What are the key features of SFM-149-L2-LM-D-A-P-TR?
- 98-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch for maximum-density board-to-board mezzanine connections
- High-reliability low-crosstalk contacts rated for consistent performance across extended mating cycles in demanding environments
- Low-profile surface-mount termination minimizes PCB stack height while accommodating 98 signal and power connections in a compact footprint
- Tape-and-reel (TR) packaging provides compatibility with automated pick-and-place assembly on standard SMT production lines
What is SFM-149-L2-LM-D-A-P-TR used for?
The SFM-149-L2-LM-D-A-P-TR is used in high-bandwidth FPGA mezzanine modules, server processor daughter cards, and multi-channel data acquisition boards where routing more than 96 signals between stacked PCBs is required at 0.050" pitch. Its 98-position count accommodates wide parallel data buses, multiple differential signal pairs, and power rails simultaneously in a single SMT socket, making it ideal for telecom switching fabrics, military electronics, and high-performance embedded computing platforms. The tape-and-reel format enables efficient volume production of dense interconnect assemblies in networking, defense, and industrial control systems.

Frequently Asked Questions
What is the maximum connector density the SFM-149-L2-LM-D-A-P-TR achieves, and how does it compare to the 94-position SFM-147?
The SFM-149-L2-LM-D-A-P-TR provides 98 positions at 0.050" (1.27 mm) dual-row pitch, offering 4 more contact positions than the 94-position SFM-147-T2-FM-D-LC. This higher density allows routing of additional signal lines — such as an extra 4-bit bus segment or 2 differential pairs — within essentially the same board footprint, benefiting FPGA mezzanine designs where every available pin is assigned to high-speed data paths.
Which high-performance computing board architectures benefit most from the SFM-149-L2-LM-D-A-P-TR's 98-position count?
Server processor boards, FPGA HPC mezzanine cards, and multi-channel signal processing platforms benefit most from the SFM-149-L2-LM-D-A-P-TR's 98 contacts. These architectures must route 64-bit or 72-bit wide memory buses alongside control signals, multiple 3.3 V and 1.8 V power rails, and differential high-speed pairs — a task that requires 90 or more pins at 1.27 mm pitch to avoid using multiple separate connectors.
What current capacity does the SFM-149-L2-LM-D-A-P-TR provide for power distribution alongside signal lines?
Each contact in the SFM-149-L2-LM-D-A-P-TR is rated at approximately 1 A, consistent with the SAMTEC SFM series for 0.050" pitch connectors. With 98 positions available, multiple pins can be paralleled to carry higher aggregate supply currents — for example, assigning 10 pins to a 3.3 V rail delivers up to 10 A of shared current capacity alongside the remaining 88 signal lines.
How does the tape-and-reel supply format of the SFM-149-L2-LM-D-A-P-TR support cost-effective volume production?
Tape-and-reel packaging eliminates manual loading interruptions and enables continuous automated pick-and-place placement at high throughput for the 98-position SMT socket. This reduces per-board assembly labor cost and placement error rates compared to loose-piece or cut-tape supply, which is particularly impactful for production runs of hundreds or thousands of FPGA carrier boards, telecom blades, or industrial control modules where the SFM-149 appears on every unit.
