What are the key features of TSM-143-04-SS-DV-P-TR?
- 86-position dual-row layout at 2.54 mm (0.100 inch) pitch provides high pin-count SMT interconnection in a standard footprint
- Dual SMT stabilizers (SS) improve mechanical retention and prevent connector tilt or rotation during reflow soldering
- Tape-and-reel (TR) packaging ensures compatibility with automated pick-and-place equipment for high-volume SMT production
What is TSM-143-04-SS-DV-P-TR used for?
The TSM-143-04-SS-DV-P-TR is used in high-density board-to-board and wire-to-board interconnect applications in industrial control systems, modular embedded computing, and data acquisition equipment. Its dual SMT stabilizers provide superior mechanical alignment and retention during reflow, reducing solder defect rates on high-pin-count assemblies. The 86-position 2.54 mm pitch configuration is a standard interface in backplane and expansion card designs across automation and instrumentation platforms.

Frequently Asked Questions
What is the contact count and pitch of the TSM-143-04-SS-DV-P-TR, and how are the contacts arranged?
The TSM-143-04-SS-DV-P-TR has 86 total contacts arranged in a dual-row surface mount configuration at a 2.54 mm (0.100 inch) pitch, providing 43 contacts per row. This standard-pitch dual-row layout is compatible with a broad range of mating connectors and cable assemblies used in industrial, embedded, and data acquisition board designs.
What do the SS stabilizers on TSM-143-04-SS-DV-P-TR do and how do they improve assembly yield?
The SS (dual SMT stabilizer) feature adds two mechanical plastic feet that contact the PCB surface during reflow, preventing the connector body from tilting due to paste surface tension on 86-pin pads. This stabilization reduces co-planarity deviation to within 0.1 mm or less, lowering the incidence of tombstoning and solder bridging defects that are common with unsupported high-pitch-count SMT connectors.
How does TSM-143-04-SS-DV-P-TR compare to a similar 86-position through-hole connector in terms of PCB assembly process?
Unlike through-hole connectors requiring wave soldering or selective soldering at temperatures above 260°C, the TSM-143-04-SS-DV-P-TR uses surface-mount terminations that are reflow-soldered at a typical peak temperature of 245°C to 255°C. SMT reflow enables single-pass assembly with other surface-mount components, reduces assembly cycle time, and avoids the cost of a separate wave solder step for this 86-position connector.
Is TSM-143-04-SS-DV-P-TR available in reel format suitable for lean production scheduling?
Yes, the TR suffix confirms the TSM-143-04-SS-DV-P-TR is packaged in tape-and-reel format, typically supplied on reels of 500 or 1000 units. This packaging supports just-in-time delivery to SMT lines, where feeders are loaded directly from the reel, enabling continuous high-throughput placement of this 86-position connector with minimal operator intervention.
