Frequently Asked Questions
What position count and pitch does the TSM-129-03-SM-DH-A-K-TR support for backplane interconnect designs?
The TSM-129-03-SM-DH-A-K-TR provides 58 positions in a dual-row surface-mount configuration at 0.100" (2.54 mm) pitch. This standard pitch makes it directly compatible with SAMTEC TSW and TFM mating headers and works with all major SMT assembly machines, simplifying backplane and daughtercard design without custom tooling.
How does the dual-height (-DH) feature help engineers managing tall components near the TSM-129-03-SM-DH-A-K-TR?
The dual-height variant adds clearance between the mated connector bodies, which prevents mechanical interference with tall components such as electrolytic capacitors or inductors placed near the 58-position connector. This is particularly useful in dense 0.100" pitch PCB layouts where component heights can exceed standard board-to-board standoffs.
In what packaging format does the TSM-129-03-SM-DH-A-K-TR ship, and how does this benefit production efficiency?
The TSM-129-03-SM-DH-A-K-TR ships in tape-and-reel format as indicated by the -TR suffix. Tape-and-reel packaging enables automated pick-and-place SMT assembly at high throughput rates, with each reel containing hundreds of 58-position connectors, reducing manual handling and improving yield consistency in production runs.
Is the TSM-129-03-SM-DH-A-K-TR a suitable choice for RoHS-compliant manufacturing in global markets?
Yes, SAMTEC TSM series connectors including the TSM-129-03-SM-DH-A-K-TR are lead-free and RoHS compliant per EU Directive 2011/65/EU. The gold-plated contacts are compatible with lead-free solder reflow processes, making the 58-position dual-row strip suitable for global commercial and industrial electronics programs requiring full environmental compliance.
