AW140-EG-Z40A

Overview

The AW140-EG-Z40A is a single-row pin header connector from the AW140 series, manufactured by ASSMANN WSW. It features 40 positions with a 2.54 mm (0.100 inch) pitch. Designed for board-to-board applications, it utilizes through-hole termination and straight orientation. The contacts are made of brass with gold plating, rated for 3A current and 250V voltage. The housing is constructed from polybutylene terephthalate (PBT). Operating temperature ranges from -40°C to 105°C.

Feature Summary

• Single-row configuration with 40 contact positions for high-density interconnects
• Gold-plated brass contacts ensure reliable signal transmission and corrosion resistance
• Polybutylene terephthalate (PBT) housing provides thermal stability and mechanical strength
• Through-hole mounting with straight orientation facilitates standard PCB assembly

Applications

• Board-to-board interconnections in electronic assemblies
• Industrial control systems requiring robust connectivity
• Consumer electronics with standard 2.54mm spacing requirements
• General-purpose circuit board expansion and module interfacing

Procurement Notes

Verify the exact suffix against official manufacturer documentation to confirm pin length and mating height specifications. Ensure compatibility with corresponding socket connectors within the same AW140 series family. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Check for any specific handling or storage requirements indicated in the datasheet.

Selection Notes

Select this component when a 40-position, single-row header is required for rigid board connections. The 2.54mm pitch is standard for many legacy and general-purpose designs. Consider the straight orientation and through-hole method for standard PCB layouts. Evaluate the 3A current rating and 250V voltage limit against system requirements to ensure safe operation under load conditions.

Part Context

This part belongs to the AW140 series of board-to-board connectors. The series offers various configurations including different row counts, orientations, and pin lengths. The AW140-EG-Z40A specifically denotes a 40-position variant. Similar parts in the series include AW140-EG-G36A and AW140-EA-G36H, differing in position count and orientation.

Replacement Considerations

Direct substitutes must match the 40-position count, 2.54mm pitch, and single-row format. Verify that alternative headers share the same through-hole termination and straight orientation. Ensure mating sockets are compatible with the specified contact dimensions and housing style. Consult manufacturer cross-reference lists for verified equivalent part numbers.
