MTSW-120-21-G-D-800

Headers, Male Pins Overview

The MTSW-120-21-G-D-800 is a variable height PCB header strip from Samtec's Flex Stack series. It features a 40-position, double-row configuration with a 2.54 mm (0.1 in) pin spacing. Designed for through-hole mounting, the connector utilizes phosphor bronze contacts with gold plating over nickel. The mating post length is specified as 3.149 mm (0.124 in), while the termination post length is 2.032 mm (0.080 in). The housing is constructed from black polyester and meets UL 94 V-0 flammability standards. It operates within a temperature range of -55°C to +125°C.

Headers, Male Pins Feature Summary

• Variable height design accommodates diverse board stacking requirements
• Gold-plated phosphor bronze contacts ensure reliable signal integrity
• Flexible tail construction allows for easy insertion into plated-through holes

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board connections
• High-density electronic assemblies

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm exact physical dimensions and material specifications. Ensure that the selected variant matches the required mating height and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and compliance with regional regulatory standards such as RoHS.

Headers, Male Pins Selection Notes

Select this component when flexible insertion into existing PCB layouts is required without custom tooling. The variable height feature simplifies assembly processes by allowing manual adjustment during installation. Consider the mechanical stress on the PCB pads due to the flexible tails and ensure adequate board support. Evaluate the contact material and plating thickness if the environment involves high corrosion or frequent mating cycles.

Headers, Male Pins Part Context

This part belongs to the MTSW series of variable height PCB headers. It is designed to mate with various Samtec socket strips and other compatible male connectors. The series offers a cost-effective solution for prototyping and low-volume production where standard fixed-height headers may not fit the mechanical constraints of the enclosure or assembly process.

Headers, Male Pins Replacement Considerations

Direct replacements must match the 40-position count, 2.54 mm pitch, and double-row configuration. Verify that alternative suppliers offer comparable gold plating thickness and phosphor bronze contact materials. Ensure the replacement part supports the same operating temperature range and current carrying capacity. Check mechanical compatibility with mating sockets to prevent connection failures.
