Key Features
- 4-position dual-row layout on 0.100 inch (2.54 mm) pitch matching standard IDC and discrete cable assemblies
- Gold-plated mating contacts ensuring low contact resistance and corrosion resistance over thousands of mating cycles
- SMT surface-mount design with peg board-mounting option for accurate placement and reflow soldering
- Horizontal single-row orientation keeping the connector profile low for space-constrained PCB layouts
- Male rectangular contact pattern compatible with SAMTEC TSS and industry-standard 0.1-inch female housings
Applications
The TSM-104-02-SM-SH-A is used in embedded control boards, sensor interface modules, and test fixture panels where a low-profile SMT 0.100 inch pitch header provides a reliable 4-pin wire-to-board connection without through-hole drilling. Its gold-plated contacts and SMD footprint make it a strong choice for high-cycle debug or programming interfaces on production PCBs, such as SWD or UART ports accessed during in-circuit testing. The peg registration feature also benefits automated pick-and-place assembly lines where connector placement accuracy is critical for subsequent press-fit or cable mating operations.

Frequently Asked Questions
What contact finish does TSM-104-02-SM-SH-A use, and how does gold plating affect connector longevity in cycling applications?
The mating contacts of TSM-104-02-SM-SH-A are gold-plated, while the PCB termination tails use tin over nickel. Gold mating surfaces maintain contact resistance below 20 mΩ even after hundreds to thousands of insertion cycles, making them suitable for debug headers and in-circuit test points that are mated repeatedly during production. Tin terminations bond reliably to standard SAC305 solder paste during reflow at 250°C peak.
How does the peg board-mounting feature of TSM-104-02-SM-SH-A benefit high-volume PCB assembly?
The PEG board-mounting option adds plastic registration pegs to the TSM-104-02-SM-SH-A housing that press into corresponding PCB holes, holding the connector in position during reflow without adhesive or staking. This prevents the 0.4 × 0.12 inch connector from shifting during conveyor reflow, eliminating solder-joint bridging caused by misalignment on 0.100 inch pitch pads and reducing manual rework in high-volume SMT production lines.
For a 4-pin SWD debug port on a new microcontroller board, why choose TSM-104-02-SM-SH-A over a through-hole header?
SMT assembly of the TSM-104-02-SM-SH-A avoids drilling 4 through-holes that consume routing space on inner copper layers, which matters on dense 4-layer boards with tight via budgets. The connector's horizontal profile also keeps the 4-pin SWD port flush with the PCB surface, enabling low-profile enclosures. Once the product ships, the gold-plated contacts ensure reliable contact with standard 1.27 mm or 2.54 mm pitch debug probe tips over dozens of firmware update cycles.
What mating connectors are compatible with TSM-104-02-SM-SH-A for assembling a cable harness?
The TSM-104-02-SM-SH-A male header is designed to mate with SAMTEC TSS-104-xx-x-D female sockets or industry-standard 0.100 inch pitch crimp housings such as Molex KK 2.54 mm and JST VH 2.54 mm families. Dual-row 4-pin IDC connectors with 0.100 inch (2.54 mm) pitch also mate directly, supporting flat ribbon cables up to 4 conductors for simple board-to-wire harness assemblies.
