Substitute Part Grouping Explanation

Substitution of the obsolete MBR460MFST3G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts must satisfy the following criteria:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 60 V
• Current - Average Rectified (Io): 4 A
• Voltage - Forward (Vf) (Max) @ If: 740 mV @ 4 A
• Current - Reverse Leakage @ Vr: 200 µA @ 60 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match Exactly):

• Mounting Type: Surface Mount
• Package / Case: 8-PowerTDFN, 5 Leads
• Supplier Device Package: 5-DFN (5x6) (8-SOFL)

Environmental & Compliance Parameters (Must Match Exactly):

• Operating Temperature - Junction: -55°C ~ 175°C
• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The identified substitute parts maintain full parametric equivalence and are classified as active products, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

MBR460MFST1G is the primary substitute for MBR460MFST3G. Both parts are manufactured by onsemi and maintain identical electrical specifications, thermal ratings, and compliance certifications. The MBR460MFST1G is classified as an active product with current production status, ensuring reliable long-term availability. This part is supplied in Tape & Reel (TR) packaging format.

NRVB460MFST1G is an alternative substitute that provides equivalent electrical and mechanical performance. This part is also classified as active and is supplied in Cut Tape (CT) & Digi-Reel® packaging format. The NRVB460MFST1G represents a different base product number within the onsemi portfolio but maintains full parametric equivalence to the obsolete MBR460MFST3G.

Both substitute parts satisfy all electrical, thermal, environmental, and regulatory requirements specified for the original component. Selection between MBR460MFST1G and NRVB460MFST1G is determined by packaging and supply chain requirements rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can MBR460MFST1G be used as a direct replacement for MBR460MFST3G?

A: Yes. MBR460MFST1G is a parametric equivalent with identical electrical ratings (60 V, 4 A), forward voltage characteristics (740 mV @ 4 A), reverse leakage current (200 µA @ 60 V), and package configuration (5-DFN 5x6). Both parts are ROHS3 compliant with MSL 1 rating and operate across the same temperature range (-55°C to 175°C).

Q: What is the difference between MBR460MFST1G and NRVB460MFST1G?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is the base product number designation (MBR460 versus NRVB460) and packaging format. MBR460MFST1G is supplied in Tape & Reel (TR) format, while NRVB460MFST1G is supplied in Cut Tape (CT) & Digi-Reel® format. Electrical performance and package dimensions are identical.

Q: Are the substitute parts available in the same package as the original MBR460MFST3G?

A: Yes. All substitute parts use the 8-PowerTDFN, 5 Leads package with 5-DFN (5x6) (8-SOFL) supplier device package designation. The physical dimensions and pin configuration are identical, enabling direct PCB layout compatibility.

Q: What is the product status of the substitute parts?

A: Both MBR460MFST1G and NRVB460MFST1G are classified as active products with current manufacturing status. The original MBR460MFST3G is obsolete. Active status ensures continued availability and supply chain support.

Q: Do the substitute parts meet the same compliance requirements as the original part?

A: Yes. All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is maintained across all equivalent parts.

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

A: Yes. The substitute parts maintain full electrical, thermal, and mechanical equivalence. No circuit modifications or PCB redesign is required for substitution. The identical package configuration and electrical characteristics ensure functional interchangeability.
