MTLW-120-06-F-S-125

Headers, Male Pins Overview

The Samtec MTLW-120-06-F-S-125 is a single-row header connector featuring 20 positions with a 2.54 mm (0.1 in) pitch. Designed for through-hole mounting, it utilizes solder pin termination and straight installation angles. The contacts are male pins made of phosphor bronze with gold plating, rated for 5.2 A current. The housing is constructed from black liquid crystal polymer (LCP) with UL 94 V-0 flammability rating. It operates within a temperature range of -55°C to +125°C and has an unlatched closure type.

Headers, Male Pins Feature Summary

• Features a flexible stacking design allowing variable post height adjustment in 0.005 inch increments
• Utilizes .025 inch square contact terminals for improved mating stability
• Supports vertical board-to-board or cable connections via through-hole soldering

Headers, Male Pins Applications

• Board-to-board interconnections requiring variable height clearance
• Cable-to-board connections in compact electronic assemblies
• High-density circuit board interfaces needing reliable signal transmission

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm terminal length and contact material variations. Ensure the selected variant matches the required operating temperature range and current rating for the target application. Confirm RoHS compliance status and lead times directly with authorized distributors prior to finalizing procurement plans.

Headers, Male Pins Selection Notes

Select this component when variable post height flexibility is required for precise board spacing. The single-row configuration suits applications with limited lateral space. Verify that the 2.54 mm pitch aligns with existing PCB footprint designs. Consider the gold-plated phosphor bronze contacts for corrosion resistance and low contact impedance needs.

Headers, Male Pins Part Context

This part belongs to the Flex Stack MTLW series, characterized by its low-profile design and variable post height capabilities. The series is engineered for high-reliability interconnects in demanding environments. The specific model denotes a 20-position single-row header with fixed terminal lengths defined by the ordering code.

Headers, Male Pins Replacement Considerations

Direct substitutes include MTLW-120-06-G-S-140 and MTLW-120-06-G-S-141, which share identical positional and pitch specifications but differ in terminal length and contact material composition.
