DF11-8DS-2DSA Equivalent & Substitute Parts

Part Overview

The DF11-8DS-2DSA is an 8-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, tin-plated contacts, 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 for the DF11-8DS-2DSA is determined by the following critical parameters:

Pitch and Position Compatibility: All substitute parts maintain 0.079" (2.00mm) pitch with 8 positions in a 2-row configuration
Mounting Interface: Through-hole mounting with compatible post lengths (0.118" / 3.00mm)
Electrical Ratings: Current and voltage ratings must meet or exceed the original specification
Connector Geometry: Insulation height, contact shape, and mated stacking heights must be compatible with existing PCB layouts
Material and Compliance: UL94 V-0 flammability rating and RoHS compliance status

The DF11-8DS-2DSA(05) is a direct manufacturer variant with identical mechanical and electrical specifications but active product status. The header connectors (1470109-8, B8B-PHDSS(LF)(SN), SWR204-NRTN-D04-ST-GA) are mating counterparts with male pins designed to interface with receptacle connectors.

Engineering Selection Recommendations

Direct Receptacle Replacement: DF11-8DS-2DSA(05) is the primary substitute for the obsolete DF11-8DS-2DSA. Both are Hirose receptacle connectors with identical mechanical and electrical specifications. The DF11-8DS-2DSA(05) is currently in active production with ROHS3 compliance, making it suitable for new designs and legacy system maintenance.

Mating Header Connectors: The 1470109-8 (TE Connectivity), B8B-PHDSS(LF)(SN) (JST), and SWR204-NRTN-D04-ST-GA (Sullins) are header connectors designed to mate with receptacle connectors of this pitch and position configuration. These are used when the mating connector side requires replacement or upgrade.

Compliance Considerations: All active substitute parts carry ROHS3 compliance certification. The original DF11-8DS-2DSA is RoHS non-compliant; designs requiring RoHS compliance must transition to DF11-8DS-2DSA(05) or equivalent compliant alternatives.

Voltage and Current Derating: The header connectors (1470109-8, B8B-PHDSS(LF)(SN), SWR204-NRTN-D04-ST-GA) provide higher current ratings (3A) than the original receptacle (2A). However, SWR204-NRTN-D04-ST-GA operates at 50V maximum, which is below the original 250V specification and requires application review before selection.

Frequently Asked Questions (FAQ)

Q: Can DF11-8DS-2DSA(05) be used as a direct replacement for DF11-8DS-2DSA?

A: Yes. Both connectors are Hirose DF11 series receptacles with identical 8-position, 2-row configuration at 0.079" (2.00mm) pitch. Mechanical and electrical specifications are equivalent. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What is the difference between receptacle and header connectors in this product family?

A: The DF11-8DS-2DSA is a receptacle connector with female sockets designed to receive male pins. The header connectors (1470109-8, B8B-PHDSS(LF)(SN), SWR204-NRTN-D04-ST-GA) are male pin connectors designed to mate with receptacles. Both types are required for complete board-to-board or cable connections.

Q: Are the header connectors interchangeable with each other?

A: The three header connectors share identical pitch (0.079" / 2.00mm), position count (8), row configuration (2), and mounting type (through-hole). They are mechanically compatible for mating with the DF11-8DS-2DSA receptacle. Differences in current rating, voltage rating, and contact material should be evaluated against application requirements.

Q: What packaging options are available?

A: DF11-8DS-2DSA(05) is supplied in Tray packaging. The header connectors are supplied in Bulk packaging (1470109-8, B8B-PHDSS(LF)(SN), SWR204-NRTN-D04-ST-GA).

Q: Does the insulation height difference affect compatibility?

A: The DF11-8DS-2DSA receptacle has an insulation height of 0.244" (6.20mm), while the header connectors measure 0.256" (6.50mm). This 0.012" (0.30mm) difference is within typical PCB layout tolerances and does not prevent mating. However, PCB design should account for this variation in stacking height calculations.

Q: Which substitute is recommended for new designs?

A: DF11-8DS-2DSA(05) for receptacle applications and B8B-PHDSS(LF)(SN) for header applications are recommended for new designs. Both are active products with ROHS3 compliance and 250V voltage rating, providing the broadest application compatibility.
