What are the key features of SFM-147-L2-LM-D-A-K-TR?
- 94 contacts in a dual-row configuration at 0.050" (1.27 mm) pitch for very high-density mezzanine-level interconnects
- Gold-plated (K option) contacts maintaining low contact resistance over hundreds of mating cycles in demanding environments
- Low-profile mezzanine (LM) design minimizing stacking height for compact multi-board assemblies in space-constrained enclosures
What is SFM-147-L2-LM-D-A-K-TR used for?
The SFM-147-L2-LM-D-A-K-TR is targeted at high-density mezzanine stacking in FPGA evaluation boards, network switch line cards, and high-performance computing modules requiring 94-pin connectivity at 1.27 mm pitch. Its low-profile construction reduces the board-to-board stacking height, making it suitable for compact server blades, RF front-end modules, and avionics mission computers where vertical space is tightly constrained.

Frequently Asked Questions
What total pin count and pitch does the SFM-147-L2-LM-D-A-K-TR offer for mezzanine stacking?
The SFM-147-L2-LM-D-A-K-TR provides 94 contacts in a dual-row layout at 0.050" (1.27 mm) pitch, one of the highest pin counts available in the SAMTEC SFM series at this spacing. This density supports simultaneous routing of high-speed differential pairs, single-ended signals, and power rails across a single mezzanine connector footprint.
How does the low-profile mezzanine (LM) design of the SFM-147-L2-LM-D-A-K-TR benefit multi-board sandwich assemblies?
The low-profile mezzanine design reduces the board-to-board stacking height compared to standard SFM socket strips, enabling tighter vertical integration in chassis with limited Z-clearance such as 1U rack servers or flat panel controllers. For a 94-position interconnect at 1.27 mm pitch, even a 0.5 mm reduction in stack height can make the difference between fitting or exceeding a mechanical envelope.
When should a designer choose SFM-147-L2-LM-D-A-K-TR over a lower-count SFM socket to consolidate interconnects?
At 94 contacts, the SFM-147-L2-LM-D-A-K-TR replaces multiple smaller SFM connectors when a design needs to route 80–94 signals at 1.27 mm pitch in a single mating event, reducing the assembly step count and the risk of partial-connection errors. Consolidating into one 94-position socket also simplifies the PCB keepout zone compared to placing two 48-position SFM-124 sockets side by side.
