Engineering Selection Recommendations

SCWN03C-15 (MEAN WELL USA Inc.)

The SCWN03C-15 is the direct successor to the SCW03C-15 within the MEAN WELL product family. This part maintains identical electrical specifications for input voltage range (36V - 72V), output voltage (15V), output current (200mA), and power rating (3W). The SCWN03C-15 is classified as Active product status, ensuring ongoing availability and manufacturer support. Enhanced specifications include increased isolation voltage (3 kV versus 1 kV), improved efficiency (87% versus 82%), extended operating temperature range (-40°C to 90°C versus -40°C to 71°C), and additional UVLO (Under-Voltage Lockout) protection. Physical dimensions are compatible with identical mounting footprint and 24-DIP, 8-lead package configuration. RoHS3 compliance and REACH Unaffected status are maintained. This part is recommended as the primary replacement for obsolete SCW03C-15 applications.
