Substitute Part Grouping Explanation

Substitution for the DF11-28DS-2DSA is determined by strict alignment of the following critical parameters:

Direct Substitutes (Same Connector Type - Receptacle):

Connector type must be receptacle with female socket contacts
Pitch spacing must be 0.079" (2.00mm) in both mating and row directions
Position count must be 28 with 2-row configuration
Mounting must be through-hole with compatible termination methods
Contact finish must be tin-plated
Operating temperature range must encompass or match -30°C ~ 85°C
Voltage and current ratings must meet or exceed 250V and 2A specifications

Cross-Type Substitutes (Header Connectors):

Header connectors with male pin contacts can mate with DF11-28DS-2DSA receptacles
Pitch spacing, position count, and row configuration must remain identical
Through-hole mounting and solder termination are required
Tin-plated contacts on mating surfaces ensure compatibility
Operating temperature and flammability ratings must be compatible

Engineering Selection Recommendations

DF11-28DS-2DSA(05) is the primary direct substitute for the obsolete DF11-28DS-2DSA. Both parts are manufactured by Hirose Electric Co Ltd within the DF11 series and maintain identical electrical and mechanical specifications. The key distinction is product status: DF11-28DS-2DSA(05) is active and ROHS3 compliant, whereas the original part is obsolete and RoHS non-compliant. This makes DF11-28DS-2DSA(05) the preferred choice for new designs and ongoing production requiring regulatory compliance.

SWR204-NRTN-D14-ST-GA manufactured by Sullins Connector Solutions is a cross-type substitute suitable for applications where a mating header connector is required. This part maintains the critical pitch spacing (0.079" / 2.00mm), position count (28), row configuration (2), and through-hole mounting. However, the voltage rating is 50V compared to the original 250V, and the operating temperature minimum is -25°C versus -30°C. Selection of this part requires confirmation that the application voltage and temperature requirements do not exceed these specifications. The part is active and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can DF11-28DS-2DSA(05) be used as a direct replacement for DF11-28DS-2DSA?

A: Yes. Both parts are receptacle connectors with identical pitch spacing (0.079" / 2.00mm), 28-position configuration, 2-row layout, through-hole mounting, and electrical ratings (250V, 2A). The primary difference is product status and compliance: DF11-28DS-2DSA(05) is active and ROHS3 compliant, making it suitable for new designs and production environments requiring regulatory adherence.

Q: What is the mating interface for the DF11-28DS-2DSA receptacle?

A: The DF11-28DS-2DSA receptacle mates with male pin headers or connectors featuring 0.079" (2.00mm) pitch spacing, 28 positions, and 2-row configuration. The SWR204-NRTN-D14-ST-GA header from Sullins Connector Solutions is a compatible mating connector.

Q: Are there voltage or temperature limitations when using SWR204-NRTN-D14-ST-GA as a substitute?

A: Yes. The SWR204-NRTN-D14-ST-GA has a voltage rating of 50V and operating temperature range of -25°C ~ 85°C. The original DF11-28DS-2DSA specifies 250V and -30°C ~ 85°C. Applications requiring higher voltage or lower temperature operation must use DF11-28DS-2DSA(05) or equivalent receptacles rated for those conditions.

Q: What are the packaging differences between substitute parts?

A: DF11-28DS-2DSA(05) and SWR204-NRTN-D14-ST-GA are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection should be based on application requirements and supply chain availability.

Q: Is the contact material difference between DF11-28DS-2DSA and DF11-28DS-2DSA(05) significant?

A: The original part specifies phosphor bronze contacts, while DF11-28DS-2DSA(05) uses brass contacts. Both materials are tin-plated and suitable for the specified electrical ratings and operating conditions. This material difference does not affect functional compatibility or performance in standard applications.
