Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact pinout configuration and lead spread options. Ensure compliance requirements such as UL recognition or VDE approval status are confirmed for the specific batch. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a single-channel transistor output is required with high isolation voltage. Consider the low input current specification for power-sensitive applications. Verify that the DIP-4 package fits the available PCB space and that the operating temperature range meets environmental conditions.
Part Context
This part belongs to the SFH618A series of low input current phototransistor optically coupled isolators. The series includes variants with different suffixes indicating package type (e.g., G for 10mm lead spread, SM for surface mount). It is manufactured by Isocom Components and shares core architectural features with other members of the SFH family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Users should consult official manufacturer cross-reference lists or datasheets for verified equivalents.
