What are the key features of TSM-143-01-STL-DV-P-TR?
- 86-position dual-row SMT terminal strip on 0.100" (2.54 mm) pitch supporting wide signal buses in a single connector body
- Long tail (STL) contact design provides enhanced solder joint standoff and compliance for reliable SMT attachment during thermal cycling
- Dual-voltage (-DV) contacts allow mixed power and signal routing within the same 86-position connector footprint
- Tape-and-reel (-TR) packaging enables automated pick-and-place SMT assembly for high-volume production runs
What is TSM-143-01-STL-DV-P-TR used for?
The TSM-143-01-STL-DV-P-TR is designed for wide-bus backplane connections, multi-signal daughter-card interfaces, and high pin count SMT header applications in industrial computers, communications chassis, and embedded systems. Its 86-position dual-row configuration on a 0.100" pitch allows designers to route large signal buses and power planes through a single connector. The long tail contact and dual-voltage features make it versatile for mixed power and signal environments requiring mechanical robustness.

Frequently Asked Questions
What are the pin count, row configuration, and pitch of the TSM-143-01-STL-DV-P-TR?
The TSM-143-01-STL-DV-P-TR features 86 total positions arranged in 2 rows with 43 contacts per row, at a standard 0.100" (2.54 mm) pitch. At this pitch, the 43-position row spans approximately 106.68 mm in length, making the TSM-143 one of the larger dual-row terminal strips in the TSM series and suitable for applications requiring broad multi-signal bus connectivity in a single SMT component.
How does the STL (long tail) contact variant of the TSM-143-01-STL-DV-P-TR improve solder joint reliability?
The STL long tail contact in the TSM-143-01-STL-DV-P-TR provides a taller solder land interface than standard-length tails, creating more solder volume per joint and additional compliance to absorb PCB-to-connector CTE mismatch during thermal excursions. This is critical for assemblies cycled between -40°C and +85°C, where differential expansion between the FR4 PCB and the connector housing can crack solder joints on shorter-tail variants after fewer than 500 thermal cycles.
In which system designs can the dual-voltage (DV) feature of the TSM-143-01-STL-DV-P-TR reduce total connector count?
The dual-voltage feature of the TSM-143-01-STL-DV-P-TR allows individual contacts to carry either signal-level or power-level currents within the same 86-position connector, reducing the need for separate power and signal connectors. This is especially useful in 3.3 V and 5 V embedded computing backplanes where power rails must be distributed alongside 86 signal lines, potentially eliminating 2 to 4 separate power headers and their associated PCB routing.
What are the sourcing and packaging options for the TSM-143-01-STL-DV-P-TR in a production context?
The TSM-143-01-STL-DV-P-TR is supplied in tape-and-reel format with the -TR suffix, enabling direct loading into automated SMT pick-and-place feeders calibrated for 0.100" pitch components. Samtec typically packages large dual-row terminal strips in reels of 500 to 1,000 pieces depending on the connector body length. Lead times from authorized distributors are generally 8 to 14 weeks for non-stocked quantities, so design teams should factor in this timeline when planning production ramp schedules.
