Equivalent & Substitute Parts Reference: RAC03-3.3SC

Part Overview

The RAC03-3.3SC from Recom Power is an enclosed AC/DC converter, delivering 3.3V output at a maximum 900mA current and 3W rated power. It has a universal AC input range of 90 ~ 264 VAC, with through-hole mounting in a 16-DIP module package. This part is currently marked as obsolete, making it necessary for engineers to seek alternative or equivalent models that match the specified electrical and mechanical parameters for ongoing designs and maintenance requirements.

Engineering Selection Recommendations

Selection among substitute parts is governed by product status and regulatory compliance. RAC03-3.3SC is obsolete, while RAC03E-3.3SK/277 is active and meets ROHS3 and REACH compliance. Substitute parts also carry relevant agency approvals (CB, CE, cURus, EAC) suitable for ITE (Commercial) applications.

Frequently Asked Questions (FAQ)

Q: What are the critical electrical parameters for substituting RAC03-3.3SC?
A: Output voltage (3.3V), output current (900mA), power rating (3W), and input voltage compatibility are critical for substitution.

Q: Are substitute models compatible with the same mounting and packaging?
A: Substitute parts provide through-hole mounting and enclosed module packaging as specified, but detailed mechanical compatibility (such as lead arrangement) should be confirmed per the package/case field.

Q: Do substitutes maintain the same operating temperature range and efficiency?
A: Substitute parts listed operate within the defined temperature range and may offer improved efficiency.

Q: What certifications and compliance should be checked?
A: Relevant approval agencies (CE, EN, UL, CB, cURus, EAC) and RoHS compliance are stated. These are necessary for use in ITE (Commercial) applications as specified.

Q: Is the substitute product actively supported and available?
A: Substitute RAC03E-3.3SK/277 is listed as an active product in stock, whereas RAC03-3.3SC is obsolete.
