What are the key features of TSM-138-04-TL-DV-P-TR?
- 76-position dual-row SMT terminal strip on standard 0.100" (2.54 mm) pitch for dense signal routing
- Dual-voltage (DV) compatibility supports mixed-voltage board designs in a single connector footprint
- Tape-and-reel (TR) packaging enables high-volume automated pick-and-place assembly on SMT production lines
What is TSM-138-04-TL-DV-P-TR used for?
The TSM-138-04-TL-DV-P-TR is used in industrial control boards, embedded computing modules, and test instrument backplanes where 76 signal connections must be made in a compact SMT dual-row footprint. Its 0.100-inch pitch and tape-and-reel packaging suit automated high-volume PCB assembly while the dual-voltage design accommodates 3.3 V and 5 V mixed-logic systems on a single connector. The surface-mount termination simplifies board layout by eliminating through-hole drilling requirements.

Frequently Asked Questions
What position count and pitch does the TSM-138-04-TL-DV-P-TR provide, and how are the contacts arranged?
The TSM-138-04-TL-DV-P-TR provides 76 positions arranged in a dual-row (2 x 38) configuration on a 0.100-inch (2.54 mm) pitch. This layout routes 76 signals through a connector body roughly 96.5 mm long, offering high signal density for dual-row SMT designs in industrial control and embedded computing boards.
How does dual-voltage (DV) compatibility on the TSM-138-04-TL-DV-P-TR benefit mixed-logic PCB designs?
The dual-voltage (DV) designation means the TSM-138-04-TL-DV-P-TR can carry both 3.3 V and 5 V signals across its 76 positions without requiring separate connectors for each voltage domain. This simplifies board design by consolidating mixed-logic I/O — such as 5 V legacy bus signals and 3.3 V FPGA I/O lines — into a single 2.54 mm pitch connector, reducing component count and PCB area.
Why does the tape-and-reel (TR) packaging of the TSM-138-04-TL-DV-P-TR matter for production efficiency?
Tape-and-reel packaging allows the TSM-138-04-TL-DV-P-TR to be loaded directly onto standard SMT pick-and-place machines, eliminating the manual feeder loading required for tray or tube-packaged connectors. For a production run of 10,000 boards, automated feeding can reduce connector placement time by more than 80% compared to manual placement, while also improving placement accuracy on 2.54 mm pitch pads.
