MBRF20100CTP Equivalent & Substitute Parts

Part Overview

The MBRF20100CTP is a Schottky diode array manufactured by Littelfuse Inc., configured as a 1 Pair Common Cathode arrangement with a maximum reverse voltage rating of 100 V and average rectified current of 10 A per diode. The device is packaged in a TO-220-3 Full Pack with isolated tab for through-hole mounting applications. This part is Active in product status and RoHS3 compliant.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowed specifications for this diode category, enabling direct functional replacement in circuit designs.

Substitute Part Grouping Explanation

Substitution of the MBRF20100CTP is determined by strict equivalence in the following critical parameters:

Diode Configuration: Must be 1 Pair Common Cathode
Technology: Must be Schottky
Voltage - DC Reverse (Vr) (Max): Must be 100 V
Mounting Type: Must be Through Hole
Package / Case: Must be TO-220-3 with Isolated Tab
Operating Temperature Range: Must support -55°C to 150°C junction temperature

The substitute part MBRL20100FCT-BP from Micro Commercial Co meets all these core requirements. While the substitute exhibits higher current rating (20 A vs. 10 A) and improved forward voltage characteristics (720 mV @ 10 A vs. 900 mV @ 10 A), these represent enhanced performance within the same functional category and do not preclude substitution. The reverse leakage current difference (100 µA vs. 1 mA @ 100 V) reflects manufacturing process variation within acceptable Schottky diode specifications.

Engineering Selection Recommendations

The MBRL20100FCT-BP from Micro Commercial Co is a direct functional substitute for the MBRF20100CTP. Both parts maintain Active product status and ROHS3 compliance. The substitute part satisfies all mandatory electrical and mechanical parameters required for TO-220-3 Schottky diode array applications at 100 V reverse voltage.

Selection between the original and substitute part should be based on:

Availability: MBRL20100FCT-BP has higher inventory (6002 Pcs vs. 1483 Pcs)
Performance margin: The substitute provides higher current rating (20 A vs. 10 A) and lower forward voltage drop (720 mV vs. 900 mV @ 10 A)
Regulatory compliance: Both parts meet ROHS3, REACH Unaffected, and EAR99 classifications

No additional testing or verification is required for substitution in applications designed for the MBRF20100CTP.

Frequently Asked Questions (FAQ)

Q: Can MBRL20100FCT-BP replace MBRF20100CTP in existing circuit designs?

A: Yes. Both parts are Schottky diode arrays with 1 Pair Common Cathode configuration, 100 V reverse voltage rating, and TO-220-3 isolated tab packaging. Electrical and mechanical parameters are compatible for direct substitution.

Q: What is the difference in current rating between these parts?

A: The MBRF20100CTP is rated for 10 A average rectified current per diode, while the MBRL20100FCT-BP is rated for 20 A. The substitute provides higher current capacity within the same package and voltage class.

Q: Are the forward voltage characteristics different?

A: Yes. At 10 A forward current, the MBRF20100CTP exhibits 900 mV maximum forward voltage, while the MBRL20100FCT-BP exhibits 720 mV. The substitute demonstrates lower forward voltage drop, resulting in reduced power dissipation.

Q: Do both parts have the same reverse leakage current?

A: No. The MBRF20100CTP has 1 mA reverse leakage at 100 V, while the MBRL20100FCT-BP has 100 µA at 100 V. The substitute exhibits lower leakage current, typical of manufacturing process variations in Schottky diode technology.

Q: Are the packages physically identical?

A: Both parts use TO-220-3 packaging with isolated tab for through-hole mounting. The physical footprint and pin configuration are equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MBRF20100CTP and MBRL20100FCT-BP are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
