What are the key features of TSM-143-03-STL-DV-P-TR?
- 86-position dual-row layout at 2.54 mm (0.100 inch) pitch delivering high contact density for surface mount board interconnection
- Straight lead (STL) termination ensuring coplanarity below 0.1 mm across all 86 contacts for reliable SMT reflow soldering
- Tape-and-reel (TR) packaging compatible with automated pick-and-place equipment for high-volume SMT production lines
- Vertical dual-row (DV) orientation enabling compact PCB footprint for efficient signal bus routing on dense embedded boards
What is TSM-143-03-STL-DV-P-TR used for?
The TSM-143-03-STL-DV-P-TR is used in FPGA development boards, industrial backplane systems, and embedded computing modules requiring 86-position SMT header connectivity with guaranteed coplanarity. Its dual-row 2.54 mm pitch layout is ideal for data acquisition systems, communication interface boards, and test fixture connections. The straight-lead termination and tape-and-reel packaging make it well-suited for automated high-volume PCB manufacturing environments.

Frequently Asked Questions
How does the straight lead (STL) termination of TSM-143-03-STL-DV-P-TR improve reflow soldering yield?
The STL suffix specifies straight lead termination on TSM-143-03-STL-DV-P-TR, ensuring all 86 contact pins are coplanar within a tolerance typically below 0.1 mm across the full connector body length of approximately 55 mm. This tight coplanarity is critical for simultaneous solder joint formation across all 86 pads in a single SMT reflow pass, reducing the risk of open circuits or cold joints caused by lifted leads. This makes it suitable for automated reflow at oven peak temperatures up to 260°C.
What is the difference between TSM-143-03-STL-DV-P-TR and TSM-143-02-G-DV-P-TR, and when should each be chosen?
TSM-143-03-STL-DV-P-TR uses straight lead termination with a standard contact finish, while TSM-143-02-G-DV-P-TR features gold-plated contacts across its 86 positions at the same 2.54 mm pitch. The STL variant is preferred for applications where coplanarity and solderability are the primary concerns, and mating cycle count is low. The G-plated variant is chosen when low contact resistance below 10 milliohms and resistance to corrosion over hundreds of mating cycles are required, such as in test sockets or field-replaceable module connectors.
For a parallel memory bus design, how does TSM-143-03-STL-DV-P-TR accommodate address and data lines efficiently?
The 86-position dual-row layout of TSM-143-03-STL-DV-P-TR at 2.54 mm pitch can simultaneously carry a 64-bit data bus, a 16-bit address bus, plus 6 pins for power, ground, and control signals within a single connector. This consolidation simplifies PCB routing on embedded processor boards operating at 3.3 V logic levels, avoids stub-length mismatches that occur when multiple smaller connectors are used, and reduces total connector BOM cost for memory interface and backplane designs.
What tape-and-reel specifications and minimum order quantities apply to TSM-143-03-STL-DV-P-TR?
The TR suffix confirms TSM-143-03-STL-DV-P-TR ships in tape-and-reel format with reel quantities typically of 250 to 500 pieces per reel per SAMTEC's packaging standard for the TSM series. The tape-and-reel format uses a carrier tape pocket pitch compatible with standard SMT feeder widths, enabling uninterrupted pick-and-place loading. Distributors including Digi-Key and Mouser stock this part with minimum order quantities as low as 1 reel, supporting both prototype and mass-production procurement.
