Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB1640CT-TP is determined by the following critical parameters:

Configuration Match: The substitute part must maintain the same diode configuration (1 pair common cathode) and Schottky technology to ensure functional equivalence in the circuit topology.

Electrical Ratings: The substitute part must support the same average rectified current per diode (16 A). The reverse voltage rating of the substitute may equal or exceed the original part rating (40 V minimum), as a higher voltage rating provides backward compatibility without functional degradation.

Thermal and Speed Characteristics: The substitute must maintain the same operating temperature range (-55°C to 125°C junction temperature) and fast recovery speed specification (≤ 500ns, > 200mA).

Package Compatibility: The substitute must use the identical surface mount package (TO-263-3, D2PAK with 2 leads plus tab) to ensure mechanical and electrical compatibility with existing printed circuit board layouts.

Parameter Comparison

Engineering Selection Recommendations

The MBRB1645CT-TP is the manufacturer-recommended substitute for the obsolete MBRB1640CT-TP. Both parts are manufactured by Micro Commercial Co and share identical REACH and ECCN compliance status (REACH Unaffected, EAR99).

The MBRB1645CT-TP maintains all critical electrical and thermal specifications of the original part while providing a higher reverse voltage rating (45 V versus 40 V). This increased voltage margin does not introduce any functional incompatibility and provides additional design margin in applications operating near the original voltage specification.

The MBRB1645CT-TP is currently in active production status, ensuring long-term availability and supply chain continuity. The identical D2PAK package and pinout configuration enable direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the MBRB1645CT-TP be used as a direct replacement for the MBRB1640CT-TP?

A: Yes. The MBRB1645CT-TP is electrically and mechanically compatible with the MBRB1640CT-TP. Both parts share identical diode configuration, current rating, forward voltage characteristics, speed specifications, operating temperature range, and D2PAK package. The higher reverse voltage rating (45 V) of the substitute part provides backward compatibility.

Q: What is the difference between the MBRB1640CT-TP and MBRB1645CT-TP?

A: The primary difference is the maximum reverse voltage rating: MBRB1640CT-TP is rated for 40 V, while MBRB1645CT-TP is rated for 45 V. All other electrical parameters, including current capacity, forward voltage, leakage current, and thermal characteristics, are identical. The MBRB1645CT-TP is also in active production status, whereas the MBRB1640CT-TP is obsolete.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical TO-263-3 D2PAK surface mount package with 2 leads plus tab. Pinout and mechanical dimensions are identical, enabling direct substitution on existing printed circuit boards.

Q: Does the higher voltage rating of the MBRB1645CT-TP affect circuit performance?

A: No. A higher reverse voltage rating does not degrade performance in applications designed for the original 40 V specification. The substitute part operates within the same electrical parameters and provides additional voltage margin.

Q: What compliance certifications apply to both parts?

A: Both the MBRB1640CT-TP and MBRB1645CT-TP carry identical REACH and ECCN classifications: REACH Unaffected and EAR99. Both parts are classified under HTSUS code 8541.10.0080.
