AW140-EG-Z21E

Overview

The AW140-EG-Z21E is a board-to-board connector header from the AW140 series, manufactured by ASSMANN WSW Components. It features 21 positions with a 2.54 mm (0.100 inch) pitch. The connector utilizes a single row configuration and is designed for right-angle through-hole mounting. Electrical specifications include a current rating of 3A per contact and a voltage rating of 250V AC/DC. The housing is constructed from polybutylene terephthalate (PBT), while contacts are made of brass with gold plating to ensure reliable signal transmission.

Feature Summary

• Right-angle through-hole mounting design for efficient PCB space utilization
• Gold-plated brass contacts for enhanced conductivity and corrosion resistance
• Polybutylene terephthalate (PBT) housing material for thermal stability

Applications

• High-density electronic circuit boards requiring compact interconnects
• Industrial control systems utilizing standard 2.54mm pitch interfaces
• Consumer electronics assemblies needing reliable right-angle connections

Procurement Notes

Verify the specific suffix 'Z21E' against the manufacturer's official datasheet to confirm pin count and orientation details. Ensure compatibility with mating socket connectors in the same AW140 series family. Check for RoHS compliance documentation if required for your region. Confirm that the right-angle form factor matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a single-row, right-angle header is required for 21-position connections. The 2.54mm pitch is standard for general-purpose electronics. Consider the 3A current rating for power distribution needs. The through-hole termination method offers mechanical robustness compared to surface mount alternatives. Ensure the mating connector supports the specified 250V voltage rating.

Part Context

This part belongs to the AW140 series of board-to-board connectors from ASSMANN WSW Components. The series is characterized by its 2.54mm pitch and availability in various row counts and orientations. The AW140 line is widely used in industrial and commercial applications due to its standardized dimensions and reliable performance characteristics across different environmental conditions.

Replacement Considerations

Compatible substitutes must match the 21-position count, 2.54mm pitch, right-angle orientation, and through-hole termination. Verify that alternative manufacturers offer equivalent current ratings of 3A and compatible housing materials. Cross-reference pinout configurations to ensure electrical continuity without modification.
