Hybrid signal-power layout in a 0.80mm pitch receptacle
The 10159559-410221RLF: This ComboStak® receptacle carries 14 positions arranged as 10 signal contacts plus 4 power contacts in a 2-row configuration — the hybrid layout lets a single connector handle both logic-level signals and a modest power rail on the same board-to-board interface. Mated stacking heights from 9mm to 12mm are supported — one receptacle footprint covers four board-spacing requirements, which simplifies inventory if your design uses multiple stack heights across different board pairs.
Surface-mount assembly and board-retention features
Environmental range and flame rating
Voltage rating is 100 VDC, which is typical for signal-level board interconnects and low-power distribution; the connector is not intended for mains-voltage or high-isolation applications.
For applications requiring frequent field-service reconnects (hundreds of cycles), consider a connector with thicker gold plating (15µin or more); the 8µin layer here is better suited to one-time assembly or occasional rework.
Lifecycle and sourcing posture
How this compares to the 40-position ComboStak sibling
The closest functional sibling within the same series is 10159559-A30221RLF — a 40-position (30 signal + 10 power) version with the same 0.80mm pitch, same gold plating thickness, same stacking heights, and same SMT termination. The key difference is position count: 14 positions vs 40 positions. If your design needs more signal or power circuits on the same footprint pitch, the 40-position sibling is a drop-in replacement for the same stack height range.
