What are the key features of SFM-148-02-STL-D-LC?
- 96-position dual-row layout at 1.27 mm (0.050 inch) pitch for ultra-high-density SMT socket interconnects in compact assemblies
- Low-contact (LC) tail height reduces stacking clearance, ideal for slim mezzanine and module-on-module designs
- High-reliability contact construction suited for aerospace, defense, and industrial plug-in modules with extended mating cycles
What is SFM-148-02-STL-D-LC used for?
The SFM-148-02-STL-D-LC is used in high pin-count mezzanine socket applications for FPGAs, processor modules, and memory daughter cards where 0.050 inch pitch maximizes connection density within a small PCB footprint. Its 96-position dual-row configuration supports wide parallel buses and multi-lane high-speed interfaces in aerospace avionics, defense electronics, and advanced test instrumentation. The low-profile LC tail and SMT design enable thin multi-board stack assemblies meeting strict height constraints.

Frequently Asked Questions
How many positions does the SFM-148-02-STL-D-LC provide and at what pitch spacing?
The SFM-148-02-STL-D-LC offers 96 contact positions arranged in a dual-row configuration at 1.27 mm (0.050 inch) pitch, with 48 contacts per row. This high-density layout is suited for wide parallel data bus interfaces and multi-signal mezzanine connections in compact surface-mount PCB assemblies.
What advantage does the LC tail height of the SFM-148-02-STL-D-LC provide for stacked board designs?
The LC (low-contact) tail height designation on the SFM-148-02-STL-D-LC minimizes the PCB-to-PCB standoff distance when mated with a corresponding header. For mezzanine module designs where total stack height must remain under a few millimeters, the LC variant at 1.27 mm pitch reduces clearance compared to standard tail height variants, enabling slimmer multi-board assemblies.
How does the SFM-148-02-STL-D-LC compare to 2.54 mm pitch alternatives for 96-position interfaces?
At 1.27 mm (0.050 inch) pitch, the SFM-148-02-STL-D-LC occupies roughly half the board length of an equivalent 2.54 mm pitch dual-row connector for 96 positions. This halved footprint is critical in space-constrained PCB layouts for FPGA expansion boards, processor modules, and avionics systems where dense connector placement is essential.
In which certification or qualification environments are SAMTEC SFM series sockets commonly specified?
SAMTEC SFM high-reliability socket strips are frequently specified for MIL-STD, aerospace, and industrial applications requiring operation from -55°C to +125°C with gold-plated contacts that maintain consistent contact resistance over hundreds of mating cycles. The 96-position SFM-148-02-STL-D-LC meets the demanding environmental and mechanical requirements of defense avionics and scientific instrumentation.
