Key Features
- 88-position dual-row socket strip on 1.27 mm (0.050 inch) pitch delivers high-density mating in a compact SMT footprint
- High-reliability construction with gold-plated contacts ensures low contact resistance and long mating cycle life exceeding 500 cycles
- Tape-and-reel (-TR) packaging supports automated SMT pick-and-place assembly for high-volume PCB production
Applications
The SFM-144-L2-H-D-A-P-TR is designed for high-density board-to-board mating in space-constrained applications such as embedded computing modules, RF and microwave test fixtures, and FPGA daughter card sockets. Its 1.27 mm pitch and SMT footprint allow tight component spacing while the high-reliability contacts support frequent mating and demating cycles common in modular system architectures.

Frequently Asked Questions
What pitch and position count does the SFM-144-L2-H-D-A-P-TR offer for high-density board interconnect?
The SFM-144-L2-H-D-A-P-TR provides 88 positions on a 1.27 mm (0.050 inch) pitch in a dual-row surface mount configuration. The 0.050 inch pitch is half the spacing of standard 2.54 mm connectors, making it ideal for applications requiring maximum I/O density in a minimal PCB footprint such as compact embedded modules.
How many mating cycles can the SFM-144-L2-H-D-A-P-TR withstand in a modular system?
SAMTEC SFM-series high-reliability socket strips are rated for at least 500 mating cycles with gold-plated contacts, ensuring long service life in module-swapping environments. This durability is critical in test and measurement equipment or field-replaceable daughtercard architectures where the connector is engaged and disengaged frequently.
Which daughter card or module designs are best matched to the SFM-144-L2-H-D-A-P-TR?
FPGA mezzanine cards, embedded processor daughter boards, and RF shielded modules operating on standard 3.3 V or 1.8 V I/O rails benefit from the 88-position 1.27 mm pitch dual-row socket. The SMT attachment requires no through-holes, saving PCB layer stackup space and reducing fabrication cost while still supporting high-speed differential signal pairs at speeds exceeding 10 Gbps.
