Substitute Part Grouping Explanation

Eligible substitute selection for DC-DC converter products is determined strictly by matching electrical and mechanical parameters. Substitutability is confirmed based on:

• Input voltage range
• Output voltage and output current
• Maximum power rating
• Electrical isolation rating
• Operating temperature range
• Mechanical mounting type and package/case dimensions
• Application suitability
• Features (OCP, OTP, OVP, SCP)
• Compliance (RoHS, REACH) No additional parameters outside those provided have been included.
