DF11-12DS-2DSA(01) Equivalent & Substitute Parts

Part Overview

The DF11-12DS-2DSA(01) 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 gold-plated mating contacts, through-hole mounting, and friction lock fastening. The part is currently obsolete, making identification of suitable substitutes essential for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DF11-12DS-2DSA(01) is determined by the following critical parameters:

Direct Compatibility Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (12)
• Pitch spacing (0.079" / 2.00mm)
• Row configuration (2 rows with 0.079" spacing)
• Mounting method (Through Hole)
• Electrical ratings (minimum 2A current, 250V voltage)
• Operating temperature range (-30°C ~ 85°C)

Substitute Categories:

Category 1: Direct Manufacturer Equivalent – DF11-12DS-2DSA(06) is a direct Hirose Electric equivalent with identical mechanical and electrical specifications. The primary difference is product status (Active vs. Obsolete) and post-contact finish (Tin vs. Nickel), with no impact on mating interface compatibility.

Category 2: Cross-Manufacturer Substitute – SWR204-NRTN-D06-ST-GA from Sullins Connector Solutions is a header connector with complementary pin configuration. This part functions as the mating component (male pins vs. female sockets) and shares the same 2.00mm pitch and 12-position, 2-row layout. Substitution requires pairing with the appropriate mating receptacle or cable assembly.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Receptacle Function):

DF11-12DS-2DSA(06) is the primary substitute for DF11-12DS-2DSA(01). Both parts are Hirose Electric DF11 series receptacles with identical mechanical interfaces and electrical ratings. The DF11-12DS-2DSA(06) is currently in active production status with ROHS3 compliance, addressing the obsolescence of the original part. The post-contact finish difference (Tin vs. Nickel) does not affect mating interface performance. This substitute is suitable for direct board-level replacement without design modification.

For System-Level Integration:

SWR204-NRTN-D06-ST-GA from Sullins Connector Solutions provides an alternative interconnect solution with the same pitch and position count. This header connector is designed as a mating component and is suitable for applications requiring a complementary male-pin connector. Selection of this part requires verification that the existing system design accommodates a header-based connection scheme. The voltage rating of 50V is lower than the original specification; applications exceeding this rating require design review.

Compliance Considerations:

Both substitute parts carry ROHS3 compliance certification, supporting modern manufacturing and environmental standards. The original DF11-12DS-2DSA(01) is RoHS non-compliant; migration to either substitute part aligns with current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can DF11-12DS-2DSA(06) be used as a direct drop-in replacement for DF11-12DS-2DSA(01)?

A: Yes. Both parts are Hirose Electric DF11 series receptacles with identical 12-position, 2-row configuration at 0.079" (2.00mm) pitch. Mechanical and electrical specifications are equivalent. The parts are mechanically and electrically interchangeable at the board level.

Q: What is the difference between the post-contact finishes (Nickel vs. Tin) in DF11-12DS-2DSA(01) and DF11-12DS-2DSA(06)?

A: Post-contact finish refers to the plating on the solder tail or press-fit post. This does not affect the mating interface performance. Both finishes provide adequate solderability and mechanical strength for through-hole mounting. Selection between them is determined by PCB assembly process requirements and solder compatibility specifications.

Q: Is SWR204-NRTN-D06-ST-GA compatible with DF11-12DS-2DSA(01)?

A: SWR204-NRTN-D06-ST-GA is a header connector (male pins) with the same 2.00mm pitch and 12-position, 2-row layout. It is designed to mate with receptacle connectors of matching pitch and configuration. Compatibility depends on the system design: if the original design uses a receptacle connector on the board, a mating header connector on the cable or daughter board would be required. Direct one-to-one replacement is not applicable; system-level design review is necessary.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: connector type (Receptacle), contact type (Female Socket), number of positions (12), pitch spacing (0.079" / 2.00mm), row configuration (2 rows), mounting method (Through Hole), and electrical ratings (minimum 2A current, 250V voltage). Deviations in any of these parameters indicate incompatibility.

Q: Does the packaging difference between the main part and DF11-12DS-2DSA(06) affect compatibility?

A: No. Packaging (Tray vs. other formats) is a logistics and handling specification only. It does not affect the electrical or mechanical performance of the connector itself. Both parts are functionally identical.

Q: What is the voltage rating limitation of SWR204-NRTN-D06-ST-GA?

A: SWR204-NRTN-D06-ST-GA has a 50V voltage rating, compared to 250V for the original DF11-12DS-2DSA(01). Applications requiring voltages above 50V cannot use this substitute without design modification or voltage derating analysis.
