Overview
The AW140-EA-G28H is a single-row pin header connector from the AW140 series by Assmann WSW Components. It features 28 positions with a 2.54 mm pitch, designed for board-to-board connections. The component utilizes gold-plated brass contacts and a polybutylene terephthalate (PBT) housing. Rated for 3 A current and 250 V voltage, it supports through-hole mounting with right-angle orientation. Operating temperatures range from -40°C to 105°C.
Feature Summary
- Right-angle design facilitates compact board stacking
- Gold-plated contacts ensure reliable conductivity
- Through-hole termination provides secure PCB attachment
Applications
- Board-to-board interconnects
- Electronic module assembly
- Industrial control systems
Procurement Notes
Verify the exact pin count matches the '28' designation in the model number. Confirm right-angle orientation and single-row configuration align with design requirements. Ensure PBT material compatibility with environmental conditions. Cross-reference the specific suffix against manufacturer documentation to confirm plating thickness and contact material specifications.
Selection Notes
Select this component when a right-angle, single-row header with 28 pins is required. The 2.54 mm pitch is standard for general electronics. Consider the 3 A rating and 250 V limit for circuit safety. Verify that the through-hole mounting method suits the PCB fabrication capabilities and mechanical stress requirements of the application.
Part Context
This part belongs to the AW140 series, which offers various pin counts and orientations. Similar models include AW140-EA-G30H and AW140-EA-G25H-DG. The series provides consistent electrical characteristics across different configurations, allowing for modular design flexibility while maintaining standardized interface dimensions.
Replacement Considerations
Compatible substitutes within the same series include AW140-EA-G30H and AW140-EA-G25H-DG. These alternatives share identical pitch, voltage, and current ratings. Ensure the replacement maintains the right-angle orientation and single-row layout to preserve mechanical fit.
