What are the key features of TSM-139-04-L-DV-P-TR?
- 78-position dual-row layout at 0.100" (2.54 mm) pitch supports high pin-count board-to-board and wire-to-board interconnects
- Surface-mount termination with tape-and-reel (TR) packaging ensures compatibility with automated high-volume pick-and-place assembly lines
- Dual-voltage (DV) option accommodates mixed-signal boards handling both logic-level and power signals in a single connector
What is TSM-139-04-L-DV-P-TR used for?
The TSM-139-04-L-DV-P-TR is suited for industrial backplane connectors, embedded controller boards, and test fixture interfaces requiring 78 positions at the widely adopted 0.100" pitch. Its surface-mount dual-voltage design supports mixed logic and power rails on the same board, reducing connector count. Tape-and-reel packaging makes it practical for high-volume automated assembly in consumer and industrial electronics manufacturing.

Frequently Asked Questions
What pitch and position count characterizes the TSM-139-04-L-DV-P-TR terminal strip?
The TSM-139-04-L-DV-P-TR features 78 positions in a dual-row arrangement at 0.100" (2.54 mm) pitch, with 39 contacts per row. This standard 2.54 mm pitch aligns with conventional 0.1" grid PCB designs, making it straightforward to route traces and fan out signals on 2-layer and 4-layer boards used in industrial control and instrumentation.
How does the tape-and-reel (TR) option benefit high-volume PCB manufacturing with TSM-139-04-L-DV-P-TR?
The TR (tape-and-reel) packaging option for TSM-139-04-L-DV-P-TR enables automated SMT pick-and-place assembly on standard reel feeders without manual component loading. This reduces placement cycle time for lines assembling hundreds of boards per hour, improving throughput and minimizing placement errors on 78-pin connectors where manual positioning would be slow and unreliable.
When should engineers choose the TSM-139-04-L-DV-P-TR over a 0.050" pitch alternative for their design?
Engineers should select TSM-139-04-L-DV-P-TR when PCB design rules allow 0.100" (2.54 mm) pitch routing and signal density requirements do not mandate sub-mm pitch connectors. The 2.54 mm pitch simplifies PCB trace routing between rows, enables 100-mil grid component placement, and reduces crosstalk risk compared to 0.050" pitch alternatives carrying 78 signals over the same connector length.
