What are the key features of TSM-139-05-TM-DV-P-TR?
- 78-position dual-row layout at 0.100" (2.54 mm) pitch, compatible with standard through-hole 0.100" grid footprints in SMT form
- Tape-and-reel (-TR) packaging enables automated pick-and-place assembly at production throughputs exceeding 10,000 components per hour
- Dual-voltage (DV) configuration supports mixed power and signal routing within a single 78-pin surface-mount connector
- Surface-mount termination eliminates 78 through-holes, reducing PCB drilling and plating costs in high-volume manufacturing
What is TSM-139-05-TM-DV-P-TR used for?
The TSM-139-05-TM-DV-P-TR suits high-density industrial control boards, data acquisition backplanes, and embedded processor carrier cards requiring 78 surface-mount connections on a standard 0.100" grid. The tape-and-reel format is optimized for automated SMT production lines assembling large boards with multiple high-pin-count connectors. It is also used in test-and-measurement daughter cards and FPGA evaluation modules where a large mixed-signal connector footprint must be maintained across multiple board revisions.

Frequently Asked Questions
How many positions and at what pitch is the TSM-139-05-TM-DV-P-TR terminal strip configured?
The TSM-139-05-TM-DV-P-TR provides 78 positions arranged in 2 rows of 39 contacts at a 0.100" (2.54 mm) pitch. This dual-row configuration is directly compatible with standard 0.100" grid PCB footprints, allowing designers to migrate existing through-hole layouts to surface-mount form without changing the board's connector placement or routing grid.
Which automated assembly setups benefit from the tape-and-reel (-TR) packaging of this SAMTEC terminal strip?
High-volume SMT pick-and-place lines equipped with feeders for 8 mm or 12 mm tape benefit directly from the -TR format, which presents each 78-pin connector at a consistent orientation for robotic placement at rates above 5,000 units per hour. This eliminates operator handling of loose strip connectors, cutting placement cycle time by at least 30% on boards with multiple TSM connectors compared to tray-fed components.
What is the dual-voltage (DV) configuration in the TSM-139-05-TM-DV-P-TR and when is it needed?
The DV (dual-voltage) suffix indicates that the 78-pin connector body is divided into two electrically separated zones, allowing separate power domains — for example 3.3 V logic and 12 V power — to share the same connector at 0.100" pitch without crossover. This is valuable in industrial motor drive boards and mixed-signal data acquisition systems where routing two voltage domains through a single 78-pin SMT connector saves PCB space compared to using two separate connectors.
Can the TSM-139-05-TM-DV-P-TR withstand standard lead-free reflow soldering profiles?
Yes, the TSM-139-05-TM-DV-P-TR is designed for lead-free reflow soldering with a 260°C peak temperature per IPC/JEDEC J-STD-020. At 0.100" (2.54 mm) pitch, solder paste stencils with 1.0 mm x 1.5 mm apertures deliver adequate paste volume for reliable fillets on all 78 surface-mount terminations. SAMTEC rates this terminal strip for at least 2 reflow cycles without degradation of mechanical retention or contact integrity.
