What are the key features of TSM-121-05-F-SH-A?
- 42-position dual-row SMT configuration at 0.100 inch (2.54 mm) standard pitch for broad PCB compatibility and easy routing
- Horizontal single-row SMT termination reduces component height and suits low-profile board assemblies with tight vertical clearance
- Surface-mount termination eliminates through-hole drilling requirements, streamlining PCB fabrication and automated assembly processes
What is TSM-121-05-F-SH-A used for?
The TSM-121-05-F-SH-A is a versatile dual-row SMT terminal strip suited for industrial control boards, embedded computing modules, and communication equipment where a 42-position 2.54 mm pitch surface-mount connector simplifies PCB assembly. Its horizontal orientation makes it especially useful in low-profile or slim form-factor designs that cannot accommodate vertical or through-hole connectors. This part is widely used in test and measurement instruments, backplane sub-assemblies, and PCB panel expansion interfaces.

Frequently Asked Questions
How many total positions does the TSM-121-05-F-SH-A provide in its dual-row layout?
The TSM-121-05-F-SH-A is a dual-row terminal strip with 21 positions per row, providing 42 total contacts at a 0.100 inch (2.54 mm) pitch in a surface-mount horizontal footprint. This contact count supports moderate bus widths and multi-signal interfaces in a single SMT connector suitable for industrial and embedded PCBs.
What advantage does horizontal SMT termination offer for the TSM-121-05-F-SH-A compared to vertical SMT configurations?
Horizontal SMT termination on the TSM-121-05-F-SH-A positions the connector body parallel to the PCB surface, reducing vertical component height significantly compared to vertical SMT styles. This makes the connector ideal for slim enclosures, card-edge backplanes, and stacked board assemblies with inter-board clearance of only a few millimeters, without sacrificing the 42-pin 2.54 mm pitch connectivity.
Can the TSM-121-05-F-SH-A simplify PCB manufacturing compared to a through-hole dual-row header at the same pitch?
Yes, replacing a through-hole dual-row header with the TSM-121-05-F-SH-A eliminates the need to drill 42 plated through-holes, reducing PCB fabrication cost and routing congestion on inner layers. The surface-mount pads can be reflowed in a standard SMT oven pass alongside other components, enabling a fully automated assembly process without a separate wave-solder or hand-solder step for the connector.
