Key Features
- 96-position dual-row configuration at 0.050" (1.27 mm) pitch delivers very high contact density for compact board-to-board mezzanine designs
- STL solder tail termination style optimized for surface mount reflow assembly with consistent solder joint formation across all 96 contacts
- High-reliability socket strip construction with gold-plated contacts ensures low contact resistance and extended mating cycle life
- Non-tape-and-reel tray packaging (no TR suffix) suited for engineering prototype builds and low-to-medium volume production runs
Applications
The SFM-148-T2-STL-D-A-K is used in high-density FPGA mezzanine modules, server blade interconnects, and defense electronics where 96-pin dual-row 0.050" pitch SMT socket strips are required for reliable board-to-board signal routing. Its high-reliability rating and gold-plated contacts make it an excellent choice for telecommunications switching equipment, industrial computing platforms, and instrumentation that demands stable interconnect performance over thousands of mating cycles.

Frequently Asked Questions
What is the pin count, pitch, and row configuration of the SFM-148-T2-STL-D-A-K, and how does it affect layout density?
The SFM-148-T2-STL-D-A-K has 96 positions in a dual-row arrangement with 0.050" (1.27 mm) pitch, placing 48 contacts per row in a surface mount footprint roughly half the size of equivalent 2.54 mm pitch connectors, enabling significantly higher interconnect density on multilayer PCBs in space-constrained computing and communications designs.
Which SAMTEC mating headers are compatible with the SFM-148-T2-STL-D-A-K for high-density board stacking?
The SFM-148-T2-STL-D-A-K is designed to mate with SAMTEC TSM or SFM series 96-position dual-row male headers sharing the 0.050" (1.27 mm) pitch, enabling reliable board-to-board stacking for FPGA mezzanine cards, daughter card modules, and other high-density interconnect architectures where 96 simultaneous signal channels are required.
When should a designer select the SFM-148-T2-STL-D-A-K over a lower pin-count or wider-pitch socket for a mezzanine interface?
A designer should select the SFM-148-T2-STL-D-A-K when the interface must route at least 96 signals across a compact footprint at 0.050" (1.27 mm) pitch, as wider 0.100" pitch alternatives require approximately twice the board area for the same pin count, and lower pin-count connectors would require multiple parallel connectors to match the 96-channel capacity of this single high-reliability socket strip.
