AW140-EA-Z03H

Overview

The AW140-EA-Z03H 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 three contacts designed for board-to-board connections. The component utilizes brass terminals with gold plating and a polybutylene terephthalate housing. Rated for 3 A current and 250 V voltage, it supports through-hole mounting with solder termination. The unit operates within a temperature range of -40°C to 105°C.

Feature Summary

• Single row configuration with right-angle orientation for space-efficient PCB layout
• Gold-plated brass contacts ensure reliable conductivity and corrosion resistance
• Polybutylene terephthalate housing provides structural stability and thermal endurance

Applications

• Board-to-board interconnections in compact electronic assemblies
• Signal routing in industrial control modules
• Connection interfaces in consumer electronics hardware

Procurement Notes

Verify the specific part number suffix to confirm contact count and orientation, as variations exist within the AW140 series. Ensure compatibility with mating female headers regarding pin length and pitch. Confirm that the through-hole soldering process aligns with your manufacturing capabilities and thermal profiles. Cross-reference the voltage and current ratings against your circuit requirements to guarantee safe operation under load conditions.

Selection Notes

Select this model when a low-profile, right-angle single-row connection is required for three signal lines. The 2.54 mm pitch ensures compatibility with standard PCB spacing. Consider the operating temperature range and material composition if the application involves high heat or harsh environments. Validate mechanical fit against the target PCB thickness and mating connector dimensions before finalizing the design.

Part Context

This component belongs to the AW140 series, which offers various configurations including different pin counts and orientations. The series is designed for general-purpose electronic interconnects, providing a balance of electrical performance and mechanical durability. Other variants in the family share similar material properties and rating specifications but differ in physical dimensions and contact quantity.

Replacement Considerations

Direct substitutes may include other 3-pin, 2.54 mm pitch right-angle headers from different manufacturers. Ensure the replacement matches the terminal plating, housing material, and current rating. Verify that the mounting hole dimensions and pin lengths are compatible with the existing PCB footprint to avoid assembly issues.
