MTSW-109-12-T-S-540-RE

Headers, Male Pins Overview

Samtec Inc. MTSW-109-12-T-S-540-RE is a variable height PCB header strip from the Flex Stack MTSW series, featuring a 0.100 inch (2.54 mm) pitch. This single-row connector utilizes through-hole termination with a right-angle orientation and includes a reel option for automated assembly. The contact system employs .025 inch square posts, allowing for modified post heights and body positions in 0.005 inch increments to accommodate diverse application requirements.

Headers, Male Pins Feature Summary

• Flex Stack design enables precise modification of post height and body position in small increments
• Square post terminal system provides reliable mechanical stability and consistent mating performance
• Reel packaging configuration supports efficient automated surface mount or through-hole processing

Headers, Male Pins Applications

• Board-to-board interconnections requiring specific stack height adjustments
• Wire-to-board connections where flexible positioning is necessary
• Automated manufacturing environments utilizing reel-fed assembly equipment

Headers, Male Pins Procurement Notes

Verify the exact pin count and terminal length suffix against the official Samtec datasheet to ensure compatibility with the target PCB footprint. Confirm that the reel packaging specification matches the requirements of the automated placement machinery used in the production line. Cross-reference the insulation material ratings with the operating environment conditions.

Headers, Male Pins Selection Notes

Select this component when standard fixed-height headers cannot meet specific spatial constraints due to varying board thicknesses or component clearances. The adjustable nature of the Flex Stack system allows designers to optimize vertical space without custom tooling. Ensure the chosen terminal length aligns with the required engagement depth for the mating connector interface.

Headers, Male Pins Part Context

The MTSW series represents a variation on the classic TSW header strip, offering a wide range of overall pin lengths to satisfy virtually any application. It maintains the standard 0.100 inch pitch while providing enhanced flexibility through its unique terminal design. This series is widely used in industrial and commercial electronics where reliable connectivity and spatial adaptability are critical.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include MTSW-109-12-T-S-540 without the RE suffix for bulk packaging, or variants with different terminal lengths such as MTSW-109-12-T-S-740. Verify that alternative part numbers maintain the same single-row configuration and right-angle orientation to preserve mechanical fit.
