Equivalent & Substitute Parts Reference: RAC04-12SA

Part Overview

RAC04-12SA is an enclosed AC/DC converter manufactured by Recom Power, in the POWERLINE RAC04 (4W) series. It offers a single regulated 12V output at 333mA, operates from 90 ~ 264VAC, and is suitable for ITE (commercial) applications with features such as universal input and through-hole mounting. The product status is "Not For New Designs", indicating that engineers should consider qualified alternates for new or sustaining designs requiring equivalent electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitutes for RAC04-12SA are identified using the following explicit parameters: input voltage range, output voltage, maximum output current, total output power, package/case, mounting type, number of outputs, and compliance/certifications. Substitution is allowed only if the alternative part matches or exceeds the main part’s electrical and mechanical specifications within the defined criteria.

Group selection is strictly based on:

• Output Voltage: 12V
• Output Current: 333mA
• Power: 4W
• Input Voltage Range: Minimum must meet or exceed 90 VAC, maximum must equal or exceed 264 VAC
• Package/Case: 7-DIP Module or equivalent form factor
• Mounting Type: Through Hole
• Compliance: RoHS3, relevant certifications

Parameter Comparison

Engineering Selection Recommendations

For legacy designs or inventory management, RAC04-12SA and its substitute RAC04-12SC/277 are both ROHS3 compliant and maintain certification with CE and EN standards. However, neither part is recommended for new designs based on their product status ("Not For New Designs"). Appropriate engineering selection should rely on matching electrical parameters, mechanical form factor, and compliance with application-specific certifications.

Frequently Asked Questions (FAQ)

Q1: What input voltage compatibility should be checked when substituting RAC04-12SA?
A1: The substitute must support an input voltage range that meets or exceeds 90 ~ 264 VAC. RAC04-12SC/277 operates from 80 ~ 305 VAC, which includes and surpasses the original requirement.

Q2: Are mounting and package requirements the same for both models?
A2: Both parts use through-hole mounting and similar 7-DIP module form factors. The substitute has a slight dimensional difference and uses 6 leads.

Q3: Do substitute parts match output performance?
A3: Both supply 12V at a maximum current of 333mA and provide 4W output power.

Q4: Is regulatory compliance equivalent for engineering selection?
A4: Both parts are ROHS3 compliant and carry CE and EN approvals, with the substitute also holding UL certification.

Q5: Should new designs implement these models?
A5: Neither the RAC04-12SA nor RAC04-12SC/277 should be used for new designs due to their indicated product status. Only qualifying legacy designs or inventory replacements are advised within the provided parameter scope.
