TSM-124-04-T-DH-A-K-TR SAMTEC Connector (Other) In Stock

SAMTEC TSM-124-04-T-DH-A-K-TR is a 48-position dual-row surface-mount terminal strip with 0.100" (2.54 mm) pitch and dual-height (DH) option for elevated mating clearance. Kinked (K) tail termination provides solder joint retention during reflow, and tape-and-reel packaging enables automated PCB assembly. Compatible with SAMTEC's SFM and SSQ socket series for robust board-to-board interconnects.

What are the key features of TSM-124-04-T-DH-A-K-TR?

  • 48-position dual-row 0.100" (2.54 mm) pitch surface-mount header providing 24 contacts per row for standard-density board-to-board interconnects
  • Dual-height (DH) mating post option creating additional clearance above the PCB surface to accommodate taller components on the mating board
  • Kinked (K) tail termination anchoring the 48-pin connector body to the PCB during 260°C reflow to prevent positional shift before solder solidification
  • Tape-and-reel (TR) packaging enabling high-speed pick-and-place automated assembly on standard SMT production lines

What is TSM-124-04-T-DH-A-K-TR used for?

The TSM-124-04-T-DH-A-K-TR is used in Arduino shield interconnects, industrial expansion backplanes, and PCB stacking assemblies where a standard 0.100" pitch 48-pin dual-row SMT header is required. Its dual-height post ensures sufficient component clearance between stacked boards, making it suitable for development platforms, SBC (Single Board Computer) expansion, and modular industrial I/O systems. Engineers deploy the kinked-tail variant in high-volume production environments where soldering consistency across all 48 pins is critical.

Frequently Asked Questions

How does the dual-height (DH) option in TSM-124-04-T-DH-A-K-TR differ from a standard mating height header?

The DH (dual-height) option provides a taller post above the PCB surface than the standard single-height TSM variant, typically adding 2 mm to 4 mm of additional board clearance. This extra height accommodates tall SMT capacitors or heat sinks on the mating board in 48-pin 0.100" pitch stacked assemblies, preventing interference between board surfaces.

Can the TSM-124-04-T-DH-A-K-TR be soldered using standard SMT reflow profiles?

Yes, the surface-mount termination and kinked (K) tail are designed for standard SMT reflow at temperatures up to 260°C per IPC/JEDEC J-STD-020. The kinked tail provides mechanical stabilization of the 48-pin connector body during the reflow process, ensuring all 0.100" pitch solder joints are formed correctly without connector movement.

Which SAMTEC socket connector is the recommended mating partner for the TSM-124-04-T-DH-A-K-TR?

SAMTEC's SSQ or SFM series sockets with matching 0.100" (2.54 mm) pitch and 48-position dual-row configuration are the primary mating options. The SSQ series offers a cost-effective alternative while the SFM high-reliability series supports 1000+ mating cycles with gold-plated contacts rated below 20 mΩ contact resistance for more demanding applications.

How does the 0.100" pitch of the TSM-124-04-T-DH-A-K-TR compare to SAMTEC's 0.050" pitch SFM series for the same 48-position requirement?

At 0.100" (2.54 mm) pitch the TSM-124 body is approximately 2× longer than a 0.050" pitch SFM-124 carrying the same 48 signals, trading off board space for greater mechanical robustness and compatibility with standard prototyping tooling. The wider 0.100" pitch also supports higher contact current ratings (typically 1 A to 3 A per contact) versus the finer 0.050" pitch rated around 1 A per contact.
