What are the key features of TSM-107-03-LM-DH-A-K-TR?
- 14-position 0.100" pitch surface mount terminal strip with dual-height (DH) contacts enabling flexible mating clearance in multi-board stacking configurations
- Low-profile SMT footprint with tape-and-reel (TR) packaging designed for automated pick-and-place reflow assembly on standard SMT production lines
- SAMTEC TSM series stamped contacts with A (right-angle or angled) configuration and K keying feature for polarized, error-proof mating in 14-pin wire-to-board applications
What is TSM-107-03-LM-DH-A-K-TR used for?
The TSM-107-03-LM-DH-A-K-TR is suited for embedded microcontroller expansion headers, sensor breakout boards, and industrial fieldbus interface modules where 14 positions of organized SMT wire-to-board connectivity are required at 0.100" pitch. Its keyed (K) and dual-height (DH) design prevents incorrect mating, making it valuable in field-replaceable module assemblies subject to maintenance operations.

Frequently Asked Questions
What does the DH designation indicate about the TSM-107-03-LM-DH-A-K-TR contact height compared to standard TSM series strips?
The DH designation stands for dual-height contacts, meaning the TSM-107-03-LM-DH-A-K-TR has contacts with two distinct height levels across the 14-position array. This dual-height feature provides additional mating clearance or differential mating depth suited for multi-board stacking configurations at 0.100" pitch where a single contact height would cause interference or insufficient engagement.
How does the K keying option on the TSM-107-03-LM-DH-A-K-TR protect against incorrect connector insertion in field applications?
The K keying option adds a physical polarizing key to the 14-position connector housing that prevents the mating cable assembly from being inserted incorrectly or rotated 180 degrees. This is critical for field-replaceable modules at 0.100" pitch where technicians may connect harnesses without visual confirmation, reducing the risk of 14-pin signal reversal damage.
For a 14-position SMT connector at 0.100" pitch, when should a designer choose TSM-107-03-LM-DH-A-K-TR over a standard non-keyed alternative?
A designer should choose the TSM-107-03-LM-DH-A-K-TR over a non-keyed alternative whenever the 14-pin wire-to-board interface will be accessed by maintenance technicians or end users who may not follow PCB polarity markings. The K keying prevents costly mismating errors on boards powered by 3.3 V or 5 V rails, and the DH dual-height contacts add robustness in applications subject to vibration or repeated mating cycles.
