M20-7851146

Overview

The Harwin M20-7851146 is a dual in-line (DIL) socket assembly from the M20 series, designed for board-to-board applications. It features 11 positions per row with a total of 22 contacts arranged in two rows. The connector utilizes a 2.54 mm pitch and employs bottom entry termination for secure PCB mounting. The housing is constructed from high-temperature thermoplastic material rated UL94V-0, ensuring stability under thermal stress. Contacts are plated with tin to provide reliable electrical conductivity and corrosion resistance.

Feature Summary

• Dual in-line configuration with bottom entry termination for robust PCB integration
• High-temperature resistant housing material suitable for standard reflow processes
• Tin-plated contacts ensure durable electrical connections

Applications

• Board-to-board interconnections
• Industrial control systems
• Consumer electronics assemblies

Procurement Notes

Verify component status as this part may be discontinued or subject to limited availability. Confirm RoHS compliance details through official datasheets before procurement. Ensure compatibility with mating pin headers regarding pitch and contact geometry. Review end-of-life notifications for supply chain planning purposes.

Selection Notes

Select this model for applications requiring dual-row connectivity with a 2.54 mm spacing. Suitable for designs needing bottom-entry sockets to save vertical space. Consider the M20 series characteristics for general industrial use where reliability and temperature resistance are prioritized over high-speed signal integrity.

Part Context

Part of the Harwin M20 series, which offers compact PCB socket solutions. The series supports various position counts and row configurations. Designed for through-hole mounting with specific focus on density and height constraints in modern electronic assemblies.

Replacement Considerations

Check for direct substitutes within the M20 family such as M20-7851142 or M20-7851143 if different plating options are required. Verify mechanical dimensions against alternative DIL socket assemblies from other manufacturers to ensure footprint compatibility.
