What are the key features of TSM-139-01-G-DV-P-TR?
- 78-position dual-row layout on 0.100" (2.54 mm) pitch for high-density signal and power distribution across two rows
- Surface mount termination compatible with automated pick-and-place and standard SMT reflow assembly processes
- Dual-row configuration reduces connector length by 50% compared to equivalent single-row strips for compact PCB designs
What is TSM-139-01-G-DV-P-TR used for?
The TSM-139-01-G-DV-P-TR is used in embedded computing boards, industrial control modules, and backplane interconnect systems where 78 signals must be routed through a compact dual-row header. Its 0.100" pitch is compatible with standard ribbon cable and IDC connector assemblies, making it practical for field-wiring and panel-mount control enclosures. Engineers also use it in prototype and evaluation boards as a flexible bus connector for mixed signal and power interfaces.

Frequently Asked Questions
How does the dual-row layout of TSM-139-01-G-DV-P-TR reduce PCB footprint compared to a single-row 78-pin strip?
The TSM-139-01-G-DV-P-TR places 78 pins across 2 rows of 39 contacts each at 0.100" (2.54 mm) pitch, cutting the connector strip length to approximately 99 mm instead of the 198 mm a single-row 78-pin version would require. This halving of strip length is critical for dense backplane designs or multi-connector boards where edge space is limited.
Is TSM-139-01-G-DV-P-TR compatible with standard IDC ribbon cable assemblies for field wiring?
Yes, the 0.100" (2.54 mm) pitch of TSM-139-01-G-DV-P-TR matches the standard IDC ribbon cable pitch, allowing it to mate with common 78-conductor flat ribbon cable assemblies using IDC connectors. This makes it straightforward to connect front-panel wiring harnesses or inter-board ribbon cables in industrial control cabinets without custom cable tooling.
At what supply current and voltage rating can signals be routed through TSM-139-01-G-DV-P-TR in a mixed-signal design?
SAMTEC TSM series terminal strips at 0.100" pitch are typically rated for 3 A per contact at up to 250 V AC/DC for signal and low-power applications. In a mixed-signal design, individual contacts can carry digital I/O signals at 3.3 V or 5 V logic levels alongside analog signals, provided current per pin stays within the 3 A rating and adjacent power pins are derated for thermal balance.
