Key Features
- 144-position dual-row surface-mount socket strip on 0.050 inch (1.27 mm) pitch for high-density interconnection
- High-reliability construction rated for consistent signal integrity across hundreds of mating cycles in demanding environments
- Low-profile SMT footprint enables board-to-board stacking in space-constrained modules and embedded computing assemblies
Applications
The SFM-144-T2-LM-D-A is used in high-density board-to-board and mezzanine-card interconnect assemblies found in industrial computing, FPGA development boards, and test-and-measurement equipment requiring 144 reliable signal contacts. Its 0.050 inch pitch makes it well-suited for compact embedded modules, daughter-card expansions, and backplane interconnects where PCB real estate is limited. The surface-mount design supports automated pick-and-place assembly, reducing production costs in volume manufacturing environments.

Frequently Asked Questions
How many positions does the SFM-144-T2-LM-D-A have, and what is its contact pitch?
The SFM-144-T2-LM-D-A is a 144-position dual-row socket strip with a 0.050 inch (1.27 mm) contact pitch. The dual-row layout distributes 72 contacts per row, providing a high-density interconnect solution in a compact SMT footprint suitable for space-constrained PCB designs.
Can the SFM-144-T2-LM-D-A be used in mezzanine or daughter-card applications, and what row configuration does it offer?
Yes, the SFM-144-T2-LM-D-A is designed for mezzanine and daughter-card interconnect applications. Its dual-row arrangement with 144 total pins at 0.050 inch (1.27 mm) pitch allows high signal density per unit area. The surface-mount termination makes it compatible with standard automated reflow assembly processes used in industrial and computing card designs.
What mounting style does SFM-144-T2-LM-D-A use, and how does that affect PCB assembly?
The SFM-144-T2-LM-D-A uses a surface-mount technology (SMT) mounting style, meaning all 144 pins are soldered directly to pads on the PCB surface rather than through holes. SMT assembly enables automated pick-and-place and reflow soldering, which reduces assembly time and supports high-volume manufacturing with controlled co-planarity across all contact positions.
Which SAMTEC connector family is the SFM-144-T2-LM-D-A part of, and what alternatives exist for lower pin counts?
The SFM-144-T2-LM-D-A belongs to SAMTEC's SFM socket strip series for 0.050 inch (1.27 mm) pitch dual-row surface-mount applications. For designs requiring fewer contacts, SAMTEC offers the same SFM series in smaller configurations such as 40, 60, 80, or 100 positions, allowing designers to select the exact pin count without changing the connector family or PCB pitch.
