SCW05B-09 Equivalent & Substitute Parts Reference

Part Overview

The MEAN WELL USA Inc. SCW05B-09 is a DC DC converter in the Isolated Module category. It is rated for 5 W output with a single 9V output at up to 556mA, accepting input voltages between 18V and 36V. The part features a 1 kV isolation voltage and includes protection features such as overcurrent protection (OCP) and short circuit protection (SCP). The module is through-hole mounted in a 24-DIP package (8 leads) and is RoHS3 compliant.
As the SCW05B-09 is classified as Obsolete, evaluation of compatible and equivalent substitute parts is required for continued design-in and manufacturing continuity.
