MTSW-112-09-T-S-455

Headers, Male Pins Overview

Samtec Inc. MTSW-112-09-T-S-455 is a variable height PCB header strip from the Flex Stack MTSW series, featuring a 0.100" (2.54mm) pitch and 12 positions in a single row. It utilizes a .025" (.635 mm) square post contact system with gold flash termination for through-hole mounting. The connector supports vertical or right-angle orientations and offers modified post heights in .005" increments. Constructed with phosphor bronze contacts and polyester insulation rated UL 94 V-0, it operates within a temperature range of -55°C to +125°C.

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 robust mechanical stability and reliable mating
• Through-hole termination ensures secure board attachment for standard manufacturing processes

Headers, Male Pins Applications

• Board-to-board interconnections requiring specific stack-up heights
• Cable-to-board connections with variable clearance needs
• General electronic assemblies utilizing standard 0.100 inch spacing

Headers, Male Pins Procurement Notes

Verify the exact suffix code against the official Samtec catalog to confirm the specific terminal length variant, as the MTSW series relies on numerical suffixes to define physical dimensions. Ensure the selected part matches the required operating temperature range and insulation material specifications for your application environment. Cross-reference the RoHS compliance status and moisture sensitivity level with current regulatory requirements before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when standard header lengths do not accommodate specific board-to-board spacing requirements. The variable height capability allows designers to adjust post lengths without custom tooling. Confirm that the single-row configuration fits the available footprint and that the through-hole termination method aligns with the assembly process capabilities. Evaluate the thermal performance against the specified operating temperature limits.

Headers, Male Pins Part Context

The MTSW series represents a variation of the classic TSW header strip, offering enhanced flexibility through adjustable pin lengths. This specific model belongs to the Flex Stack family, designed to simplify assembly by eliminating the need for multiple unique part numbers for different heights. It maintains compatibility with standard mating connectors while providing customizable physical dimensions.

Headers, Male Pins Replacement Considerations

Direct substitutes include other MTSW-112 variants with identical pitch and position counts but different terminal lengths. Verify that any replacement maintains the same square post diameter and through-hole termination style to ensure mechanical fit.
