FTMH-109-03-L-DH-K-TR

Headers, Male Pins Overview

The FTMH-109-03-L-DH-K-TR is a surface mount board-to-board connector from the Samtec FTMH series. It features 18 positions arranged in two rows with a 1.00 mm (0.039 inch) pitch. The header utilizes phosphor bronze contacts with gold plating on the mating interface and tin plating on the termination legs. Designed for right-angle installation, it has an insulation height of 3.18 mm (0.125 inch). The unit operates within a temperature range of -55°C to +125°C and carries UL 94 V-0 flammability ratings.

Headers, Male Pins Feature Summary

• Right-angle surface mount configuration for compact vertical board stacking
• Gold-plated square pin contacts ensure reliable signal transmission
• High insulation height accommodates diverse board thicknesses
• Lead-free solderable construction supports automated pick-and-place assembly

Headers, Male Pins Applications

• Board-to-board interconnections in high-density electronics
• Vertical stacking of printed circuit boards in compact modules
• Industrial control systems requiring robust surface mount headers
• Telecommunications equipment utilizing micro terminal strips

Headers, Male Pins Procurement Notes

Verify the specific suffix K-TR against official documentation to confirm tape-and-reel packaging and lead coplanarity specifications. Ensure the right-angle orientation matches the design intent. Cross-reference the insulation height of 3.18 mm with mechanical constraints. Confirm RoHS compliance status directly with the manufacturer before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a right-angle surface mount connection is required with a 1.00 mm pitch. The 18-position dual-row layout suits applications needing moderate I/O density in a small footprint. Consider the 3.18 mm insulation height for adequate clearance above the mating board. Verify that the phosphor bronze contact material meets the mechanical durability requirements of the intended cycle life.

Headers, Male Pins Part Context

This part belongs to the FTMH series of low-profile SMT micro terminal strips. The series offers various row counts, lengths, and mounting options. The FTMH-109 variant specifically denotes a 9-position per row configuration. The DH suffix indicates the right-angle body style, while the TR suffix specifies tape-and-reel packaging for automated manufacturing processes.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Samtec FTMH series parts with matching 1.00 mm pitch and 18-position count. Verify that alternative right-angle headers maintain the same 3.18 mm insulation height. Ensure contact plating and current ratings meet or exceed original specifications. Check for identical package dimensions to guarantee mechanical fit without PCB redesign.
