UCC27201DRMT Equivalent & Substitute Parts

Part Overview

The UCC27201DRMT is a half-bridge gate driver IC manufactured by Texas Instruments, designed for driving N-channel MOSFETs in half-bridge configurations. This device operates with a supply voltage range of 8V to 17V and delivers peak output currents of 3A for both source and sink operations. The UCC27201DRMT is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent substitute parts is essential for design continuity and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCC27201DRMT is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology must be maintained
• Number of Drivers: Exactly 2 independent drivers required
• Gate Type: N-Channel MOSFET driving capability
• Voltage - Supply: 8V ~ 17V operating range
• Current - Peak Output: 3A source and 3A sink capability
• High Side Voltage - Max (Bootstrap): 120V maximum rating
• Rise / Fall Time: 8ns rise, 7ns fall time specifications
• Operating Temperature: -40°C ~ 140°C junction temperature range
• Package / Case: 8-VDFN Exposed Pad form factor
• Base Product Number: UCC27201 series designation

The UCC27201DRMR qualifies as a direct substitute based on identical electrical specifications and package configuration. The only distinction is packaging format: the main part uses Cut Tape (CT) while the substitute uses Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

The UCC27201DRMR is a direct electrical and mechanical equivalent to the UCC27201DRMT. Both parts share identical electrical specifications, thermal ratings, and package dimensions. The primary distinction is product lifecycle status: the UCC27201DRMT is designated Last Time Buy, while the UCC27201DRMR maintains Active status with significantly higher inventory availability (20,200 pcs vs. 2,300 pcs).

For new designs or long-term production requirements, the UCC27201DRMR is the recommended selection due to its active product status and superior supply chain availability. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The packaging format difference (Cut Tape vs. Tape & Reel) affects procurement and handling procedures but does not impact electrical performance or PCB assembly compatibility. Design teams should verify their assembly equipment specifications to confirm compatibility with the selected packaging format.

Frequently Asked Questions (FAQ)

Q: Can the UCC27201DRMR be used as a direct replacement for the UCC27201DRMT in existing designs?

A: Yes. The UCC27201DRMR is electrically and mechanically identical to the UCC27201DRMT. All electrical parameters, thermal specifications, and package dimensions are equivalent. No circuit modifications are required.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging provides individual component strips suitable for manual handling and small-quantity assembly. Tape & Reel packaging supplies components on continuous reels optimized for automated pick-and-place assembly equipment. Both formats contain identical components; the difference is in delivery and handling method.

Q: Why is the UCC27201DRMT listed as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part number variant. Existing inventory will be sold until depletion, after which the part will no longer be available. The UCC27201DRMR remains in active production as the recommended alternative.

Q: Are there any thermal or reliability differences between these two part numbers?

A: No. Both parts operate across the identical temperature range (-40°C ~ 140°C junction temperature) and share identical thermal characteristics. Reliability and lifespan expectations are equivalent.

Q: What inventory considerations should guide part selection?

A: The UCC27201DRMR offers substantially higher inventory availability (20,200 pcs) compared to the UCC27201DRMT (2,300 pcs). For production quantities exceeding available UCC27201DRMT stock, the UCC27201DRMR ensures supply continuity without design changes.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the UCC27201DRMT and UCC27201DRMR are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for environmental and hazardous substance restrictions.
