Key Features
- 48-position dual-row layout at 0.100 inch (2.54 mm) pitch offering 24 pins per row for high-density PCB interconnect in a compact SMT footprint
- Short top-loaded (STL) surface mount termination enabling low-profile board assemblies with reduced component height for space-constrained enclosures
- Tape-and-reel (TR) packaging optimized for automated SMT pick-and-place production, reducing assembly cycle time and placement error rate
Applications
The SAMTEC TSM-124-04-STL-DH-A-K-TR is suitable for high-density board-to-board and module-to-motherboard interconnect applications in industrial control systems, embedded computing, and communication infrastructure equipment. With 48 positions at 0.100 inch pitch in a dual-row SMT configuration, it provides a large number of reliable signal and power connections in a minimal PCB footprint. The short top-loaded SMT termination and tape-and-reel packaging make it well-adapted to automated high-volume manufacturing environments.

Frequently Asked Questions
What distinguishes the short top-loaded (STL) termination of TSM-124-04-STL-DH-A-K-TR from standard top-loaded variants?
The short top-loaded (STL) termination style of TSM-124-04-STL-DH-A-K-TR provides a reduced standoff height compared to standard top-loaded (TL) variants, typically resulting in an overall SMT component height of under 5 mm. This is advantageous for low-profile PCB assemblies where vertical clearance is constrained and 48 signal connections must be routed without increasing board stack height.
For a 48-signal FPGA expansion interface, how does TSM-124-04-STL-DH-A-K-TR compare to using two separate 24-position strips?
Using the 48-position TSM-124-04-STL-DH-A-K-TR in a single dual-row configuration reduces the number of PCB footprints from 2 to 1, simplifies routing by consolidating all 48 signals at 0.100 inch pitch into one contiguous area, and eliminates the mechanical misalignment risk between two separate connectors. A single 48-position dual-row strip also maintains row-to-row center spacing of 0.100 inch, making it easier to match the mating header on the target module.
Which automated assembly requirements does the tape-and-reel packaging of TSM-124-04-STL-DH-A-K-TR support?
The tape-and-reel (TR) format of TSM-124-04-STL-DH-A-K-TR complies with EIA-481 standards and is compatible with standard SMT pick-and-place feeders on assembly lines running volumes of 500 or more boards per shift. The reel format prevents component tangling, maintains orientation for automated placement at the 0.100 inch pitch landing pads, and reduces per-component handling time compared to bulk or tube packaging.
How much board area does the 48-position dual-row 0.100 inch pitch footprint of TSM-124-04-STL-DH-A-K-TR require?
With 24 positions per row at 0.100 inch (2.54 mm) pitch and dual-row spacing of 0.100 inch, the TSM-124-04-STL-DH-A-K-TR footprint spans approximately 2.4 inches (61 mm) in length and 0.1 inch (2.54 mm) in row-to-row width, plus pad clearances. This compact dual-row arrangement provides 48 contacts in roughly half the PCB length of an equivalent single-row 48-position strip.
