AW140-EG-G25A

Overview

The AW140-EG-G25A is a single-row pin header from the ASSMANN WSW AW140 series, designed for board-to-board connections. It features 25 positions with a 2.54 mm pitch and operates at 250 V and 3 A. Constructed with brass contacts gold-plated for conductivity and a PBT insulator, it supports through-hole mounting via solder termination. The component functions as a male connector in a straight orientation without a cover, ensuring reliable electrical interfacing within specified thermal limits.

Feature Summary

• Single-row configuration with 25 positions for standardized interconnects
• Gold-plated brass contacts ensure stable signal transmission
• PBT housing provides structural integrity and thermal resistance
• Through-hole solder termination enables secure PCB attachment

Applications

• Board-to-board electrical interconnections
• General electronic circuit assembly
• Industrial control module interfaces

Procurement Notes

Verify the specific suffix code to confirm exact tail pin length and mating pin specifications, as variations exist within the AW140 series. Ensure compatibility with mating female headers regarding contact geometry and insulation height. Confirm that the operating temperature range of -40°C to 105°C meets the environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component when a 25-position single-row header is required for rigid board-to-board applications. The 2.54 mm pitch aligns with standard PCB grid layouts. Consider the gold plating for corrosion resistance and the PBT material for heat stability during soldering processes. Validate mechanical fit against mating connectors to ensure proper engagement depth and alignment tolerance.

Part Context

This part belongs to the AW140 series of ASSMANN WSW Components, which specializes in high-reliability interconnect solutions. The series offers various position counts and pin lengths to accommodate diverse design constraints. As a standard pin header, it serves as a fundamental building block for creating modular electronic systems requiring robust and repeatable physical connections between circuit boards.

Replacement Considerations

Compatible substitutes include other 25-position, 2.54mm pitch single-row headers from ASSMANN WSW or equivalent manufacturers. Verify that replacement parts match the current rating, voltage rating, and terminal type. Ensure the insulating material and operating temperature range are identical to maintain system reliability and safety compliance.
