MBR8H100MFST1G Equivalent & Substitute Parts

Part Overview

The MBR8H100MFST1G is a Schottky rectifier diode manufactured by onsemi, rated for 100 V DC reverse voltage and 8 A average rectified current. This surface mount component is housed in a 5-DFN (5x6) package and is currently in active product status. Substitute parts become necessary when the primary part number reaches end-of-life status, when packaging formats differ between procurement channels, or when automotive-grade qualification is required for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR8H100MFST1G is determined by electrical and mechanical parameter equivalence. All substitute parts must maintain identical specifications across the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 8 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 8 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 2 µA @ 100 V
• Package / Case: 8-PowerTDFN, 5 Leads
• Supplier Device Package: 5-DFN (5x6) (8-SOFL)
• Operating Temperature - Junction: -55°C ~ 175°C
• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape), product status (Active versus Obsolete), and automotive qualification levels. These differences do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

MBR8H100MFST1G (Primary Part)

This part is the baseline reference component with Active product status. It is suitable for general industrial and commercial applications requiring 100 V, 8 A Schottky rectification in a 5-DFN surface mount package. The part is ROHS3 compliant and carries unlimited moisture sensitivity classification.

NRVB8H100MFST1G (Substitute - Obsolete Status)

This part is electrically and mechanically identical to the primary part but carries Obsolete product status. The primary difference is packaging format: Cut Tape (CT) & Digi-Reel® versus Tape & Reel (TR). This part should be selected only when Cut Tape packaging is required and inventory availability is confirmed. Obsolete status indicates this part number is no longer in active production.

NRVB8H100MFSWFT3G (Substitute - Automotive Grade)

This part is electrically and mechanically identical to the primary part and maintains Active product status. The distinguishing feature is automotive-grade qualification to AEC-Q101 standard. This part is required for automotive applications where AEC-Q101 certification is mandatory. Packaging format is Tape & Reel (TR), matching the primary part. Inventory availability is significantly higher than the primary part.

Frequently Asked Questions (FAQ)

Q: Can NRVB8H100MFST1G be used as a direct replacement for MBR8H100MFST1G?

A: Yes. Both parts are electrically and mechanically identical, with identical voltage ratings (100 V), current ratings (8 A), forward voltage characteristics (900 mV @ 8 A), and package specifications (5-DFN). The primary difference is packaging format (Cut Tape versus Tape & Reel) and product status (Obsolete versus Active). Electrical performance and PCB compatibility are identical.

Q: When should NRVB8H100MFSWFT3G be selected over MBR8H100MFST1G?

A: NRVB8H100MFSWFT3G should be selected when automotive-grade qualification to AEC-Q101 is required. This part carries identical electrical and mechanical specifications but includes automotive qualification. If automotive qualification is not required, either part is suitable based on availability and packaging preference.

Q: Are there package compatibility differences between these parts?

A: All three parts use the identical 5-DFN (5x6) (8-SOFL) package with 8-PowerTDFN, 5 Leads configuration. PCB footprints and assembly processes are identical. Packaging format differences (Tape & Reel versus Cut Tape) affect procurement and handling only, not component placement or electrical function.

Q: What is the significance of the Obsolete status for NRVB8H100MFST1G?

A: Obsolete status indicates the part is no longer in active production. While the part may remain available from existing inventory, future availability is not guaranteed. For new designs or long-term production requirements, Active status parts (MBR8H100MFST1G or NRVB8H100MFSWFT3G) are preferred.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts carry ROHS3 Compliant status and are suitable for applications requiring RoHS compliance. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Q: What is the operating temperature range for these parts?

A: All three parts operate across the identical junction temperature range of -55°C to 175°C, suitable for industrial and automotive temperature environments.
