Frequently Asked Questions
What is the position count, row configuration, and pitch of TSM-121-04-SM-DH-P-TR?
The TSM-121-04-SM-DH-P-TR is a 42-position, 4-row surface-mount terminal strip using 0.100-inch (2.54 mm) pitch, with approximately 10 to 11 positions per row. This multi-row arrangement supports high-density parallel buses and mixed signal-power routing across FPGA expansion modules, industrial I/O boards, and embedded computing platforms.
How does the SM (side-mount) and DH (dual-height) design of TSM-121-04-SM-DH-P-TR affect board stacking clearance?
The side-mount (SM) feature positions the connector at the board edge, reducing the height profile above the PCB surface for compact enclosure fits. The dual-height (DH) option supports two mating connector heights, allowing engineers to set board-to-board standoff distances from approximately 4 mm to 8 mm depending on the chosen mating connector, giving flexibility for different PCB stacking configurations.
Is TSM-121-04-SM-DH-P-TR available in tape-and-reel for production and what lead times should buyers expect?
Yes, the TR suffix confirms the TSM-121-04-SM-DH-P-TR is supplied in tape-and-reel format compatible with standard automated SMT pick-and-place machines. SAMTEC typically ships standard TSM series connectors within 1 to 2 weeks, and authorized distributors carry inventory for small prototype quantities. For volume production of thousands of pieces, confirming availability 4 to 6 weeks ahead of build date is advisable.
