Overview
The AW140-EG-G21D is a 21-position connector header from the AW140 series, manufactured by Assmann WSW Components. It features a 2.54 mm (0.100 inch) pitch and utilizes through-hole mounting for secure PCB attachment. The component is designed as a straight, single-row pin header without an integrated cover. It supports a voltage rating of 250V and a current capacity of 3A. The housing is constructed from polybutylene terephthalate (PBT), providing structural integrity and thermal stability for standard electronic interconnections.
Feature Summary
- Straight single-row pin header configuration
- Through-hole mounting for board-to-board connection
- Polybutylene terephthalate (PBT) housing material
Applications
- Automotive body electronics and lighting systems
- Communications equipment signal routing
- Datacom module interconnects
- Personal electronics assembly
Procurement Notes
Verify the specific ordering suffix to confirm contact plating and housing color variants. Ensure the selected part matches the required 21-position count and 2.54mm pitch specifications. Confirm that the straight orientation aligns with the mechanical layout requirements. Cross-reference the datasheet for precise mating force and insulation resistance values before finalizing the procurement order.
Selection Notes
Select this component when a 21-pin through-hole header is required for 250V applications. The 3A current rating suits moderate power distribution needs. Verify compatibility with mating sockets in the same AW140 series family. Consider the PBT material properties for environmental resistance during operation.
Part Context
This part belongs to the AW140 series of connectors, which offers various position counts ranging from single pins to higher density configurations. The series provides standardized dimensions for reliable interchangeability within Assmann WSW's product line. Similar models include AW140-EG-G21C1 and AW140-EG-G21D variations differing in housing color or plating.
Replacement Considerations
Direct substitutes within the same series include AW140-EG-G21C1. Verify that alternative parts maintain the identical 21-position count and 2.54mm pitch. Ensure mechanical footprint compatibility with existing PCB layouts before substitution.
