What are the key features of SFM-140-02-FM-D-LC?
- 80 positions (40 per row) at 0.050 inch pitch enabling very high signal density in a compact SMT footprint
- Flush-mount (FM) low-profile design minimizing stack height for tightly spaced board-to-board assemblies
- Lead-free compatible (LC) gold-plated contacts ensuring RoHS compliance and reliable low-resistance mating
- Dual-row surface-mount construction for stable solder joint formation and mechanical robustness in PCB assemblies
What is SFM-140-02-FM-D-LC used for?
The SFM-140-02-FM-D-LC is deployed in FPGA mezzanine card (FMC) applications, high-density data acquisition modules, and communication backplane daughtercards requiring 80 contacts at a fine 1.27 mm pitch with a low stack height. Its flush-mount surface-mount profile is especially valuable in space-constrained multi-board computing and RF systems where minimizing the connector's above-board protrusion is essential.

Frequently Asked Questions
How many contacts does SFM-140-02-FM-D-LC provide per row, and what total pin count does the dual-row design deliver?
The SFM-140-02-FM-D-LC provides 40 contacts per row in a dual-row configuration for a total of 80 pins. Distributed at 0.050 inch (1.27 mm) pitch, the 80-pin layout spans approximately 50.8 mm per row, enabling routing of 80 parallel signal or power lines in a single connector footprint for data acquisition, FPGA expansion, and high-density instrumentation boards.
What does the FM designation mean in SFM-140-02-FM-D-LC, and how does it benefit low-profile designs?
FM stands for flush mount, meaning the connector body sits close to the PCB surface with minimal above-board protrusion, typically 1 mm to 3 mm in installed height. This is critical in multi-board assemblies where the board-to-board gap must be minimized to less than 5 mm, allowing designers to stack compute modules, sensor boards, or RF daughtercards in tight enclosures without clearance violations.
For a PCB designer routing 80 signals on an FPGA daughterboard, what footprint area does SFM-140-02-FM-D-LC occupy?
The SFM-140-02-FM-D-LC with 80 pins at 0.050 inch (1.27 mm) pitch in dual rows occupies a pad array of approximately 51 mm x 2.54 mm for the contact field, plus connector body margins. This dense 2-row layout routes 80 independent signals in a narrow 51 mm long strip, making it one of the most area-efficient through-options at this pin count for FPGA mezzanine and test-and-measurement expansion connectors.
Is SFM-140-02-FM-D-LC compliant with RoHS and lead-free reflow processes?
Yes, the LC suffix denotes a lead-free compatible finish, and the connector is RoHS compliant. Its contact plating withstands lead-free reflow soldering profiles up to 260 °C peak temperature per IPC/JEDEC J-STD-020, and the mating contacts use gold plating over nickel providing contact resistance below 20 milliohms for reliable signal transmission across 80 positions in SMT production environments.
