AW140-EG-G31D

Overview

The AW140-EG-G31D is a single-row pin header connector from the AW140 series manufactured by Assmann WSW Components. It features 31 positions with a 2.54 mm (0.100 inch) pitch, designed for board-to-board connections. The component supports a current rating of 3A per contact and a voltage rating of 250V AC/DC. Constructed with brass contacts plated in gold and a PBT housing, it utilizes through-hole termination for secure PCB mounting. The operating temperature range spans from -40°C to 105°C.

Feature Summary

• Single-row configuration with 31 positions for standardized interconnects
• Gold-plated brass contacts ensure reliable signal transmission
• PBT insulation material provides structural stability
• Through-hole termination facilitates direct PCB integration

Applications

• Automotive body electronics and lighting systems
• Communications equipment modules
• Datacom module interconnections
• Personal electronics assemblies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact pin count and plating specifications. Ensure compatibility with mating socket connectors regarding pitch and row configuration. Confirm that the through-hole termination style aligns with the target printed circuit board layout and manufacturing processes before finalizing procurement orders.

Selection Notes

Select this component when a single-row header with 31 positions is required for board-to-board applications. The 2.54 mm pitch is standard for general-purpose interconnects. Consider the 3A current rating and 250V voltage limits to ensure electrical safety within the system design. Verify that the through-hole mounting method suits the assembly requirements and mechanical constraints of the enclosure.

Part Context

This part belongs to the AW140 series of pin headers from Assmann WSW Components. The series offers various position counts while maintaining consistent 2.54 mm pitch and electrical ratings. The AW140 line is designed for reliable performance in automotive, communications, and datacom sectors, providing standardized solutions for board-to-board connectivity needs across multiple electronic product categories.

Replacement Considerations

AW140-EG-G36D is a confirmed substitute offering identical specifications with 36 positions instead of 31. AW140-EG-Z31D serves as an alternative variant within the same series. Verify physical dimensions and pin alignment when substituting to ensure proper fitment in existing designs without modifying the host board footprint.
