Overview
The AW140-EA-Z38J is a single-row male pin header from the AW140 series, manufactured by Assmann WSW Components. Designed for board-to-board connections, this connector features a 2.54 mm pitch and accommodates 38 contacts. It utilizes brass contacts with gold plating housed in a Polybutylene Terephthalate (PBT) insulator. The component supports through-hole termination and operates within a temperature range of -40°C to 105°C at a rated voltage of 250V and current of 3A.
Feature Summary
- Single-row configuration with 38 positions for high-density interconnects
- Gold-plated brass contacts ensure reliable signal transmission
- Right-angle orientation facilitates compact PCB layout integration
Applications
- Industrial control system circuit boards
- Data center server backplanes
- Aerospace avionics modules
- Consumer electronics internal interfaces
Procurement Notes
Verify the specific suffix 'Z' against manufacturer documentation to confirm material specifications, as ordering codes may denote variations in insulation or contact plating. Ensure compatibility with mating connectors regarding pin length and housing dimensions. Cross-reference official datasheets for precise mechanical tolerances before finalizing procurement orders.
Selection Notes
Select this model when a right-angle, single-row header with 38 pins is required. Confirm that the 2.54 mm pitch aligns with the target PCB footprint. Verify that the PBT insulation and gold plating meet environmental and conductivity requirements for the intended application environment.
Part Context
This component belongs to the AW140 series of board-to-board connectors. The series offers various configurations including straight and right-angle options with different pin counts. The AW140-EA-Z38J specifically addresses needs for right-angle mounting with a higher pin density compared to lower-count variants in the same family.
Replacement Considerations
Compatible substitutes include AW140-EA-G38H and AW140-EA-Z38H. These alternatives share the same 38-position count, 2.54 mm pitch, and right-angle form factor. Verify that the suffix differences do not alter critical electrical or mechanical parameters before substitution.
