Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBRB1635CT-TP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode configuration: 1 pair common cathode
• Technology: Schottky
• Mounting type: Surface mount
• Package: TO-263-3 D2PAK (2 leads + tab)
• Current rating: 16 A per diode minimum
• Operating temperature range: -55°C ~ 125°C minimum

Allowable Parameter Variance:

• Voltage - DC Reverse (Vr): Equal to or greater than 35 V
• Forward voltage (Vf): Equal to or less than 700 mV @ 8 A
• Reverse leakage current: Equal to or less than 100 µA at rated voltage
• Speed: Fast recovery ≤ 500 ns, > 200 mA (Io)

The MBRB1645CT-TP qualifies as a direct substitute because it maintains identical configuration, technology, mounting, and package specifications while providing an elevated reverse voltage rating of 45 V, which is compatible with applications designed for the 35 V rated part.

Engineering Selection Recommendations

The MBRB1645CT-TP is the manufacturer-recommended substitute for the obsolete MBRB1635CT-TP. Selection of this substitute is supported by the following factors:

Product Status: The MBRB1645CT-TP maintains active product status, ensuring continued availability and manufacturing support from Micro Commercial Co, whereas the MBRB1635CT-TP is classified as obsolete.

Regulatory Compliance: Both parts maintain identical REACH status (REACH Unaffected) and ECCN classification (EAR99), ensuring equivalent compliance posture for supply chain and export control requirements.

Electrical Compatibility: The substitute part provides a higher reverse voltage rating (45 V versus 35 V) while maintaining all other electrical parameters at identical specifications. This elevated voltage rating is compatible with applications designed for the original 35 V part and provides additional design margin in reverse voltage stress conditions.

Physical Compatibility: The MBRB1645CT-TP is packaged in the identical TO-263-3 D2PAK configuration, enabling direct board-level substitution without PCB redesign or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can the MBRB1645CT-TP be used as a direct replacement for the MBRB1635CT-TP in existing designs?

A: Yes. The MBRB1645CT-TP is electrically and mechanically compatible with the MBRB1635CT-TP. The substitute maintains identical forward voltage, current rating, switching speed, and operating temperature range. The higher reverse voltage rating (45 V versus 35 V) does not create incompatibility with designs specified for 35 V operation.

Q: What is the primary difference between these two parts?

A: The primary difference is the maximum reverse voltage rating. The MBRB1635CT-TP is rated for 35 V reverse voltage, while the MBRB1645CT-TP is rated for 45 V. All other electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between the MBRB1635CT-TP and MBRB1645CT-TP?

A: No. Both parts use the identical TO-263-3 D2PAK package with 2 leads plus tab configuration. Pinout and footprint are identical, enabling direct PCB substitution.

Q: What is the reverse leakage current specification for the MBRB1645CT-TP?

A: The reverse leakage current for the MBRB1645CT-TP is 100 µA at 45 V, which is identical to the MBRB1635CT-TP specification of 100 µA at 35 V.

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

A: No. The forward voltage specification remains 700 mV maximum at 8 A for both parts, indicating identical conduction characteristics.

Q: Are both parts compliant with REACH regulations?

A: Yes. Both the MBRB1635CT-TP and MBRB1645CT-TP maintain REACH Unaffected status, indicating equivalent regulatory compliance.
