MBRF20100CTL Equivalent & Substitute Parts

Part Overview

The MBRF20100CTL is a Schottky diode array manufactured by Diodes Incorporated, configured as a 1 Pair Common Cathode device rated for 100 V DC reverse voltage and 20 A average rectified current per diode. The component is packaged in an ITO-220AB (isolated tab) through-hole format. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRF20100CTL is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Diode configuration must be 1 Pair Common Cathode
• Technology must be Schottky
• Voltage - DC Reverse (Vr) (Max) must be 100 V
• Current - Average Rectified (Io) (per Diode) must be rated for 20 A or higher

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Package case must be TO-220-3 Full Pack with Isolated Tab
• Supplier device package must be ITO-220AB

Compliance Requirements:

• RoHS3 Compliant status required
• Moisture Sensitivity Level (MSL) 1 (Unlimited) required

Substitute parts are grouped by current rating. The MBRF20100CTL operates at 20 A; therefore, direct substitutes must support 20 A or higher current ratings while maintaining all other electrical and mechanical parameters. Parts with lower current ratings (5 A, 10 A, 15 A) are listed for reference but do not constitute direct electrical equivalents for 20 A applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (20 A Rating):

The DSTF40100C (Littelfuse Inc.) is the primary direct substitute for the MBRF20100CTL. Both components share identical electrical specifications: 100 V DC reverse voltage, 20 A average rectified current per diode, 1 Pair Common Cathode configuration, and ITO-220AB package format. The DSTF40100C is currently in active production status with ROHS3 compliance and MSL 1 rating. This part provides direct pin-for-pin and functional compatibility.

The DSTF60100C (Littelfuse Inc.) is a higher-current alternative rated for 30 A per diode. This component maintains all mechanical and electrical compatibility parameters while providing increased current capacity. The DSTF60100C is active production status with identical compliance certifications.

Current-Limited Alternatives:

The DSTF20100C and DSTF30100C (Littelfuse Inc.) and DSA20C100PN and DSA30C100PN (IXYS) are lower-current alternatives rated for 10 A and 15 A respectively. These parts maintain the 100 V voltage rating and common cathode configuration but are not electrically equivalent for 20 A applications. Selection of these parts requires circuit redesign or current derating.

Compliance and Availability:

All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original component specifications. All active-status substitutes are currently in production with documented inventory availability.

Frequently Asked Questions (FAQ)

Q: Can DSTF40100C directly replace MBRF20100CTL in existing designs?

A: Yes. The DSTF40100C provides direct electrical and mechanical compatibility. Both components are rated for 100 V, 20 A per diode, configured as 1 Pair Common Cathode, and packaged in ITO-220AB format. No circuit modifications are required.

Q: What is the difference between ITO-220AB and TO-220ABFP packages?

A: ITO-220AB denotes an isolated tab TO-220-3 package, while TO-220ABFP denotes a full pack TO-220-3 package without isolated tab. These are mechanically different. The MBRF20100CTL uses ITO-220AB (isolated tab). Parts specified with TO-220ABFP (DSA20C100PN, DSA30C100PN) have different thermal and electrical isolation characteristics and require verification of PCB layout compatibility.

Q: Can I use DSTF60100C (30 A) instead of DSTF40100C (20 A)?

A: Yes. The DSTF60100C is rated for higher current capacity and maintains all other electrical parameters. This substitution provides additional design margin and is electrically compatible. No circuit modifications are required.

Q: Why are lower-current parts (DSTF20100C, DSTF30100C, DSA20C100PN, DSA30C100PN) listed if they cannot directly replace MBRF20100CTL?

A: These parts are listed as reference alternatives for applications where current requirements can be reduced or where circuit redesign is acceptable. They share the same voltage rating, diode configuration, and technology but operate at reduced current capacity. Direct substitution in 20 A circuits is not supported.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original MBRF20100CTL specifications.

Q: What is the primary reason to substitute MBRF20100CTL?

A: The MBRF20100CTL is classified as obsolete. The DSTF40100C and DSTF60100C are active production alternatives from Littelfuse Inc. that provide equivalent or superior electrical performance with current availability and long-term supply assurance.
