What are the key features of TSM-121-04-SM-DH-P-TR?

  • 42-position 4-row surface-mount terminal strip on 0.100-inch (2.54 mm) pitch for high pin-count interconnects
  • Side-mount (SM) dual-height (DH) design supports board-edge stacking and flexible height clearance options
  • Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly for volume production
  • Surface-mount termination eliminates through-hole drilling and simplifies PCB fabrication
  • Compatible with SAMTEC TSM mating connectors for reliable 4-row board-to-board signal routing

What is TSM-121-04-SM-DH-P-TR used for?

The TSM-121-04-SM-DH-P-TR is suited for complex board-to-board and board-to-module interconnect applications in FPGA development boards, industrial PLCs, and embedded single-board computers where 42-position, 4-row connectivity is needed. Its side-mount, dual-height design allows flexible stacking configurations across boards with varying standoff heights. The tape-and-reel format supports seamless integration into automated SMT production lines for both prototype and high-volume manufacturing.

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.
