Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RAC03-3.3SA are selected by strict equivalence in input voltage range, output voltage and current, power rating, mounting type, package style, compliance status, and application suitability. The following parameters are considered vital for equivalency: number of outputs, voltage–input, voltage–output, output current, wattage, mounting type, package/case, environmental compliance, and operating temperature.

Parameter Comparison

Engineering Selection Recommendations

The RAC03-3.3SA and RAC03-3.3SC are both obsolete but maintain compliance with ROHS3 and REACH regulations, and both are suitable for ITE (Commercial) environments. Selection among these options should consider regulatory compliance status, certification alignment, and inventory availability as provided. Packaging and form-factor differences can affect compatibility depending on the physical design constraints of the existing application.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting RAC03-3.3SA with RAC03-3.3SC?
A1: Key substitution criteria include identical output voltage and current, input voltage range, power rating, mounting method, environmental compliance, and application suitability.

Q2: Are there any differences in packaging or mechanical layout?
A2: Yes, RAC03-3.3SA uses a 4-SIP Module while RAC03-3.3SC uses a 16-DIP Module, 5 Leads. Mechanical compatibility with the host PCB should be verified based on the given dimensions and package type.

Q3: Do both parts have equivalent regulatory and environmental compliance?
A3: Both RAC03-3.3SA and RAC03-3.3SC are ROHS3 compliant and REACH unaffected.

Q4: Are there efficiency differences to consider?
A4: RAC03-3.3SA has an efficiency of 70%, while RAC03-3.3SC specifies 63%. Power dissipation requirements should be assessed as needed.

Q5: What application categories are covered by these substitutes?
A5: Both models are rated for ITE (Commercial) use.

Q6: Is there a difference in the operating temperature range?
A6: RAC03-3.3SA supports -40°C to 85°C (with derating) while RAC03-3.3SC supports -25°C to 85°C (with derating). System requirements should be matched to these ranges based on application needs.
