DF11-26DS-2DSA Equivalent & Substitute Parts

Part Overview

The DF11-26DS-2DSA is a 26-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 listed as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the DF11-26DS-2DSA is determined by strict alignment of the following critical parameters:

Connector configuration: 26 positions, 2 rows, 0.079" (2.00mm) pitch and row spacing
Mounting and termination: Through-hole mounting with solder capability
Electrical ratings: Minimum 2A current rating and 250V voltage rating
Environmental compliance: UL94 V-0 flammability rating and operating temperature range
Contact material and finish: Tin-plated contacts suitable for the application

Two substitute options are identified:

Direct Equivalent (DF11-26DS-2DSA(05)): An active-status variant of the same base product from Hirose Electric Co Ltd with identical mechanical and electrical specifications but improved RoHS3 compliance.

Cross-Manufacturer Substitute (SWR204-NRTN-D13-ST-GA): A header connector from Sullins Connector Solutions with matching pitch, position count, and row configuration. This part operates as a mating component (male pin header) to the receptacle and meets the same flammability and environmental standards.

Engineering Selection Recommendations

DF11-26DS-2DSA(05) is the preferred direct substitute. This part maintains identical mechanical and electrical specifications while offering active product status and ROHS3 compliance. The transition from phosphor bronze to brass contact material does not affect functional compatibility. Current inventory of 1245 units supports immediate procurement.

SWR204-NRTN-D13-ST-GA serves as a cross-manufacturer alternative when receptacle-to-header mating is required. The 50V voltage rating is a limiting factor for applications requiring the full 250V specification of the original part. The 3A per-contact current rating exceeds the 2A requirement. This option is suitable for lower-voltage applications and provides active product status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can DF11-26DS-2DSA(05) be used as a direct replacement for DF11-26DS-2DSA?

A: Yes. Both parts share identical pitch (0.079"), position count (26), row configuration (2 rows), mounting type (through-hole), and electrical ratings (2A, 250V). The primary difference is product status (active vs. obsolete) and RoHS compliance. The contact material change from phosphor bronze to brass does not affect electrical or mechanical compatibility.

Q: What is the key difference between the Hirose receptacle and the Sullins header?

A: The DF11-26DS-2DSA(05) is a receptacle (female socket) connector, while the SWR204-NRTN-D13-ST-GA is a header (male pin) connector. These are complementary mating components. The Sullins part operates at 50V maximum, compared to 250V for the Hirose receptacle, limiting its use to lower-voltage applications.

Q: Are there packaging differences between DF11-26DS-2DSA and DF11-26DS-2DSA(05)?

A: The original part lists packaging as unspecified, while DF11-26DS-2DSA(05) is supplied in bulk packaging. Both are through-hole mounted components with identical footprints and PCB compatibility.

Q: Does the operating temperature range affect substitution?

A: The DF11-26DS-2DSA and DF11-26DS-2DSA(05) both operate across -30°C to 85°C. The SWR204-NRTN-D13-ST-GA operates across -25°C to 85°C, a 5°C reduction at the lower limit. This difference is acceptable for most general-purpose applications but should be verified for extreme low-temperature environments.

Q: What compliance certifications apply to these parts?

A: All three parts carry UL94 V-0 flammability ratings. DF11-26DS-2DSA is RoHS non-compliant. Both DF11-26DS-2DSA(05) and SWR204-NRTN-D13-ST-GA are ROHS3 compliant. All parts are REACH unaffected and classified as EAR99 for export control purposes.
