AW140-EG-G31B

Overview

The AW140-EG-G31B is a single-row male pin header connector from the AW140 series by Assmann WSW Components. It features a 2.54 mm pitch and supports 31 positions with a rated current of 3A and voltage of 250V. Constructed with brass contacts gold-plated for conductivity, the housing utilizes polybutylene terephthalate (PBT). Designed for through-hole mounting on board-to-board applications, it operates within a temperature range of -40°C to +105°C.

Feature Summary

• Single-row straight male pin configuration for direct PCB insertion
• Gold-plated brass contacts ensure reliable signal transmission
• Polybutylene terephthalate housing provides thermal stability

Applications

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

Procurement Notes

Verify the specific contact tail length and mating pin height requirements against your PCB design constraints before ordering. Confirm that the 31-position count matches the target circuit interface. Ensure the through-hole footprint aligns with standard 2.54 mm spacing guidelines to guarantee proper solder joint integrity during assembly.

Selection Notes

Select this component when a single-row, 31-pin male header is required for board-to-board connections. The 2.54 mm pitch suits general-purpose digital and low-power analog signals. Consider the AW140 series if high thermal resistance up to 105°C and robust PBT material properties are necessary for the operating environment.

Part Context

This part belongs to the AW140 series, which offers various pin counts and tail lengths. The AW140-EG-G31B specifically addresses needs for 31-channel interfaces. Similar variants exist with different pin counts or tail dimensions, allowing designers to maintain consistent connector families across different product lines while adapting to specific spatial constraints.

Replacement Considerations

Compatible substitutes include other 31-position, 2.54 mm pitch male headers from manufacturers such as Samtec or Molex, provided they match the current rating and mechanical dimensions. Verify that alternative parts support the same through-hole mounting style and compatible mating female connectors.
