AW140-EG-G28C2

Overview

The AW140-EG-G28C2 is a 28-position unshrouded header connector from the AW140 series by Assmann WSW Components. It features a 2.54 mm (0.100 inch) pitch and is designed for through-hole mounting on printed circuit boards. The connector supports a voltage rating of 250V and carries a current rating of 3A. Contact materials consist of brass with gold plating to ensure reliable signal transmission. The housing is constructed from polybutylene terephthalate (PBT), providing thermal stability and mechanical strength for board-to-board applications.

Feature Summary

• Unshrouded single-row header design for direct board-to-board interconnection
• Gold-plated brass contacts housed in durable PBT material
• Through-hole mounting configuration ensuring secure PCB attachment

Applications

• Board-to-board electrical interconnections
• General-purpose electronic circuit assembly
• Industrial control system hardware integration

Procurement Notes

Verify the exact pin count and orientation against schematic requirements before ordering. Confirm that the through-hole footprint matches the target PCB layout. Ensure compatibility with mating connectors within the same series to maintain proper engagement and electrical continuity during operation.

Selection Notes

Select this component when a standard 2.54mm pitch header is required for high-reliability connections. Consider the 3A current rating and 250V voltage limit for circuit design constraints. Evaluate the unshrouded style against environmental protection needs, as it lacks side walls compared to shrouded alternatives.

Part Context

This part belongs to the AW140 series, which offers various pin counts and configurations. The suffix indicates specific attributes such as contact count and termination type. Similar parts in the lineup include different position variants like AW140-EG-G36D or AW140-EG-G28C1, allowing designers to scale connectivity options while maintaining consistent mechanical interfaces.

Replacement Considerations

Direct substitutes may include other manufacturers' headers with identical 2.54mm pitch and 28 positions. Verify that alternative components match the through-hole termination style and gold-plated contact specifications to ensure functional equivalence without redesigning the PCB footprint.
