Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2761B-1-V-F3-K-A directly replace the discontinued CEL PS2761B-1-V-F3-K-A?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Direct substitution is supported without circuit modification or performance degradation.

Q: What are the critical parameters that define substitution compatibility for this optoisolator?

A: Substitution compatibility is determined by: isolation voltage (3750Vrms), single-channel configuration, transistor output type, current transfer ratio (200-400% @ 5mA), maximum output voltage (70V), output current (40mA), Vce saturation (300mV maximum), switching times (4µs rise, 5µs fall), and 4-SOP surface mount package type.

Q: Are there packaging differences between the CEL and Renesas versions?

A: No. Both versions use identical 4-SMD, Gull Wing package configuration (4-SOP supplier device package) for surface mount assembly.

Q: Do both versions meet the same regulatory requirements?

A: Yes. Both the CEL and Renesas versions are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the moisture sensitivity level for this component?

A: Both versions carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during handling, storage, or assembly.

Q: Is the current transfer ratio specification identical between both versions?

A: Yes. Both versions specify a current transfer ratio of 200% minimum to 400% maximum at 5mA input current.

Q: Can this optoisolator be used in high-temperature applications?

A: Yes. The operating temperature range of -55°C to 110°C supports both industrial and extended temperature applications.
