What are the key features of TSM-141-04-SS-DV-P-TR?
- 82-position dual-row SMT terminal strip at 0.100" (2.54 mm) standard pitch for high-density legacy-compatible PCB headers
- Stainless-steel (SS) plated contacts provide corrosion resistance and durability in harsh environments with repeated mating cycles
- Dual-row via-post (DV) termination anchors the connector through PCB vias, delivering superior pull-out strength over pure SMT mounting
- Tape-and-reel (TR) packaging enables automated SMT placement for high-volume production of industrial and communication boards
What is TSM-141-04-SS-DV-P-TR used for?
The TSM-141-04-SS-DV-P-TR is used in industrial control panels, server backplanes, and rugged embedded computing boards where an 82-position dual-row 0.100" pitch connector with enhanced mechanical retention is required. Its stainless-steel contact finish and DV via-post termination make it well-suited for harsh industrial environments and test-and-measurement fixtures that undergo frequent mating cycles at the 2.54 mm standard pitch. The tape-and-reel format supports high-throughput automated SMT production of telecommunications cards and military electronics modules requiring reliable multi-pin surface-mount connections.

Frequently Asked Questions
What makes the stainless-steel contact finish of the TSM-141-04-SS-DV-P-TR different from gold-plated alternatives in harsh environments?
Stainless-steel (SS) plating on the TSM-141-04-SS-DV-P-TR contacts offers superior corrosion and wear resistance compared to standard tin plating, making it suitable for humid, chemically active, or high-cycle industrial environments. While gold provides lower contact resistance below 20 mΩ for low-level signal applications, the SS finish is preferred for power and control connections where mechanical durability across thousands of mating cycles outweighs the marginal resistance difference.
How does the DV via-post termination style improve the mechanical robustness of the TSM-141-04-SS-DV-P-TR on a PCB?
The DV (dual-row via-post) termination feeds the connector's 82 contact tails through matched PCB vias, adding shear and pull-out resistance that pure SMT solder joints on pads alone cannot provide. This is particularly important in vibrating machinery, rack-mounted equipment, and portable rugged instruments operating at 0.100" (2.54 mm) pitch, where the connector may experience perpendicular or lateral mechanical loads during use.
In what types of high-pin-count interconnect architectures is the TSM-141-04-SS-DV-P-TR most commonly used?
The TSM-141-04-SS-DV-P-TR's 82-position count at 2.54 mm pitch is commonly used in FPGA prototyping headers, VME backplane edge connectors, embedded CPU module expansion slots, and industrial PLC I/O interface boards. These architectures require 80 or more signal and power connections on a 0.1" grid while benefiting from the SMT reflow assembly process rated up to 260 °C per IPC/JEDEC J-STD-020 standards.
When is the TSM-141-04-SS-DV-P-TR preferred over the similarly configured TSM-144-02-G-DV-P-TR?
The TSM-141-04-SS-DV-P-TR's 82 positions and stainless-steel finish are preferred over the 88-position gold-plated TSM-144-02 when the design requires slightly fewer pins and prioritizes mechanical durability over minimizing contact resistance. Applications such as field-service test headers or industrial I/O boards with 82 signals benefit from the SS contact's resistance to repeated mechanical stress rather than the low milliohm contact resistance that gold plating provides.
