What are the key features of TSM-140-03-STL-DV-P-TR?
- 80-position dual-row terminal strip on 0.100" (2.54 mm) pitch offers 80 SMT contacts compatible with standard 2.54 mm PCB land patterns
- DV dual-voltage option supports mixed signal and power connections on the same 80-pin connector for versatile board-level interfacing
- P press-fit compliant pin provides a solderless through-board connection option, enabling rework-free installation in backplane and high-reliability assemblies
What is TSM-140-03-STL-DV-P-TR used for?
The TSM-140-03-STL-DV-P-TR is used in backplane interconnects, multi-board computer systems, and industrial control modules requiring 80 channels of dual-voltage SMT connectivity at standard 2.54 mm pitch. Its press-fit pin option and STL low-profile tail make it ideal for high-density rack-mount systems and embedded processor boards where solderless assembly and minimal connector height are priorities.

Frequently Asked Questions
What does the DV (dual-voltage) option mean for the TSM-140-03-STL-DV-P-TR in mixed-signal board designs?
The DV designation on the TSM-140-03-STL-DV-P-TR indicates that the connector housing is configured to accept two different voltage rail connections simultaneously within the same 80-position dual-row body. This allows designers to route both 3.3 V logic signals and 12 V power lines through a single 2.54 mm pitch connector, reducing total connector count and BOM complexity in mixed-signal backplane designs.
How does the P press-fit pin of the TSM-140-03-STL-DV-P-TR eliminate the need for soldering in backplane assemblies?
The P compliant press-fit pin is sized to create an interference fit with a 1.0 mm to 1.1 mm plated through-hole, generating a gas-tight electrical connection without solder. In 80-position dual-row backplane applications, this eliminates the thermal stress of wave soldering on high-layer-count boards, reduces assembly time by approximately 30%, and allows field replacement of individual connector modules.
For a 40-row, 2-column backplane routing 80 signals at 2.54 mm pitch, how long is the TSM-140-03-STL-DV-P-TR footprint on the PCB?
The TSM-140-03-STL-DV-P-TR with 40 positions per row on 0.100" (2.54 mm) pitch occupies approximately 101.6 mm (4.0 inches) in the row direction on the PCB. The dual-row footprint adds one additional 2.54 mm column width, so the overall connector land pattern is about 101.6 mm × 5.08 mm, a compact outline for routing 80 signals in backplane and multi-board compute systems.
