What are the key features of SFM-128-L2-F-D-A-P-TR?
- 56-position dual-row fine-pitch 1.27 mm (0.050 inch) socket strip enables high-density SMT board-to-board interconnect in space-constrained designs
- High-reliability construction with gold-plated contacts ensures low contact resistance and long mating cycle life exceeding 30 insertion cycles
- Tape and reel (TR) packaging supports automated pick-and-place assembly for high-volume PCB production
What is SFM-128-L2-F-D-A-P-TR used for?
The SFM-128-L2-F-D-A-P-TR is used in high-density board-to-board and mezzanine interconnect applications where 1.27 mm pitch is required, such as embedded computing modules, RF front-end boards, and instrumentation systems. Its 56-position dual-row layout supports wide parallel data buses and multi-signal interfaces between stacked PCBs. The SMT footprint and tape-and-reel format make it suitable for automated assembly in high-volume production.

Frequently Asked Questions
What is the pitch and pin count of the SFM-128-L2-F-D-A-P-TR, and how many positions are in each row?
The SFM-128-L2-F-D-A-P-TR has a 1.27 mm (0.050 inch) pitch with 56 total positions arranged in a dual-row configuration, giving 28 pins per row. This fine-pitch layout is optimized for compact board-to-board mating where space is limited.
In which embedded computing or RF module designs would SFM-128-L2-F-D-A-P-TR be a preferred choice?
This connector is well suited for COM Express, PC/104, and custom mezzanine modules where a 1.27 mm pitch dual-row socket with 56 positions must fit within a 3.5-inch or smaller PCB footprint. It supports signal speeds up to 10 Gbps per lane in high-speed digital designs and is used in FPGAs, DSP boards, and SDR front-end modules.
What is the mating connector family for SFM-128-L2-F-D-A-P-TR and how does it compare to standard 2.54 mm pitch alternatives?
The SFM series mates with SAMTEC's SSM header series at 1.27 mm pitch. Compared to standard 2.54 mm pitch connectors, the SFM-128 at 1.27 mm pitch reduces connector footprint by approximately 75%, enabling 56 positions in roughly the same board area that a 2.54 mm 28-position dual-row header would occupy.
