Overview
The AW140-EG-Z21C2 is a pin header connector from the AW140 series, manufactured by Assmann WSW Components. It features a 2.54 mm (0.100 inch) pitch and provides 21 positions for board-to-board connections. The component utilizes through-hole mounting technology with straight orientation. It is rated for 250V AC/DC voltage and supports a current rating of 3A per contact. The housing material is polybutylene terephthalate.
Feature Summary
- Straight orientation design for direct board-to-board interconnection
- Through-hole mounting configuration for secure PCB attachment
- Polybutylene terephthalate housing material for structural integrity
Applications
- Automotive body electronics
- Communications equipment
- General industrial control systems
Procurement Notes
Verify the specific suffix codes against the manufacturer's official naming convention to ensure correct pin count and termination style. Confirm that the 250VAC/DC rating aligns with your system's electrical requirements. Check for availability of bulk packaging options if high-volume production is planned. Ensure compatibility with mating headers regarding pitch and row configuration.
Selection Notes
Select this component when a 21-position straight header is required for low-voltage signal transmission. The 2.54mm pitch is standard for general-purpose PCB layouts. Consider the 3A current rating per contact for power distribution needs within these limits. Verify that the through-hole process fits your assembly capabilities and that the operating temperature range meets environmental specifications.
Part Context
This part belongs to the AW140 series of pin receptacles and headers. The series offers various position counts and configurations for board-to-board applications. Assmann WSW Components specializes in IC sockets and IDC connectors, but this specific model is a rigid PCB header designed for stable mechanical connection in electronic assemblies.
Replacement Considerations
Compatible substitutes include other 21-position, 2.54mm pitch straight headers from manufacturers like Molex or TE Connectivity. Ensure the replacement matches the 3A current rating and 250V voltage specification. Verify that the housing material and terminal plating are equivalent to maintain reliability.
