Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC27210D is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Must be Half-Bridge
• Number of Drivers: Must be 2 independent channels
• Gate Type: Must drive N-Channel MOSFETs
• Supply Voltage Range: Must support 8V ~ 17V operation
• Logic Voltage Thresholds: Must match VIL 2.4V and VIH 5.8V
• Peak Output Current: Must deliver 4A source and 4A sink capability
• Input Type: Must be Non-Inverting
• Bootstrap Voltage Rating: Must support 120V maximum
• Package: Must be 8-SOIC form factor
• Compliance: Must maintain ROHS3 compliance and MSL Level 1

The UCC27210DR qualifies as a direct substitute based on identical electrical specifications and functional parameters. The primary distinction is packaging format: UCC27210D is supplied in Tube packaging, while UCC27210DR is supplied in Tape & Reel (TR) format. Both parts share the same base product number (UCC27210) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The UCC27210DR is a direct functional equivalent to the UCC27210D. Both parts are manufactured by Texas Instruments and maintain identical electrical and thermal specifications. The substitution is valid from an engineering perspective, with the only distinction being the packaging and delivery format.

Both parts carry Last Time Buy status, indicating that future availability from the manufacturer is limited. Both maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Selection between UCC27210D and UCC27210DR should be based on procurement requirements: Tube packaging (UCC27210D) is suitable for lower-volume applications or manual assembly processes, while Tape & Reel packaging (UCC27210DR) is optimized for high-volume automated assembly operations.

Frequently Asked Questions (FAQ)

Q: Can UCC27210DR be used as a direct replacement for UCC27210D in existing designs?

A: Yes. The UCC27210DR is electrically and functionally identical to the UCC27210D. Both parts deliver the same performance in half-bridge gate driver applications. The only difference is packaging format (Tube versus Tape & Reel).

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging (UCC27210D) supplies components in plastic tubes, typically used for lower-volume orders or manual assembly. Tape & Reel packaging (UCC27210DR) supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment in high-volume production.

Q: Are both parts ROHS3 compliant?

A: Yes. Both UCC27210D and UCC27210DR are ROHS3 compliant and carry MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions.

Q: Why are both parts marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has announced limited future availability for this product line. Customers requiring these parts should secure inventory accordingly.

Q: Do the parts require different PCB footprints?

A: No. Both parts use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). PCB footprints and land patterns are interchangeable.

Q: What is the bootstrap voltage rating used for?

A: The 120V bootstrap voltage rating specifies the maximum voltage that can be applied to the high-side gate driver circuit. This is typical for half-bridge topologies where the high-side MOSFET gate is driven relative to a floating source node.
