DF11-12DS-2DSA Equivalent & Substitute Parts

Part Overview

The DF11-12DS-2DSA is a 12-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 system support and new design implementations.

Substitute Part Grouping Explanation

Substitution for the DF11-12DS-2DSA is determined by the following critical parameters: connector type (receptacle vs. header), contact type (female socket vs. male pin), number of positions (12), pitch spacing (0.079" / 2.00mm), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (through hole), and electrical ratings (current and voltage capacity).

The identified substitutes fall into two categories:

Direct Equivalent (Same Connector Type): DF11-12DS-2DSA(05) maintains identical mechanical and electrical specifications as the main part, with the primary distinction being active product status and RoHS3 compliance.

Functional Substitute (Complementary Connector Type): SWR204-NRTN-D06-ST-GA is a header connector (male pin) that mates with receptacle connectors of matching pitch and position count. This substitute is applicable in systems where the mating connector type is interchangeable or where header-based interconnection is preferred.

Engineering Selection Recommendations

For Direct Replacement: DF11-12DS-2DSA(05) is the primary equivalent, offering identical mechanical and electrical specifications with the advantage of active product status and ROHS3 compliance. This part is suitable for applications requiring direct form-fit-function compatibility with the obsolete DF11-12DS-2DSA.

For System Redesign: SWR204-NRTN-D06-ST-GA serves as a functional substitute when connector type flexibility exists in the design. This header connector maintains pitch and position compatibility but operates at reduced voltage (50V vs. 250V) and lower temperature minimum (-25°C vs. -30°C). Current capacity is higher at 3A per contact. Selection of this substitute requires verification that system voltage and temperature requirements do not exceed the specified ratings.

Frequently Asked Questions (FAQ)

Q: Can DF11-12DS-2DSA(05) be used as a direct replacement for DF11-12DS-2DSA?

A: Yes. Both parts are 12-position receptacle connectors with identical pitch (0.079" / 2.00mm), row spacing, mounting type, and electrical ratings. The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the key difference between DF11-12DS-2DSA and SWR204-NRTN-D06-ST-GA?

A: DF11-12DS-2DSA is a receptacle (female socket) connector, while SWR204-NRTN-D06-ST-GA is a header (male pin) connector. Both share 12 positions and 0.079" (2.00mm) pitch spacing. The SWR204 operates at lower voltage (50V vs. 250V) and lower minimum temperature (-25°C vs. -30°C).

Q: Can SWR204-NRTN-D06-ST-GA replace DF11-12DS-2DSA in all applications?

A: No. SWR204-NRTN-D06-ST-GA is a header connector and cannot directly replace a receptacle connector in the same socket. It is suitable only for applications where the mating connector type can be changed or where header-based interconnection is acceptable. Voltage rating (50V maximum) must be verified against system requirements.

Q: What packaging options are available?

A: DF11-12DS-2DSA(05) is supplied in bulk packaging. SWR204-NRTN-D06-ST-GA is also supplied in bulk packaging.

Q: Are there temperature or current limitations when using SWR204-NRTN-D06-ST-GA?

A: Yes. SWR204-NRTN-D06-ST-GA operates from -25°C to 85°C (vs. -30°C to 85°C for DF11-12DS-2DSA) and supports 3A per contact (vs. 2A for DF11-12DS-2DSA). Voltage rating is 50V maximum, significantly lower than the 250V rating of DF11-12DS-2DSA.
