Key Features
- 28-way 4-row through-hole socket at 2 mm pitch with 14 mm stacking height enables precise board-to-board gap control in stacked PCB assemblies
- 4-row contact arrangement (S24P4) provides high signal density in a 1.631" x 0.4" footprint for multi-layer board stacks
- Through-hole mounting delivers superior mechanical retention compared to SMT alternatives, supporting stacking assemblies under vibration up to 15 g
- Short 3-week factory lead time supports rapid prototyping and low-to-medium volume production scheduling for board stacking designs
Applications
The MPSC-02-24-02-7.70-01-L-V board stacking socket is used in multi-board electronic systems where a precise 14 mm inter-board spacing is required, such as industrial PLC rack modules, embedded computing stacks, and server blade sub-assemblies. Its 4-row 2 mm pitch through-hole design provides 28-way connectivity with mechanical robustness for environments with shock and vibration. The part suits modular instrument platforms where interchangeable daughter boards must plug into a common motherboard backplane with consistent 14 mm Z-axis clearance for cabling and airflow.

Frequently Asked Questions
What stacking height and pin count does the MPSC-02-24-02-7.70-01-L-V provide for a board stacking assembly?
The MPSC-02-24-02-7.70-01-L-V provides a stacking height of 14 mm between the two PCBs it connects, with 28 signal ways arranged in a 4-row S24P4 contact pattern at 2 mm pitch. The 14 mm board-to-board clearance is sufficient to route standard ribbon cables or flex circuits between the stacked boards and allows airflow for passive cooling of components mounted on the inner PCB surfaces in an enclosed chassis design.
Why choose a through-hole board stacking socket like MPSC-02-24-02-7.70-01-L-V over an SMT stacking connector for industrial designs?
Through-hole mounting of the MPSC-02-24-02-7.70-01-L-V provides solder joints that pass entirely through the PCB, giving pull-out force typically 5 to 10 times higher than comparable SMT solder pads. This mechanical advantage is critical in industrial enclosures subject to shock of 50 g half-sine pulse or sustained vibration of 5 g to 20 g, where SMT-only stacking connectors may develop solder joint fatigue. The through-hole design also simplifies hand-soldering for low-volume prototypes when automated SMT reflow is not available.
What is the footprint size of MPSC-02-24-02-7.70-01-L-V and how should PCB designers plan for it?
The MPSC-02-24-02-7.70-01-L-V has a body length of 1.631 inches (41.4 mm), body breadth of 0.400 inches (10.2 mm), and body depth of 0.396 inches (10.1 mm). Designers should place through-hole pads on a 2 mm grid in a 4-row arrangement spanning approximately 42 mm x 10 mm and reserve a 3 mm keep-out zone around the connector body for soldering iron access and mechanical clearance. The 14 mm stacking height must be verified against component heights on both boards to prevent mechanical interference within the inter-board gap.
What is the lead time for MPSC-02-24-02-7.70-01-L-V and how does it compare to longer-lead Samtec stacking products?
The MPSC-02-24-02-7.70-01-L-V has a factory lead time of only 3 weeks, which is significantly shorter than many Samtec specialty connectors that run 10 to 15 weeks. This rapid availability makes the MPSC series attractive for engineering prototype builds, pilot production runs, and urgent field replacement orders. For production volumes requiring consistent supply, the short 3-week lead time also reduces the safety stock needed in a just-in-time manufacturing environment compared to alternative 2 mm pitch stacking sockets with 8-week or longer lead times.
