Overview
The AW140-EG-Z28D is a 28-position pin header connector manufactured by Assmann WSW Components. It features a single row of straight pins with a 0.100-inch (2.54mm) pitch, designed for through-hole mounting on printed circuit boards. The contacts are gold-plated to ensure reliable conductivity and corrosion resistance. Rated for 3A current and 250VAC/DC voltage, this component utilizes a polybutylene terephthalate (PBT) housing reinforced with glass fiber. It operates within a temperature range of -55°C to 105°C and meets UL94 V-0 flammability standards.
Feature Summary
- Gold-plated contacts provide durable electrical connectivity and oxidation resistance.
- Straight pin configuration facilitates standard vertical PCB integration.
- Glass-fiber reinforced PBT housing ensures structural stability and thermal resilience.
Applications
- General-purpose electronic circuit interconnections
- Industrial control system board-to-board connections
- Consumer electronics assembly
Procurement Notes
Verify the specific contact plating thickness and material composition against the official datasheet before finalizing procurement decisions. Confirm that the through-hole footprint dimensions align precisely with the target PCB layout to ensure proper mechanical fit and solder joint integrity during assembly processes.
Selection Notes
Select this model when a single-row, straight-pin header is required for high-current applications up to 3A. Ensure the operating environment stays within the specified -55°C to 105°C range. Verify compatibility with mating sockets regarding pin count and pitch to prevent connection failures.
Part Context
This component belongs to the AW140 series of connectors from Assmann WSW Components. The series offers various pin counts and configurations, all sharing consistent 2.54mm pitch specifications. This specific variant provides a robust solution for applications requiring reliable signal or power transmission in compact spaces.
Replacement Considerations
Compatible substitutes include other 28-position, 2.54mm pitch pin headers from manufacturers such as Mill-Max or On Shore Technology. Ensure replacement parts match the current rating, voltage rating, and physical dimensions to maintain system functionality.
