M20-9993545

Headers, Male Pins Overview

The Harwin M20-9993545 is a vertical pin header from the M20 series, featuring a 2.54mm pitch and 35 positions. It utilizes gold-plated brass contacts with a 3A current rating per contact. The connector employs a through-hole solder termination and is constructed from black PA6T insulation rated UL94 V-0. Designed for board-to-board or cable applications, it operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Vertical pin header design with cuttable strip capability
• Gold-plated square brass contacts for reliable signal transmission
• High-temperature resistant PA6T insulation material

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board connections
• General electronic circuit assembly

Headers, Male Pins Procurement Notes

Verify the specific suffix '45' confirms the gold plating finish, as other suffixes may indicate tin plating. Confirm the 35-position count matches the design requirement. Ensure the vertical orientation and through-hole mounting style are compatible with the PCB layout constraints.

Headers, Male Pins Selection Notes

Select this component when a high-density, vertically oriented connection is required. The gold plating offers superior corrosion resistance compared to tin alternatives. The PA6T housing provides enhanced thermal stability for high-temperature soldering processes and operation environments.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, which standardizes on a 2.54mm (0.1 inch) pitch. The series offers various row counts, plating options, and orientations to support diverse connectivity needs in compact electronic assemblies.

Headers, Male Pins Replacement Considerations

M20-9993546 serves as a direct substitute if tin plating is acceptable instead of gold. Other M20 series headers with identical pitch and position count may be considered if mechanical variations are permissible.
