M20-7830442

Overview

The M20-7830442 is an 8-position (4+4) dual in-line (DIL) female socket receptacle from the Harwin M20 series. It features a 2.54 mm (0.1 inch) pitch and is designed for through-hole mounting. The connector utilizes a straight orientation with a board height of 8.5 mm. Contact finishes include gold plating combined with tin, ensuring reliable signal transmission. This component is classified as a header and wire housing assembly intended for secure PCB interconnections.

Feature Summary

• Dual in-line configuration providing 4+4 positions for compact circuit integration
• Through-hole termination method ensures robust mechanical stability on printed circuit boards
• Selective contact plating combines gold durability with tin base material for corrosion resistance

Applications

• Industrial factory equipment control systems
• Data collection hardware interfaces
• Mobile maintenance tool connections
• Display control system assemblies

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number M20-7830442 with official Harwin documentation. Confirm that the received units match the specified 8-position DIL format and 2.54 mm pitch. Ensure storage conditions maintain the integrity of the selective gold and tin contact finishes prior to installation.

Selection Notes

Select this specific model when a low-profile, straight-mount female socket is required for 2.54 mm pitch applications. The 8.5 mm insulation height accommodates standard board thicknesses while maintaining vertical clearance constraints. Choose this variant over surface mount options if through-hole soldering provides the necessary mechanical strength for the target environment.

Part Context

This component belongs to the Harwin M20 series, which specializes in high-reliability rectangular connectors. The M20 line is engineered for demanding environments, offering various pin counts and termination styles. As a female socket receptacle, it pairs with male headers to establish secure electrical pathways in industrial and commercial electronic assemblies.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users requiring alternative components must evaluate generic 2.54 mm pitch DIL sockets based on matching position count, termination type, and physical dimensions.
