What are the key features of TSM-142-05-LM-DV-P-TR?
- 84-position dual-row layout at 2.54 mm (.100") pitch provides a large contact count in a familiar standard-pitch footprint
- Low-profile LM tail termination style minimizes connector height above the PCB, benefiting designs with tight vertical clearance
- Dual-voltage (DV) support and tape-and-reel (TR) packaging streamline multi-rail power and high-volume automated assembly workflows
What is TSM-142-05-LM-DV-P-TR used for?
TSM-142-05-LM-DV-P-TR is used in industrial backplane systems, embedded controller motherboards, and test fixture interfaces that require an 84-position dual-row surface mount terminal strip with low-profile termination. Its dual-voltage configuration makes it well suited for mixed 3.3 V / 5 V or 5 V / 12 V power distribution across a single high-density connector body.

Frequently Asked Questions
What is the pitch and row configuration of TSM-142-05-LM-DV-P-TR, and how many contacts are in each row?
TSM-142-05-LM-DV-P-TR is a dual-row connector with 84 total positions, providing 42 contacts per row at a 2.54 mm (.100") pitch. The surface mount dual-row format at standard .100" pitch makes it directly compatible with many through-hole and SMT footprint libraries, simplifying PCB layout for industrial control and embedded computing boards.
How does the LM tail termination of TSM-142-05-LM-DV-P-TR benefit low-clearance PCB designs?
The LM (low-profile metal) tail termination style in TSM-142-05-LM-DV-P-TR keeps the connector's height above the PCB surface lower than standard tail variants, which is critical in stacked-board or chassis-mounted assemblies where vertical clearance between boards is limited to under 10 mm. This tail design also improves solder joint coplanarity across all 84 positions during reflow, reducing tombstoning defects.
Can TSM-142-05-LM-DV-P-TR distribute two independent voltage rails simultaneously, and what is the typical use case?
Yes. The DV (dual-voltage) designation means TSM-142-05-LM-DV-P-TR can distribute 2 independent voltage rails — such as 3.3 V and 5 V, or 5 V and 12 V — through separate contact groups within the same 84-position, 2.54 mm pitch connector body. This is particularly useful in industrial automation backplanes and FPGA development boards that need both a logic supply and a higher-voltage peripheral rail routed through a single connector interface.
