What are the key features of TSM-109-04-SS-DH-P-TR?
- 18-position dual-row layout at 0.100 inch (2.54 mm) pitch providing industry-standard spacing for easy PCB routing and compatible mating header selection
- Dual-height (DH) profile enables board-to-board stacking at precise standoff heights, accommodating component clearances in multi-board assemblies
- Tape and reel (TR) packaging and alignment posts (P option) support automated SMT pick-and-place assembly with correct orientation and reduced placement errors
What is TSM-109-04-SS-DH-P-TR used for?
The TSM-109-04-SS-DH-P-TR is designed for surface-mount board-to-board and wire-to-board interconnect applications in industrial control, embedded computing, and consumer electronics where an 18-position, 0.100 inch pitch interface is needed. Its dual-height configuration accommodates varying PCB spacer requirements in stacked module assemblies, such as processor boards mated to I/O expansion cards. The tape-and-reel format enables efficient high-volume automated assembly in production environments.

Frequently Asked Questions
What does the dual-height (DH) designation mean for TSM-109-04-SS-DH-P-TR in board stacking applications?
The dual-height (DH) designation means the TSM-109-04-SS-DH-P-TR is designed with two distinct body height levels, typically separated by several millimeters, to provide a defined standoff between two mated PCBs. This allows engineers to stack boards with controlled spacing to accommodate components mounted on one or both board surfaces, commonly needed in embedded computing modules where clearance above the motherboard must be at least 4 mm or more.
How does the 0.100 inch pitch of the TSM-109-04-SS-DH-P-TR simplify connector selection for existing designs?
The 0.100 inch (2.54 mm) pitch is the most widely used standard spacing in through-hole and SMT connectors, making the TSM-109-04-SS-DH-P-TR compatible with a broad range of SAMTEC and third-party mating headers without requiring custom PCB layouts. Engineers can replace through-hole 18-position connectors with this SMT version without redesigning the overall pin-field footprint, saving re-layout time and reducing design iteration cycles.
For a high-volume SMT line, what packaging and placement advantages does the TSM-109-04-SS-DH-P-TR offer?
Supplied in tape and reel (TR) format, the TSM-109-04-SS-DH-P-TR is compatible with standard SMT pick-and-place machines that use reel feeders, enabling placement rates of hundreds of parts per hour. The alignment posts (P option) press into the PCB to hold the connector at correct height and angle during the reflow soldering process at up to 260°C, preventing tombstoning across the 18-position footprint and reducing rework costs in production.
