AW140-EA-G39J

Overview

The AW140-EA-G39J is a single-row pin header connector from the AW140 series, manufactured by Assmann WSW Components. It features a 2.54 mm pitch and contains 39 positions designed for board-to-board connectivity. The component utilizes brass contacts with gold plating to ensure reliable signal transmission. Rated for 250 V and 3 A, it supports through-hole mounting with a right-angle orientation. The housing is constructed from polybutylene terephthalate (PBT), providing structural integrity across an operating temperature range of -40°C to +105°C.

Feature Summary

• Right-angle configuration facilitates compact vertical interconnections between circuit boards.
• Gold-plated brass contacts provide durable conductivity and corrosion resistance.
• Polybutylene terephthalate housing ensures thermal stability and mechanical strength.

Applications

• Board-to-board interconnection in electronic assemblies
• Signal routing in industrial control systems
• Connection points in consumer electronics hardware

Procurement Notes

Verify the specific part number against manufacturer documentation to confirm physical dimensions and contact configuration. Ensure compatibility with mating socket connectors regarding pitch and row count. Check for required certifications or environmental ratings if the application involves strict regulatory compliance. Confirm that the through-hole footprint matches the target PCB design specifications before finalizing procurement.

Selection Notes

Select this model when a right-angle, single-row connection is required for high-density layouts. The 2.54 mm pitch is standard for general-purpose electronics, ensuring broad availability of mating components. Consider the 3 A current rating and 250 V voltage limit to ensure they meet the circuit requirements. The PBT material selection supports applications requiring moderate thermal resistance.

Part Context

This component belongs to the AW140 series, which offers various configurations including different pin counts and orientations. The AW140 line is designed for versatile through-hole applications, providing options for both straight and right-angle headers. This specific variant focuses on the 39-position capacity, catering to designs needing extensive parallel signal paths within a single row.

Replacement Considerations

Compatible substitutes include other 39-position, 2.54 mm pitch right-angle headers from the same series, such as AW140-EA-G39G or AW140-EA-G39H, provided the tail pin length and housing style match the assembly constraints. Verify that alternative manufacturers offer equivalent electrical ratings and material compositions.
