Overview
The AW140-EA-G21J is a single-row pin header connector from the AW140 series by Assmann WSW Components. It features 21 positions with a 2.54 mm (0.100 inch) pitch. Designed for through-hole mounting, this right-angle connector utilizes gold-plated brass contacts to ensure reliable signal transmission. The housing is constructed from polybutylene terephthalate (PBT), providing durability and thermal stability. Rated for 3 A current and 250 V voltage, it operates within a temperature range of -40°C to +105°C. This board-to-board connector is unshrouded and intended for direct soldering to printed circuit boards.
Feature Summary
- Right-angle design facilitates compact board-to-board interconnections
- Gold-plated contacts ensure corrosion resistance and low contact resistance
- Through-hole termination provides secure mechanical attachment
Applications
- Board-to-board connectivity in electronic assemblies
- Interfacing between daughterboards and motherboards
- General-purpose signal routing in consumer electronics
Procurement Notes
Verify the specific suffix codes against the manufacturer's official datasheet to confirm pin count, orientation, and plating specifications. Ensure compatibility with mating female headers regarding pitch and shroud design. Confirm that the through-hole footprint matches the PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a right-angle, single-row connection is required for space-constrained designs. The 2.54 mm pitch is standard for general electronics, ensuring broad availability of mating parts. Consider the 3 A current rating and 105°C temperature limit to ensure suitability for the target application's electrical and thermal environment.
Part Context
This part belongs to the AW140 series, which offers various configurations including different pin counts and orientations. Assmann WSW specializes in IC sockets and IDC connectors, but this specific model is a standard pin header. The series provides options for both straight and right-angle mounts to accommodate diverse PCB layout needs.
Replacement Considerations
Compatible substitutes include other 21-position, 2.54 mm pitch, right-angle pin headers from manufacturers such as Samtec or Molex, provided they match the terminal type and housing material specifications. Verify that any replacement maintains the same current and voltage ratings.
