Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM25101CSD/NOPB is determined by the following critical parameters:

• Driven Configuration: Must be Half-Bridge
• Number of Drivers: Must be 2
• Gate Type: Must be N-Channel MOSFET
• Input Type: Must be Non-Inverting
• Package / Case: Must be 10-WDFN Exposed Pad
• Mounting Type: Must be Surface Mount

The UCC27201ADPRR qualifies as a manufacturer-recommended substitute. While it maintains identical functional architecture (half-bridge, dual independent N-channel drivers, non-inverting inputs, and identical packaging), it offers enhanced electrical performance characteristics including higher supply voltage tolerance (8V ~ 17V versus 9V ~ 14V), increased peak output current capability (3A versus 1A), and extended operating temperature range (-40°C ~ 140°C versus -40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

The UCC27201ADPRR is the manufacturer-recommended substitute for the LM25101CSD/NOPB. Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The LM25101CSD/NOPB is designated Last Time Buy, indicating production discontinuation. The UCC27201ADPRR maintains Active product status with significantly higher inventory availability (15,100 pieces versus 693 pieces), ensuring long-term supply chain continuity.

From a functional perspective, the UCC27201ADPRR provides superior electrical performance across all measured parameters while maintaining identical package geometry and pinout compatibility. The substitute part operates across a wider supply voltage range, delivers higher peak output currents, and supports extended operating temperatures. These enhancements ensure the substitute part functions reliably in all applications where the original part was specified.

Frequently Asked Questions (FAQ)

Q: Can the UCC27201ADPRR be used as a direct replacement for the LM25101CSD/NOPB?

A: Yes. Both devices share identical package geometry (10-WDFN Exposed Pad), pinout configuration, and functional architecture (half-bridge, dual independent N-channel drivers, non-inverting inputs). The UCC27201ADPRR provides enhanced electrical performance and is the manufacturer-recommended substitute.

Q: What are the key differences between these two parts?

A: The UCC27201ADPRR offers wider supply voltage tolerance (8V ~ 17V versus 9V ~ 14V), higher peak output current (3A versus 1A for both source and sink), higher maximum bootstrap voltage (120V versus 100V), faster rise and fall times (8ns/7ns versus 990ns/715ns), and extended operating temperature range (-40°C ~ 140°C versus -40°C ~ 125°C).

Q: Why is the LM25101CSD/NOPB being discontinued?

A: The LM25101CSD/NOPB is designated Last Time Buy, indicating Texas Instruments has discontinued production. The UCC27201ADPRR represents the recommended path forward for new designs and ongoing production requirements.

Q: Are there any compatibility concerns with PCB layout or thermal management?

A: Both parts use identical 10-WDFN Exposed Pad packaging with the same footprint and thermal pad dimensions. Existing PCB layouts require no modification for component substitution.

Q: What is the moisture sensitivity level difference?

A: The LM25101CSD/NOPB has MSL 1 (Unlimited), while the UCC27201ADPRR has MSL 2 (1 Year). Both are within standard handling and storage requirements for surface mount components.
