What are the key features of TSM-144-03-S-DV-P-TR?
- 88-position dual-row 0.100" (2.54 mm) pitch layout for high-density SMT board interconnect
- Single-ended (S) contacts with dual-voltage (DV) rating supporting mixed 3.3 V and 5 V signal planes
- Polarization key (-P) prevents 180-degree mis-mating, reducing field-assembly errors
- Tape-and-reel (-TR) packaging optimized for automated pick-and-place SMT production lines
What is TSM-144-03-S-DV-P-TR used for?
The TSM-144-03-S-DV-P-TR serves as a high-pin-count board-to-board interconnect in embedded computing platforms, industrial controllers, and communications backplanes where 88 signals must bridge two PCBs at 0.100" pitch. The single-ended contact style suits digital bus, GPIO expansion, and low-speed analog signal routing without the additional impedance constraints of differential pairs. Polarized dual-voltage capability makes it a reliable drop-in solution for systems combining 3.3 V logic and 5 V I/O in a single connector interface.

Frequently Asked Questions
How does TSM-144-03-S-DV-P-TR differ from TSM-144-04-FM-DV-P-TR in contact style?
The TSM-144-03-S-DV-P-TR uses single-ended (S) contacts, meaning each of the 88 positions carries an independent signal or supply path at up to 5 V. The -04-FM variant uses a female-male (FM) configuration instead. Both share the same 0.100" (2.54 mm) dual-row pitch and 88-position count, so the footprint is identical and only the contact engagement geometry differs.
For a 88-signal parallel data bus on a single-board computer, how does this connector handle signal integrity?
At the 0.100" (2.54 mm) pitch used by the TSM-144-03-S-DV-P-TR, single-ended contacts maintain adequate isolation for parallel buses operating below 50 MHz clock rates. The dual-row arrangement places ground or supply returns within one row of any signal pin, limiting crosstalk and keeping signal integrity suitable for 8-bit or 16-bit wide data buses common in embedded SOM and carrier-board designs.
What reel quantity and placement rate can be expected for TSM-144-03-S-DV-P-TR in SMT production?
Tape-and-reel packaging for the TSM-144-03-S-DV-P-TR typically ships in reel quantities of 250 to 500 pieces, compatible with standard 24 mm or 32 mm SMT feeders. Automated pick-and-place machines can achieve placement rates of several thousand parts per hour, making this 88-position connector cost-effective for production runs of 1,000 boards or more.
When should a designer choose the TSM-144-03-S-DV-P-TR over a wire-to-board connector for the same 88-signal interface?
Board-to-board SMT connectors like the TSM-144-03-S-DV-P-TR are preferred over wire-to-board solutions when mating stiffness must stay below 50 N insertion force, board spacing is fixed at a defined stack height, and signal count exceeds 40 pins — managing 88 wires in a harness adds weight and assembly cost far beyond the compact 2.54 mm pitch SMT footprint of this terminal strip.
