MTSW-120-22-T-S-440

Headers, Male Pins Overview

The MTSW-120-22-T-S-440 is a variable height PCB header strip manufactured by Samtec Inc. It features 20 positions arranged in a single row with a 2.54 mm (0.100 inch) contact spacing. The connector utilizes male pin contacts made of phosphor bronze, finished with tin plating. Designed for through-hole mounting, it offers a straight installation style and an unlatched locking mechanism. The housing is constructed from black polyester material rated UL 94 V-0 for flammability.

Headers, Male Pins Feature Summary

• Variable post height design accommodates diverse board stacking requirements
• Tin-plated phosphor bronze contacts ensure reliable electrical connectivity
• Single-row configuration provides compact board-to-board or cable interface solutions

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable to board connections
• General purpose electronic assemblies

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix matches the required terminal length and orientation. Confirm that the tin plating specification aligns with environmental compliance requirements such as RoHS. Ensure the through-hole mounting style is compatible with the target PCB fabrication capabilities. Cross-reference the single-row layout against available mating connectors within the Flex Stack family.

Headers, Male Pins Selection Notes

Select this component when a standard 2.54 mm pitch header is needed for low-cost applications. The tin finish is suitable for general use but may require consideration for high-cycle mating scenarios compared to gold options. The variable height feature allows for flexibility in assembly tolerances without custom tooling. Evaluate thermal limits against the specified operating temperature range during design.

Headers, Male Pins Part Context

This part belongs to the Flex Stack MTSW series of variable height PCB headers. The series is characterized by its ability to provide multiple mating lengths from a single header body. It serves as a fundamental interconnect solution for consumer electronics and industrial equipment requiring robust mechanical retention and simple solder termination.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Samtec MTSW variants with identical pitch and row count but different terminal lengths or plating finishes. Verify that any alternative maintains the same 2.54 mm spacing and single-row architecture to ensure PCB footprint compatibility.
