Procurement Notes
Verify component status before procurement as this series is officially obsolete and not recommended for new designs. Confirm availability through authorized distributors or secondary markets. Evaluate recommended replacement products provided by the manufacturer to ensure long-term supply chain stability and compliance with current design standards.
Selection Notes
Select this component only for legacy system maintenance or repair where original specifications are mandatory. For new designs, utilize the manufacturer's recommended replacement products instead. Ensure application requirements align with the 400 V reverse voltage rating and 3.0 A forward current capacity within the specified thermal operating range.
Part Context
This part belongs to the CD214B-R350~R31000 series of glass passivated rectifiers. These components are designed for compact PCB real estate savings compared to competitive parts. The series conforms to JEDEC standards and utilizes a flat configuration to minimize roll-away during standard pick-and-place assembly processes.
Replacement Considerations
The datasheet explicitly states the product is obsolete and recommends replacement products are available. Consult official Bourns documentation for specific substitute part numbers suitable for new designs.
