What are the key features of TSM-139-02-TL-DV-P-TR?
- 78-position dual-row configuration at 0.100" (2.54 mm) pitch enabling high-density SMT signal routing
- Top-loaded (-TL) contact entry design for simplified mating and positive connector engagement on PCB
- Tape-and-reel (-TR) packaging supporting automated pick-and-place equipment in high-volume SMT production lines
What is TSM-139-02-TL-DV-P-TR used for?
The TSM-139-02-TL-DV-P-TR is designed for demanding SMT applications in industrial control, communications backplanes, and data acquisition systems requiring 78 positions at 0.100 inch pitch. Its top-loaded contact entry ensures reliable mating in confined PCB spaces and in automated assembly environments. The dual-voltage configuration supports mixed-voltage designs with separate 3.3 V and 5 V signal planes on a single connector.

Frequently Asked Questions
How many positions and what pitch does the TSM-139-02-TL-DV-P-TR provide for SMT board layouts?
The TSM-139-02-TL-DV-P-TR offers 78 positions arranged in a dual-row format at 0.100 inch (2.54 mm) pitch. This configuration delivers high signal density in a compact SMT footprint suitable for industrial control and communications boards.
What advantage does the top-loaded contact design offer in the TSM-139-02-TL-DV-P-TR?
The top-loaded (-TL) contact entry on the TSM-139-02-TL-DV-P-TR provides a positive engagement point that simplifies mating in confined board assemblies. Compared to side-entry designs, top loading reduces insertion force variance and improves reliability in automated production environments handling 78-position connectors.
For a backplane design needing mixed 3.3 V and 5 V planes, why is the TSM-139-02-TL-DV-P-TR a good fit?
The -DV (dual-voltage) option in the TSM-139-02-TL-DV-P-TR allows two electrically isolated voltage planes within the single 78-position, 0.100 inch pitch connector body. This eliminates the need for 2 separate connectors to handle 3.3 V and 5 V rails, saving board space and reducing part count.
How does tape-and-reel packaging affect procurement and assembly for the TSM-139-02-TL-DV-P-TR?
The -TR designation confirms tape-and-reel packaging, which is compatible with standard SMT pick-and-place machines running at speeds above 1000 placements per hour. This reduces manual handling errors and simplifies JIT purchasing for production runs requiring hundreds or thousands of connectors per batch.
