Overview
The AW140-EA-Z40J is a single-row pin header connector from the AW140 series by Assmann WSW Components. It features a 2.54 mm pitch and contains 40 positions. Designed for board-to-board connections, this component utilizes through-hole termination for secure PCB mounting. The housing is constructed from polybutylene terephthalate (PBT), providing structural integrity. Electrical specifications include a current rating of 3 A and a voltage rating of 250 V. The contacts are made of brass with gold plating to ensure reliable conductivity. The connector operates within a temperature range of -40°C to +105°C.
Feature Summary
- Single row configuration with right-angle orientation for space-efficient board stacking
- Gold-plated brass contacts ensure durable electrical performance
- Polybutylene terephthalate (PBT) housing provides thermal stability
Applications
- Board-to-board interconnects in industrial control systems
- Signal routing in consumer electronics assemblies
- Connection points in automotive electronic modules
Procurement Notes
Verify the specific suffix 'Z40J' against the manufacturer's official datasheet to confirm exact pin length and mating height requirements. Ensure the ordering part number matches the required contact count and orientation. Cross-reference the material specification to confirm PBT housing compatibility with your assembly process temperatures.
Selection Notes
Select this model when a 40-position right-angle header is required for rigid board-to-board applications. Consider the 2.54 mm pitch standard for compatibility with existing mating connectors. Evaluate the through-hole mounting style against surface-mount alternatives if mechanical stress resistance is critical. Confirm that the 3 A current rating meets the circuit load requirements.
Part Context
This component belongs to the AW140 series, which offers various pin counts and orientations. The AW140 line is designed for general-purpose connectivity needs. Similar models in the series may differ in pin count or angle but share common electrical ratings and housing materials. This specific variant addresses high-density connection requirements.
Replacement Considerations
Compatible substitutes include other 40-pin right-angle headers with 2.54 mm pitch from Assmann WSW, such as AW140-EA-G40G. Verify mechanical dimensions and contact plating before substitution.
