What are the key features of SFM-146-L2-FM-D-A-K?
- 92-position dual-row layout at 0.050" (1.27 mm) pitch provides one of the highest pin counts in the SFM family for maximum I/O density
- High-reliability SMT termination tolerates thermal cycling from -55°C to +125°C and repeated vibration without contact degradation
- Low-profile surface-mount construction enables slim mezzanine and daughter-card stacking with minimal stack height
- Samtec SFM series compatibility guarantees a precisely matched mating header for a verified 92-pin interconnect system
What is SFM-146-L2-FM-D-A-K used for?
The SFM-146-L2-FM-D-A-K is used in demanding high-pin-count mezzanine and board-to-board applications such as FPGA I/O expansion boards, high-speed networking line cards, and modular embedded computing platforms requiring up to 92 signal connections. Its 0.050-inch pitch supports parallel buses, differential signal pairs, and combined power and signal routing in a compact SMT footprint. The reflow-compatible termination integrates seamlessly into automated pick-and-place assembly processes for high-volume production.

Frequently Asked Questions
How many contacts does SFM-146-L2-FM-D-A-K provide, and how are they arranged?
The SFM-146-L2-FM-D-A-K offers 92 contacts arranged in 2 rows of 46 positions each at a 0.050-inch (1.27 mm) pitch. This dual-row configuration spans approximately 58 mm in length and supports high-density routing of differential pairs such as LVDS, parallel data buses up to 46-bits wide, and mixed signal-plus-power connections in a single SMT connector.
For a mezzanine PCB design, what operating temperature range does SFM-146-L2-FM-D-A-K support?
The SFM-146-L2-FM-D-A-K is rated for an operating temperature range of -55°C to +125°C, covering standard commercial, industrial, and extended temperature profiles. This range makes the connector suitable for industrial automation rack systems, outdoor telecommunications equipment, and defense electronics where ambient temperatures can vary by more than 100°C during operation.
How does the 92-pin SFM-146-L2-FM-D-A-K compare to a lower-pin-count SFM connector when routing a 64-bit parallel bus?
A 92-position connector like the SFM-146-L2-FM-D-A-K provides 46 pins per row, leaving 28 spare contacts beyond the 64 required for a full 64-bit parallel bus plus byte-enable signals. Those extra pins can carry power, ground, or additional control signals without needing a second connector, saving board area and reducing impedance discontinuities compared to using two smaller SFM connectors in series.
Which Samtec mating header is recommended to complete a board-to-board stack with SFM-146-L2-FM-D-A-K?
The SFM-146-L2-FM-D-A-K is designed to mate with the corresponding Samtec TSM-146 or SFM-146 series 92-position header sharing the same 0.050-inch dual-row pitch. The matched pair delivers a contact resistance typically below 20 milliohms per pin and supports a mating cycle life exceeding 100 insertions, ensuring reliable signal integrity for high-frequency board-to-board interfaces.
