Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by the following critical parameters: output voltage, number of outputs, input voltage range, mounting type, package/case, output current (where equal or greater), power rating (where equal or greater), compliance certifications, and mechanical compatibility (dimensions and format). Substitute models must meet or exceed the original device’s key specifications for direct replacement in the same application and assembly environment.

Parameter Comparison

Engineering Selection Recommendations

Selection of the substitute part PBO-15C-9-B is based on the primary requirement that the original PBO-8-9-B is obsolete. The PBO-15C-9-B is currently active and carries equivalent or superior compliance certifications, including CE, cURus, and UL, adhering to the same international safety standards (60335-1, 62368-1) and RoHS restrictions. Its performance and mechanical format are compatible with the original part’s application environment.

Frequently Asked Questions (FAQ)

Q1: What are the key substitution criteria for the PBO-8-9-B?
