Frequently Asked Questions
How many positions and rows does TSM-139-03-TM-DV-P-TR provide, and what is the pin pitch?
TSM-139-03-TM-DV-P-TR provides 78 total positions in a dual-row layout with 39 pins per row on a standard 0.100 inch (2.54 mm) pitch. This pitch is compatible with the most common PCB grid spacing used in embedded computing, industrial I/O, and legacy system interfaces.
What does the DV designation in TSM-139-03-TM-DV-P-TR mean for mixed signal and power applications?
The DV (dual-voltage) designation in TSM-139-03-TM-DV-P-TR indicates that the connector is designed to handle both signal-level and power-level connections within the same 78-position housing. This enables combined digital I/O and power delivery on a single connector strip, reducing PCB connector count and simplifying board-to-module wiring in industrial and computing designs.
Is TSM-139-03-TM-DV-P-TR compatible with standard automated pick-and-place and reflow soldering?
Yes. TSM-139-03-TM-DV-P-TR is supplied in tape-and-reel (TR) format with a surface-mount (TM) termination style, making it fully compatible with standard SMT automated assembly. The connector withstands reflow soldering temperatures up to 260°C, meeting J-STD-020 requirements for lead-free assembly in high-volume PCB manufacturing.
Which mating connector series from SAMTEC is compatible with TSM-139-03-TM-DV-P-TR?
TSM-139-03-TM-DV-P-TR belongs to SAMTEC's TSM terminal strip series and is designed to mate with corresponding SFM or SSW series socket strips sharing the 0.100 inch (2.54 mm) dual-row pitch. The mating system supports a typical contact normal force of at least 100 grams per pin for reliable low-resistance connections across the 78 positions.
How does the 0.100 inch pitch of TSM-139-03-TM-DV-P-TR compare to finer-pitch alternatives for high-density designs?
The 0.100 inch (2.54 mm) pitch of TSM-139-03-TM-DV-P-TR is the industry-standard grid, providing robust solder joint geometry and ease of manual rework compared to 0.050 inch (1.27 mm) or 0.8 mm pitch alternatives. While fine-pitch connectors offer greater density, the 0.100 inch pitch provides simpler PCB routing, lower tooling costs, and broader compatibility with existing 2.54 mm grid designs.
