AW140-EA-Z18H

Overview

The AW140-EA-Z18H is a single-row pin header connector from the AW140 series, manufactured by Assmann WSW Components. It features 18 positions with a 2.54 mm (0.100 inch) pitch. Designed for through-hole mounting, this right-angle connector utilizes gold-plated brass contacts to ensure reliable signal transmission. The housing is constructed from polybutylene terephthalate (PBT), providing durability and thermal stability. Rated for 3 A current and 250 V voltage, it operates within a temperature range of -40°C to +105°C. This component serves as a male contact interface for board-to-board connections.

Feature Summary

• Right-angle design facilitates compact vertical circuit board integration.
• Gold-plated contacts provide corrosion resistance and stable conductivity.
• Through-hole termination ensures secure mechanical attachment to PCBs.

Applications

• Board-to-board interconnections in electronic assemblies
• General-purpose signal routing on printed circuit boards
• Industrial control system hardware interfaces

Procurement Notes

Verify that the specific part number matches the required 18-position configuration and right-angle orientation. Confirm that the gold plating specification aligns with your environmental requirements. Ensure the through-hole footprint corresponds to standard 2.54 mm grid layouts. Check for RoHS compliance status if restricted substances are a concern for your manufacturing process.

Selection Notes

Select this model when a right-angle male header is required for rigid board stacking or vertical mating scenarios. The 2.54 mm pitch is standard for general electronics, while the gold finish offers superior performance over tin in corrosive environments. Consider the PBT material properties for applications requiring higher thermal resistance compared to standard nylon housings.

Part Context

This component belongs to the AW140 series of connectors, which are characterized by their robust construction and standardized dimensions. The series includes various pin counts and orientations, allowing for flexible design options. The AW140-EA-Z18H specifically addresses the need for a medium-density connection point with high reliability standards.

Replacement Considerations

Compatible substitutes include other 18-pin right-angle headers with identical 2.54 mm pitch and through-hole termination. Ensure replacement parts maintain the same current rating and voltage specifications. Verify that the housing material and contact plating meet the original design's performance criteria.
