M20-7873746

Overview

The M20-7873746 is a dual in-line (DIL) socket assembly manufactured by Harwin, designed for through-hole mounting on printed circuit boards. It features a 2.54 mm pitch and consists of 37 positions arranged in two rows. The connector utilizes tin-plated contacts to ensure reliable electrical connectivity. This component belongs to the M20 series, which provides industrial-standard headers and wire housings suitable for board-to-board applications.

Feature Summary

Dual row configuration with 37 total positions
Through-hole solder termination method
Tin-plated contact surfaces for conductivity

Applications

Board-to-board interconnections
Industrial electronic assemblies
PCB header integration

Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions or discontinuation. Confirm RoHS compliance details directly with the manufacturer before procurement. Ensure that the specific tin plating variant matches design requirements. Check for any regional shipping limitations or distributor constraints that may affect acquisition timelines.

Selection Notes

Select this part when a 37-position DIL socket is required for through-hole implementation. The 2.54 mm pitch aligns with standard industrial spacing requirements. Consider the M20 series compatibility if mating with corresponding pin headers. Evaluate mechanical height constraints and thermal performance during reflow processes relative to the specified housing material properties.

Part Context

This component is part of the Harwin M20 series, a range of PCB connectors offering various row counts and position options. The series supports both single and dual configurations with pitches of 2.54 mm. These connectors are engineered for high reliability in demanding environments, utilizing durable materials and robust contact designs to maintain signal integrity over extended operational lifespans.
