What are the key features of TSM-110-03-H-DH-A-P-TR?
- 20-position, 0.100 inch (2.54 mm) pitch SMT terminal strip with dual-height (DH) contact option for flexible stacking configurations
- Gold-plated contact surfaces deliver low contact resistance and corrosion resistance across extended mating cycles in industrial environments
- Horizontal SMT orientation and compact footprint reduce overall board-to-board stack height for low-profile assembly designs
- Tape-and-reel packaging supports automated SMT pick-and-place lines for cost-efficient high-volume manufacturing
What is TSM-110-03-H-DH-A-P-TR used for?
The TSM-110-03-H-DH-A-P-TR is used as a board-to-board or board-to-module pin header where 20 signals must be connected on a 0.100 inch SMT footprint with a dual-height contact geometry. Industrial control panels, embedded processing modules, and test-and-measurement interface boards use this connector to mate with corresponding SMH-series sockets or standard 0.100 inch receptacles, enabling modular hardware architectures with consistent electrical performance. Tape-and-reel delivery makes it practical for automated assembly in medium- to high-volume production of IoT devices, programmable logic controllers, and sensor interface cards.

Frequently Asked Questions
What does the DH suffix in TSM-110-03-H-DH-A-P-TR signify and how does it affect mating options?
The DH suffix designates a dual-height contact, meaning the pin protrudes at two different heights above the PCB surface, typically a shorter mating length of approximately 3 mm and a taller one of 6 mm or more. This allows the same header to mate with both standard-height and elevated socket strips, giving system designers flexibility to select the board-to-board stack height that fits their enclosure without changing the PCB footprint.
How many contacts does TSM-110-03-H-DH-A-P-TR provide and on what pitch, and how does that suit a 20-signal interface?
The connector provides 20 contacts on a 0.100 inch (2.54 mm) pitch in a single-row SMT strip approximately 50 mm long. A 20-pin interface at 2.54 mm pitch is well matched to buses carrying SPI, I2C, UART, GPIO, and a few power and ground pins simultaneously, covering the majority of embedded peripheral expansion needs without requiring a larger or finer-pitch connector.
When is the TSM-110-03-H-DH-A-P-TR a more appropriate choice than a through-hole pin header for surface-mount PCBs?
An SMT terminal strip avoids 20 drilled through-holes, lowering PCB fabrication cost and freeing inner-layer routing channels in multilayer designs. The surface-mount solder termination also withstands SMT reflow profiles up to 260 °C, matching standard lead-free assembly, whereas through-hole pins require selective solder or hand soldering if the board uses a no-clean reflow process. For production volumes above 200 units, the automated placement enabled by TR packaging further reduces total assembly cost.
What are compatible mating connectors for TSM-110-03-H-DH-A-P-TR in a 20-pin board-to-board interface?
The TSM-110-03-H-DH-A-P-TR mates with Samtec SMH-110 series single-row SMT sockets and with standard 0.100 inch single-row receptacles from other suppliers on a 2.54 mm pitch. It also accepts standard 20-pin IDC ribbon-cable plugs and 20-position machine-pin female headers, providing sourcing flexibility across multiple connector families and enabling both direct board-to-board stacking and cable-connected configurations in the same 20-pin footprint.
