What are the key features of SFM-124-02-STL-D-LC?
- 48-position dual-row layout at 1.27 mm (0.050 inch) pitch for fine-pitch high-density SMT board-to-board interconnect
- STL contact style supporting solderless or alternative attachment methods for reworkable connector placement
- LC low-clearance contact geometry minimizing vertical stack height in tight board-to-board assembly envelopes
- High-reliability construction with gold-plated contacts ensuring low, stable contact resistance over extended mating cycles
- Non-tape-and-reel packaging suited for prototype builds, qualification samples, and low-to-medium volume production runs
What is SFM-124-02-STL-D-LC used for?
The SFM-124-02-STL-D-LC is used in compact board-to-board interconnect applications such as FPGA mezzanine cards, sensor interface modules, and embedded computing daughter boards where 48 signals must be routed at a 1.27 mm pitch with a low connector profile. Its STL contact and LC low-clearance combination make it suitable for aerospace, defense, and industrial electronics requiring both tight vertical stack heights and reworkable connector attachment. The non-TR packaging suits prototype and qualification production builds.

Frequently Asked Questions
What does the STL contact style mean in the SFM-124-02-STL-D-LC, and how does it differ from a standard SMT contact?
The STL suffix indicates a special tail or lead configuration, often a solderable or pressfit tail variant, that allows alternative attachment compared to standard SMT reflow tails. In the SFM-124-02-STL-D-LC, this enables reworkable connector placement across all 48 positions at 1.27 mm pitch without requiring full reflow, useful in prototype development boards, test fixtures, and designs where the connector must be replaced during system debugging or qualification testing.
How many signals can the SFM-124-02-STL-D-LC carry, and what is the physical layout of its contacts?
The SFM-124-02-STL-D-LC carries 48 signals arranged in 2 rows of 24 contacts each at a 1.27 mm (0.050 inch) pitch. The dual-row configuration reduces the required PCB edge length by approximately 50 percent compared to a single-row 48-pin strip at the same pitch, making it ideal for FPGA mezzanine headers, miniature embedded processor boards, and sensor arrays where board space across the connector footprint is limited.
For which application categories is the SFM-124-02-STL-D-LC specifically suited, given its LC contact style and 1.27 mm pitch?
The SFM-124-02-STL-D-LC, with its LC low-clearance contacts at 1.27 mm pitch, is specifically suited to board-stack assemblies where the air gap between two mated PCBs must be minimized to 2 mm or less. Target applications include avionics sub-module stacks, miniature SoM (System-on-Module) board-to-carrier connectors, and wearable medical devices where the total stacked PCB assembly height is constrained to reduce product thickness while maintaining 48-signal interconnect capacity.
How does the non-TR packaging of the SFM-124-02-STL-D-LC affect ordering and assembly decisions?
The absence of a TR suffix means the SFM-124-02-STL-D-LC is shipped in tray or tube rather than tape-and-reel format. This is well-suited for prototype orders, engineering qualification builds, and small production runs where automated pick-and-place machinery is not required. For high-volume automated SMT assembly across all 48 positions at 1.27 mm pitch, engineers should check whether a tape-and-reel variant of the SFM-124 series is available, as TR format reduces per-unit placement time and handling cost significantly.
