Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBRF30100CTP is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode configuration must be 1 Pair Common Cathode
• Technology must be Schottky
• Maximum reverse voltage (Vr) must be ≥ 100 V
• Average rectified current (Io) per diode must be ≥ 15 A
• Fast recovery speed characteristic ≤ 500ns, > 200mA (Io)
• Operating temperature range must encompass -55°C to 150°C

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Package must be TO-220-3 configuration with isolated tab
• Supplier device package must be ITO-220AB

Compliance Requirements:

• RoHS3 compliance required
• REACH Unaffected status required

The substitute part MBRL20100FCT-BP meets all electrical and mechanical compatibility criteria, with the exception of higher average rectified current (20 A vs. 15 A), which represents an uprated capability suitable for the same circuit application.

Parameter Comparison

Engineering Selection Recommendations

The MBRL20100FCT-BP from Micro Commercial Co qualifies as a direct substitute for the MBRF30100CTP based on matching electrical configuration, voltage rating, speed characteristics, and thermal operating range. Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for equivalent applications.

The substitute part provides higher average rectified current capacity (20 A vs. 15 A per diode) and lower reverse leakage current (100 µA vs. 1 mA at 100 V), representing improved performance characteristics within the same package footprint and pinout. The forward voltage characteristic differs due to measurement at different current levels; however, both parts maintain fast recovery Schottky performance.

Selection between these parts depends on inventory availability, lead time requirements, and supplier preference, as both meet the specified electrical and mechanical compatibility criteria for TO-220-3 through-hole Schottky diode array applications rated at 100 V.

Frequently Asked Questions (FAQ)

Q: Can MBRL20100FCT-BP replace MBRF30100CTP in existing circuit designs?

A: Yes. Both parts share identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, fast recovery speed, and TO-220-3 isolated tab package. The substitute part's higher current rating (20 A vs. 15 A) and lower reverse leakage do not create compatibility issues in circuits designed for the original part.

Q: Are the pin assignments identical between these parts?

A: Yes. Both parts use the TO-220-3 ITO-220AB package with isolated tab, ensuring identical pinout and mechanical fit for through-hole PCB mounting.

Q: What is the difference in forward voltage between these parts?

A: The MBRF30100CTP specifies 850 mV maximum at 15 A, while the MBRL20100FCT-BP specifies 720 mV maximum at 10 A. Forward voltage varies with current; direct comparison at identical current levels is not provided in the specifications. Both parts meet fast recovery Schottky performance requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MBRF30100CTP and MBRL20100FCT-BP are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for electronic component applications.

Q: What is the significance of the lower reverse leakage in the substitute part?

A: The MBRL20100FCT-BP exhibits lower reverse leakage current (100 µA vs. 1 mA at 100 V), indicating reduced parasitic current flow in reverse bias conditions. This characteristic may provide improved efficiency in applications sensitive to leakage current, though both parts operate within acceptable Schottky diode performance parameters.

Q: Are there any thermal considerations when substituting these parts?

A: Both parts share identical operating temperature range (-55°C to 150°C junction temperature). Thermal management depends on circuit design and heat dissipation requirements rather than part selection between these equivalents.
