What are the key features of TSM-143-01-TM-DV-P-TR?
- 86-position dual-row layout at 0.100 inch (2.54 mm) pitch providing industry-standard 2.54 mm grid compatibility for broad PCB tooling and footprint reuse
- Top-mount (TM) termination style enabling vertical signal routing from the connector directly into the PCB plane for low-profile stacking applications
- Dual-voltage (DV) and polarized (P) keying preventing incorrect mating in mixed power-and-signal backplane designs with multiple voltage rails
- Tape-and-reel (TR) packaging supporting automated pick-and-place assembly at high production volumes with standard SMT feeder equipment
What is TSM-143-01-TM-DV-P-TR used for?
TSM-143-01-TM-DV-P-TR is used in SBC expansion backplanes, industrial I/O carrier boards, and high-density signal distribution modules where a reliable 86-position 2.54 mm pitch SMT terminal strip with top-mount geometry is required. Its dual-voltage polarized keying suits backplane designs carrying 3.3 V, 5 V, and 12 V rails alongside high-speed differential signal pairs on the same connector. The tape-and-reel format streamlines automated assembly of telecom and embedded computing boards in high-volume manufacturing environments.

Frequently Asked Questions
How does the top-mount (TM) termination of TSM-143-01-TM-DV-P-TR differ from standard through-hole or right-angle alternatives?
The top-mount termination style means solder tails exit vertically from the top of the connector body rather than bending 90 degrees (right-angle) or passing through the PCB (through-hole), allowing the 86-position strip to be placed and reflowed on the PCB surface while routing signals straight down into the board plane for a lower overall stack height compared to right-angle variants.
What is the contact pitch and total position count of TSM-143-01-TM-DV-P-TR and what board grid does this match?
TSM-143-01-TM-DV-P-TR has 86 total positions in a dual-row configuration at 0.100 inch (2.54 mm) pitch per contact, matching the universal 2.54 mm engineering grid used by the vast majority of through-hole and SMT development boards, backplane slots, and Eurocard connectors, ensuring broad mechanical and footprint compatibility.
What does the dual-voltage polarized (DV-P) designation mean for board-to-board backplane designs using TSM-143-01-TM-DV-P-TR?
DV (dual-voltage) indicates the connector body is keyed to accommodate two supply rails on the same 86-pin connector, while the P (polarized) suffix adds a mechanical asymmetry to the housing that physically prevents 180-degree rotation of the mating plug, protecting boards from reversed 5 V and 3.3 V power rails that would immediately damage ICs in a 2-rail backplane system.
Which mating connector socket is recommended for pairing with TSM-143-01-TM-DV-P-TR and what retention force can be expected?
TSM-143-01-TM-DV-P-TR pairs with SAMTEC SSM or SFM series 0.100-inch (2.54 mm) pitch dual-row socket strips, providing a per-contact mating force in the range of 0.1 N to 0.4 N for each of the 86 positions, giving a total connector insertion force of approximately 8 N to 34 N and a retention force sufficient to resist accidental unmating under 5 G shock loads.
