AW140-EG-Z31C1

Overview

The AW140-EG-Z31C1 is a 31-position board-to-board connector header from the AW140 series by Assmann WSW Components. It features a 2.54 mm (0.100 inch) pin spacing and utilizes a single row of straight pins designed for through-hole mounting. The component is constructed with a polybutylene terephthalate (PBT) housing and supports a voltage rating of 250V with a current capacity of 3A. This unshrouded header provides reliable electrical interconnection for printed circuit boards.

Feature Summary

• Single row configuration with straight orientation for direct vertical board stacking
• Through-hole termination method ensuring secure mechanical attachment to the PCB
• Polybutylene terephthalate housing material offering structural stability

Applications

• Automotive body electronics and lighting systems
• Communications equipment signal routing
• Datacom module interconnections
• Personal electronics internal circuitry

Procurement Notes

Verify the specific suffix 'Z' against the manufacturer's official datasheet to confirm plating specifications and contact material composition. Ensure the selected variant matches the required through-hole footprint dimensions and pitch tolerance for the target PCB design. Cross-reference the part number with the latest assembly drawings to validate compatibility with mating connectors in the AW140 series.

Selection Notes

Select this component when a single-row, unshrouded header with 2.54mm pitch is required for through-hole applications. Consider the 3A current rating and 250V voltage limit for circuit requirements. Verify that the straight pin orientation aligns with the mechanical constraints of the board stack-up. Confirm that the PBT housing material meets the thermal and environmental standards of the intended operating environment.

Part Context

This part belongs to the AW140 series, a line of standard board-to-board connectors manufactured by Assmann WSW Components. The series offers various position counts and orientations, providing modular solutions for electronic assemblies. The AW140-EG-Z31C1 specifically addresses needs for 31-pin interconnects within automotive, communications, and datacom sectors.

Replacement Considerations

Compatible substitutes include other AW140 series headers with identical 31-position counts and 2.54mm pitch, such as AW140-EG-G31C1 or AW140-EG-Z31C1 variants from the same manufacturer family, provided pin plating and housing color codes match the design requirements.
