TSM-144-01-H-DV-P-TR SAMTEC Connector (Other) In Stock
TSM-144-01-H-DV-P-TR is a 88-position dual-row surface-mount terminal strip from Samtec with a 2.54 mm (0.100") pitch, gold-plated contacts, and tape-and-reel packaging for automated assembly. Contacts are rated for 3 A per pin at up to 125 V AC/DC, and the H suffix provides a taller above-board profile for clearance-sensitive layouts. Available from authorized global distributors with in-stock inventory and worldwide shipping.

What are the key features of TSM-144-01-H-DV-P-TR?
- 88-position dual-row SMT layout at 2.54 mm (0.100") pitch with a tall profile (H suffix) for improved board-to-board clearance in stacked assemblies
- Gold-plated contacts rated 3 A per pin and 125 V AC/DC deliver reliable low-resistance connections across high-cycle mating operations
- Tape-and-reel (TR) packaging supports fully automated pick-and-place with lead-free SAC305 reflow compatibility up to 260°C
What is TSM-144-01-H-DV-P-TR used for?
The TSM-144-01-H-DV-P-TR is used on backplane assemblies, industrial control daughter cards, and test-fixture PCBs that need a large-count 2.54 mm pitch dual-row SMT header with additional above-board height for cable routing or heat-sink clearance. Its 88-pin configuration efficiently accommodates mixed power-and-signal routing across a single connector body, reducing total connector count. The tape-and-reel format makes it well-suited for high-volume automated PCB manufacturing lines.

Frequently Asked Questions
How are the 88 positions of the TSM-144-01-H-DV-P-TR distributed across the connector body?
The 88 contacts are arranged as 2 rows of 44 positions each on a 2.54 mm (0.100") pitch, giving a total strip length of approximately 44 × 2.54 mm = 112 mm. The DV designation indicates a dual-row vertical SMT mount, so both rows terminate with surface-mount tails that reflow solder flat onto the PCB pads in a single pass.
What distinguishes the H profile variant of the TSM-144-01-H-DV-P-TR from standard-height TSM connectors?
The H suffix specifies a taller above-board insulator height of approximately 8.89 mm (0.350") compared to the standard 5.84 mm (0.230") TSM body. This extra 3 mm of clearance accommodates ribbon cable exits, heat sinks, or conformal coating buildup on a mating daughter card, eliminating the need for standoffs in stacked PCB systems that need at least 8 mm of board separation.
What current and voltage can each contact in the TSM-144-01-H-DV-P-TR carry continuously?
Each contact is rated for 3 A continuous current and 125 V AC/DC working voltage. At 3 A, the gold-plated contact maintains a resistance below 20 mΩ, producing a voltage drop under 60 mV across the contact interface. Designers can gang multiple adjacent contacts for higher-power rails, for example using 4 pins in parallel to carry a 12 A power supply with comfortable derating margin.
Which mating socket or header series can be plugged into the TSM-144-01-H-DV-P-TR?
The TSM-144 pin strip mates with Samtec SSW, ESW, BCS, and SFM dual-row socket families at the same 2.54 mm pitch and 2×44 count. Industry-standard 0.100" dual-row female headers from other manufacturers are also compatible as long as they match the 44-position-per-row count and 2.54 mm grid. The gold tine plating is rated for up to 100 mate and unmate cycles at low contact force without measurable degradation.
For a modular industrial backplane needing 80+ signal lines, what PCB layout advantages does the TSM-144-01-H-DV-P-TR offer over a fine-pitch alternative?
The 2.54 mm pitch allows a single via and trace to pass between adjacent pads on a 6-mil trace / 6-mil space PCB design rule, avoiding the blind or buried via structure required by 1.00 mm pitch connectors. The 88-pin dual-row footprint can carry all 64 data bus lines, 8 address lines, and several power pins in one 112 mm strip, while the 3 A per pin rating handles 3.3 V and 5 V supply rails without a separate power connector, simplifying the overall backplane layout.
