MBRB1630CT-TP Equivalent & Substitute Parts

Part Overview

The MBRB1630CT-TP is a Schottky diode array manufactured by Micro Commercial Co, configured as 1 pair common cathode with a maximum reverse voltage rating of 30 V and average rectified current of 16 A per diode. The device is packaged in a Surface Mount TO-263-3 D2PAK format with 2 leads plus tab configuration.

This part is classified as Obsolete. Identification of equivalent and substitute components is necessary to support ongoing design requirements, manufacturing continuity, and system maintenance where the original part is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB1630CT-TP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (electrical topology must match)
• Technology: Schottky (device type must remain consistent)
• Mounting Type: Surface Mount (assembly process compatibility)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (physical and thermal interface)
• Current - Average Rectified (Io): 16 A per diode (current handling capacity)

Allowable Parameter Variance:

• Voltage - DC Reverse (Vr) (Max): Substitute parts may have equal or higher voltage ratings. A higher voltage rating provides design margin and does not compromise circuit function in applications rated for 30 V operation.
• Voltage - Forward (Vf) (Max) @ If: Identical specification across substitute parts
• Speed: Identical specification across substitute parts
• Current - Reverse Leakage @ Vr: Specification at substitute part's rated voltage
• Operating Temperature - Junction: Identical specification across substitute parts

The MBRB1645CT-TP qualifies as a direct substitute based on these criteria. It maintains identical configuration, technology, mounting, package, and current rating while providing an elevated voltage rating of 45 V, which is compatible with 30 V circuit applications.

Engineering Selection Recommendations

The MBRB1645CT-TP is the manufacturer-recommended substitute for the obsolete MBRB1630CT-TP. Selection of this substitute is based on the following engineering factors:

Product Status Consideration: The MBRB1630CT-TP is classified as Obsolete, whereas the MBRB1645CT-TP is Active production status. Active production status ensures ongoing availability, supply chain stability, and manufacturer support for new designs and manufacturing operations.

Electrical Compatibility: The MBRB1645CT-TP maintains all critical electrical parameters identical to the main part: 16 A average rectified current per diode, 700 mV forward voltage at 8 A, and fast recovery switching characteristics. The elevated reverse voltage rating of 45 V (compared to 30 V) provides additional design margin without introducing functional incompatibility in circuits specified for 30 V operation.

Physical and Thermal Interface: Both parts utilize identical Surface Mount packaging in TO-263-3 D2PAK format with 2 leads plus tab. PCB layout, thermal management, and assembly processes require no modification.

Regulatory Compliance: Both parts maintain identical REACH Unaffected status and ECCN classification (EAR99), ensuring no change to regulatory or export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the MBRB1645CT-TP be used as a direct replacement for the MBRB1630CT-TP in existing designs?

A: Yes. The MBRB1645CT-TP is electrically and mechanically compatible with the MBRB1630CT-TP. Both devices share identical diode configuration, current rating, forward voltage characteristics, switching speed, and package format. No circuit modifications or PCB redesign are required.

Q: Why does the substitute part have a higher voltage rating (45 V vs. 30 V)?

A: The MBRB1645CT-TP is rated for 45 V maximum reverse voltage, while the MBRB1630CT-TP is rated for 30 V. In applications designed for 30 V operation, the higher voltage rating of the substitute part provides additional design margin and does not compromise circuit performance. The device will operate within its specified parameters at voltages up to 30 V.

Q: Are there any differences in forward voltage drop between these parts?

A: No. Both the MBRB1630CT-TP and MBRB1645CT-TP specify identical forward voltage characteristics of 700 mV maximum at 8 A forward current. Power dissipation and thermal behavior remain equivalent.

Q: Do these parts have the same switching speed?

A: Yes. Both parts are specified as Fast Recovery devices with switching time ≤ 500 ns at forward currents > 200 mA. Switching performance is identical.

Q: Is the D2PAK package identical between both parts?

A: Yes. Both parts use the Surface Mount TO-263-3 D2PAK package with 2 leads plus tab (TO-263AB). Pin configuration, lead spacing, and thermal tab dimensions are identical. No PCB layout changes are necessary.

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

A: The MBRB1630CT-TP specifies 100 µA reverse leakage at 30 V, while the MBRB1645CT-TP specifies 100 µA reverse leakage at 45 V. Each specification is measured at the respective part's rated voltage. At 30 V operation, the leakage characteristics of the substitute part will be equivalent to or better than the original part.

Q: Is the MBRB1645CT-TP available in the same packaging format?

A: Yes. The MBRB1645CT-TP is supplied in bulk packaging, identical to the original part's Surface Mount D2PAK format. No packaging or handling changes are required for assembly operations.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification. No changes to regulatory documentation, export compliance, or material declarations are required when substituting the MBRB1645CT-TP for the MBRB1630CT-TP.
