DF11-28DP-2DSA(20) Equivalent & Substitute Parts

Part Overview

The DF11-28DP-2DSA(20) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting applications. This 28-position, 2-row connector operates at 2A per contact and 250V, with a 2.00mm pitch and shrouded 4-wall design. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the DF11-28DP-2DSA(20) is determined by the following critical parameters:

Connector type (Header), contact type (Male Pin), and position count (28 positions in 2 rows)
Pitch and row spacing (0.079" / 2.00mm)
Mounting method (Through Hole) and termination (Solder)
Shrouding configuration (Shrouded - 4 Wall)
Electrical ratings (minimum 2A current, minimum 250V voltage)
Operating temperature range compatibility (-30°C ~ 85°C or wider)
Flammability rating (UL94 V-0)

The DF11-28DP-2DSA(24) is a direct equivalent from the same manufacturer series with identical mechanical and electrical specifications. The SWR204-NRTN-D14-ST-GA from Sullins Connector Solutions provides functional equivalence with compatible pitch, position count, and shrouding, though with different electrical ratings and insulation material specifications.

Engineering Selection Recommendations

The DF11-28DP-2DSA(24) is the primary substitute for the obsolete DF11-28DP-2DSA(20). Both parts share identical mechanical and electrical specifications, with the key distinction being product status and RoHS compliance. The DF11-28DP-2DSA(24) is active in production and RoHS Compliant, making it the preferred choice for new designs and ongoing procurement.

The SWR204-NRTN-D14-ST-GA from Sullins Connector Solutions is an alternative substitute that maintains mechanical compatibility (pitch, position count, shrouding, and mounting type). However, this part has a reduced voltage rating of 50V compared to the 250V rating of the Hirose parts, and a lower minimum operating temperature of -25°C. The SWR204-NRTN-D14-ST-GA offers higher current capacity at 3A per contact. Selection of this part requires confirmation that the application voltage and temperature requirements do not exceed its specifications.

Frequently Asked Questions (FAQ)

Q: Can the DF11-28DP-2DSA(24) be used as a direct replacement for the DF11-28DP-2DSA(20)?

A: Yes. Both parts are from the Hirose DF11 series with identical pitch (2.00mm), position count (28), row configuration (2 rows), shrouding (4-wall), and electrical ratings (2A, 250V). The primary difference is product status and RoHS compliance.

Q: What are the key differences between the Hirose DF11-28DP-2DSA(24) and the Sullins SWR204-NRTN-D14-ST-GA?

A: Both maintain the same 2.00mm pitch, 28-position, 2-row configuration with shrouded 4-wall design. The Hirose part operates at 250V with 2A per contact, while the Sullins part operates at 50V with 3A per contact. The Hirose part supports -30°C to 85°C operation; the Sullins part supports -25°C to 85°C. Insulation material differs: Hirose uses PA/Nylon, Sullins uses PA66/Nylon 6/6.

Q: Is the SWR204-NRTN-D14-ST-GA suitable for applications requiring 250V operation?

A: No. The SWR204-NRTN-D14-ST-GA has a maximum voltage rating of 50V and is not suitable for applications requiring 250V operation.

Q: What is the packaging difference between these parts?

A: The DF11-28DP-2DSA(20) is supplied in standard packaging. The DF11-28DP-2DSA(24) is supplied in Tube packaging. The SWR204-NRTN-D14-ST-GA is supplied in Bulk packaging.

Q: Are all three parts RoHS compliant?

A: The DF11-28DP-2DSA(20) is RoHS non-compliant. The DF11-28DP-2DSA(24) is RoHS Compliant. The SWR204-NRTN-D14-ST-GA is ROHS3 Compliant.
