What are the key features of TSM-143-02-TM-DV-P-TR?
- 86-position dual-row SMT terminal strip at 2.54 mm (0.100 inch) pitch for high pin-count board-to-board connections
- Through-mount (TM) termination style provides additional mechanical anchor points for enhanced connector stability on the PCB
- Dual-voltage (DV) configuration enables simultaneous assignment of multiple voltage rails and signal lines across 86 positions
- Tape-and-reel (TR) packaging enables high-throughput automated pick-and-place assembly for volume production
What is TSM-143-02-TM-DV-P-TR used for?
The TSM-143-02-TM-DV-P-TR is suited for high pin-count SMT board connection applications in industrial backplanes, embedded computing modules, and test equipment requiring 86 reliable contact points at standard 2.54 mm pitch. Its through-mount termination provides improved pull strength compared to surface-only SMT pads, making it well suited for connectors that experience mechanical stress during repeated mating cycles. The dual-voltage pin assignment flexibility supports complex power distribution and signal interface designs across the 86-position array.

Frequently Asked Questions
How does the through-mount (TM) termination of TSM-143-02-TM-DV-P-TR improve mechanical performance versus standard surface mount termination?
Through-mount (TM) termination adds mechanical anchor tails that pass through PCB vias in addition to the surface mount solder pads, increasing the total pull-out force by 2x to 3x compared to surface-only termination at the same pitch. For an 86-position connector at 2.54 mm pitch, this additional anchoring significantly reduces the risk of pad lift or connector tilt during repeated mating and unmating operations, which is critical in backplane and test fixture applications.
With 86 positions at 2.54 mm pitch, how long is the PCB footprint of TSM-143-02-TM-DV-P-TR per row?
Each row of the TSM-143-02-TM-DV-P-TR spans 43 positions at 2.54 mm (0.100 inch) pitch, resulting in a row length of approximately 107.9 mm (43 × 2.54 mm). This footprint length must be reserved in the PCB layout along with a minimum clearance of 1.0 mm to 2.0 mm on each side of the connector body, so the total keep-out zone in the connector axis exceeds 110 mm for a full 86-position dual-row terminal strip.
How should dual-voltage (DV) pin assignments be allocated across the 86 positions to minimize noise coupling in mixed signal and power designs?
In a dual-voltage (DV) design with 86 positions, a recommended practice is to allocate power pins such as 3.3 V, 5 V, and ground at one or both ends of each row, separated from high-speed signal pins by at least 2 dedicated ground pins on each side. With 2.54 mm spacing, this separation keeps power and high-speed signal return paths adjacent, reducing the loop inductance of power delivery and minimizing crosstalk at frequencies up to several hundred MHz on the signal pins.
When would TSM-143-02-TM-DV-P-TR be selected over TSM-142-04-SM-DV-P-TR for a backplane design?
TSM-143-02-TM-DV-P-TR with 86 positions is chosen when the interface requires 2 more contacts than the 84-position TSM-142-04-SM-DV-P-TR, such as when additional ground pins or power supply pins cannot be eliminated from the pin assignment. The through-mount (TM) termination of the 143 variant also offers stronger mechanical retention than staggered-mount (SM) designs in applications where the connector faces high peel force or vibration loads above 5 G.
