SFM-144-T2-F-D-LC SAMTEC Connector (Other) In Stock
SAMTEC SFM-144-T2-F-D-LC is an 88-position dual-row high-reliability socket strip on a fine 0.050 inch (1.27 mm) pitch, designed for surface mount board-to-board and mezzanine card applications requiring high contact density. Gold-plated contacts rated at 1 A each deliver consistent signal and low-power distribution across 44 positions per row in a compact SMT footprint. Available from authorized global distributors with worldwide shipping for engineering and production quantities.

What are the key features of SFM-144-T2-F-D-LC?
- 88 positions in dual-row 0.050" (1.27 mm) pitch delivering high-density surface mount board-to-board interconnection
- High-reliability socket strip with gold-plated contacts rated for thousands of mating cycles with stable contact resistance
- 1 A per contact rating enables simultaneous signal and low-power bus distribution across all 88 positions
- Compact surface mount footprint compatible with standard lead-free reflow assembly profiles up to 260 °C
What is SFM-144-T2-F-D-LC used for?
The SFM-144-T2-F-D-LC targets high-density mezzanine card, FPGA daughter-board, and multi-module interconnect designs in defense electronics, advanced computing, and high-end test-and-measurement equipment where 88 contacts must be routed in a minimum PCB footprint. Its 0.050 inch pitch provides twice the contact density of 0.100 inch alternatives, enabling compact board stack-ups that cannot accommodate wider connectors. The high-reliability socket construction ensures stable electrical performance across extended temperature ranges and repeated mate/unmate cycles common in field-serviceable defense and industrial systems.

Frequently Asked Questions
How does the 0.050 inch pitch of the SFM-144-T2-F-D-LC compare to a standard 0.100 inch pitch socket strip with the same contact count?
At 0.050 inch (1.27 mm) pitch, the SFM-144-T2-F-D-LC occupies roughly half the board length of a 0.100 inch pitch connector carrying the same 88 contacts. For a dual-row layout with 44 contacts per row, the 0.050 inch pitch body spans approximately 54 mm, whereas a 0.100 inch pitch equivalent would require about 108 mm — a saving of 54 mm of critical board edge in compact mezzanine or FPGA daughter-card designs.
What current is each contact in the SFM-144-T2-F-D-LC rated for, and can contacts be ganged for higher-current power rails?
Each of the 88 contacts is rated at 1 A. To supply higher-current rails, contacts can be ganged in parallel — for instance, 5 contacts in parallel provide 5 A for a 5 V supply rail, while the remaining 83 contacts carry independent signal lines. This ganging approach is standard practice in SAMTEC SFM series designs and is documented in their application notes for mixed signal-and-power bus configurations.
What distinguishes the SFM-144-T2-F-D-LC from lower-cost socket strips in high-reliability defense or avionics programs?
The SFM-144-T2-F-D-LC is built to SAMTEC's high-reliability socket strip standard with gold-plated contacts that maintain contact resistance below 20 milliohms over thousands of mating cycles and across an operating temperature range of -55 °C to +125 °C. Lower-cost commercial socket strips typically specify a narrower temperature range of 0 °C to +85 °C and fewer guaranteed mating cycles, which is insufficient for defense avionics and industrial programs requiring 10,000-hour MTBF targets.
Which mating plug header mates with the SFM-144-T2-F-D-LC, and what mounting orientations are supported?
The SFM-144-T2-F-D-LC belongs to SAMTEC's SFM series and mates with corresponding TSM or SFM-compatible 0.050 inch pitch pin header plugs on the same 1.27 mm grid. The dual-row socket supports vertical (perpendicular board-to-board) mating, which is the standard orientation for 88-position mezzanine card interconnects, allowing board stack heights to be adjusted by selecting mating headers of different tail lengths ranging from 2 mm to 12 mm.
