MTLW-120-22-G-D-285

Headers, Male Pins Overview

The Samtec MTLW-120-22-G-D-285 is a .100 inch (2.54 mm) pitch low profile variable post height terminal strip from the Flex Stack series. It features a dual row configuration with 40 positions, designed for through-hole mounting in a straight orientation. The connector utilizes phosphor bronze contacts with gold plating to ensure reliable signal transmission. Rated for 5.2 A current and operating within a temperature range of -55°C to +125°C, it employs an unlatched locking mechanism. The housing is constructed from black liquid crystal polymer (LCP) with a UL 94 V-0 flammability rating.

Headers, Male Pins Feature Summary

• Variable post height design accommodates diverse board-to-board spacing requirements
• Low profile form factor optimizes vertical clearance in compact assemblies
• Gold-plated phosphor bronze contacts provide durable electrical connectivity

Headers, Male Pins Applications

• Board-to-board interconnections
• Embedded communication systems
• General electronic circuit integration

Headers, Male Pins Procurement Notes

Verify the specific mating post length of 7.188 mm (0.283 in) against your mechanical stack-up requirements before procurement. Confirm that the through-hole solder pin termination matches your PCB fabrication capabilities. Ensure the LCP housing material meets your environmental resistance standards. Cross-reference the 40-position dual-row layout with your schematic netlist to prevent pinout mismatches during assembly.

Headers, Male Pins Selection Notes

Select this component when a fixed-height header is insufficient for your assembly tolerance. The variable post feature allows for adjustment during manufacturing or repair. Compare the 2.54 mm pitch against denser alternatives if space is constrained. Consider the 5.2 A current rating against your total load requirements. Verify compatibility with mating sockets from the same Flex Stack family to ensure proper engagement.

Headers, Male Pins Part Context

This part belongs to the MTLW series of low-profile terminal strips manufactured by Samtec. It shares the standard .100 inch grid with other headers but distinguishes itself through adjustable post heights. The Flex Stack branding indicates its role in flexible stacking solutions. It complements socket strips like the SSW series for complete interconnect systems.

Headers, Male Pins Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Variants within the MTLW series may differ in post length or position count. Direct replacement requires matching the 2.54 mm pitch, 40-position dual-row layout, and through-hole termination style.
