AW140-EG-Z39C1

Overview

The AW140-EG-Z39C1 is a 39-position pin header connector from the AW140 series by Assmann WSW Components. It features a 2.54 mm pitch and is designed for through-hole mounting in a straight orientation. The connector utilizes a single row configuration with gold flash plating on the contacts to ensure reliable signal transmission. Constructed with polybutylene terephthalate (PBT) housing, it supports a voltage rating of 250V and a current capacity of 3A. This component is engineered for secure board-to-board or cable-to-board interconnections in electronic assemblies requiring robust mechanical stability and electrical performance.

Feature Summary

• Single row straight pin header design for standard PCB mounting
• Gold flash contact plating for enhanced conductivity and corrosion resistance
• Polybutylene terephthalate (PBT) housing material for thermal stability
• Through-hole termination method ensuring secure mechanical attachment

Applications

• Board-to-board interconnection systems
• General purpose electronic circuit boards
• Industrial control equipment interfaces
• Consumer electronics internal wiring

Procurement Notes

Verify the exact position count matches the '39' designation in the part number suffix. Confirm that the 'Z' suffix indicates the specific housing color or variant required for your assembly. Ensure the through-hole footprint on the target PCB aligns with the 2.54 mm pitch specifications. Check for any specific RoHS compliance requirements if operating in regulated markets. Validate that the straight orientation fits within the mechanical constraints of the final enclosure design.

Selection Notes

Select this component when a 39-pin straight header is required for high-reliability connections. The 2.54 mm pitch is standard for general electronics, ensuring compatibility with common ribbon cables and mating connectors. Consider the 3A current rating for power distribution needs within the circuit. The PBT material offers good chemical resistance, making it suitable for various environmental conditions. Ensure the gold plating meets the specific contact resistance requirements of the application.

Part Context

This part belongs to the AW140 series, which is a widely used line of pin headers from Assmann WSW. The series is known for its versatility in providing stable connections across various electronic applications. The AW140 series typically offers multiple position counts and orientations, allowing designers to choose the optimal configuration for their specific PCB layout and connectivity needs.

Replacement Considerations

Direct substitutes may include other 39-position, 2.54 mm pitch pin headers from manufacturers such as Molex or Samtec, provided they match the straight orientation and through-hole mounting style. Verify that alternative parts maintain the same 250V/3A ratings and PBT housing material to ensure equivalent performance and fit.
