Frequently Asked Questions
How many signal pins does the SFM-144-T2-STL-D-LC carry and at what pitch?
The SFM-144-T2-STL-D-LC carries 88 signal contacts in a dual-row arrangement on a 0.050-inch (1.27 mm) pitch. This combination provides substantial signal density in a surface-mount footprint compatible with standard PCB grid patterns used in embedded computing and communications modules.
What does the LC suffix indicate on the SFM-144-T2-STL-D-LC, and how does it affect procurement cost?
The LC suffix designates a low-cost variant of the SFM socket strip series. Engineers select the LC version when the application requires 88 pins at 0.050-inch pitch without the premium associated with high-reliability or special-plating options, reducing unit cost in volume PCB assembly programs.
For a mezzanine board needing 88 signals in surface-mount form, how does SFM-144-T2-STL-D-LC compare to a through-hole alternative?
The SFM-144-T2-STL-D-LC is a surface-mount socket, so it eliminates drilling for 88 pins per connector location and is compatible with standard reflow soldering, reducing assembly cycle time. Through-hole alternatives at the same pitch typically require wave or selective soldering, increasing process complexity on mixed-technology boards.
In which industries is the SFM-144-T2-STL-D-LC commonly designed into production hardware?
The SFM-144-T2-STL-D-LC is commonly used in industrial automation controllers, embedded computing platforms, test and measurement equipment, and telecommunications line cards. Its 88-position, 0.050-inch pitch dual-row format is well suited for daughter-card and module mezzanine stacking where compact PCB layouts and moderate cycle-life mating are required.
