What are the key features of TSM-139-01-H-DV-P-TR?
- 78 positions in dual-row 2.54 mm (0.100") pitch SMT format provides industry-standard footprint compatibility for dense PCB signal routing
- High-profile contact height variant offers increased board-to-board or component clearance compared to standard-profile terminal strips
- Surface mount termination simplifies PCB assembly with standard reflow soldering, making it suitable for high-volume automated production
What is TSM-139-01-H-DV-P-TR used for?
TSM-139-01-H-DV-P-TR is suited for backplane interconnects, industrial I/O modules, and test fixture boards that require 78-position dual-row 2.54 mm pitch SMT terminal strips. The high-profile design accommodates component overhang or cable routing between mating boards in stacked PCB assemblies. It is also used in data acquisition systems and embedded control modules where a large number of signal lines must be distributed across a single SMT connector footprint.

Frequently Asked Questions
How many positions does the TSM-139-01-H-DV-P-TR provide and what pitch does it use?
The TSM-139-01-H-DV-P-TR provides 78 positions arranged in 2 rows of 39 contacts each, at a 2.54 mm (0.100 inch) pitch. This industry-standard pitch ensures broad compatibility with mating terminal strips and headers, covering 78 signal or mixed power lines in a single SMT footprint on the PCB.
What PCB assembly advantage does the high-profile variant of TSM-139-01-H-DV-P-TR offer compared to low-profile terminal strips?
The high-profile (H) contact height provides additional vertical clearance of several millimetres above the PCB surface compared to standard or low-profile variants. This extra clearance prevents adjacent tall components, cable bundles, or overlapping boards from interfering with the connector body, reducing mechanical stress on solder joints and improving long-term reliability in vibration-prone environments.
In which backplane or stacked PCB configurations is the TSM-139-01-H-DV-P-TR commonly specified?
The TSM-139-01-H-DV-P-TR is commonly specified in industrial automation backplanes, telecom line card motherboards, and multi-board embedded computing systems where 78-position dual-row 2.54 mm SMT terminal strips are required. Its large position count handles simultaneous routing of address, data, control, power, and ground signals in a single component, reducing connector count on complex backplane designs with 64-bit or wider bus interfaces.
