MP86963DUT-LF-Z Equivalent & Substitute Parts

Part Overview

The MP86963DUT-LF-Z is a half bridge driver IC designed for general purpose power MOSFET applications with a 20A output current capability. Manufactured by Monolithic Power Systems Inc., this component operates within a 4.5V to 5.5V supply voltage range and supports inductive loads up to 21V. The device features bootstrap circuit and diode emulation capabilities in an 18-pin surface mount package.

This part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. Substitute parts must maintain functional equivalence in half bridge driver topology, output current specifications, and voltage operating ranges.

Substitute Part Grouping Explanation

Substitute parts for the MP86963DUT-LF-Z are identified based on the following critical parameters that define functional equivalence:

• Output configuration: Half bridge driver topology
• Output current capability: 20A minimum per channel
• Supply voltage range: 4.5V to 5.5V compatibility
• Load voltage range: Support for 4.5V to 21V operation
• Operating temperature range: -40°C to 85°C
• Feature set: Bootstrap circuit and diode emulation capability
• Compliance standards: ROHS3 and REACH compliance

The MP86901-CGLT-Z meets these substitution criteria as an active product from the same manufacturer within the Intelli-Phase series, providing continued design support and production availability.

Engineering Selection Recommendations

The MP86901-CGLT-Z is the manufacturer-recommended substitute for the obsolete MP86963DUT-LF-Z. Selection of this substitute is supported by the following factors:

• Both components are manufactured by Monolithic Power Systems and belong to the Intelli-Phase driver family
• The MP86901-CGLT-Z maintains active product status, ensuring continued availability and technical support
• Both parts maintain identical ROHS3 compliance and REACH unaffected status
• Both components share the same export classification (EAR99) and tariff code (8542.39.0001)
• The substitute provides enhanced output current capability (25A versus 20A) and extended load voltage range (26V versus 21V), offering improved performance margins for existing designs

Frequently Asked Questions (FAQ)

Q: Can the MP86901-CGLT-Z directly replace the MP86963DUT-LF-Z in existing designs?

A: The MP86901-CGLT-Z is the manufacturer-recommended substitute and provides functional equivalence as a half bridge driver. The higher current rating (25A) and extended voltage range (26V) are compatible with applications designed for the original part. Physical package compatibility and PCB layout verification are required for direct board-level substitution.

Q: What is the primary reason for substitution?

A: The MP86963DUT-LF-Z is obsolete. The MP86901-CGLT-Z is an active product from the same manufacturer, ensuring continued supply chain availability and technical support.

Q: Are there compliance differences between the two parts?

A: No. Both components maintain identical ROHS3 compliance, REACH unaffected status, and export classification (EAR99). Regulatory requirements are equivalent.

Q: Does the higher current rating of the MP86901-CGLT-Z affect compatibility?

A: The 25A rating of the MP86901-CGLT-Z exceeds the 20A requirement of the original design, providing additional performance margin. This does not create incompatibility; applications designed for 20A operation remain fully supported.

Q: What package considerations apply to this substitution?

A: Package compatibility must be confirmed through detailed datasheet review and PCB layout assessment. Both components are surface mount devices; however, specific package dimensions and pin configurations require verification before board-level implementation.
