DF11-22DS-2DSA Equivalent & Substitute Parts

Part Overview

The DF11-22DS-2DSA is a 22-position receptacle connector manufactured by Hirose Electric Co Ltd, designed for board-to-board or cable applications with 0.079" (2.00mm) pitch spacing. This connector features through-hole mounting with press-fit and solder termination options, tin-plated contacts, and operates across -30°C to 85°C. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the DF11-22DS-2DSA is determined by the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (22), mating pitch (0.079" / 2.00mm), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (through hole), and electrical ratings (2A current, 250V voltage). Parts meeting these specifications are considered direct or functional equivalents.

Two substitute parts are identified:

Direct Equivalent: DF11-22DS-2DSA(05) maintains identical mechanical and electrical specifications while offering active product status and RoHS3 compliance.

Functional Substitute: SWR204-NRTN-D11-ST-GA is a header connector (male pin) from Sullins Connector Solutions that shares the same pitch, position count, row configuration, and through-hole mounting. This part functions as a mating counterpart in board-to-cable applications.

Engineering Selection Recommendations

DF11-22DS-2DSA(05) is the primary substitute for the obsolete DF11-22DS-2DSA. Both parts are manufactured by Hirose Electric Co Ltd and share identical mechanical and electrical specifications. The key advantage of DF11-22DS-2DSA(05) is its active product status and ROHS3 compliance, making it suitable for new designs and applications requiring regulatory compliance. Packaging differs (tray versus unspecified), but this does not affect functional compatibility.

SWR204-NRTN-D11-ST-GA serves as a functional substitute when a mating header connector is required. As a male pin header with identical pitch and position configuration, it pairs with receptacle connectors in board-to-cable applications. However, note that the voltage rating (50V) is significantly lower than the DF11-22DS-2DSA (250V), and the operating temperature minimum is -25°C compared to -30°C. Selection of this part requires verification that application voltage and temperature requirements do not exceed these limits.

Frequently Asked Questions (FAQ)

Q: Can DF11-22DS-2DSA(05) be used as a direct replacement for DF11-22DS-2DSA?

A: Yes. Both parts share identical connector type, contact type, position count, pitch, row configuration, mounting type, and electrical ratings. The primary difference is product status (active versus obsolete) and RoHS compliance. DF11-22DS-2DSA(05) is the recommended choice for new applications.

Q: What is the difference between DF11-22DS-2DSA and SWR204-NRTN-D11-ST-GA?

A: DF11-22DS-2DSA is a receptacle (female socket) connector, while SWR204-NRTN-D11-ST-GA is a header (male pin) connector. Both share the same pitch (0.079" / 2.00mm), position count (22), and row configuration (2 rows). These parts are designed to mate with each other in board-to-cable applications. The SWR204 has lower voltage (50V) and current (3A per contact) ratings and a narrower operating temperature range (-25°C to 85°C).

Q: Are there packaging differences between the substitute parts?

A: Yes. DF11-22DS-2DSA is supplied in unspecified packaging, DF11-22DS-2DSA(05) is supplied in trays, and SWR204-NRTN-D11-ST-GA is supplied in bulk. Packaging does not affect electrical or mechanical compatibility but may impact handling, storage, and procurement workflows.

Q: What compliance certifications apply to these connectors?

A: DF11-22DS-2DSA is RoHS non-compliant. Both DF11-22DS-2DSA(05) and SWR204-NRTN-D11-ST-GA are ROHS3 compliant. All three parts carry UL94 V-0 material flammability ratings and are REACH unaffected. ECCN classification is EAR99 for all parts.

Q: Can SWR204-NRTN-D11-ST-GA be used in applications requiring 250V operation?

A: No. SWR204-NRTN-D11-ST-GA has a maximum voltage rating of 50V, which is insufficient for applications requiring 250V operation. Use DF11-22DS-2DSA or DF11-22DS-2DSA(05) for high-voltage applications.
