What are the key features of TSM-114-04-STL-DH-P-TR?
- 28 contacts in dual-row 0.100" (2.54 mm) pitch with through-lead (STL) termination for secure PCB footprint registration and solderability
- Dual-height (DH) configuration provides mechanical keying to prevent incorrect board orientation during stacked PCB assembly
- Gold-plated contact finish ensures low contact resistance and long insertion life in industrial and communications applications
- Tape-and-reel (TR) packaging with SMT-compatible footprint supports high-volume automated pick-and-place PCB assembly
What is TSM-114-04-STL-DH-P-TR used for?
The TSM-114-04-STL-DH-P-TR is used in board-to-board interconnect applications within embedded computing modules, industrial control cards, and test fixtures where 28 signal or power lines must be reliably connected at a standard 0.100" pitch. Its STL through-lead configuration and dual-height keying make it well suited for stacked PCB designs in telecom equipment, data acquisition systems, and ruggedized instrument daughter cards.

Frequently Asked Questions
What does the STL suffix indicate about the TSM-114-04-STL-DH-P-TR termination style, and why does it matter for soldering?
The STL suffix designates a through-lead termination style, meaning the connector contacts extend through the PCB and are soldered on the opposite side rather than relying solely on surface pads. This through-lead design increases solder joint mechanical strength by approximately 3× compared to a pure SMT solder joint, making the TSM-114-04-STL-DH-P-TR more resistant to PCB flexure and vibration in ruggedized industrial and embedded computing applications where board stress is a concern.
How many positions does the TSM-114-04-STL-DH-P-TR provide, and how does that compare to the TSM-126 in the same family?
The TSM-114-04-STL-DH-P-TR provides 28 positions (14 per row) in a dual-row 0.100" pitch configuration, compared to 52 positions (26 per row) on the TSM-126. The TSM-114 body is correspondingly shorter—approximately 36.6 mm long versus 66.6 mm for the TSM-126—making it a better fit for applications where fewer than 30 signal lines are needed and board space or connector height along the edge of the PCB must be minimized.
Can TSM-114-04-STL-DH-P-TR be used to route both power and signal lines simultaneously?
Yes. SAMTEC TSM series terminal strips are rated at approximately 1 A per contact at 25°C ambient temperature, and with 28 contacts available, several adjacent pins can be ganged for higher-current power rails. For example, connecting 3 adjacent pins to a 3.3 V power rail allows up to 3 A of continuous load current within thermal derating limits, while the remaining 25 contacts carry digital signals at 0.1 A or less, enabling a single TSM-114 connector to serve as the sole board interconnect for a mixed power-and-signal mezzanine card.
Why does tape-and-reel packaging improve production yield for TSM-114-04-STL-DH-P-TR compared to loose bulk packaging?
Tape-and-reel packaging positions each 28-pin TSM-114-04-STL-DH-P-TR at a fixed orientation on a 24 mm or 32 mm carrier tape with a consistent pitch of 24 mm to 32 mm between parts, enabling automated pick-and-place machines to achieve placement accuracy within ±0.05 mm. Compared to loose bulk packaging where components may tangle or flip, tape-and-reel reduces placement defect rates in automated lines by over 90%, directly improving first-pass yield and reducing rework cost in high-volume PCB production.
