What are the key features of TSM-107-03-STL-DH-A-K-TR?
- 14 dual-row positions at 0.100" (2.54 mm) pitch with a shrouded (SH) housing that guides and protects contacts during mating
- Gold-plated (K option) contacts delivering low, stable contact resistance over extended insertion cycles in demanding applications
- Surface-mount termination in tape-and-reel packaging for high-throughput pick-and-place SMT assembly up to 260°C reflow
What is TSM-107-03-STL-DH-A-K-TR used for?
The TSM-107-03-STL-DH-A-K-TR is used in compact embedded systems, sensor interface boards, and industrial handheld devices where a 14-position dual-row header must be reliably mated and unmated by field technicians. The shrouded housing prevents mis-insertion, and the gold contact finish ensures consistent signal integrity across multiple reconnection events in 2.54 mm pitch applications.

Frequently Asked Questions
Why does the TSM-107-03-STL-DH-A-K-TR include a shrouded housing, and how does it help in field-serviced equipment?
The shrouded (SH) housing on the TSM-107-03-STL-DH-A-K-TR provides a mechanical keying fence that aligns the mating connector and prevents off-by-one pin mis-insertions across all 14 dual-row positions at 2.54 mm pitch. In field-serviced equipment where technicians reconnect boards under time pressure, this shroud dramatically reduces the risk of connector damage and resulting downtime.
How does the gold contact finish on the TSM-107-03-STL-DH-A-K-TR affect signal quality in low-voltage logic interfaces?
The gold-plated K-option contacts maintain contact resistance well below 30 milliohms even after repeated mating, ensuring clean logic transitions at 3.3 V and 5 V signal levels across all 14 positions. For I2C, SPI, or UART interfaces on embedded boards, this low resistance prevents voltage-drop artifacts that could cause data errors on high-speed serial lines.
Is TSM-107-03-STL-DH-A-K-TR a drop-in alternative to similar 14-position dual-row 2.54 mm connectors from other brands?
The TSM-107-03-STL-DH-A-K-TR follows the standard 0.100" (2.54 mm) dual-row footprint used across SAMTEC's TSM series and many competing brands, so the PCB land pattern is typically identical to equivalent 14-position SMT terminal strips from Molex, TE Connectivity, and Würth Elektronik. However, the shrouded housing height and polarization keying must be verified against the mating connector to confirm full mechanical interchangeability.
