Engineering Selection Recommendations
The PEM2-S12-S5-D is obsolete and requires replacement with an active equivalent. Both PEME2-12-S5-D and PEME2-S12-S5-S from CUI Inc. are active and maintain compliance with RoHS and REACH requirements. Substitute models provide matching electrical characteristics, mounting formats, and isolation ratings. Certification differences must be addressed according to user application requirements as provided. When selecting based on package, ensure compatibility with the existing PCB footprint and lead count as per the provided parameters.
Frequently Asked Questions (FAQ)
Q1: What are the critical parameters for substituting the PEM2-S12-S5-D?
A1: Substitute selection is based on input voltage range, output voltage/current, power rating, isolation voltage, mounting type, package/case format, RoHS compliance, and application category.
Q2: Are package differences important when using substitutes?
