Selection notes
Match the complete model suffix, rated current and constant-current voltage window. Allow for cold and hot LED-string voltage, temperature derating, dimming compatibility and enclosure conditions. This preliminary comparison is not an isolation, wiring or electrical-safety approval.
Evidence and limits
An omitted parameter is unknown here, not zero. Typical, minimum and maximum values are not interchangeable. A family profile is not an exact electrical configuration and does not automatically qualify for the driver selector.
