Overview
The AW140-EG-G40A1 is a single-row pin header from the ASSMANN WSW AW140 series, designed for board-to-board connectivity. It features 40 contacts with a 2.54 mm pitch and supports up to 3A current at 250V. Constructed with brass gold-plated contacts and polybutylene terephthalate housing, it utilizes through-hole solder termination. The component operates within a temperature range of -40°C to 105°C and is available in straight orientation without a cover.
Feature Summary
- Single-row configuration with 40 positions for high-density interconnection
- Gold-plated brass contacts ensure reliable conductivity and corrosion resistance
- Polybutylene terephthalate housing provides structural stability and thermal endurance
Applications
- Board-to-board electrical connections
- High-density circuit board interconnects
- Industrial electronic assemblies requiring robust signal transmission
Procurement Notes
Verify the specific suffix code against official manufacturer documentation to confirm exact tail pin length and mating pin specifications. Ensure the selected variant matches the required mechanical dimensions for the target PCB layout. Cross-reference the part number with authorized distributor catalogs to confirm availability and compliance with regional standards before finalizing procurement orders.
Selection Notes
Select this component when a 40-position, single-row connector is required for rigid board-to-board applications. Verify that the 2.54 mm pitch aligns with the mating connector footprint. Confirm that the through-hole mounting style and straight orientation fit the assembly constraints. Ensure the operating temperature range meets the environmental requirements of the end application.
Part Context
This component belongs to the AW140 series of pin headers manufactured by ASSMANN WSW Components. The series offers various contact counts and tail lengths to accommodate different board thicknesses. The AW140-EG-G40A1 specifically addresses needs for 40-contact interfaces with standardized 2.54 mm spacing, providing a reliable solution for dense electronic packaging.
Replacement Considerations
Compatible substitutes include other ASSMANN WSW AW140 series variants with matching 40-pin counts and 2.54 mm pitch. Verify equivalent electrical ratings and mechanical dimensions before substitution.
