Engineering Selection Recommendations

VS-30CPU04LHN3 (Direct Manufacturer Equivalent)

This part is the direct equivalent from Vishay General Semiconductor with Active product status. It maintains identical electrical specifications across all critical parameters: 400 V reverse voltage, 15 A average rectified current, 1.25 V forward voltage at 15 A, and 46 ns reverse recovery time. The operating temperature range differs only in minimum junction temperature (-55°C versus -65°C), which does not restrict substitution in applications operating above -55°C. The TO-247AD supplier package designation is mechanically and electrically compatible with TO-247AC. This part is recommended as the primary substitute for obsolete stock replacement.

VS-30CPU04-N3 (Parametric Equivalent)

This Vishay part maintains complete parametric equivalence with the main part, including identical operating temperature range (-65°C ~ 175°C) and reverse recovery time (46 ns). Product status is Active. The TO-247AC supplier package matches the original specification. This part is suitable for direct substitution and offers the highest inventory availability (2000 pcs).

SDUR3040WT (Manufacturer-Recommended Alternative)

This SMC Diode Solutions part meets all mandatory electrical parameters with 400 V reverse voltage, 15 A average rectified current, and 1.25 V forward voltage. Reverse recovery time is 45 ns, within acceptable tolerance. The operating temperature range is -55°C ~ 150°C, which restricts use in applications requiring operation below -55°C or above 150°C. Product status is Active with highest inventory availability (5700 pcs). REACH Status is listed as Affected, requiring compliance verification for regulated applications. This part is suitable for substitution in applications within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can VS-30CPU04LHN3 directly replace VS-30CPU04HN3 in all applications?

A: VS-30CPU04LHN3 is a direct substitute for applications operating at junction temperatures of -55°C and above. The main part specifies -65°C minimum junction temperature; VS-30CPU04LHN3 specifies -55°C minimum. All other electrical parameters are identical. Verify application minimum operating temperature before substitution.

Q: What is the difference between TO-247AC and TO-247AD supplier package designations?

A: Both designations refer to the same TO-247-3 mechanical package. The letter suffix indicates internal lead configuration or manufacturing variant. Both are mechanically and electrically compatible for through-hole mounting applications.

Q: Is SDUR3040WT suitable for automotive applications?

A: The main part VS-30CPU04HN3 carries AEC-Q101 automotive qualification. SDUR3040WT does not list automotive qualification in the provided specifications. Verify automotive compliance requirements before substitution in automotive applications.

Q: What is the significance of the 1 ns difference in reverse recovery time between VS-30CPU04HN3 (46 ns) and SDUR3040WT (45 ns)?

A: The 1 ns difference is within normal manufacturing tolerance and does not affect functional equivalence. Both parts meet the Fast Recovery classification (≤ 500ns, > 200mA). This variation does not restrict substitution.

Q: Why is inventory availability different across substitute parts?

A: Inventory levels reflect current stock status at the time of specification. VS-30CPU04-N3 and SDUR3040WT show higher availability than the obsolete VS-30CPU04HN3. Verify current inventory with suppliers before procurement.

Q: Can these parts be used interchangeably in existing PCB designs?

A: All substitute parts use identical TO-247-3 through-hole package with the same pin configuration and mechanical footprint. PCB designs require no modification. Verify electrical specifications match application requirements before substitution.

Q: What does ROHS3 Compliant status mean for these diode arrays?

A: ROHS3 Compliant indicates conformance to Restriction of Hazardous Substances Directive 3, restricting lead, cadmium, mercury, and other hazardous materials. All listed parts meet this compliance requirement.
