What are the key features of TSM-123-01-S-DH-A-K-TR?
- 46 pins in a single-row 2.54 mm pitch SMT terminal strip with DH tail-down design for board stacking engagement from below
- Standard 0.100 inch pitch compatible with common dual-row and single-row mating socket headers widely used in embedded development
- Tape-and-reel (TR) packaging enabling automated SMT pick-and-place assembly at high production volumes
What is TSM-123-01-S-DH-A-K-TR used for?
The TSM-123-01-S-DH-A-K-TR is deployed in single-row board-to-board interconnects for embedded controller daughter cards, sensor interface modules, and evaluation platforms requiring 46 signal lines at 2.54 mm pitch. Its tail-down DH construction allows a mating connector to engage the board stack from the underside, reducing the required top-clearance height compared to vertical header designs. The SMT body enables co-processing with other surface-mount components in standard reflow soldering operations.

Frequently Asked Questions
How many positions does TSM-123-01-S-DH-A-K-TR have, and what is its row configuration?
The TSM-123-01-S-DH-A-K-TR is a single-row connector with 46 positions at 2.54 mm (0.100 inch) pitch. A single-row 46-pin strip spans approximately 114 mm on the PCB, carrying up to 32 GPIO lines plus power, ground, and control signals for a microcontroller daughter card or expansion shield interconnect.
What does the DH designation mean for TSM-123-01-S-DH-A-K-TR, and how does it affect board stack height?
DH means dual height — the connector body reflows to the PCB top side while tail pins extend through the board to mate with a plug connector from below. This configuration enables board stack heights as low as 5 mm between PCB surfaces, making TSM-123-01-S-DH-A-K-TR well suited for compact module assemblies where top-side clearance is restricted by an enclosure lid or heatsink.
Can TSM-123-01-S-DH-A-K-TR be assembled using standard SMT reflow, or does it need hand soldering?
The TSM-123-01-S-DH-A-K-TR is a surface-mount part designed for paste-and-reflow processing at peak temperatures up to 260°C per IPC/JEDEC J-STD-020. The TR tape-and-reel packaging feeds the connector into automated pick-and-place machines, allowing it to be placed alongside 0402 and 0603 passives and ICs in a single SMT assembly pass without additional hand-soldering steps.
Which Samtec mating connector works with TSM-123-01-S-DH-A-K-TR for a board-to-board connection?
TSM single-row 2.54 mm pitch connectors mate with Samtec SSM-123 single-row socket strips or compatible 0.100 inch pitch female headers with 46 positions. The actual mated engagement depth is determined by the DH tail length — verify the tail protrudes at least 3 mm through the PCB to ensure full socket engagement and an adequate normal force for reliable 46-pin electrical contact at the board interface.
