M20-9980445

Headers, Male Pins Overview

The M20-9980445 is a vertical pin header from the Harwin M20 series, featuring an unshrouded design with two rows and eight contacts. It utilizes a 2.54 mm pitch spacing for board-to-board or wire-to-board connections. The connector employs gold-plated phosphor bronze contacts housed in black UL94 V-0 polyamide (nylon) 6T insulation. Rated for 3A current, it supports a temperature range of -40°C to 105°C. The component uses through-hole termination with a 3mm tail pin length and a 6.1mm mating pin height.

Headers, Male Pins Feature Summary

• Vertical through-hole mounting configuration for direct PCB integration
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Unshrouded dual-row layout facilitates flexible cable routing
• Polyamide 6T housing provides high thermal stability and flame resistance

Headers, Male Pins Applications

• Board-to-board interconnections in compact electronic assemblies
• Wire-to-board connections requiring robust mechanical retention
• Industrial control systems operating within specified temperature ranges
• Consumer electronics utilizing standard 2.54 mm pitch interfaces

Headers, Male Pins Procurement Notes

Verify the specific contact plating specification against the official datasheet, as variations exist within the M20 series regarding gold versus tin finishes. Confirm that the 6.1mm mating height aligns with the target assembly stack-up requirements. Ensure the polyamide 6T material grade meets the thermal endurance needs of the final application environment before procurement.

Headers, Male Pins Selection Notes

Select this component when a vertical, unshrouded header is required for high-density layouts. The 2.54 mm pitch offers compatibility with standard ribbon cables and IDC connectors. Consider the 3A current rating for power distribution lines. Verify that the through-hole soldering process accommodates the 3mm tail length without excessive board warping during reflow.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, designed for general-purpose interconnect solutions. The series offers various row counts and contact configurations to suit diverse density requirements. The M20-9980445 specifically addresses applications needing a compact 8-contact vertical interface with durable metallic contacts and thermally stable insulation materials for long-term reliability.

Headers, Male Pins Replacement Considerations

Direct substitutes include other M20 series headers with identical 2.54 mm pitch and 8-pin count, such as M20-9980446, provided the contact plating matches the system requirements. Cross-series replacements require verification of mating dimensions, current ratings, and thermal characteristics to ensure functional equivalence.
