Overview
The AW140-EA-G38G is a single-row pin header from the AW140 series, manufactured by Assmann WSW Components. It features 38 positions with a 2.54 mm pitch and is designed for right-angle through-hole mounting. The connector system supports board-to-board connections. Rated for 250V and 3A, it operates within a temperature range of -40°C to 105°C. Contacts are gold-plated brass, housed in polybutylene terephthalate (PBT).
Feature Summary
- Right-angle orientation facilitates compact vertical circuit board integration.
- Gold-plated brass contacts ensure reliable conductivity and corrosion resistance.
- Polybutylene terephthalate housing provides thermal stability and mechanical strength.
Applications
- Board-to-board interconnections in electronic assemblies.
- High-density signal routing in industrial control systems.
- Consumer electronics requiring compact vertical mounting solutions.
Procurement Notes
Verify the exact position count against project requirements, as similar models exist with varying pin counts such as 36 or 38. Confirm that the right-angle form factor aligns with the mechanical constraints of the assembly. Ensure compatibility with mating sockets regarding contact length and housing dimensions before finalizing procurement decisions.
Selection Notes
Select this model when a right-angle configuration is necessary to save horizontal space on the PCB. The 2.54 mm pitch is standard for general-purpose applications. Consider the 3A current rating and 250V voltage limit to ensure electrical safety margins are met for the specific application load.
Part Context
This component belongs to the AW140 series of headers, which offers various configurations including straight and right-angle options. The series utilizes PBT housing and gold-plated contacts for durability. Similar parts in the lineup include AW140-EA-G36G and AW140-EA-G09H, differing primarily in position count and orientation.
Replacement Considerations
AW140-EA-G36G serves as a substitute with identical specifications but fewer positions. Ensure the reduced pin count meets the circuit design needs. Verify that the right-angle orientation and 2.54 mm pitch remain consistent across replacement candidates to maintain mechanical compatibility.
