Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP592201DSCR are identified based on the following critical parameters that determine functional and mechanical compatibility:

Core Electrical Parameters:

• Output configuration (Positive Adjustable)
• Output current capability (2A)
• Input voltage range (maximum 6V or higher)
• Output voltage range (0.5V to 5V or compatible range)
• Dropout voltage (0.4V @ 2A or lower)
• Control features (Enable, Power Good, Soft Start)

Mechanical & Environmental Parameters:

• Surface mount package type (10-WFDFN Exposed Pad or equivalent)
• Operating temperature range (-40°C ~ 125°C or wider)
• RoHS3 compliance
• Moisture sensitivity level

Substitutes are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications with different packaging) and manufacturer-recommended alternatives (enhanced specifications with active product status).

Parameter Comparison

Engineering Selection Recommendations

LP592201DSCT (Parametric Equivalent): This part is a direct parametric equivalent to the LP592201DSCR, offering identical electrical specifications and the same 10-WSON (3x3) package footprint. The only difference is the packaging format (Tape & Reel). Both parts carry "Not For New Designs" status and identical RoHS3 compliance and MSL ratings. Selection of this substitute is appropriate for direct replacement in existing production runs where inventory continuity is required.

TPS7A9201DSKR (Manufacturer-Recommended Alternative): This part is the active, manufacturer-recommended substitute for the LP592201DSCR. It maintains core electrical compatibility (2A output, 0.4V dropout @ 2A, Enable/Power Good/Soft Start features) while offering enhanced specifications: higher maximum input voltage (6.5V vs. 6V), extended output voltage range (0.8V to 5.2V), and additional protection features (Over Current, Over Temperature, Under Voltage Lockout). The TPS7A9201DSKR carries Active product status, ensuring long-term availability and support. The package footprint differs slightly (10-SON 2.5x2.5 vs. 10-WSON 3x3), requiring PCB layout verification. Quiescent current is higher (4.6 mA vs. 700 µA), and MSL rating is 2 (1 Year) versus 1 (Unlimited). This part is recommended for new designs and long-term production applications.

Frequently Asked Questions (FAQ)

Q: Can LP592201DSCT be used as a direct replacement for LP592201DSCR? A: Yes. LP592201DSCT is a parametric equivalent with identical electrical specifications, output current (2A), voltage ranges (0.5V to 5V), dropout voltage (0.4V @ 2A), and control features. Both use the same 10-WSON (3x3) package footprint. The only difference is packaging format (Tape & Reel). No circuit modifications are required.

Q: What are the key differences between LP592201DSCR and TPS7A9201DSKR? A: The TPS7A9201DSKR offers enhanced specifications: higher maximum input voltage (6.5V vs. 6V), wider output voltage range (0.8V to 5.2V vs. 0.5V to 5V), additional protection features (Over Current, Over Temperature, UVLO), and Active product status. The package footprint is slightly smaller (10-SON 2.5x2.5 vs. 10-WSON 3x3), requiring PCB layout verification. Quiescent current is higher (4.6 mA vs. 700 µA).

Q: Is TPS7A9201DSKR suitable for new designs? A: Yes. TPS7A9201DSKR carries Active product status and is the manufacturer-recommended alternative. It is suitable for new designs and provides long-term availability. Verify that the slightly smaller package footprint (10-SON 2.5x2.5) is compatible with your PCB layout.

Q: What is the impact of the different package sizes (10-WSON 3x3 vs. 10-SON 2.5x2.5)? A: Both packages use the same 10-WFDFN Exposed Pad case style and are surface mount compatible. However, the physical footprint differs: 10-WSON (3x3) is larger than 10-SON (2.5x2.5). PCB layout and thermal design must be verified for the TPS7A9201DSKR to ensure compatibility with existing designs.

Q: Are all three parts RoHS3 compliant? A: Yes. LP592201DSCR, LP592201DSCT, and TPS7A9201DSKR are all ROHS3 Compliant. All three parts are REACH Unaffected and carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts? A: LP592201DSCR and LP592201DSCT have MSL 1 (Unlimited shelf life). TPS7A9201DSKR has MSL 2 (1 Year shelf life). MSL 2 requires controlled storage conditions and has a one-year maximum shelf life from the date of manufacture if stored at 30°C and 85% relative humidity.

Q: Can I use TPS7A9201DSKR in place of LP592201DSCR without circuit modifications? A: Electrical compatibility is maintained for most applications due to matching output current (2A), dropout voltage (0.4V @ 2A), and control features. However, verify: (1) PCB layout compatibility with the smaller 10-SON (2.5x2.5) package, (2) thermal design adequacy given the same power dissipation, and (3) application tolerance for the higher quiescent current (4.6 mA vs. 700 µA) and different output voltage minimum (0.8V vs. 0.5V).
