Substitute Part Grouping Explanation

Substitute components for the MBRF2090HC0G are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 90 V
• Current - Average Rectified (Io): 20 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 20 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 100 µA @ 90 V

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: TO-220-2 Full Pack
• Supplier Device Package: ITO-220AC

Compliance & Qualification (Must Match):

• Technology: Schottky
• Grade: Automotive
• Qualification: AEC-Q101
• Operating Temperature - Junction: -55°C ~ 150°C
• RoHS Status: ROHS3 Compliant

All substitute parts listed maintain identical specifications across these parameters, ensuring direct functional and mechanical compatibility without circuit redesign or thermal management modifications.

Parameter Comparison

Engineering Selection Recommendations

MBRF2090H is the primary direct substitute for the discontinued MBRF2090HC0G. This component is currently in active production status and maintains complete electrical and mechanical equivalence. The MBRF2090H carries identical automotive-grade qualification (AEC-Q101) and ROHS3 compliance, enabling direct board-level replacement without design modification.

MBRF2090C0G is a parametric equivalent that provides identical electrical performance and mechanical compatibility. This component is also in active production status and meets all automotive and environmental compliance requirements. Selection between MBRF2090H and MBRF2090C0G is based on supplier availability and procurement lead times, as both components are functionally interchangeable.

Both substitute parts are suitable for applications requiring 90V reverse voltage rating, 20A average rectified current, and fast recovery Schottky diode characteristics in automotive-grade implementations. Component selection should be based on current inventory availability and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can MBRF2090H be used as a direct replacement for MBRF2090HC0G?

A: Yes. The MBRF2090H is a direct substitute with identical electrical specifications (90V, 20A, 950mV forward voltage), matching speed characteristics (fast recovery ≤ 500ns), identical package configuration (TO-220-2 ITO-220AC), and equivalent automotive-grade qualification (AEC-Q101). No circuit modifications are required.

Q: What is the difference between MBRF2090H and MBRF2090C0G?

A: Both components are parametric equivalents with identical electrical and mechanical specifications. The difference lies in manufacturing part number designation only. Both are active production components from Taiwan Semiconductor Corporation with equivalent performance characteristics and compliance certifications.

Q: Are the substitute parts compatible with the original PCB layout?

A: Yes. Both MBRF2090H and MBRF2090C0G use the identical TO-220-2 Full Pack configuration with ITO-220AC supplier device package, ensuring mechanical and thermal compatibility with existing through-hole mounting patterns and thermal management designs.

Q: Do the substitute parts maintain automotive qualification?

A: Yes. Both MBRF2090H and MBRF2090C0G are automotive-grade components qualified to AEC-Q101 standards, matching the qualification level of the original MBRF2090HC0G. Operating temperature range (-55°C ~ 150°C) is identical across all three components.

Q: Are there any compliance or environmental differences?

A: No. All three components (MBRF2090HC0G, MBRF2090H, and MBRF2090C0G) are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Environmental and regulatory compliance is equivalent across all parts.

Q: What is the current availability status of substitute parts?

A: MBRF2090H is in active production with 1022 pieces in stock. MBRF2090C0G is in active production with 989 pieces in stock. The original MBRF2090HC0G is discontinued at DiGi Electronics, making the active substitutes the recommended selection for new procurement.
