Key Features
- 16-position rectangular receptacle with ultra-fine 0.4 mm pitch enabling high-density board stacking in mobile and wearable device applications
- Gold (Au) plated termination contacts and 100 mΩ maximum contact resistance for reliable signal integrity in high-cycle stacking applications
- Board stacking connector design eliminating flex cables between PCBs, reducing assembly steps and improving vibration resistance in compact electronic modules
Applications
The DF37NC-16DS-0.4V(51) is designed for board-to-board stacking applications in smartphones, wearable electronics, and compact IoT modules where ultra-fine 0.4 mm pitch is required to route 16 signals in a minimal footprint. Its female receptacle design mates with the corresponding Hirose DF37 series header, forming a reliable vertical or orthogonal stacking interface. The gold-plated termination contacts ensure consistent electrical performance across hundreds of mating cycles in devices subject to regular disassembly or field servicing.

Frequently Asked Questions
What is the contact pitch and circuit count of the DF37NC-16DS-0.4V(51), and how does this compare to standard board stacking connectors?
The DF37NC-16DS-0.4V(51) has a 0.4 mm contact pitch with 16 circuits in a rectangular receptacle configuration. This 0.4 mm pitch is significantly finer than the 0.5 mm or 1.0 mm pitch used in standard board stacking connectors, allowing the same 16 circuits to be routed in approximately 20% less board space. This density advantage is critical in mobile and wearable devices where PCB area is a premium resource.
How does the 100 mΩ maximum contact resistance of the DF37NC-16DS-0.4V(51) affect signal quality in high-speed interface connections?
The 100 mΩ maximum contact resistance of the DF37NC-16DS-0.4V(51) results in less than 1 mV of voltage drop per signal line at typical 10 mA logic signal currents. For high-speed digital interfaces operating at 100 MHz to 480 MHz (USB 2.0), this contact resistance is well within the impedance budget and does not introduce measurable signal degradation. Gold termination further reduces oxidation-driven resistance increase over the connector's service life.
When does a compact consumer electronics design benefit from using the DF37NC-16DS-0.4V(51) instead of a flex cable assembly between two PCBs?
The DF37NC-16DS-0.4V(51) board stacking connector is preferred over a flex cable when vertical PCB stacking distance is fixed at a defined standoff height, eliminating the need for flex routing and associated connectors at both ends of a flex cable. Removing the flex assembly reduces component count by 2 connectors and eliminates the flex cable BOM cost. Additionally, the board stacking approach improves vibration resistance in wearable devices, where repeated bending of flex cables over a 5-year product life can cause conductor fatigue at flex-to-connector junctions.
