AW140-EG-G21F

Overview

The AW140-EG-G21F is a single-row header connector from the AW140 series by Assmann WSW Components. It features 21 positions with a 2.54 mm (0.100 inch) pitch. The connector supports a current rating of 3A and a voltage rating of 250V. Constructed with brass contacts plated in gold, it utilizes a PBT housing. Designed for through-hole mounting, this straight male pin header is intended for board-to-board connections. The operating temperature range spans from -40°C to 105°C.

Feature Summary

• Single-row configuration with 21 positions for compact circuit integration
• Gold-plated brass contacts ensure reliable signal transmission
• PBT housing material provides structural stability
• Straight through-hole design facilitates standard PCB assembly

Applications

• Automotive body electronics and lighting systems
• Communications equipment interconnects
• Datacom module connections
• Personal electronics assemblies

Procurement Notes

Verify the specific suffix code against the manufacturer's official documentation to confirm exact contact plating thickness and housing color variations. Ensure the selected variant matches the required pin count and row configuration for the target application. Cross-reference the part number with the latest datasheet to confirm compliance with current RoHS directives and material specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-row, 21-position header is required for board-to-board applications. The 2.54 mm pitch is suitable for general-purpose digital and power signals within the specified electrical ratings. Consider the through-hole mounting style for robust mechanical attachment. Verify that the operating temperature range meets the environmental requirements of the end-use device.

Part Context

This component belongs to the AW140 series, which offers various pin counts and configurations from Assmann WSW Components. The series is designed for high-density connectivity solutions in consumer and industrial electronics. The AW140-EG-G21F specifically addresses needs for moderate channel counts with reliable electrical performance in space-constrained designs.

Replacement Considerations

Direct substitutes include other 21-position, 2.54mm pitch single-row headers from Assmann WSW such as the AW140-EG-G21C or AW140-EG-G21D, depending on housing color or specific plating requirements. Generic equivalents from other manufacturers must match the 2.54mm pitch, 3A current rating, and through-hole footprint dimensions to ensure mechanical and electrical compatibility.
