What are the key features of TSM-103-03-STL-DH-A-K-TR?
- 6-position dual-row layout at 0.100" (2.54 mm) pitch provides a compact 3-contacts-per-row interface compatible with standard 2.54 mm grid PCBs and ribbon cable headers
- Short-tail (STL) lead style reduces solder tail height for low-profile SMT assembly while maintaining reliable wetting at reflow temperatures up to 260°C
- Polarized keying (K) prevents connector mis-insertion during board assembly, and tape-and-reel (TR) packaging enables pick-and-place throughput above 10,000 units per hour
What is TSM-103-03-STL-DH-A-K-TR used for?
The TSM-103-03-STL-DH-A-K-TR is used for compact board-to-board and mezzanine card interconnect in IoT edge devices, microcontroller breakout boards, and industrial sensor modules where a small 6-position dual-row header is required. Its polarized keying feature prevents reversed connections to sensitive 3.3 V or 5 V powered modules during prototype and production assembly. The tape-and-reel format makes it ideal for high-volume automated SMT production lines where manual connector placement would introduce cost and error.

Frequently Asked Questions
What is the position count and contact arrangement of the TSM-103-03-STL-DH-A-K-TR?
The TSM-103-03-STL-DH-A-K-TR has 6 total positions in a dual-row configuration with 3 contacts per row, arranged at 0.100" (2.54 mm) pitch. This layout supports 3 differential pairs or 6 single-ended signals in a compact SMT footprint compatible with standard 2.54 mm grid PCBs.
How does the short-tail (STL) lead style on TSM-103-03-STL-DH-A-K-TR affect PCB assembly?
The short-tail (STL) termination style on the TSM-103-03-STL-DH-A-K-TR reduces the SMT solder tail length compared to standard tails, minimizing the connector's mounting height and enabling low-profile board-to-board stacking configurations. This is critical for assemblies with height constraints below 5 mm between mated boards in compact enclosures.
What current per contact does the TSM-103-03-STL-DH-A-K-TR support and what operating temperatures does it cover?
Each contact in the TSM-103-03-STL-DH-A-K-TR is rated for approximately 1 A continuous current, and the connector operates reliably from -55°C to +125°C. Bussing 2 or 3 contacts together allows delivery of 2 A to 3 A on shared power rails alongside the remaining signal pins.
Which connector families mate with the TSM-103-03-STL-DH-A-K-TR at the 2.54 mm pitch?
The TSM-103-03-STL-DH-A-K-TR mates with SAMTEC's SSW, TSW, and CLM series 6-position dual-row socket strips as well as standard IEC 60603-13 compliant dual-row IDC connectors at 2.54 mm pitch. This broad compatibility ensures procurement flexibility across multiple second-source suppliers without custom connector tooling.
