AW140-EG-Z28B

Overview

The AW140-EG-Z28B is a 28-position rectangular connector header from the AW140 series, manufactured by Assmann WSW Components. Designed for board-to-board applications, this component features a 2.54 mm pitch and utilizes through-hole termination for secure PCB mounting. The contacts are constructed from brass with gold plating to ensure reliable signal transmission. The housing is made of polybutylene terephthalate (PBT), providing structural integrity and thermal stability within an operating temperature range of -40°C to 105°C. Rated for 250V and 3A, it supports standard industrial electronic interconnect requirements.

Feature Summary

• Gold-plated brass contacts ensure durable electrical connectivity
• Polybutylene terephthalate housing provides thermal resistance
• Through-hole mounting secures stable board-to-board positioning

Applications

• Board-to-board interconnection systems
• Industrial electronic equipment assemblies
• Consumer electronics internal wiring

Procurement Notes

Verify the specific part number AW140-EG-Z28B against official manufacturer documentation to confirm pin count and orientation. Ensure compatibility with mating sockets regarding pitch and housing dimensions. Check RoHS compliance status if required for your region. Confirm surface mount or through-hole assembly processes match the component's termination style before ordering.

Selection Notes

Select this component when a 28-position straight header is required for rigid board connections. The 2.54 mm pitch suits standard spacing layouts. Gold plating is preferred for environments requiring corrosion resistance. Verify that the 3A current rating and 250V voltage limit align with the circuit design specifications. Consider the PBT material properties for thermal management needs.

Part Context

This part belongs to the AW140 series of rectangular connectors, which are widely used in various electronic assemblies. The series offers multiple positions and configurations to support diverse board-to-board interface needs. Assmann WSW Components specializes in such interconnect solutions, ensuring consistency across product lines for system integrators.

Replacement Considerations

Compatible substitutes include other 28-position, 2.54mm pitch headers from different manufacturers, provided they match the mechanical footprint and electrical ratings. Ensure the replacement maintains the same through-hole termination and gold contact plating for equivalent performance.
