Procurement Notes
Verify the specific suffix F3-A against official Renesas documentation to confirm tape and reel packaging specifications. Ensure the component status is reviewed as some sources indicate it may be not recommended for new designs. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and check for recent product change notices regarding labeling or manufacturing location changes.
Selection Notes
Select this component when high isolation voltage and moderate speed are required for signal transmission. The wide operating temperature range supports industrial environments. Compare the current transfer ratio requirements against the 300% to 600% specification to ensure adequate noise margin. Consider the SMD package dimensions for PCB layout constraints and verify compatibility with existing surface mount assembly equipment.
Part Context
This device belongs to the PS2561 family of transistor output optocouplers from Renesas Electronics. The family includes various packages such as DIP and SMD options with different isolation ratings and switching speeds. The FL variant specifically denotes the surface mount configuration with enhanced performance metrics compared to standard versions. This series is widely used in industrial control and consumer electronics for reliable signal isolation.
Replacement Considerations
Publicly confirmed parameter-equivalent substitutes include PS2561FL-1Y-A, PS2561FL-1Y-A-K, PS2561FL-1Y-F3-A, PS2561FL-1Y-F3-A-K, PS2561FL-1Y-K-A, and PS2561FL-1Y-A/K. Verify pinout compatibility and electrical specifications before substitution.
