Overview
The AW140-EA-G31J is a single-row pin header connector from the AW140 series, manufactured by Assmann WSW Components. It features 31 positions with a 2.54 mm (0.100 inch) pitch and is designed for right-angle board-to-board connections. The component utilizes brass contacts with gold plating and a polybutylene terephthalate (PBT) housing. Rated for 3A current and 250V voltage, it supports through-hole mounting with solder termination. The operating temperature range spans from -40°C to 105°C.
Feature Summary
- Right-angle orientation facilitates compact PCB layout configurations
- Gold-plated brass contacts ensure reliable signal transmission
- Polybutylene terephthalate housing provides thermal stability
Applications
- Board-to-board interconnects in electronic assemblies
- Signal routing in industrial control systems
- Connection points in consumer electronics hardware
Procurement Notes
Verify the specific suffix of the part number to confirm contact finish and mating length requirements. Ensure the right-angle configuration aligns with the mechanical design constraints of the target assembly. Cross-reference the 31-position count against schematic diagrams to prevent mismatched connectivity during integration.
Selection Notes
Select this model when a right-angle, single-row header is required for rigid board connections. The 2.54 mm pitch is standard for general-purpose electronics. Consider the 3A rating and 250V limit against circuit demands. Verify that the through-hole mounting style matches the PCB fabrication capabilities.
Part Context
This component belongs to the AW140 series of connectors, which offers various row counts and orientations. The AW140 line is characterized by its robust construction and standardized spacing. This specific variant focuses on high-density single-row applications requiring angular insertion.
Replacement Considerations
Compatible substitutes include other 31-position, 2.54mm pitch right-angle headers from different manufacturers, provided they match the current rating and housing material specifications.
