What are the key features of TSM-143-04-STL-DV-P-TR?
- 86-position dual-row SMT strip on 0.100 inch (2.54 mm) pitch supporting wide parallel-bus board-to-board connections
- STL (stacking tall) profile provides increased mated stack height of 4 mm or more for component clearance between stacked boards
- Tape-and-reel packaging enables automated pick-and-place assembly in medium-to-high volume PCB production runs
What is TSM-143-04-STL-DV-P-TR used for?
TSM-143-04-STL-DV-P-TR is suited for stacked PCB assemblies in industrial controllers, embedded computing modules, and power management boards requiring 86-pin signal connectivity with elevated clearance between boards. The STL profile ensures that tall components such as capacitors or inductors on the lower board fit within the mated stack. Its 0.100 inch pitch is backward-compatible with standard through-hole and SMT 2.54 mm grid layouts.

Frequently Asked Questions
What does the STL suffix indicate about TSM-143-04-STL-DV-P-TR's stack height compared to a standard TSM terminal strip?
The STL suffix denotes a stacking-tall profile on TSM-143-04-STL-DV-P-TR, increasing the mated height above the standard 8.5 mm to accommodate components taller than 4 mm on the lower board. This extra clearance is essential when capacitors, inductors, or connectors on the bottom PCB would otherwise be crushed or shorted against the upper mating board in a stacked assembly.
How does the 86-position dual-row layout of TSM-143-04-STL-DV-P-TR handle mixed power and signal assignments?
With 86 total positions arranged as 2 rows of 43 pins at 0.100 inch (2.54 mm) pitch, TSM-143-04-STL-DV-P-TR allows designers to dedicate groups of adjacent pins to power rails—typically 2 A per pin continuous—while using remaining pins for data, control, and ground signals. This flexibility makes the strip practical for embedded computing carrier boards where power and I/O must share a single 86-pin interface.
For a compact industrial controller with stacked PCBs, when is TSM-143-04-STL-DV-P-TR a better fit than a flat-profile 0.050 inch pitch alternative?
TSM-143-04-STL-DV-P-TR is preferred when the stack design targets standard 0.100 inch grid PCB routing, when individual pin current exceeds 1 A per channel—common in mixed power-signal backplanes—or when the board-to-board gap must exceed 8 mm to clear tall passive components. The 2.54 mm pitch also reduces insertion-force sensitivity compared to 0.050 inch pitch connectors in manual prototyping or field-service replacement scenarios.
