Key Parameters

Substitute Part Grouping Explanation

Substitution for the OmniOn Power SC003A5F91Z is performed strictly on parameters that determine electrical and mechanical compatibility. The substitute part, TDK-Lambda Americas Inc PXB15-24S3P3/NT, is selected based on identical input voltage range, output voltage, number of outputs, operating temperature range, mounting type, and package/case format. Features such as remote on/off, overcurrent and overvoltage protection are present in both models. Key substitution parameters used for equivalency are:

• Input Voltage Range (18V – 36V)
• Output Voltage (3.3V)
• Output Current Capability
• Output Power
• Package / Case (6-DIP Module, Through Hole)
• Functional Features
• Operating Temperature Range

Parameter Comparison

Engineering Selection Recommendations

Selection of TDK-Lambda Americas Inc PXB15-24S3P3/NT is based on equivalent input voltage range, output voltage, and matching mechanical form factor. Both products share the same compliance attributes (ECCN EAR99, HTSUS 8504.40.9580, Moisture Sensitivity Level 1), through-hole mounting, and control features. The substitute is RoHS compliant and REACH unaffected. The obsolete status of SC003A5F91Z and the active availability of PXB15-24S3P3/NT provide a direct pathway to substitution based strictly on provided status and documented compliance.
