Key Parameters

Substitute Part Grouping Explanation

Substitution of the MBR1535CT-BP is determined by the following critical parameters:

Configuration Match: The substitute part must maintain a 1 Pair Common Cathode diode array configuration to ensure pin-compatible operation within existing circuit topologies.

Technology Consistency: Schottky technology must be preserved to maintain fast recovery characteristics and forward voltage performance inherent to the original design.

Electrical Ratings: The substitute part must meet or exceed the voltage and current specifications of the original component. Reverse voltage rating must be ≥ 35 V, and average rectified current must be ≥ 15 A per diode.

Package Compatibility: The TO-220-3 through-hole package is mandatory for mechanical and thermal interface compatibility with existing PCB designs.

Temperature Range: Operating junction temperature range must encompass or exceed -55°C ~ 150°C to maintain functional equivalence across thermal operating conditions.

Engineering Selection Recommendations

The MBR1645CT-BP is the direct substitute for the obsolete MBR1535CT-BP. This substitution is valid based on the following engineering criteria:

Electrical Compatibility: The MBR1645CT-BP exceeds the electrical specifications of the MBR1535CT-BP. The 45 V reverse voltage rating provides 10 V additional margin over the original 35 V specification, and the 16 A current rating exceeds the original 15 A requirement. These enhancements ensure the substitute part operates within the design envelope of circuits originally specified for the MBR1535CT-BP.

Mechanical and Thermal Compatibility: Both parts utilize identical TO-220-3 through-hole packaging and share the same -55°C ~ 150°C operating temperature range, ensuring direct PCB mounting compatibility without design modification.

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 export classification, preserving compliance with applicable regulatory frameworks.

Product Status: The MBR1645CT-BP is classified as Active, ensuring continued availability and supply chain stability for new designs and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the MBR1645CT-BP be used as a direct replacement for the MBR1535CT-BP without PCB modifications?

A: Yes. Both parts share identical TO-220-3 package geometry and pin configuration. No PCB layout changes are required for mechanical or electrical interface compatibility.

Q: What is the significance of the higher voltage rating on the MBR1645CT-BP?

A: The MBR1645CT-BP is rated for 45 V reverse voltage compared to the MBR1535CT-BP's 35 V rating. This provides additional design margin and allows operation in circuits with higher transient voltage conditions. The substitute part remains fully compatible with circuits designed for the lower voltage specification.

Q: Are there any performance differences between these parts?

A: Both parts employ identical Schottky technology and fast recovery characteristics (≤ 500ns). The MBR1645CT-BP provides marginally higher current capacity (16 A versus 15 A) and voltage rating (45 V versus 35 V). Forward voltage characteristics are comparable across the specified operating range.

Q: Does the substitution affect thermal management?

A: Both parts utilize the TO-220-3 package with identical thermal interface characteristics. Thermal management design remains unchanged. The slightly higher current rating of the MBR1645CT-BP may result in marginally lower junction temperatures under equivalent load conditions.

Q: Are regulatory certifications maintained with this substitution?

A: Yes. Both parts maintain REACH Unaffected status and EAR99 export classification. No regulatory compliance changes result from this substitution.

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

A: The MBR1645CT-BP is classified as Active with 983 pieces in stock, ensuring reliable procurement for both new designs and production requirements.
