Overview
The AW140-EG-G21B is a single-row male pin header connector from the AW140 series by Assmann WSW Components. It features a 2.54 mm (0.100 inch) pitch and supports 21 positions. The connector is designed for through-hole mounting with straight orientation, suitable for board-to-board applications. It has a current rating of 3A per contact and a voltage rating of 250V AC/DC. The housing is constructed from PBT material, while contacts are made of brass with gold plating. The operating temperature range spans from -40°C to 105°C.
Feature Summary
- Gold-plated brass contacts ensure reliable signal transmission and corrosion resistance.
- PBT housing provides thermal stability and mechanical durability within specified temperature ranges.
- Straight through-hole design facilitates standard PCB integration.
Applications
- Automotive body electronics and lighting systems
- Communications equipment interconnections
- Datacom module interfaces
- Personal electronics assemblies
Procurement Notes
Verify the specific suffix code against official datasheets to confirm pin count and orientation. Ensure compatibility with mating socket connectors regarding pitch and row configuration. Check for any specific environmental certifications required for the target application before finalizing procurement orders.
Selection Notes
Select this component when a 21-position, single-row male header is required for board-to-board connections. Consider the 2.54mm pitch constraint and through-hole mounting method. Evaluate the 3A current rating and 250V voltage limits against circuit requirements. Confirm that the straight orientation fits the mechanical layout constraints of the assembly.
Part Context
This part belongs to the AW140 series of standard pin headers. The series offers various pin counts and configurations for general electronic interconnects. The AW140-EG-G21B specifically addresses needs for 21-position connections in compact electronic designs requiring robust through-hole termination.
Replacement Considerations
Compatible substitutes include other 21-position, 2.54mm pitch single-row male headers from Assmann WSW or other manufacturers, provided they match the current, voltage, and mounting specifications.
