Key Parameters

Substitute Part Grouping Explanation

Substitute grouping utilizes direct manufacturer recommendations and equivalence in key electrical and mechanical parameters. Substitution is strictly determined by the following criteria:

• Voltage - Input
• Voltage - Output 1
• Number of Outputs
• Output Current
• Power Rating
• Operating Temperature Range
• Package / Case
• Mounting Type
• Regulatory Approvals and RoHS Compliance

These parameters ensure functional compatibility and compliance with regulatory requirements, as well as consistent form factor for physical integration.

Parameter Comparison

Engineering Selection Recommendations

The main part, CUI Inc. PBO-8-12, is marked as obsolete, while the substitute part PBO-15C-12 is active and available.
