Overview
The AW140-EG-Z21D is a board-to-board connector from the AW140 series, manufactured by ASSMANN WSW Components. It features 21 contacts arranged in a single row with a 2.54 mm pitch. Designed for through-hole mounting, this straight pin socket supports a voltage rating of 250V and a current capacity of 3A. The housing utilizes polybutylene terephthalate material, while contacts are constructed from brass with tin plating to ensure reliable signal transmission.
Feature Summary
- Single-row configuration providing compact vertical interconnection
- Through-hole termination method for secure PCB attachment
- Polybutylene terephthalate housing for structural stability
Applications
- Automotive body electronics systems
- Communications equipment modules
- Datacom interface connections
- Personal electronic devices
Procurement Notes
Verify the specific contact plating finish against project requirements, as suffix variations may indicate different surface treatments. Confirm that the standard packaging aligns with assembly line handling protocols. Ensure the through-hole footprint matches the target PCB design specifications before finalizing procurement orders.
Selection Notes
Select this component when a single-row, 21-position vertical interconnect is required at a 2.54 mm pitch. The 3A current rating and 250V specification suit general-purpose digital and low-power analog signals. Consider the straight orientation for space-constrained vertical stacking applications within the AW140 ecosystem.
Part Context
This part belongs to the AW140 series of board-to-board connectors, which offers various contact counts and orientations. The series is characterized by its 2.54 mm pitch and robust construction suitable for industrial and consumer electronics. The AW140-EG-Z21D specifically provides a 21-contact solution for direct board-to-board connectivity.
Replacement Considerations
Cross-reference with other AW140 series variants such as AW140-EG-G21D or AW140-EG-G36B if contact count or plating differences are acceptable. Verify mechanical compatibility with mating headers before substituting, as housing dimensions must remain consistent across the series.
