What are the key features of TSM-123-03-S-DH-A-K-TR?

  • 46-position dual-row layout on 0.100 inch (2.54 mm) pitch with single-beam contacts for reliable 46-pin board-to-board signal routing
  • Surface-mount tape-and-reel packaging supports automated pick-and-place SMT assembly for high-volume industrial and computing production
  • SAMTEC TSM series high-reliability terminal strip construction ensures consistent contact resistance across repeated mating cycles in demanding environments

What is TSM-123-03-S-DH-A-K-TR used for?

TSM-123-03-S-DH-A-K-TR is intended for board-to-board and mezzanine card signal interconnects in embedded computing modules, network equipment, and industrial control systems requiring 46 parallel signal lines at 0.100" pitch. The single-beam dual-row configuration mates with compatible SAMTEC SFM-123 socket strips, enabling reliable data bus and I/O signal routing between daughter cards and backplane boards. Tape-and-reel packaging integrates the connector into automated SMT reflow assembly processes for consistent placement in high-volume manufacturing.

Frequently Asked Questions

What distinguishes TSM-123-03-S-DH-A-K-TR from TSM-123-02-SM-DH-A-K-TR in terms of contact design?

TSM-123-03-S-DH-A-K-TR uses a single-beam (S) contact design across its 46 positions on a 0.100 inch (2.54 mm) pitch dual-row layout, while the TSM-123-02 variant uses a different contact beam configuration. Single-beam contacts typically provide a defined normal force against the mating socket, maintaining reliable electrical connection across the 46-pin interface in vibration-prone industrial and computing environments.

How many signal lines does TSM-123-03-S-DH-A-K-TR support and how does it mount on a PCB?

TSM-123-03-S-DH-A-K-TR provides 46 signal positions in a dual-row configuration with 23 contacts per row on a 0.100 inch (2.54 mm) pitch. It mounts as a surface-mount component using SMT reflow soldering, with tape-and-reel (TR) packaging for automated pick-and-place placement on standard SMT assembly lines.

Which socket family mates with TSM-123-03-S-DH-A-K-TR for a board-to-board stack application?

TSM-123-03-S-DH-A-K-TR mates with SAMTEC SFM-123 series dual-row socket strips designed for 0.100 inch (2.54 mm) pitch board-to-board stacking. The SFM-123 socket accepts all 46 contacts and is available in various stack heights to accommodate different board separation distances in mezzanine module and daughter-card assembly designs.

For a compact embedded board design, how does the 0.100 inch pitch of TSM-123-03-S-DH-A-K-TR compare to finer-pitch alternatives for 46 signals?

At 0.100 inch (2.54 mm) pitch with 23 contacts per row, TSM-123-03-S-DH-A-K-TR occupies approximately 58 mm in board length for 46 pins. Choosing a 0.050 inch (1.27 mm) pitch alternative would halve this to about 29 mm, but the 0.100 inch pitch provides easier PCB routing and broader socket availability. For designs where 60 mm is acceptable, the standard 2.54 mm pitch simplifies layout and sourcing.
