MBRB1035-TP Equivalent & Substitute Parts

Part Overview

The MBRB1035-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 35 V DC reverse voltage and 10 A average rectified current in a surface mount D2PAK package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The MBRB1035-TP remains available in inventory (854 pieces), but its obsolete status requires engineers to evaluate suitable alternatives for long-term component sourcing and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB1035-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Technology: Schottky rectifier diode
• Current Rating: 10 A average rectified current (Io)
• Voltage Rating: Minimum 35 V DC reverse voltage (Vr)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature Range: -65°C to 150°C junction temperature

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB
• Supplier Device Package: D2PAK

The MBRB1040-TP qualifies as a direct substitute because it maintains identical current rating (10 A), matching package configuration (D2PAK), equivalent speed classification (Fast Recovery ≤ 500ns, > 200mA), and identical operating temperature range (-65°C to 150°C). The MBRB1040-TP provides a higher voltage rating (40 V versus 35 V), which is acceptable for applications designed for the MBRB1035-TP, as the substitute operates within the same thermal and mechanical envelope while offering enhanced voltage margin.

Parameter Comparison

Engineering Selection Recommendations

The MBRB1040-TP is the designated substitute for the obsolete MBRB1035-TP based on the following engineering factors:

Product Status Alignment: The MBRB1040-TP carries Active product status, ensuring continued availability and manufacturing support, whereas the MBRB1035-TP is classified as Obsolete. This transition is necessary for designs requiring long-term component sourcing and supply chain continuity.

Compliance and Certifications: The MBRB1040-TP is RoHS3 Compliant and carries Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating superior environmental compliance and handling characteristics compared to the MBRB1035-TP. Both parts maintain REACH Unaffected status and EAR99 export classification.

Electrical Performance: The MBRB1040-TP provides a 5 V higher reverse voltage rating (40 V versus 35 V) while maintaining identical 10 A current capacity and fast recovery speed characteristics. The substitute exhibits lower reverse leakage current (100 µA @ 40 V versus 500 µA @ 35 V), indicating improved device quality and reduced power dissipation in reverse bias conditions.

Mechanical and Thermal Compatibility: Both parts utilize identical D2PAK surface mount packaging and share the same operating temperature range (-65°C to 150°C junction temperature), ensuring direct mechanical and thermal interchangeability in existing PCB layouts and thermal management designs.

Frequently Asked Questions (FAQ)

Q: Can the MBRB1040-TP directly replace the MBRB1035-TP in existing designs?

A: Yes. The MBRB1040-TP is a direct substitute. Both parts share identical current rating (10 A), package configuration (D2PAK), speed classification (Fast Recovery ≤ 500ns), and operating temperature range (-65°C to 150°C). The higher voltage rating (40 V versus 35 V) of the substitute provides additional voltage margin without affecting circuit operation in applications designed for 35 V operation.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Product Status—MBRB1040-TP is Active while MBRB1035-TP is Obsolete; (2) Voltage Rating—40 V versus 35 V; (3) Reverse Leakage—100 µA @ 40 V versus 500 µA @ 35 V; (4) Compliance—MBRB1040-TP is RoHS3 Compliant with MSL 1 rating. Forward voltage characteristics differ due to different measurement conditions (600 mV @ 10 A versus 840 mV @ 20 A).

Q: Are the packages identical?

A: Yes. Both parts use the TO-263-3 D2PAK (2 Leads + Tab) surface mount package, designated as TO-263AB. No PCB layout modifications are required for substitution.

Q: What is the inventory status of the substitute part?

A: The MBRB1040-TP has 734 pieces of new original stock available, compared to 854 pieces for the obsolete MBRB1035-TP.

Q: Does the MBRB1040-TP meet current environmental standards?

A: Yes. The MBRB1040-TP is RoHS3 Compliant and carries Moisture Sensitivity Level 1 (Unlimited), indicating compliance with current environmental regulations and superior handling characteristics. Both parts maintain REACH Unaffected status.

Q: Can I use the MBRB1040-TP in applications requiring exactly 35 V operation?

A: Yes. The MBRB1040-TP is rated for 40 V maximum reverse voltage, which exceeds the 35 V requirement. The substitute operates safely in circuits designed for 35 V operation, with the additional voltage rating providing design margin.
