AW140-EA-Z25J

Overview

The AW140-EA-Z25J is a single-row pin header connector from the AW140 series manufactured by Assmann WSW Components. It features 25 positions with a 2.54 mm (0.100 inch) pitch. Designed for through-hole mounting, this right-angle connector utilizes gold-plated brass contacts to ensure reliable signal transmission. The housing is constructed from polybutylene terephthalate (PBT), providing structural integrity and thermal stability. Rated for 3 A current and 250 V voltage, it operates within a temperature range of -40°C to +105°C. This component facilitates board-to-board connections in electronic assemblies requiring robust mechanical retention.

Feature Summary

• Right-angle orientation enables compact vertical board stacking
• Gold-plated contacts provide corrosion resistance and low contact impedance
• Through-hole termination ensures secure mechanical anchoring on PCBs

Applications

• Board-to-board interconnects in industrial control systems
• Signal routing in telecommunications equipment
• Internal connections within consumer electronics enclosures

Procurement Notes

Verify that the specific part number AW140-EA-Z25J matches the required 25-position count and right-angle configuration before ordering. Confirm that the supplier provides original manufacturer documentation to guarantee authenticity. Ensure compatibility with mating sockets regarding pitch and housing dimensions. Check for any specific RoHS or REACH compliance certificates if required by your manufacturing standards. Validate that the through-hole footprint aligns with your PCB design specifications.

Selection Notes

Select this connector when a right-angle profile is necessary to save horizontal space in dense assemblies. The 2.54 mm pitch is standard for general-purpose signaling, ensuring broad availability of mating components. Consider the PBT material properties for environments requiring moderate heat resistance up to 105°C. The gold plating is suitable for applications where frequent mating cycles or high reliability are prioritized over cost savings associated with tin plating.

Part Context

This component belongs to the AW140 series, which offers various position counts and orientations. Similar variants include the AW140-EA-G36G and AW140-EG-G36C1, differing in pin count and straight versus right-angle configurations. The series is designed for general-purpose PCB interconnections, providing a standardized solution for manufacturers needing reliable through-hole headers.
