Equivalent & Substitute Parts for Vishay VS-30CPU04PBF
Part Overview
The Vishay VS-30CPU04PBF is a diode array rectifier with a 1 Pair Common Cathode configuration, designed for general-purpose fast recovery applications. Its maximum reverse voltage is 400 V, and it supports an average rectified current of 15A per diode. The device features a fast reverse recovery time, operates in a TO-247-3 package (TO-247AC), and is compliant with ROHS3 and REACH standards. The VS-30CPU04PBF has an obsolete part status, making the identification and selection of alternative models necessary to ensure design continuity and ongoing component availability.

Substitute Part Grouping Explanation
Selections of substitute parts are based solely on matching key electrical and mechanical parameters: diode configuration, maximum reverse voltage, average rectified current, forward voltage at rated current, reverse recovery time, reverse leakage current, operating junction temperature, mounting type, and package type. Only parts that match these criteria are considered equivalent substitutes. Compliance with ROHS3, REACH, and MSL ratings is also required for substitution within regulated supply chains.

Engineering Selection Recommendations
The VS-30CPU04PBF is obsolete. The VS-30CPU04-N3 is active and maintains identical electrical and mechanical parameters, compliance status (ROHS3, REACH), MSL rating, and package type, thereby fulfilling all necessary criteria for substitution within existing designs and supply chains.
Frequently Asked Questions (FAQ)
Q: What criteria must be met for a VS-30CPU04PBF substitute?
A: Substitute parts must have identical diode configuration, maximum reverse voltage, average rectified current, forward voltage at rated current, reverse recovery time, reverse leakage current, operating junction temperature, mounting type, and package.
Q: Is the package or footprint different for the substitute?
A: No, both parts share the TO-247-3 (TO-247AC) package with through-hole mounting.
Q: Are there any compliance considerations in substitution?
A: Both devices are ROHS3 compliant and REACH unaffected, with an unlimited moisture sensitivity level (MSL 1).
Q: How does the reverse recovery time affect substitution?
A: The substitute’s reverse recovery time is within the required specification (≤ 500 ns) and is equal to or faster than the original part.
Q: Is the substitute part currently available?
A: Yes, the VS-30CPU04-N3 is active and listed as in stock.
Q: Do the alternate and main parts originate from the same manufacturer and product series?
A: Yes, both are from Vishay General Semiconductor - Diodes Division and are part of the FRED Pt® series.
