M20-7873246

Overview

The Harwin M20-7873246 is a single-row PCB socket connector from the M20 series, designed for board-to-board applications. It features a 2.54 mm pitch and provides 32 positions. The component utilizes through-hole straight termination for secure PCB mounting. Contacts are made of phosphor bronze with nickel plating, rated for 12 A current. The housing is constructed from high-temperature liquid crystal polymer (LCP) meeting UL94V-0 standards. Operating temperature ranges from -55°C to 105°C.

Feature Summary

High-density design utilizing compact LCP housing for space-constrained PCB layouts
Dual-beam contact structure ensures reliable electrical connection and mechanical durability
Compatible with standard SMT reflow processes despite being a through-hole component

Applications

Embedded PC systems
Motherboard interconnections
Large electronic system backplanes

Procurement Notes

Verify the specific suffix '46' corresponds to the required nickel-plated tin finish and standard packaging configuration. Confirm that the 32-position single-row format matches the target PCB footprint. Ensure compatibility with mating pin headers from the same M20 series family to maintain alignment and signal integrity.

Selection Notes

Select this model when a high-count, single-row through-hole solution is required for board-to-board connections. The 2.54 mm pitch offers standard spacing compatibility. Consider the 12 A rating and -55°C to 105°C range against environmental demands. Verify that the straight orientation fits the assembly height constraints compared to right-angle alternatives.

Part Context

This component belongs to the Harwin M20 series, a widely adopted industrial standard for 2.54 mm pitch connectors. The series is characterized by its robust construction and suitability for high-density applications in computing and communication equipment. The M20-7873246 specifically represents the 32-position variant within the single-row socket lineup.
