M20-7881942

Overview

The M20-7881942 is a rectangular connector from the Harwin M20 series, classified under Headers and Wire Housings. It functions as a dual in-line (DIL) socket strip with a total of 38 positions arranged in two rows. The component utilizes a 2.54 mm pitch and features horizontal orientation for surface mounting. Contact plating consists of gold over tin to ensure reliable signal transmission. The housing material is designed for durability in standard electronic assemblies.

Feature Summary

Dual in-line configuration providing 38 connection points across two rows
Horizontal mounting style suitable for specific PCB layout requirements
Gold and tin contact plating for enhanced conductivity and corrosion resistance

Applications

General purpose electronic circuit interconnections
Industrial control panel wiring
Consumer electronics assembly

Procurement Notes

Verify the current lifecycle status before procurement, as this part may be obsolete or discontinued. Confirm that the horizontal orientation and DIL socket type match the design requirements. Ensure compatibility with mating pin headers regarding pitch and row count. Check for RoHS compliance details if required by project specifications.

Selection Notes

Select this component when a horizontal dual-row socket interface is required. The 2.54 mm pitch is standard for many through-hole applications. Consider the gold-tin plating for environments where oxidation resistance is critical. Verify that the PCB footprint accommodates the horizontal profile and spacing constraints of the M20 series.

Part Context

This part belongs to the Harwin M20 series, which offers a range of header and socket solutions. The M20 series is known for its versatility in various connector configurations.
