Substitute Part Grouping Explanation

Substitution of the MBR1680FCT-BP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Diode Configuration: 1 Pair Common Cathode
Technology: Schottky
Current - Average Rectified (Io): 16 A per diode
Mounting Type: Through Hole
Package / Case: TO-220-3 Isolated Tab
Supplier Device Package: ITO-220AB

Allowable Variation:

Voltage - DC Reverse (Vr) (Max): Equal to or greater than 80 V
Voltage - Forward (Vf) (Max) @ If: Equal to or less than 850 mV @ 8 A
Current - Reverse Leakage @ Vr: Equal to or less than 500 µA at the rated reverse voltage
Operating Temperature - Junction: Equal to or greater than the specified range

The MBR16100FCT-BP qualifies as a substitute because it maintains identical configuration, technology, current rating, and package specifications while providing an elevated reverse voltage rating of 100 V, which is compatible with applications designed for the 80 V rated device.

Engineering Selection Recommendations

The MBR16100FCT-BP is the manufacturer-recommended substitute for the obsolete MBR1680FCT-BP. Selection of this substitute is supported by the following factors:

Product Status: The MBR16100FCT-BP maintains Active product status, ensuring continued availability and manufacturing support from Micro Commercial Co, whereas the MBR1680FCT-BP is classified as Obsolete.

Compliance and Certifications: Both parts share identical REACH Status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.10.0080), confirming regulatory equivalence.

Electrical Compatibility: The substitute part maintains all critical electrical parameters at identical or superior levels. The increased reverse voltage rating of 100 V provides enhanced overvoltage margin while preserving forward voltage characteristics and leakage specifications.

Physical Compatibility: Identical through-hole mounting configuration, TO-220-3 Isolated Tab package, and ITO-220AB supplier device package ensure direct mechanical and thermal interface compatibility without circuit board modification.

Frequently Asked Questions (FAQ)

Q: Can the MBR16100FCT-BP be used as a direct replacement for the MBR1680FCT-BP in existing designs?

A: Yes. The MBR16100FCT-BP is electrically and mechanically compatible with the MBR1680FCT-BP. Both devices share identical diode configuration, current rating, forward voltage characteristics, and package specifications. The elevated reverse voltage rating of the substitute part (100 V versus 80 V) provides additional design margin without introducing incompatibility.

Q: What is the significance of the increased reverse voltage rating in the substitute part?

A: The MBR16100FCT-BP is rated for 100 V maximum reverse voltage compared to 80 V for the MBR1680FCT-BP. This higher rating allows the substitute to operate safely in applications with greater transient overvoltage exposure. Applications designed for 80 V operation remain fully compatible with the 100 V rated device.

Q: Are the thermal and temperature characteristics identical between these parts?

A: Yes. Both the MBR1680FCT-BP and MBR16100FCT-BP operate across the same junction temperature range of -50°C to 125°C, ensuring thermal compatibility in all specified operating environments.

Q: Does the package configuration differ between the main part and substitute?

A: No. Both parts utilize the TO-220-3 Isolated Tab through-hole package with ITO-220AB supplier device package designation. No circuit board layout modifications or thermal management changes are required for substitution.

Q: What is the availability status of each part?

A: The MBR1680FCT-BP is classified as Obsolete, indicating discontinued production. The MBR16100FCT-BP maintains Active product status with ongoing manufacturing support from Micro Commercial Co.
