Key Parameters

Substitute Part Grouping Explanation

Substitution of the NRVB8H100MFST1G is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 8 A
• Current - Reverse Leakage @ Vr: 2 µA @ 100 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Environmental Specifications:

• Mounting Type: Surface Mount
• Package / Case: 8-PowerTDFN, 5 Leads
• Supplier Device Package: 5-DFN (5x6) (8-SOFL)
• Operating Temperature - Junction: -55°C to 175°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain identical electrical performance and physical form factor compatibility. Differences in product status (active vs. obsolete) and packaging format (Cut Tape vs. Tape & Reel) do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications:

MBR8H100MFST1G is the direct functional equivalent to NRVB8H100MFST1G. Both parts share identical electrical specifications and physical packaging. MBR8H100MFST1G maintains active product status, ensuring continued availability and supply chain support. The primary distinction is packaging format: MBR8H100MFST1G is supplied in Tape & Reel (TR) format, whereas the original part was available in Cut Tape (CT) & Digi-Reel® format. This difference does not affect component performance or PCB assembly compatibility.

For Automotive Applications:

NRVB8H100MFSWFT1G and NRVB8H100MFSWFT3G are automotive-grade equivalents qualified to AEC-Q101 standard. Both parts maintain identical electrical and mechanical specifications while providing automotive-level reliability assurance. NRVB8H100MFSWFT3G offers significantly higher inventory availability (55,100 units) compared to NRVB8H100MFSWFT1G (1,153 units), making it the preferred selection for high-volume automotive procurement.

All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080, maintaining regulatory equivalence with the original part.

Frequently Asked Questions (FAQ)

Q: Can NRVB8H100MFST1G be replaced with MBR8H100MFST1G in existing designs?

A: Yes. MBR8H100MFST1G is electrically and mechanically equivalent. Both devices feature identical voltage ratings (100 V), current ratings (8 A), forward voltage drop (900 mV @ 8 A), reverse leakage (2 µA @ 100 V), and package configuration (5-DFN 5x6). The parts are pin-compatible and functionally interchangeable. MBR8H100MFST1G is currently in active production status, addressing the obsolescence of NRVB8H100MFST1G.

Q: What is the difference between NRVB8H100MFSWFT1G and NRVB8H100MFSWFT3G?

A: Both parts are automotive-grade Schottky diodes with AEC-Q101 qualification. Electrical and mechanical specifications are identical. The primary difference is inventory availability: NRVB8H100MFSWFT3G has substantially higher stock (55,100 units) compared to NRVB8H100MFSWFT1G (1,153 units). For high-volume production, NRVB8H100MFSWFT3G is the preferred selection.

Q: Are automotive-grade parts (NRVB8H100MFSWFT1G, NRVB8H100MFSWFT3G) suitable for non-automotive applications?

A: Yes. Automotive-grade parts exceed standard industrial requirements and are fully compatible with non-automotive applications. AEC-Q101 qualification ensures enhanced reliability margins. These parts can be used as direct replacements in any application requiring the specified electrical and thermal performance.

Q: What is the significance of the packaging format difference (Cut Tape vs. Tape & Reel)?

A: Packaging format affects procurement and assembly logistics but does not impact component performance or electrical characteristics. Cut Tape (CT) & Digi-Reel® format is suitable for manual or small-batch assembly. Tape & Reel (TR) format is optimized for automated high-volume production. Selection depends on manufacturing process requirements, not functional compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (MBR8H100MFST1G, NRVB8H100MFSWFT1G, NRVB8H100MFSWFT3G) are ROHS3 compliant and REACH unaffected, maintaining full regulatory equivalence with NRVB8H100MFST1G.

Q: Can these diodes operate across the full temperature range of -55°C to 175°C?

A: Yes. All substitute parts are rated for junction operating temperatures from -55°C to 175°C. This temperature range applies to all listed equivalents and supports applications requiring extended thermal performance.
