AW140-EA-Z17G

Overview

The AW140-EA-Z17G 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 17 positions. Designed for board-to-board applications, this component utilizes through-hole termination for secure PCB mounting. The contacts are constructed from brass with gold plating to ensure reliable conductivity. Rated for 3 A current and 250 V voltage, it operates within a temperature range of -40°C to 105°C. The housing is made of polybutylene terephthalate (PBT), providing structural integrity without an integrated cover.

Feature Summary

• Single-row male pin configuration for direct board-to-board interconnection
• Through-hole solder termination ensures stable mechanical attachment to printed circuit boards
• Gold-plated brass contacts provide durable electrical performance in standard environments

Applications

• Interconnecting daughterboards to main logic boards in compact electronic assemblies
• Signal routing between stacked circuit modules in industrial control systems
• Connection points for peripheral interface expansion in embedded hardware

Procurement Notes

Verify the exact pin count and orientation against the specific design requirement before ordering. Confirm that the target PCB footprint matches the 2.54 mm pitch specifications. Ensure the operating environment remains within the stated thermal limits. Check for any specific surface finish requirements if harsh conditions apply. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Selection Notes

Select this component when a right-angle or straight single-row header is required for low-current signal transmission. Consider the through-hole mounting method if mechanical strength during assembly is prioritized over automated placement speed. Evaluate the 3 A rating against the maximum expected load on each contact line. Verify that the PBT housing material meets the chemical resistance needs of the manufacturing process.

Part Context

This connector belongs to the AW140 series, which offers various pin counts and orientations. The series is designed for general-purpose electronics where reliable interconnectivity is essential. Similar parts in the lineup differ primarily in the number of positions and the physical angle of the pins relative to the board plane.

Replacement Considerations

Compatible substitutes include other 17-position, 2.54 mm pitch headers from different manufacturers provided they match the through-hole termination style and current ratings. Ensure the replacement maintains the same contact plating and housing material properties to preserve environmental resilience.
