Engineering Selection Recommendations

MBR20100CTF-G1 (Diodes Incorporated)

The MBR20100CTF-G1 is the primary direct equivalent for the obsolete MBR20100CTF-E1. Both parts share identical electrical specifications: 100 V reverse voltage, 10 A average rectified current, and 850 mV forward voltage at 10 A. The MBR20100CTF-G1 carries Active product status and includes AEC-Q101 automotive qualification. This part is suitable for direct replacement in existing designs without circuit modification.

MBRF20100CTG (onsemi)

The MBRF20100CTG is a parametric equivalent manufactured by onsemi under the SWITCHMODE™ series. It maintains identical voltage and current ratings (100 V, 10 A) and forward voltage characteristics (850 mV @ 10 A). The part carries Active product status and ROHS3 compliance. The MBRF20100CTG is suitable for applications requiring onsemi component sourcing or supply chain diversification.

MBRF30H100CTG (onsemi)

The MBRF30H100CTG is a parametric equivalent with enhanced current rating (15 A per diode versus 10 A). It maintains the 100 V reverse voltage specification and operates within the same TO-220-3 Full Pack package. This part is suitable for applications where increased current capacity provides design margin or where thermal performance improvements are beneficial. The MBRF30H100CTG carries Active product status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the MBR20100CTF-G1 be used as a direct replacement for the MBR20100CTF-E1?

A: Yes. The MBR20100CTF-G1 is a direct equivalent with identical electrical specifications (100 V, 10 A, 850 mV forward voltage) and the same TO-220-3 Full Pack package. The primary difference is product status: MBR20100CTF-G1 is Active while MBR20100CTF-E1 is Obsolete. No circuit modifications are required.

Q: What is the difference between the MBR20100CTF-G1 and MBRF20100CTG?

A: Both parts share identical electrical ratings (100 V, 10 A, 850 mV forward voltage) and package specifications (TO-220-3 Full Pack). The primary differences are manufacturer (Diodes Incorporated versus onsemi) and reverse leakage current (50 µA versus 150 µA at 100 V). Both are suitable direct replacements for the MBR20100CTF-E1.

Q: Can the MBRF30H100CTG be used in place of the MBR20100CTF-E1?

A: Yes, with design consideration. The MBRF30H100CTG maintains the 100 V reverse voltage and TO-220-3 Full Pack package but provides 15 A current capacity versus 10 A. This higher rating is compatible with applications designed for 10 A operation and provides additional thermal margin. No circuit modifications are required.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Diode Configuration (1 Pair Common Cathode), (2) Technology (Schottky), (3) Voltage - DC Reverse (100 V), (4) Mounting Type (Through Hole), and (5) Package (TO-220-3 Full Pack). Current rating must equal or exceed 10 A per diode. All substitute parts meet these criteria.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (MBR20100CTF-G1, MBRF30H100CTG, MBRF20100CTG, and STPS20S100CFP) carry ROHS3 Compliant status, matching the compliance requirement of the MBR20100CTF-E1.

Q: What is the difference in packaging between the MBR20100CTF-E1 and the substitute parts?

A: The MBR20100CTF-E1 is supplied in Full Pack packaging. All substitute parts are supplied in Tube packaging. Both packaging formats are compatible with standard component handling and assembly processes. The physical component dimensions and pin configuration remain identical across all parts.

Q: Which substitute part has the lowest reverse leakage current?

A: The STPS20S100CFP (STMicroelectronics) has the lowest reverse leakage current at 3.5 µA @ 100 V, followed by the MBRF30H100CTG at 4.5 µA @ 100 V. The MBR20100CTF-E1 specifies 100 µA @ 100 V. Lower leakage current may provide improved performance in applications sensitive to leakage effects.

Q: Can these parts be used interchangeably in automotive applications?

A: The MBR20100CTF-G1 carries AEC-Q101 automotive qualification. The other substitute parts (MBRF30H100CTG, MBRF20100CTG, STPS20S100CFP) do not list automotive qualification in the provided specifications. For automotive applications, the MBR20100CTF-G1 is the recommended choice.
