Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on parametric equivalence, ensuring matching key parameters: input voltage range, output voltage, maximum output current, number of outputs, total power rating, mounting type, package style, regulatory approvals, RoHS/REACH compliance, and thermal specification. Only parts meeting these criteria are classified as equivalent or substitutes. The substitute listed here, RAC04-3.3SC/277 from Recom Power, is parametric equivalent in all specified fields.

Parameter Comparison

Engineering Selection Recommendations

The RAC04-3.3SC/277 is classified as "Not For New Designs," necessitating evaluation of available inventory and compliance requirements. When selecting an equivalent or substitute, ensure product and environmental compliance are maintained, including RoHS3 and REACH status, and that necessary certification requirements such as CE, EN, and UL approvals are present. Substitute selection is restricted to parts that provide full parametric and regulatory equivalence as detailed above.

Frequently Asked Questions (FAQ)

Q: What criteria determine if a part is parametric equivalent to the RAC04-3.3SC/277?
A: Parametric equivalence is established by matching input voltage range, output voltage and current, number of outputs, power rating, package style, mounting type, regulatory approvals, RoHS/REACH status, and operating temperature.

Q: Is the substitute RAC04-3.3SC/277 compatible in form, fit, and function?
A: The substitute RAC04-3.3SC/277 is fully compatible in form, fit, and function based strictly on the provided matching parameters.

Q: Are there any differences between the main part and the substitute?
A: There are no differences; the main part and the substitute are parametric equivalents with matching technical specifications and compliance attributes.

Q: What packaging and mounting considerations are relevant for replacement?
A: Both the main part and the substitute are supplied in the 7-DIP module, 6 leads, for through-hole mounting, ensuring direct replacement without changes to PCB layout or assembly.

Q: How do regulatory approvals impact substitute selection?
A: Substitute parts must have matching regulatory approvals (CE, EN, UL) and compliance statuses (RoHS3, REACH) to ensure continued certification of end products.
