What are the key features of SFM-119-T2-SM-D-LC?
- 38-position dual-row SMT socket strip with 1.27 mm (0.050") pitch for fine-pitch high-density signal routing
- Low-clearance (LC) design enabling minimal board-to-board separation in compact stacked PCB assemblies
- Silver-mated (SM) contact finish providing reliable low-resistance connections across all 38 positions
- High-reliability construction rated to 105°C for demanding aerospace, defense, and industrial applications
What is SFM-119-T2-SM-D-LC used for?
The SFM-119-T2-SM-D-LC is designed for high-reliability aerospace, defense, and industrial electronics applications where 38-position dual-row fine-pitch (1.27 mm / 0.050 inch) SMT socket connectors with low installed height are needed. Its silver-mated contacts provide consistent electrical performance for signal and low-power interfaces in mezzanine and daughter-card assemblies. The low-clearance profile supports tightly stacked multi-board systems in constrained enclosures.

Frequently Asked Questions
What does the SM contact finish in SFM-119-T2-SM-D-LC mean for connector performance?
The SM designation in SFM-119-T2-SM-D-LC indicates silver-mated contact plating, which offers good electrical conductivity and lower cost compared to gold while still providing reliable contact performance across all 38 positions. Silver contacts are appropriate for signal interfaces where contact resistance and corrosion performance under the 105°C operating temperature rating are adequate, and where design budgets favor silver over gold plating in high-reliability SMT connectors.
How does the 38-position count of SFM-119-T2-SM-D-LC compare to adjacent SFM series variants for sizing decisions?
The SFM-119-T2-SM-D-LC provides 38 total positions (19 signal pairs) at 1.27 mm pitch. Adjacent variants such as the SFM-120 offer 40 positions and the SFM-118 would offer 36 positions in the same pitch series. Engineers select among these based on the exact interface signal count, as each 2-position increment in the SFM series corresponds to 1 additional signal pair and a 2.54 mm incremental increase in connector body length.
Why is SFM-119-T2-SM-D-LC a strong fit for compact mezzanine boards with limited vertical clearance?
The LC (low-clearance) suffix on the SFM-119-T2-SM-D-LC specifies a reduced installed height, which directly limits the board-to-board gap in stacked mezzanine assemblies. For avionics line-replaceable units, ruggedized military electronics, and compact embedded systems, minimizing stack height is a key mechanical requirement. The connector's 1.27 mm (0.050 inch) pitch and 38-position dual-row SMT layout provide 19 signal pairs within this height-optimized form factor.
What current and temperature ratings apply to SFM-119-T2-SM-D-LC in a continuous-duty application?
Each of the 38 positions in the SFM-119-T2-SM-D-LC supports 1.0 A continuous current, with an operating temperature range up to 105°C. These ratings cover typical logic-level signal and low-power supply lines found in aerospace and industrial PCB designs. Silver-mated contacts maintain consistent contact resistance within these thermal and current limits, supporting reliable operation across the connector's expected service life in demanding high-reliability environments.
