| FFF Compatibility | Both parts utilize the TO-247 package with identical pin assignments (Anode 1 - Pin 1, Common Cathode - Pin 2/Tab, Anode 2 - Pin 3) making it a direct drop-in.Both parts are standard through-hole TO-247 packages with nearly identical physical outline dimensions.The maximum junction operating temperature is slightly lower at 125°C compared to the original part's 150°C. | Both parts utilize the TO-247 package with identical pin assignments (Anode 1 - Pin 1, Common Cathode - Pin 2/Tab, Anode 2 - Pin 3).Both parts use a standard through-hole TO-247 package style with matching mechanical dimensions.The maximum forward voltage drop (Vf) is slightly higher at 440 mV compared to 420 mV on the original. | ||
 AI Summary | MBR4015LWTG by onsemi: Diode Array 1 Pair Common Cathode 15 V 20A Through Hole TO-247-3. | The STPS40L15CW is an excellent high-performance alternative that provides an identical 15 V reverse voltage and 20 A per diode current rating in the same TO-247-3 package. It features an ultra-low forward voltage drop of 410 mV, which is slightly better than the original part's 420 mV, making it extremely efficient for low-voltage power supply rectification. However, it trades off with a lower maximum operating junction temperature of 125°C instead of 150°C.
| The DSSK40-0015B from IXYS matches the exact physical TO-247-3 package and pin configuration while fully preserving the original part's junction operating temperature range up to 150°C. It serves as a highly robust active alternative with matching voltage and current ratings. The primary trade-offs are a slightly higher forward voltage drop of 440 mV and increased reverse leakage current.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The onsemi MBR4015LWTG is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the onsemi MBR4015LWTG are the STPS40L15CW (STMicroelectronics) and the DSSK40-0015B (IXYS), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the MBR4015LWTG are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The MBR4015LWTG (onsemi) is a part in the Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
