What are the key features of FX8-140S-SV?
- 140 positions in a 1.913-inch body enable high pin-count board stacking without increasing PCB footprint across multiple signal and power rails
- Low-profile 0.089-inch stack height minimises z-axis clearance between stacked boards in slim embedded and IoT module assemblies
- PEG mounting option locks the connector to the PCB before soldering, improving alignment accuracy in automated SMT placement
- Pb-free RoHS-compliant terminations support lead-free wave and reflow soldering processes in environmentally regulated markets
What is FX8-140S-SV used for?
The FX8-140S-SV is used in board-stacking configurations for compact embedded computing modules, SOM-to-carrier board interfaces, and high-density wireless communication boards where 140 signals must transit between PCB layers in the minimum possible z-axis stack height. Its low-profile receptacle design also suits industrial HMI displays and portable medical devices where stacked PCB assemblies must fit within enclosures constrained to under 10 mm total board separation.

Frequently Asked Questions
How many positions does the FX8-140S-SV provide, and what signal density does that enable for a dual-board SOM design?
The FX8-140S-SV provides 140 positions across a 1.913-inch body, supporting simultaneous routing of high-speed data lanes, multiple power rails, and control signals between a system-on-module and its carrier PCB without requiring additional connectors. At a standard 0.5 mm pitch, 140 pins can accommodate interfaces such as USB 3.0, PCIe ×4, MIPI CSI-2, I²C, SPI, and multiple GPIO banks in a single compact mated pair.
What is the stacked board separation achieved with the FX8-140S-SV, and how does that constrain enclosure height?
The FX8-140S-SV has a body depth of 0.089 inches (approximately 2.26 mm), which defines the minimum board-to-board separation when mated with its complementary plug. Enclosure designers must add the PCB thickness—typically 1.6 mm each—to calculate the total internal height consumed by the dual-board assembly, which is typically under 7 mm, enabling slim embedded computing products with enclosure heights below 15 mm.
What does the PEG mounting feature on the FX8-140S-SV add during PCB assembly, and why is it beneficial for 140-pin connectors?
The PEG mounting tabs press into PCB holes to mechanically lock the FX8-140S-SV in position before and during reflow soldering. For a 140-pin connector spanning nearly 49 mm, this prevents rotation or shifting on the paste deposit when the board enters the reflow oven, eliminating co-planarity defects across all 140 solder joints that would otherwise require costly X-ray inspection and rework.
What lead time should supply chain teams plan around for the FX8-140S-SV, given its 16-week factory lead time?
The FX8-140S-SV carries a 16-week factory lead time from Hirose, which is longer than many commodity connectors. Programs building SOM carrier boards or embedded computing modules should maintain at least 5 months of projected consumption in pipeline and safety stock, and issue purchase orders at project kick-off rather than at BOM freeze to avoid schedule delays during NPI and volume ramp phases.
