Equivalent & Substitute Parts for RAC03-12SC
Part Overview
The RAC03-12SC, produced by Recom Power, is an enclosed AC/DC converter delivering 12V at 250mA output and a maximum power of 3W. It is designed for ITE (Commercial) applications and features universal input voltage compatibility (90 ~ 264 VAC). The product is through-hole mounted and encased in a 16-DIP module. The RAC03-12SC is currently designated as obsolete, necessitating identification of alternative models for continued design-in or replacement purposes when stock is depleted.

Substitute Part Grouping Explanation
Substitute parts are selected based on strict matching of electrical and mechanical parameters as specified. Required criteria include: identical output voltage (12V), equivalent output current capability (250mA), matching total output wattage (3W), through-hole mounting, single-output configuration, compatible mechanical envelope, and compliant regulatory/certification status. Input voltage range must fully enclose the original range with equal or wider limits. Product status and adherence to environmental and agency approvals are considered for continued fit in existing applications.

Engineering Selection Recommendations
RAC03-12SC is obsolete. Substitute RAC03E-12SK/277 incorporates the same electrical output parameters, through-hole mounting, and ROHS3/REACH compliance. Both models are intended for ITE (Commercial) use and provide agency certifications. RAC03E-12SK/277 is listed as active and fully certified.
Frequently Asked Questions (FAQ)
Q: What are the key substitution criteria between RAC03-12SC and RAC03E-12SK/277?
A: Substitute selection is based on output voltage (12V), output current (250mA), total output power (3W), single-output configuration, through-hole mounting, RoHS3/REACH compliance, and compatible agency certifications.
Q: Are mechanical dimensions or package types different?
A: RAC03-12SC uses a 16-DIP Module, 5 Leads; RAC03E-12SK/277 uses a 4-DIP Module. Size is similar but not identical; compatibility should be confirmed based on actual board layout requirements.
Q: Do both parts have comparable regulatory approvals?
A: Both models include multiple agency certifications as indicated in the parameters.
Q: Is there a difference in environmental performance?
A: RAC03E-12SK/277 supports a wider operating temperature range.
Q: What is the product status difference?
A: RAC03-12SC is obsolete. RAC03E-12SK/277 is active.
Q: Are both parts compliant with RoHS and REACH?
A: Both parts are ROHS3 Compliant and REACH Unaffected according to provided parameters.
