Overview
The M20-8760246P is a surface-mount pin header from the Harwin M20 series, featuring a 4-position configuration with a 2.54mm pitch. It utilizes square brass contacts with gold plating for mating and tin plating for the tail, housed in black PA6T insulation rated UL94 V-0. The connector supports a current rating of 3A per contact at 250V, operating within -40°C to 105°C. It offers a mating contact length of 5.80mm and compatible stacking heights of 11.53mm, 12.23mm, 12.63mm, or 18.13mm.
Feature Summary
- Surface mount design with cuttable format for flexible PCB integration
- Gold-plated square contacts ensure reliable signal transmission
- PA6T insulation provides high thermal stability and flammability resistance
Applications
- Board-to-board interconnections
- Cable-to-board connections
- Compact electronic device interfaces
Procurement Notes
Verify the specific suffix 'P' against official datasheets to confirm packaging details, as distributors may list varying pack quantities. Ensure the component status is active before ordering, as lifecycle changes can occur. Cross-reference the 4-position count with schematic requirements to avoid mismatched inventory acquisition.
Selection Notes
Select this model for applications requiring low-profile surface mounting with precise 2.54mm spacing. The gold-plated contacts are suitable for sensitive signals, while the cuttable feature allows for custom row lengths. Verify that the required stacking height matches one of the four supported options for proper assembly clearance.
Part Context
This component belongs to the M20 series, designed for high-density interconnects. It complements socket assemblies like the M20-783xxxxx series. The 4-position variant serves as a compact solution for minimal footprint designs where standard headers are too large.
Replacement Considerations
Compatible substitutes include other 4-position SMD headers with 2.54mm pitch and similar electrical ratings. Verify mechanical compatibility with mating sockets such as the M20-7830246 series.
