Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching electrical and mechanical parameters as provided. The functional compatibility relies on the following key parameters:

• Input voltage range (4.5V to 9V)
• Output voltage (3.3V)
• Maximum output current (500mA)
• Isolation voltage (1.5 kV)
• Output power
• Package type and pin-count (8-SIP Module, 7 Leads)
• Operating temperature range
• Feature set (Remote On/Off, OCP, SCP)
• Relevant compliance standards (RoHS, REACH) Only parts explicitly matching these required fields are listed as substitutes.
