What are the key features of SFM-147-02-LM-D-LC?
- 94-position dual-row layout at 1.27 mm (0.050 inch) pitch enabling very high-density SMT signal interconnect on compact boards
- LC low-clearance contact style minimizing the vertical stack height between mated PCBs for tight assembly envelopes
- High-reliability gold-plated contacts providing stable contact resistance across many mating cycles in demanding environments
- LM (lead modification) contact feature accommodating slight positional tolerance for easier board alignment during mating
- Tray or tube packaging (non-TR) suited for prototype, engineering sample, or low-to-medium volume through-hole assembly
What is SFM-147-02-LM-D-LC used for?
The SFM-147-02-LM-D-LC serves high-density board-to-board and mezzanine card interconnect applications in FPGA development platforms, embedded computing modules, and aerospace avionics where 94 signals must be carried at a 1.27 mm pitch with minimal connector height. Its LC low-clearance contact style supports tight stack-height board assemblies, and the LM lead modification eases alignment in automated or manual mating. The non-TR packaging suits prototyping, qualification builds, and low-volume production runs.

Frequently Asked Questions
What does the LM suffix mean in the SFM-147-02-LM-D-LC part number, and how does it affect board mating?
The LM suffix denotes a lead-modification on the contact tails of the SFM-147-02-LM-D-LC, which adds a slight formed bend or offset to the SMT pad footprint. This modification allows a small tolerance in X-Y alignment when two PCBs are mated at 1.27 mm pitch across all 94 positions, reducing the risk of misalignment-induced solder opens or connector damage during assembly and mating in production environments.
How many contact positions does the SFM-147-02-LM-D-LC carry, and how is the dual-row arrangement laid out?
The SFM-147-02-LM-D-LC provides 94 contact positions in a dual-row format with 47 contacts per row at 1.27 mm (0.050 inch) pitch. Compared to a single-row 94-pin strip at the same pitch, this dual-row design requires only about half the PCB board edge, allowing 94-signal interconnect in a compact footprint suited to FPGA mezzanine boards, industrial embedded computers, and other space-constrained PCB assemblies.
What is the LC contact style in the SFM-147-02-LM-D-LC, and which designs benefit from it?
LC stands for low-clearance, meaning the SFM-147-02-LM-D-LC's contacts are designed to minimize the vertical height above the PCB after mating. This is critical in board-stack assemblies where the gap between two mated boards must be as small as possible, such as in avionic sub-module stacks, miniaturized embedded computing boards, or wearable devices where every fraction of a millimetre in z-height impacts the overall product envelope.
Is the SFM-147-02-LM-D-LC available for automated SMT assembly, and how does the non-TR packaging affect procurement?
The SFM-147-02-LM-D-LC is a surface-mount device designed for SMT reflow assembly but is supplied in tray or tube format rather than tape-and-reel (no TR suffix). This non-TR packaging is best suited for prototype builds, engineering qualification runs, or low-to-medium volume production where hand-placement or semi-automated assembly is acceptable. For high-volume automated pick-and-place production across all 94 positions, engineers should evaluate the TR-suffixed variant of the SFM-147 series.
