Key Features
- 24-position board-stacking receptacle with ultra-fine 0.4 mm pitch enabling high-density PCB-to-PCB interconnect in compact modules
- Gold-plated terminations with 100 mΩ maximum contact resistance for reliable signal and power connections across stacked boards
- DF37 series compatibility provides robust 51-type stacking height options for flexible board-stack configurations in mobile designs
- Female contact gender (receptacle) with rectangular contact pattern supports secure mating with matched DF37 plug headers
Applications
The DF37NC-24DS-0.4V(51) is designed for board-stacking applications in smartphones, tablets, wearables, and compact embedded modules where 24-channel interconnect at 0.4 mm pitch is needed within tight spatial constraints. The ultra-fine 0.4 mm pitch allows high signal density exceeding 60 contacts per centimeter of connector width, supporting parallel data buses, camera interfaces, and display signals in stacked PCB assemblies. Gold terminations ensure reliable connections over hundreds of mating cycles in consumer and industrial grade products.

Frequently Asked Questions
What is the pitch and contact count of the DF37NC-24DS-0.4V(51), and what signal density does this enable?
The DF37NC-24DS-0.4V(51) provides 24 contacts at a 0.4 mm pitch, enabling over 60 contacts per centimeter and fitting within a footprint of less than 10 mm width, making it well suited for high-density parallel bus and camera interface connections in compact mobile PCB stacking assemblies.
What contact resistance specification does the DF37NC-24DS-0.4V(51) guarantee for signal integrity?
The Hirose DF37NC-24DS-0.4V(51) specifies a maximum contact resistance of 100 mΩ per contact, ensuring signal voltage drop below 10 mV at 100 mA per pin, which is sufficient for high-speed digital I/O, MIPI CSI-2 camera, and DSI display interfaces operating in the 1.2 V to 3.3 V range.
Which board-stacking height does the 51 variant of the DF37NC-24DS-0.4V provide?
The '51' in DF37NC-24DS-0.4V(51) denotes the stacking height variant, providing a defined board-to-board separation that accommodates component height clearance between stacked PCBs. This allows system designers to select from multiple stacking heights in the DF37 family to match their enclosure and component tolerance requirements within millimeter-level precision.
When should a designer choose DF37NC-24DS-0.4V(51) over a 0.5 mm pitch alternative for the same 24-pin function?
At 0.4 mm pitch, the DF37NC-24DS-0.4V(51) occupies approximately 20% less connector width than a 0.5 mm pitch equivalent, saving roughly 1.2 mm of PCB edge length across 24 contacts. This size reduction is critical in smartphone and wearable PCBs where board dimensions are fixed within 0.5 mm tolerances.
