MTLW-111-09-G-D-308

Headers, Male Pins Overview

The MTLW-111-09-G-D-308 is a .100" (2.54mm) pitch low profile variable post height terminal strip manufactured by Samtec Inc. It features a double row configuration with 18 positions, designed for through-hole mounting. The connector utilizes phosphor bronze contacts with gold plating and a liquid crystal polymer (LCP) insulator rated UL94 V-0. Electrical specifications include a current rating of 5.2A per contact and an operating temperature range of -55°C to +125°C. Mechanical dimensions specify a mating contact length of 7.366 mm (0.29 in), a termination contact length of 9.654 mm (0.38 in), and an overall contact length of 11.020 mm (0.434 in).

Headers, Male Pins Feature Summary

• Features an elastic stacking design that allows for variable post heights in .005" increments.
• Utilizes .025" square posts for reliable board-to-board or cable connections.
• Constructed with LCP insulation material offering high thermal stability.

Headers, Male Pins Applications

• Board-to-board interconnects requiring flexible stacking heights.
• High-density electronic assemblies needing precise vertical spacing.
• Industrial control systems operating within extreme temperature ranges.

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm exact pin count, plating thickness, and termination style. Ensure compatibility with mating connectors regarding pitch and height variations. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when variable post height flexibility is required within a standard .100" pitch system. The gold-plated phosphor bronze contacts provide superior conductivity and corrosion resistance compared to tin variants. Consider the total height dimensions to ensure adequate clearance for surrounding components on the PCB layout.

Headers, Male Pins Part Context

This part belongs to the Flex Stack MTLW series, which provides low-profile solutions for space-constrained designs. The series is characterized by its ability to accommodate varying board stack heights without custom manufacturing, utilizing standardized variable post lengths. It serves as a robust alternative to fixed-height headers in complex multi-layer PCB architectures.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include MTLW-111-09-T-D-308 (tin plating) or MTLW-111-09-G-S-308 (single row). Verify that mating connectors support the .025" square post interface and compatible height tolerances before substitution.
