M20-7833642

Overview

The M20-7833642 is a dual-in-line (DIL) vertical printed circuit board socket assembly manufactured by Harwin Inc. within the M20 series. It features a 2.54 mm pitch and is designed for through-hole mounting. The connector utilizes phosphor bronze contacts with gold plating to ensure reliable electrical performance in demanding environments. Constructed with high-temperature liquid crystal polymer, the housing meets UL94 V-0 flammability ratings. This component supports board-to-board or cable stacking applications, offering robust mechanical stability and consistent signal integrity across industrial and telecommunications sectors.

Feature Summary

• Dual-in-line configuration with vertical orientation for compact PCB integration
• Gold-plated phosphor bronze contacts for enhanced conductivity and corrosion resistance
• High-temperature liquid crystal polymer housing rated UL94 V-0 for thermal stability

Applications

• Embedded PC systems
• Industrial monitoring equipment
• Telecommunications infrastructure

Procurement Notes

Verify current availability status as this part number may be subject to obsolescence or limited stock conditions. Confirm that the specific contact count and row configuration match the design requirements before ordering. Ensure compatibility with mating header assemblies from the same M20 series family to maintain proper alignment and connection reliability during installation.

Selection Notes

Select this component when a vertical DIL socket with 2.54 mm pitch is required for through-hole PCB assembly. Consider the M20 series characteristics for high-density applications needing durable, gold-plated contacts. Evaluate the operating temperature range and mechanical height constraints to ensure the connector fits within the designated space without interfering with adjacent components or enclosure structures.

Part Context

This connector belongs to the Harwin M20 series, a widely adopted standard for board-to-board connections. The series is known for its compact design and ability to withstand reflow soldering processes similar to SMT components. The M20-7833642 specifically represents a dual-row variant, providing higher pin counts in a small footprint compared to single-row alternatives, making it suitable for complex electronic assemblies.

Replacement Considerations

Check for direct substitutes within the M20 series that share identical pitch, row count, and termination type. Verify if alternative manufacturers offer compatible DIL sockets with matching dimensions and electrical ratings. Ensure any replacement maintains the same gold plating specification and UL94 V-0 rating for equivalent performance and safety compliance.
