DF11-10DS-2DSA(01) Equivalent & Substitute Parts

Part Overview

The DF11-10DS-2DSA(01) is a 10-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, press-fit and solder termination options, and operates across -30°C to 85°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the DF11-10DS-2DSA(01) is determined by the following critical parameters:

Connector Configuration: 10-position, 2-row layout with 0.079" (2.00mm) pitch and row spacing
Mounting Interface: Through-hole termination compatibility
Electrical Performance: Minimum 2A current rating and 250V voltage rating
Environmental Compliance: UL94 V-0 flammability rating and operating temperature range of -30°C to 85°C
Physical Compatibility: Mated stacking heights and contact post length

Two substitute parts meet these criteria:

DF11-10DS-2DSA(06) — Direct series equivalent with identical mechanical and electrical specifications, differing only in contact post finish (tin vs. gold) and RoHS compliance status.

SWR204-NRTN-D05-ST-GA — Cross-manufacturer alternative with compatible pitch, position count, and through-hole mounting, though with different connector type (header vs. receptacle) and lower voltage rating (50V vs. 250V).

Engineering Selection Recommendations

DF11-10DS-2DSA(06) is the primary substitute for DF11-10DS-2DSA(01). Both parts are from the same DF11 series with identical mechanical dimensions, electrical ratings, and operating temperature range. The DF11-10DS-2DSA(06) is currently in active production status with ROHS3 compliance, addressing the obsolescence of the original part. The contact post finish differs (tin vs. nickel), but both maintain the required gold mating contact finish and equivalent electrical performance.

SWR204-NRTN-D05-ST-GA is a secondary alternative when DF11-10DS-2DSA(06) is unavailable. This Sullins connector maintains compatible pitch, position count, and through-hole mounting. However, it functions as a header (male pins) rather than a receptacle (female sockets), requiring mating with a compatible receptacle connector. The voltage rating is reduced to 50V, which may limit applicability in higher-voltage circuits. This part is suitable only for applications where the lower voltage specification and complementary connector type are acceptable.

Frequently Asked Questions (FAQ)

Q: Can DF11-10DS-2DSA(06) directly replace DF11-10DS-2DSA(01) without PCB modifications?

A: Yes. Both parts share identical mechanical dimensions, pitch spacing (0.079"), position count (10), row configuration (2 rows), and through-hole mounting footprint. No PCB layout changes are required.

Q: What is the significance of the contact post finish difference between DF11-10DS-2DSA(01) and DF11-10DS-2DSA(06)?

A: The original part uses nickel post finish (39.4µin thickness) while the substitute uses tin post finish (78.7µin thickness). Both finishes provide equivalent electrical conductivity and solderability. The tin finish in DF11-10DS-2DSA(06) offers improved solder wetting characteristics.

Q: Is SWR204-NRTN-D05-ST-GA compatible with existing DF11 receptacle connectors?

A: No. SWR204-NRTN-D05-ST-GA is a header connector with male pins, while DF11-10DS-2DSA(01) is a receptacle with female sockets. These are complementary connector types. The SWR204 requires a mating receptacle connector, not the DF11 receptacle itself.

Q: What are the voltage limitations when using SWR204-NRTN-D05-ST-GA?

A: SWR204-NRTN-D05-ST-GA is rated for 50V maximum, compared to 250V for the DF11 series. Applications requiring voltages above 50V must use DF11-10DS-2DSA(06) or equivalent DF11 receptacles.

Q: Are both substitute parts RoHS compliant?

A: Yes. DF11-10DS-2DSA(06) is ROHS3 compliant, and SWR204-NRTN-D05-ST-GA is ROHS3 compliant. The original DF11-10DS-2DSA(01) is RoHS non-compliant.

Q: What is the minimum operating temperature difference between the original and substitutes?

A: DF11-10DS-2DSA(01) and DF11-10DS-2DSA(06) both operate from -30°C. SWR204-NRTN-D05-ST-GA operates from -25°C, a 5°C higher minimum. Applications requiring operation below -25°C must use the DF11 series.
