AW140-EG-Z18C2

Overview

The AW140-EG-Z18C2 is a single-row pin header connector from the AW140 series by Assmann WSW Components. It features 18 positions with a 2.54 mm pitch and is designed for through-hole mounting. The contacts are made of brass with gold flash plating to ensure reliable conductivity. The housing is constructed from polybutylene terephthalate (PBT), providing thermal stability within an operating temperature range of -40°C to 105°C. Rated for 250V and 3A, this straight, unshrouded header utilizes solder termination for secure PCB attachment.

Feature Summary

• Single-row configuration with 2.54 mm spacing for standard board-to-board interconnects
• Gold flash plated brass contacts for enhanced corrosion resistance and signal integrity
• Thermally stable PBT housing supporting high-temperature soldering processes
• Straight orientation with through-hole solder termination for robust mechanical fixation

Applications

• General purpose electronic circuit board interconnections
• Industrial control system module interfaces
• Consumer electronics internal wiring harnesses
• Communication equipment signal routing

Procurement Notes

Verify the specific contact count and row configuration against the official datasheet before ordering. Confirm that the gold flash plating specification matches the application requirements for low-contact resistance. Ensure the through-hole footprint dimensions align precisely with the printed circuit board layout to guarantee proper insertion and solder joint quality during assembly.

Selection Notes

Select this component when a single-row, straight header is required for 2.54 mm pitch applications. The AW140 series offers a balance of electrical performance and mechanical durability suitable for general industrial use. Consider the 3A current rating and 250V voltage limit to ensure compliance with the target circuit's operational parameters and safety standards.

Part Context

This part belongs to the AW140 series of connectors manufactured by Assmann WSW Components. The series provides various pin counts and configurations for board-to-board connections. The AW140-EG-Z18C2 specifically denotes the 18-position variant with gold-plated contacts and a straight form factor, fitting into the broader ecosystem of standard pitch interconnect solutions.

Replacement Considerations

Direct substitutes may include other 18-position, 2.54 mm pitch single-row headers from different manufacturers. Verify compatibility regarding housing material, contact plating thickness, and overall height. Ensure that any alternative part meets the same electrical ratings and thermal specifications to maintain system reliability.
