Frequently Asked Questions (FAQ)

Q: Can the NRVB5100MFST1G directly replace the MBR5100MFST3G in existing designs?

A: Yes. The NRVB5100MFST1G is electrically and mechanically equivalent to the MBR5100MFST3G. All critical parameters including voltage rating, current capacity, forward voltage drop, reverse leakage, and package configuration are identical. No circuit modifications are required.

Q: What is the primary difference between these two part numbers?

A: The MBR5100MFST3G is classified as obsolete, while the NRVB5100MFST1G maintains active product status. The NRVB5100MFST1G is supplied in Tape & Reel packaging, whereas the original part number does not specify packaging format. Both parts are manufactured by onsemi and share the same base product number series.

Q: Are there any compliance or certification differences?

A: No. Both the MBR5100MFST3G and NRVB5100MFST1G are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Operating temperature ranges are identical at -55°C to 175°C junction temperature.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: 100 V DC reverse voltage rating, 5 A average rectified current, 980 mV maximum forward voltage at 5 A, 10 µA reverse leakage current at 100 V, and fast recovery speed characteristic (≤ 500ns, > 200mA). All parameters are identical between the two parts.

Q: Is the 5-DFN (5x6) package footprint identical for both parts?

A: Yes. Both components use the 8-PowerTDFN package with 5 leads and the 5-DFN (5x6) (8-SOFL) supplier device package. PCB footprints and land patterns are identical, requiring no layout modifications.
