Overview
The M20-7854042 is a rectangular socket connector from the Harwin M20 series, featuring 40 positions with a 2.54 mm pitch. It utilizes a single row configuration and is designed for through-hole mounting on printed circuit boards. The component incorporates male pin contacts that are gold-plated to ensure reliable signal transmission. It operates within a temperature range of -40°C to +105°C and meets RoHS environmental standards.
Feature Summary
- Features a compact single-row design optimized for high-density PCB layouts
- Utilizes durable gold-plated male pins for enhanced conductivity and corrosion resistance
- Constructed with UL94V-0 rated housing material for thermal stability
Applications
- Board-to-board interconnections in industrial control systems
- Signal routing in telecommunications equipment
- General-purpose electronic assemblies requiring robust connectivity
Procurement Notes
Verify the specific contact plating and housing material against the official datasheet before integration. Confirm that the through-hole mounting style aligns with the target PCB fabrication capabilities. Ensure the operating temperature range satisfies the environmental requirements of the final application environment.
Selection Notes
Select this component when a single-row, through-hole male header is required for board-to-board applications. Consider the 2.54 mm pitch compatibility with mating connectors. Evaluate the gold plating requirement for long-term reliability in demanding environments compared to tin alternatives.
Part Context
This part belongs to the M20 series, which offers various configurations including surface mount and vertical options. The series is engineered for high-reliability applications in harsh environments. The M20-7854042 specifically addresses needs for horizontal, through-hole mounting solutions within this product family.
Replacement Considerations
Consult the manufacturer's obsolescence notices for potential end-of-life status. Verify cross-reference availability with other distributors if supply chain continuity is a concern.
