Key Features
- Ultra-fine 0.5 mm pitch with 20-pin dual-row configuration enables extremely compact board-to-board stacking in space-constrained PCB designs
- Female receptacle with phosphor bronze contacts and gold (Au) over nickel (Ni) termination finish provides low-resistance mating and corrosion resistance
- RoHS compliant surface-mount construction supports lead-free manufacturing processes for consumer electronics and industrial applications
Applications
The DF12-20DS-0.5V(86) is designed for board-to-board stacking interconnects in smartphones, wearable devices, portable medical instruments, and compact industrial modules where fine pitch of 0.5 mm and 20 signal pins are needed in minimal PCB footprint. Its SMT receptacle format integrates directly into reflow soldering processes, enabling reliable stacking connections between two PCBs in space-critical assemblies.

Frequently Asked Questions
What is the pitch and pin count of the DF12-20DS-0.5V(86) and how does that affect PCB layout?
The DF12-20DS-0.5V(86) features a 0.5 mm pitch with 20 pins in a 2-row surface-mount receptacle. This ultra-fine 0.5 mm pitch significantly reduces the connector footprint compared to 1.0 mm pitch alternatives, enabling tight PCB layouts in mobile devices and wearables where every square millimeter of board space counts.
Which board-to-board stacking height does the DF12-20DS-0.5V(86) support and what mating connector is recommended?
The DF12-20DS-0.5V(86) is part of the Hirose DF12 series, which supports multiple stacking heights typically ranging from 0.5 mm to 5 mm. It mates with corresponding DF12 plug headers; the 86 in the part number references a specific stacking height variant. Always confirm the mating DF12 plug height matches the required board separation of your 2-row, 20-pin application.
Is the DF12-20DS-0.5V(86) suitable for automotive or harsh-environment designs?
The DF12-20DS-0.5V(86) is RoHS compliant and uses phosphor bronze contacts with gold over nickel plating, providing solid corrosion resistance. However, it is primarily rated for consumer and light industrial applications. For automotive Grade 1 environments requiring AEC-Q200 qualification and extended temperature ranges beyond -40°C to +85°C, dedicated automotive-rated connectors should be evaluated.
How does the 20-pin DF12-20DS-0.5V(86) compare to higher pin-count DF12 variants for modular design scalability?
The 20-pin DF12-20DS-0.5V(86) at 0.5 mm pitch suits interfaces requiring 20 signals in a minimal footprint. The DF12 series is available in pin counts from as few as 2 pins up to 60 pins or more, all sharing the same 0.5 mm pitch and 2-row SMT configuration, so designers can scale from 20 pins to higher counts while maintaining the same board stacking architecture.
