MBRM3100-13-F Equivalent & Substitute Parts

Part Overview

The MBRM3100-13-F is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 100 V DC reverse voltage and 3 A average rectified current in a Powermite®3 surface mount package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. Equivalent alternatives maintain the same electrical performance characteristics while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBRM3100-13-F are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 760 mV @ 3 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Acceptable Variations:

• Package / Case: Different surface mount packages (Powermite®3, PowerDI™5) are acceptable provided electrical performance is maintained
• Current - Reverse Leakage @ Vr: Minor variations within engineering tolerance
• Operating Temperature - Junction: Extended ranges are acceptable
• Product Status: Active products are preferred over obsolete classifications
• Manufacturer: Alternative qualified manufacturers are acceptable

Engineering Selection Recommendations

PDS3100-13 (Diodes Incorporated)

The PDS3100-13 is a direct manufacturer equivalent from Diodes Incorporated with active product status. This part maintains all critical electrical parameters identical to the MBRM3100-13-F, including reverse voltage, rectified current, forward voltage, and switching speed. The primary difference is the package format (PowerDI™5 versus Powermite®3), which requires PCB layout modification. The extended operating temperature range (-65°C ~ 150°C) provides additional thermal margin. ROHS3 compliance and unlimited MSL rating are maintained. This substitute is suitable for applications where PCB redesign for the PowerDI™5 package is feasible.

UPS3100E3/TR13 (Microchip Technology)

The UPS3100E3/TR13 is a parametric equivalent from Microchip Technology with active product status. This part maintains the same Powermite®3 package as the original MBRM3100-13-F, eliminating the need for PCB layout changes. All critical electrical parameters match the main part specification, with the exception of reverse leakage current (200 µA versus 100 µA at 100 V), which remains within acceptable engineering tolerance for most applications. ROHS3 compliance and unlimited MSL rating are maintained. This substitute is suitable for direct board-level replacement without layout modification.

Frequently Asked Questions (FAQ)

Q: Can PDS3100-13 be used as a direct replacement for MBRM3100-13-F without PCB modification?

A: No. The PDS3100-13 uses the PowerDI™5 package, while the MBRM3100-13-F uses Powermite®3. These packages have different footprints and pin configurations, requiring PCB layout redesign.

Q: Can UPS3100E3/TR13 be used as a direct replacement for MBRM3100-13-F without PCB modification?

A: Yes. The UPS3100E3/TR13 uses the same Powermite®3 package as the MBRM3100-13-F and maintains identical electrical specifications, allowing direct board-level substitution.

Q: What is the significance of the reverse leakage current difference between MBRM3100-13-F (100 µA) and UPS3100E3/TR13 (200 µA)?

A: The reverse leakage current difference of 100 µA at 100 V represents a 2x variation. This difference is within normal manufacturing tolerance for Schottky diodes and does not affect functionality in standard rectification applications. Applications with stringent leakage requirements should evaluate circuit-level impact.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both PDS3100-13 and UPS3100E3/TR13 are ROHS3 compliant, matching the compliance status of the original MBRM3100-13-F.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging provides individual component strips suitable for manual assembly or small-volume applications. Tape & Reel packaging provides continuous reels suitable for automated assembly equipment. Both formats contain identical components; the difference is in delivery and handling format.

Q: Does the extended operating temperature range of PDS3100-13 (-65°C ~ 150°C) provide any functional advantage?

A: The extended temperature range provides additional thermal margin for applications operating at temperature extremes. However, the original MBRM3100-13-F specification (-55°C ~ 125°C) is sufficient for most industrial and commercial applications. The extended range is a design benefit but not a functional requirement for standard applications.

Q: Are there any compliance or certification differences between the substitute parts?

A: Both substitute parts maintain ROHS3 compliance and unlimited MSL rating. PDS3100-13 is REACH Unaffected, while UPS3100E3/TR13 is also REACH Unaffected. Both carry EAR99 ECCN classification. No material compliance differences exist that would restrict substitution.
