AW140-EG-Z18E

Overview

The AW140-EG-Z18E is a single-row male pin header connector from the AW140 series by Assmann WSW Components. It features a 2.54 mm pitch and accommodates 18 contacts. Designed for board-to-board applications, it utilizes through-hole termination for secure PCB mounting. The housing is constructed from polybutylene terephthalate (PBT), while the contacts are made of brass with gold plating to ensure reliable conductivity. The component supports a rated voltage of 250V and a current capacity of 3A. It operates within a temperature range of -40°C to +105°C.

Feature Summary

• Single-row configuration with 18 positions for compact circuit integration
• Gold-plated brass contacts provide corrosion resistance and stable electrical performance
• Polybutylene terephthalate housing offers thermal stability and mechanical strength
• Through-hole termination ensures robust physical attachment to printed circuit boards

Applications

• Board-to-board interconnections in electronic assemblies
• Signal routing in industrial control systems
• Connection points in consumer electronics hardware
• General-purpose PCB header applications requiring 2.54mm spacing

Procurement Notes

Verify the specific tail pin length and mating pin height requirements against your design specifications, as these dimensions vary across the AW140 series variants. Confirm that the 18-position count matches the target footprint. Ensure compatibility with standard 2.54 mm pitch mating connectors. Check for any specific RoHS or REACH compliance documentation if required by your manufacturing standards before finalizing procurement.

Selection Notes

Select this model when a single-row, right-angle or straight header is needed for 18 signals. Compare tail pin lengths to ensure adequate solder joint formation on the target PCB thickness. Verify that the 3A current rating and 250V voltage limit meet the circuit's operational demands. Consider the gold plating for environments where oxidation resistance is critical for long-term contact reliability.

Part Context

This component belongs to the AW140 series, which provides a range of board-to-board headers with consistent 2.54 mm pitch. The series offers various row counts, orientations, and pin lengths to suit different assembly heights. The AW140-EG-Z18E specifically addresses needs for 18-contact connections, fitting into the broader ecosystem of Assmann WSW interconnect solutions designed for high-density PCB layouts.

Replacement Considerations

Direct substitutes include other AW140 series headers with identical 18-pin counts and 2.54 mm pitch, such as AW140-EG-G18 variants, provided the tail pin length and orientation match the original design constraints. Cross-brand replacements must strictly adhere to the 2.54 mm grid and 3A/250V ratings.
