M20-7831042

Overview

The Harwin M20-7831042 is a 20-position vertical PCB socket from the M20 series, featuring a 2.54 mm pitch and two rows of ten contacts each. Designed for board-to-board interconnection, it utilizes through-hole solder termination with selective gold and tin plating on the contacts. The connector supports a rated current of 12 A and withstands voltages up to 1 kV. Constructed with a nylon housing, this straight female receptacle is RoHS compliant and intended for reliable signal and power transmission in electronic assemblies.

Feature Summary

• Vertical through-hole mounting configuration for direct PCB integration
• Selective gold and tin contact plating for enhanced conductivity and corrosion resistance
• High voltage insulation capability suitable for demanding electrical environments

Applications

• Board-to-board signal interconnection systems
• Industrial control panel wiring harnesses
• Test equipment connection interfaces

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to ensure correct contact plating and housing color specifications. Confirm that the selected variant matches the required 2.54 mm pitch and 20-contact configuration for your design. Check RoHS compliance status if restricted substances are a constraint for your manufacturing process.

Selection Notes

Select this component when a vertical, high-reliability socket with selective plating is required for 2.54 mm pitch applications. Ensure the PCB layout accommodates the through-hole tail dimensions and the nylon housing height. Consider the 12 A current rating and 1 kV voltage limit to verify suitability for the target circuit's electrical requirements.

Part Context

This part belongs to the Harwin M20 series, which provides standard 2.54 mm pitch connectors conforming to industry conventions for pin header and socket systems. The M20 series offers various configurations including headers, sockets, and terminal blocks, designed for robust performance in general electronic applications requiring reliable mechanical and electrical connections.

Replacement Considerations

Compatible substitutes include other 2.54 mm pitch, 2x10 position vertical sockets from manufacturers such as Samtec or Molex. Verify that alternative parts match the critical parameters: 2.54 mm pitch, 12 A current rating, 1 kV voltage rating, and through-hole termination type before implementation.
