AW140-EG-Z03E

Overview

The AW140-EG-Z03E 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 positions for board-to-board connections. The component utilizes brass contacts with gold plating to ensure reliable signal transmission. Designed for through-hole mounting, it operates within a temperature range of -40°C to +105°C and supports a voltage rating of 250V and current capacity of 3A. The housing is constructed from polybutylene terephthalate (PBT), providing structural integrity without an integrated cover.

Feature Summary

• Single-row configuration with 2.54 mm pitch for standard board spacing
• Gold-plated brass contacts for corrosion resistance and conductivity
• Through-hole termination suitable for wave or manual soldering

Applications

• Automotive body electronics and lighting systems
• Communications equipment interconnects
• Datacom module connections
• Personal electronics assemblies

Procurement Notes

Verify the exact pin count against the specific suffix code, as the Z03E designation indicates a three-position variant distinct from other lengths in the AW140 series. Confirm that the through-hole tail length matches the target PCB thickness requirements. Ensure compatibility with mating headers regarding contact type and row alignment before finalizing procurement specifications.

Selection Notes

Select this component when a short, three-position connection is required between adjacent boards. The straight orientation suits vertical stacking applications where space above the board is available. Consider the PBT material properties for thermal stability during soldering processes. Verify that the 3A current rating meets the electrical load requirements of the specific circuit design.

Part Context

This part belongs to the AW140 series of board-to-board connectors, which offers various pin counts and tail lengths. The AW140-EG-Z03E specifically denotes a three-position header with a standard straight profile. It complements longer variants like the 36-pin models by providing options for compact, low-density interconnections within the same mechanical footprint and material specification family.

Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, 3-position count, and through-hole mounting style. Verify that alternative manufacturers offer compatible gold-plated brass contacts and PBT housings. Ensure the mating header specifications align with the contact dimensions to maintain reliable electrical performance.
