M20-7823346

Overview

The Harwin M20-7823346 is a 33-position female socket receptacle connector from the M20 series. It features a 2.54 mm (0.1 inch) pitch and utilizes through-hole solder termination for PCB mounting. The housing is constructed from black nylon, providing UL94 V-0 flammability rating. Designed for board-to-board or cable applications, it supports a working temperature range of -40°C to +105°C. The contacts are made of bronze with tin plating to ensure reliable electrical performance in industrial environments.

Feature Summary

• Compact single-row design optimized for high-density PCB layouts
• Robust double-beam contact structure enhances connection reliability
• Compatible with standard SMT reflow processes despite being a through-hole component

Applications

• Embedded PC systems
• Motherboard interconnections
• Industrial monitoring equipment
• Communication devices

Procurement Notes

Verify the specific pin count and orientation against the schematic before ordering. Confirm that the tin-plated contacts meet the corrosion resistance requirements for the intended operating environment. Ensure the PCB footprint matches the 2.54 mm pitch specification to guarantee proper mechanical fit during assembly.

Selection Notes

Select this model when a 33-channel interface is required within space-constrained designs. The M20 series offers a balance between current carrying capacity and compact form factor. Consider the straight orientation for vertical mating needs. Verify compatibility with corresponding male headers in the same series for secure locking.

Part Context

This component belongs to the Harwin M20 series, a widely adopted standard for rectangular connectors. The series is known for its versatility in both single and double row configurations. It serves as a foundational interconnect solution for various electronic assemblies requiring robust mechanical and electrical connections.

Replacement Considerations

Direct substitutes include other Harwin M20 series sockets with identical 33-position counts and 2.54 mm pitch. Cross-brand replacements require careful verification of footprint dimensions and contact geometry to ensure mechanical interchangeability without redesigning the PCB.
