Key Features
- 78-position dual-row layout with 0.100" (2.54 mm) pitch for high-contact-count SMT terminal strip connectivity
- Surface mount termination compatible with automated pick-and-place and reflow assembly processes
- Dual vertical (DV) tail option provides flexible wire or cable termination for board-to-wire assemblies
- Standard 2.54 mm pitch ensures compatibility with common connectors and cable harness assemblies
Applications
The TSM-139-02-F-DV-P-TR is used in industrial control panels, test and measurement equipment, and embedded systems where 78 signal connections must be made via a compact SMT terminal strip at standard 2.54 mm pitch. Its dual-row configuration allows connection of ribbon cables, IDC harnesses, and wire bundles to PCBs in a single connector footprint. The part is also deployed in prototype and low-volume production boards where 0.100" pitch terminal strips facilitate easy cable attachment and field servicing.

Frequently Asked Questions
How many positions and what pitch does the TSM-139-02-F-DV-P-TR terminal strip provide?
The TSM-139-02-F-DV-P-TR provides 78 total positions in a dual-row layout with 0.100" (2.54 mm) pitch, giving 39 contacts per row. This standard 2.54 mm pitch is compatible with common IDC ribbon cables and wire harnesses, making it straightforward to mate with 78-way or sub-divided cable assemblies in industrial and prototype applications.
What termination style does the TSM-139-02-F-DV-P-TR use, and what assembly advantages does it provide?
The TSM-139-02-F-DV-P-TR uses surface mount (SMT) termination with dual vertical (DV) tails, enabling placement by standard pick-and-place equipment followed by reflow soldering. No through-hole drilling is required for the 78-position footprint, reducing PCB fabrication cost. The DV tail configuration also accommodates angled wire entry for board-to-wire assemblies in enclosures with limited vertical clearance above the PCB.
In what applications does the TSM-139-02-F-DV-P-TR deliver the best value over a pin header strip?
The TSM-139-02-F-DV-P-TR outperforms a simple 2.54 mm pin header in applications requiring simultaneous SMT mounting and wire termination, such as industrial field-wiring panels and test jig interfaces. Its terminal strip design accepts stripped wire leads directly into the 78-position contact array, eliminating the need for crimp housings or separate mating connectors on cable ends — reducing total assembly BOM by up to 2 additional components per connector pair.
How does the dual-row 0.100" pitch of the TSM-139-02-F-DV-P-TR compare to a single-row configuration for the same 78-contact count?
A dual-row layout at 0.100" pitch fits 78 contacts in a connector body approximately 50 mm long (39 positions × 2.54 mm), whereas a single-row arrangement would require a 100 mm body length for the same count. The dual-row TSM-139 design halves the PCB edge length needed, which is critical in 100 mm or 160 mm Eurocard form factors where connector real estate along the card edge is tightly constrained.
