AW140-EA-G31H

Overview

The AW140-EA-G31H is a single-row male pin header from the AW140 series, manufactured by Assmann WSW Components. Designed for board-to-board connections, this connector features 31 positions with a 2.54 mm pitch. It utilizes gold-plated brass contacts housed in a PBT (Polybutylene Terephthalate) insulator. The component supports through-hole mounting and operates within a temperature range of -40°C to +105°C. Rated for 250V and 3A per contact, it offers reliable electrical performance for standard electronic assemblies.

Feature Summary

• Single-row male pin configuration for direct board interconnection
• Gold-plated brass contacts ensure stable signal transmission
• PBT housing material provides thermal stability up to 105°C

Applications

• General-purpose board-to-board interconnects
• Industrial control system circuit boards
• Consumer electronics internal wiring

Procurement Notes

Verify the specific pin count and orientation against design requirements before ordering. Confirm that the supplier provides genuine Assmann WSW components with traceable documentation. Ensure compatibility with mating sockets regarding height and locking mechanisms. Check for any specific handling instructions related to the through-hole soldering process to maintain joint integrity.

Selection Notes

Select this model when a 31-position single-row header is required for rigid board-to-board applications. The 2.54 mm pitch is standard for general electronics, ensuring broad availability of mating parts. Consider the straight or right-angle variant based on spatial constraints, as the EA suffix typically denotes specific mechanical configurations within the AW140 family. Verify voltage and current ratings match the application's electrical load.

Part Context

The AW140 series represents a line of high-density connectors designed for versatile electronic applications. This specific part belongs to the header category, providing a robust connection point for PCB assemblies. The series is known for its consistent dimensional accuracy and reliable contact performance across various industrial and commercial environments.

Replacement Considerations

Direct substitutes include other AW140 series headers with identical pin counts and pitch, such as AW140-EA-G31G or AW140-EG-G31H, provided the mechanical orientation matches the design. Cross-brand replacements require careful verification of footprint dimensions, contact plating, and insulation material properties to ensure functional equivalence.
