Substitute Part Grouping Explanation

Substitution of the MURD620CTG is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (mandatory match)
• Voltage - DC Reverse (Vr) (Max): 200 V (mandatory match)
• Current - Average Rectified (Io) (per Diode): 3 A minimum (equal or higher acceptable)
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63 (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Operating Temperature - Junction: -65°C to 175°C (mandatory match)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max) @ If: Variations acceptable within circuit design margins
• Reverse Recovery Time (trr): Variations acceptable for non-critical timing applications
• Current - Reverse Leakage @ Vr: Variations acceptable within circuit design margins
• Technology: Standard or enhanced technologies acceptable
• RoHS and REACH Compliance: ROHS3 Compliant and REACH Unaffected (mandatory match)

Substitute parts are grouped into three categories: MFR Recommended (direct replacement from same manufacturer), Similar (equivalent electrical performance with different technology or current rating), and Parametric Equivalent (identical electrical specifications with different packaging or qualification).

Engineering Selection Recommendations

MURD620CTT4G (onsemi) - MFR Recommended Substitute

MURD620CTT4G is the primary recommended substitute for the obsolete MURD620CTG. Both parts are manufactured by onsemi and share identical electrical specifications: 200 V reverse voltage, 3 A average rectified current per diode, 1 V forward voltage at 3 A, 35 ns reverse recovery time, and 5 µA reverse leakage current at 200 V. The critical distinction is product status: MURD620CTT4G is active with 79,595 units in stock, whereas MURD620CTG is obsolete. Both comply with ROHS3 and REACH regulations. The packaging, mounting type, and temperature range are identical. This part is suitable for direct replacement in existing designs without circuit modification.

VS-MURD620CTHM3 (Vishay) - Parametric Equivalent

VS-MURD620CTHM3 is a parametric equivalent offering identical electrical performance to the MURD620CTG: 200 V reverse voltage, 3 A average rectified current per diode, 1 V forward voltage at 3 A, 35 ns reverse recovery time, and 5 µA reverse leakage current at 200 V. This Vishay part carries automotive grade qualification and AEC-Q101 certification, providing enhanced reliability assurance for automotive applications. The part is active with 30,100 units in stock. Packaging and mounting specifications are identical. This substitute is appropriate for applications requiring automotive-grade components.

RURD620CCS9A-F085 (onsemi) - Similar Substitute with Enhanced Current Rating

RURD620CCS9A-F085 provides equivalent voltage specifications (200 V reverse voltage) and package compatibility but with doubled current capacity (6 A versus 3 A per diode). This avalanche technology diode array features 30 ns reverse recovery time and 100 µA reverse leakage current at 200 V. The part carries automotive grade qualification and AEC-Q101 certification. This substitute is suitable for applications where higher current capacity provides design margin or where future current requirements may increase. The part is active with 10,000 units in stock.

VS-MURD620CT-M3 (Vishay) - Similar Substitute with Enhanced Current Rating

VS-MURD620CT-M3 provides equivalent voltage specifications (200 V reverse voltage) and package compatibility but with doubled current capacity (6 A versus 3 A per diode). This FRED Pt® series standard technology diode features 19 ns reverse recovery time and 5 µA reverse leakage current at 200 V. The part is active with 5,400 units in stock. This substitute is suitable for applications where higher current capacity provides design margin or where superior reverse recovery time performance is beneficial.

SBR6200CTL-13 (Diodes Incorporated) - Similar Substitute with Different Technology

SBR6200CTL-13 provides equivalent voltage specifications (200 V reverse voltage), current rating (3 A per diode), and package compatibility. This Super Barrier technology diode array features 850 mV forward voltage at 3 A and standard recovery speed classification (>500ns). The part is active with 10,300 units in stock and complies with ROHS3 and REACH regulations. This substitute is suitable for applications where forward voltage reduction is beneficial for thermal management, though the standard recovery speed classification differs from the fast recovery classification of the MURD620CTG.

Frequently Asked Questions (FAQ)

Q: Can MURD620CTT4G be used as a direct replacement for MURD620CTG?

A: Yes. MURD620CTT4G is the manufacturer-recommended substitute with identical electrical specifications, package, and mounting type. The only difference is product status: MURD620CTT4G is active while MURD620CTG is obsolete. No circuit modifications are required.

Q: What is the difference between the onsemi and Vishay substitutes?

A: MURD620CTT4G (onsemi) and VS-MURD620CTHM3 (Vishay) both provide identical electrical performance to the MURD620CTG. VS-MURD620CTHM3 carries automotive grade qualification and AEC-Q101 certification, making it suitable for automotive applications. Both are active products with adequate inventory.

Q: Why would I choose RURD620CCS9A-F085 or VS-MURD620CT-M3 over the direct equivalents?

A: These parts offer doubled current capacity (6 A versus 3 A per diode) while maintaining 200 V reverse voltage and identical packaging. Selection depends on circuit requirements: if the application requires higher current capacity or design margin, these substitutes provide enhanced performance. RURD620CCS9A-F085 carries automotive qualification; VS-MURD620CT-M3 features faster reverse recovery time (19 ns versus 35 ns).

Q: Is SBR6200CTL-13 compatible with the MURD620CTG?

A: SBR6200CTL-13 is compatible from a package and voltage perspective (200 V, 3 A, TO-252-3 DPAK). However, it uses Super Barrier technology with 850 mV forward voltage and standard recovery speed (>500ns), differing from the MURD620CTG's standard technology with 1 V forward voltage and fast recovery speed (≤500ns). Selection depends on circuit tolerance for these parameter variations.

Q: Do all substitute parts comply with RoHS3 and REACH regulations?

A: Yes. All substitute parts listed (MURD620CTT4G, RURD620CCS9A-F085, SBR6200CTL-13, VS-MURD620CT-M3, and VS-MURD620CTHM3) are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the MURD620CTG.

Q: What is the significance of automotive grade and AEC-Q101 qualification?

A: Automotive grade designation and AEC-Q101 qualification indicate that a component has undergone enhanced reliability testing and qualification procedures required for automotive applications. RURD620CCS9A-F085 and VS-MURD620CTHM3 carry these qualifications, making them suitable for automotive designs where such certification is required.

Q: Are there inventory differences between the substitute parts?

A: Yes. MURD620CTT4G has the highest inventory (79,595 units), followed by VS-MURD620CTHM3 (30,100 units), SBR6200CTL-13 (10,300 units), and RURD620CCS9A-F085 (10,000 units). Inventory levels should be considered for production planning and lead time requirements.

Q: Can I use a higher current-rated substitute in a circuit designed for 3 A?

A: Yes. Using a higher current-rated diode (6 A) in a circuit designed for 3 A operation is acceptable. The diode will operate within its safe operating region with additional current margin. This approach is common in design for reliability and future design flexibility.

Q: What is the difference between fast recovery and standard recovery speed classifications?

A: Fast recovery (≤500ns) diodes have shorter reverse recovery time, reducing switching losses and electromagnetic interference in high-frequency applications. Standard recovery (>500ns) diodes are suitable for lower-frequency applications where reverse recovery time is less critical. The MURD620CTG uses fast recovery; SBR6200CTL-13 uses standard recovery.
