Key Features
- 4-position dual-row horizontal SMT layout with 0.100" (2.54 mm) pitch, providing 8 total contacts for compact signal routing on densely populated PCBs
- Shrouded female socket housing with right-angle entry for side-access mating, reducing vertical clearance requirements in low-profile assemblies
- Surface-mount termination eliminates through-hole drilling, enabling faster automated PCB assembly and reducing fabrication costs
Applications
The TSM-104-03-FM-SH-A is a good fit for compact consumer electronics, embedded controllers, and industrial sensor boards where space-saving right-angle SMT connectors are needed for board-to-wire or board-to-board signal interfaces. Its 4-position shrouded female socket design is commonly used in UART, SPI, and I2C debugging headers, power distribution taps, and modular expansion slots on sub-boards and daughter cards.

Frequently Asked Questions
How many contacts does the TSM-104-03-FM-SH-A provide, and how are they arranged?
The TSM-104-03-FM-SH-A is a 4-position dual-row connector with 0.100" (2.54 mm) pitch, yielding 8 total contacts arranged in 2 rows of 4. The horizontal right-angle orientation means the mating cable exits parallel to the PCB surface, which is ideal for low-profile enclosures where vertical cable exits would exceed height clearance limits.
What board assembly process is the TSM-104-03-FM-SH-A designed for, and what are its PCB footprint advantages?
The TSM-104-03-FM-SH-A uses surface-mount termination pads, making it compatible with standard SMT reflow soldering processes. This eliminates through-hole drilling, reduces PCB layer constraints, and allows placement by pick-and-place machines, shortening assembly cycle time for production runs requiring consistent 0.100" (2.54 mm) pitch connector placement across multiple boards.
In which signal-level applications does the TSM-104-03-FM-SH-A excel compared to a through-hole alternative?
The TSM-104-03-FM-SH-A excels in low-power digital signal applications such as UART, SPI, and I2C interface headers operating below 250 mA per contact, where the SMT form factor reduces mechanical stress on the PCB compared to through-hole press-fit alternatives. It is particularly effective on thin multilayer boards (under 1.6 mm) where through-hole connectors could compromise layer integrity.
Which Samtec series would be a direct substitute if I need a vertical rather than horizontal mating direction?
If a vertical mating direction is preferred over the right-angle entry of the TSM-104-03-FM-SH-A, the Samtec TSM-104-03-FM-SH (without the -A suffix indicating horizontal) provides the same 4-position, 0.100" (2.54 mm) pitch dual-row layout in a vertical SMT configuration. Both share the same 8-contact female socket housing and shroud geometry, so the board footprint change is limited to the pad rotation.
