Frequently Asked Questions
What is the pin count and pitch configuration of the TSM-128-04-SM-DH-P-TR?
The TSM-128-04-SM-DH-P-TR has 56 positions arranged in a dual-row format with 28 pins per row at 0.100 inch (2.54 mm) pitch, making it one of the higher pin-count options in the SAMTEC TSM surface mount terminal strip series.
Can the TSM-128-04-SM-DH-P-TR be used with standard reflow soldering in SMT production?
Yes. The SM (solder mount) termination and tape-and-reel packaging of the TSM-128-04-SM-DH-P-TR are compatible with standard reflow soldering at temperatures up to 260°C peak, supporting fully automated SMT assembly with pick-and-place equipment and common lead-free solder pastes.
How does the 56-position TSM-128 compare with lower pin-count TSM variants for board space efficiency?
Compared with 40-pin or 50-pin TSM variants, the 56-position TSM-128-04-SM-DH-P-TR consolidates more signal lines into a single 2.54 mm pitch dual-row connector, reducing the total connector count and saving PCB area while maintaining the same standard footprint grid for mating headers.
