MTMM-120-08-S-S-340

Headers, Male Pins Overview

The Samtec MTMM-120-08-S-S-340 is a single-row variable post height header strip with a 2.00 mm pitch and 20 positions. It utilizes phosphor bronze contacts plated with 30 microinches of selective gold on the contact area and matte tin on the tail, designed for through-hole termination. The connector features a straight mounting angle and an unlatched configuration housed in black liquid crystal polymer (LCP). It operates within a temperature range of -55°C to +125°C and meets UL 94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Features a flex stack design that allows for modified post heights and body positioning in precise increments to accommodate varying board stacking requirements.
• Utilizes a .020 inch square post contact system to ensure reliable mating performance in high-density applications.

Headers, Male Pins Applications

• Board stacking interconnects requiring specific height adjustments
• Embedded communication systems needing flexible post configurations
• General-purpose PCB headers where custom terminal lengths are required

Headers, Male Pins Procurement Notes

Verify the exact suffix codes against official Samtec documentation to confirm plating specifications and lead style. Ensure the selected part number matches the required pin count and row configuration for your specific assembly needs. Cross-reference RoHS compliance status directly with the manufacturer's current material declarations before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a single-row through-hole header with customizable post height is necessary. The 2.00 mm pitch supports moderate density connections while the flex stack capability accommodates mechanical tolerances between stacked boards. Consider the LCP housing material for its thermal stability and the gold-tin plating combination for balanced conductivity and solderability.

Headers, Male Pins Part Context

This part belongs to the MTMM series of variable post height header strips from Samtec. The series provides extensive flexibility in pin counts, terminal lengths, and row options up to four rows. The MTMM designation indicates a standard header strip format designed for versatile integration into various electronic assemblies requiring precise vertical spacing control.

Headers, Male Pins Replacement Considerations

Direct substitutes include other MTMM series variants with matching 2.00 mm pitch and single-row configuration, such as MTMM-120-08-G-S-340 or MTMM-120-08-L-S-340, provided the plating differences are acceptable. Verify that any replacement maintains the same physical dimensions and electrical ratings to ensure compatibility with existing footprints and mating connectors.
