-2DSA(20).

Q: What are the limitations of using SWR204-NRTN-D02-ST-GA as a substitute?

A: The SWR204-NRTN-D02-ST-GA has a reduced voltage rating of 50V compared to the 250V rating of the original part. The minimum operating temperature is -25°C instead of -30°C. These parameters must be verified against application requirements before selection.

Q: Are there packaging differences between the substitute parts?

A: Yes. DF11-4DP-2DSA(24) is supplied in Tube packaging, while SWR204-NRTN-D02-ST-GA is supplied in Bulk packaging. Packaging selection may affect procurement, handling, and storage procedures.

Q: Do the substitute parts meet RoHS compliance requirements?

A: DF11-4DP-2DSA(24) and SWR204-NRTN-D02-ST-GA are both ROHS3 compliant. The original DF11-4DP-2DSA(20) is RoHS non-compliant. If RoHS compliance is required, either substitute part is acceptable.

Q: What is the difference in insulation material between the parts?

A: The original DF11-4DP-2DSA(20) and substitute DF11-4DP-2DSA(24) use Polyamide (PA) Nylon. The SWR204-NRTN-D02-ST-GA uses Polyamide (PA66) Nylon 6/6, which is a more specific polyamide formulation. Both materials meet UL94 V-0 flammability requirements.

Q: Are the mating and post contact lengths identical across all three parts?

A: Contact length specifications are not uniformly provided across all parts. The original and direct substitute (DF11-4DP-2DSA(24)) specify contact length - mating at 0.118" (3.00mm) and contact length - post at 0.118" (3.00mm). The SWR204-NRTN-D02-ST-GA specifies contact length - post at 0.118" (3.00mm) but does not provide contact length - mating specification.
