Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR2030CT is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V minimum
• Current - Average Rectified (Io) (per Diode): 20 A minimum
• Mounting Type: Through Hole
• Package / Case: TO-220-3

Secondary Compliance Criteria:

• RoHS3 Compliance
• Operating Temperature Range: -55°C to 150°C minimum
• Fast Recovery Speed: ≤ 500ns, > 200mA (Io)

Two substitute parts are identified based on these parameters. The MBR2030CT-G from Comchip Technology maintains full electrical and mechanical equivalence with identical ratings. The MBR2030CTLG from onsemi provides functional substitution with modified electrical characteristics and extended temperature range, suitable for applications where the specified parameters are not exceeded.

Engineering Selection Recommendations

MBR2030CT-G (Comchip Technology) - Direct Equivalent

The MBR2030CT-G is the preferred direct substitute for the MBR2030CT. This part maintains identical electrical specifications across all critical parameters: 30 V reverse voltage, 20 A average rectified current, 840 mV forward voltage at 20 A, and identical reverse leakage characteristics. The component is ROHS3 compliant and currently in Active product status, ensuring long-term availability. The TO-220-3 package and through-hole mounting are identical to the original part. This substitute requires no circuit redesign or thermal management modifications.

MBR2030CTLG (onsemi) - Functional Substitute with Derating

The MBR2030CTLG from onsemi provides functional substitution for applications operating below 10 A average rectified current. This part carries Last Time Buy status and is ROHS3 compliant. The 30 V reverse voltage rating and TO-220-3 package are maintained. However, the current rating is reduced to 10 A per diode, and reverse leakage increases to 5 mA at 30 V. The forward voltage at rated current is 520 mV at 10 A. The extended operating temperature range (-65°C to 175°C) provides thermal margin beyond the original specification. Selection of this part requires verification that circuit current demands do not exceed 10 A per diode.

Frequently Asked Questions (FAQ)

Q: Can the MBR2030CT-G be used as a direct replacement without circuit modification?

A: Yes. The MBR2030CT-G maintains identical electrical and mechanical specifications to the MBR2030CT across all critical parameters. No circuit redesign, thermal management changes, or PCB layout modifications are required. The part is pin-compatible and functionally equivalent.

Q: What is the primary limitation of the MBR2030CTLG substitute?

A: The MBR2030CTLG is rated for 10 A average rectified current per diode, compared to 20 A for the original MBR2030CT. Applications requiring sustained current above 10 A per diode cannot use this substitute without exceeding component ratings. Reverse leakage current is also higher at 5 mA versus 100 µA.

Q: Are all substitute parts compliant with ROHS3 and REACH regulations?

A: The MBR2030CT-G is ROHS3 compliant and REACH Unaffected. The MBR2030CTLG is ROHS3 compliant and REACH Unaffected. The original MBR2030CT is ROHS3 compliant and REACH Affected. All parts meet current environmental compliance standards for new designs.

Q: Do the substitute parts use the same TO-220-3 package?

A: Yes. Both MBR2030CT-G and MBR2030CTLG use the TO-220-3 through-hole package. The MBR2030CT-G supplier device package is designated TO-220AB, and the MBR2030CTLG is designated TO-220, but both are mechanically and electrically compatible with TO-220-3 PCB footprints and mounting hardware.

Q: What is the difference in forward voltage between the original and substitute parts?

A: The MBR2030CT and MBR2030CT-G both specify 840 mV maximum forward voltage at 20 A. The MBR2030CTLG specifies 520 mV maximum forward voltage at 10 A. Forward voltage characteristics are current-dependent; direct comparison at different current levels is not applicable for substitution decisions.

Q: Which substitute part has the longest product lifecycle?

A: The MBR2030CT-G from Comchip Technology is in Active product status, indicating ongoing production and availability. The MBR2030CTLG from onsemi is in Last Time Buy status, indicating limited future availability. For new designs requiring long-term component supply, the MBR2030CT-G is the preferred selection.
