AW140-EA-Z31H

Overview

The AW140-EA-Z31H is a single-row pin header connector from the AW140 series, manufactured by Assmann WSW Components. Designed for board-to-board applications, this component features 31 positions with a 2.54 mm pitch. It utilizes right-angle orientation and through-hole mounting for secure PCB integration. The contacts are constructed from brass with gold plating to ensure reliable conductivity. Rated for 3A current and 250V voltage, it operates within a temperature range of -40°C to 105°C. The housing is made of polybutylene terephthalate (PBT), providing structural stability without a cover.

Feature Summary

• Right-angle configuration facilitates compact vertical interconnections between circuit boards.
• Gold-plated brass contacts provide durable electrical performance and corrosion resistance.
• Polybutylene terephthalate (PBT) housing offers thermal stability and mechanical strength.
• Through-hole termination ensures robust physical attachment to the printed circuit board.

Applications

• Board-to-board signal transmission in electronic assemblies
• Interconnection modules requiring right-angle routing
• Industrial control systems utilizing standard 2.54mm spacing

Procurement Notes

Verify the specific part number AW140-EA-Z31H against official manufacturer documentation to confirm the 31-position count and right-angle orientation. Ensure compatibility with mating connectors regarding pitch and contact type. Cross-reference technical specifications such as current rating and temperature limits with system requirements before procurement to prevent integration errors.

Selection Notes

Select this component when a right-angle, single-row header is required for board-to-board connections. The 2.54 mm pitch is standard for general-purpose electronics. Consider the through-hole mounting method for applications needing high mechanical retention. Verify that the 3A current rating and 250V voltage limit align with the operational parameters of the target circuit design.

Part Context

This connector belongs to the AW140 series, which provides various configurations including different pin counts and orientations. The AW140 line is designed for reliable connectivity in standard electronic environments. Assmann WSW Components supplies this series as part of their broader portfolio of standard and customized connectivity solutions for global markets.

Replacement Considerations

Compatible substitutes include other 31-position, 2.54 mm pitch, right-angle pin headers from the same or alternative manufacturers. Ensure replacement parts match the through-hole mounting style and gold-plated contact specifications. Verify that the housing material and temperature ratings meet or exceed the original component's capabilities.
