Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP592201DSCT are qualified based on the following criteria:

Parametric Equivalence Requirements:

• Output configuration: Positive adjustable
• Output current rating: 2A minimum
• Input voltage maximum: 6V or greater
• Output voltage range: Minimum 0.5V or lower, maximum 5V or higher
• Dropout voltage: 0.4V @ 2A or lower
• Operating temperature range: -40°C to 125°C or wider
• Package compatibility: 10-pin WFDFN with exposed pad
• Surface mount technology

Substitution Categories:

1. Parametric Equivalent (Direct Replacement): LP592201DSCR — Identical electrical specifications and package, same product status
2. Manufacturer Recommended Upgrade: TPS7A9201DSKT — Enhanced specifications with Active product status, improved availability, and additional protection features

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Product Status): LP592201DSCR is a parametric equivalent suitable for applications where product lifecycle status is not a constraint. Both LP592201DSCT and LP592201DSCR share identical electrical specifications, package dimensions, and "Not For New Designs" status. Selection between these two should be based on inventory availability and lead time requirements.

For New Designs and Long-Term Availability: TPS7A9201DSKT is the manufacturer-recommended upgrade path. This device carries Active product status, ensuring long-term availability and manufacturing support. It meets or exceeds all critical electrical parameters of the LP592201DSCT, including output current (2A), dropout voltage (0.4V @ 2A), and operating temperature range (-40°C to 125°C). The TPS7A9201DSKT provides enhanced input voltage tolerance (6.5V vs. 6V maximum) and expanded output voltage range (0.8V to 5.2V vs. 0.5V to 5V). Additional protection features include Over Current, Over Temperature, and Under Voltage Lockout (UVLO) compared to Short Circuit and Thermal Overload protection in the LP592201DSCT.

Package Consideration: The TPS7A9201DSKT uses a 10-SON (2.5x2.5) package versus the 10-WSON (3x3) package of the LP592201DSCT. Both are 10-pin WFDFN packages with exposed pads suitable for surface mount assembly. PCB layout modifications may be required due to the smaller footprint of the TPS7A9201DSKT.

Compliance and Certifications: All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can LP592201DSCR be used as a direct replacement for LP592201DSCT? A: Yes. LP592201DSCR is a parametric equivalent with identical electrical specifications, output current rating (2A), voltage ranges, dropout voltage, and package configuration. Both devices share the same "Not For New Designs" status. The primary difference is inventory availability.

Q: What are the key differences between LP592201DSCT and TPS7A9201DSKT? A: Both devices deliver 2A output current and maintain 0.4V dropout voltage at full load. TPS7A9201DSKT offers Active product status (versus "Not For New Designs"), higher input voltage tolerance (6.5V vs. 6V), expanded output voltage range (0.8V to 5.2V vs. 0.5V to 5V), and enhanced protection features including Over Current, Over Temperature, and UVLO. The TPS7A9201DSKT uses a smaller 10-SON (2.5x2.5) package footprint compared to the 10-WSON (3x3) package.

Q: Is the TPS7A9201DSKT pin-compatible with LP592201DSCT? A: Both devices use 10-pin WFDFN packages with exposed pads. However, the TPS7A9201DSKT has a smaller footprint (2.5x2.5mm vs. 3x3mm). PCB layout modifications are required for footprint accommodation, though pin assignments remain compatible for the core regulator function.

Q: Which substitute part should be selected for new product designs? A: TPS7A9201DSKT is the appropriate choice for new designs. It carries Active product status, ensuring long-term manufacturing support and availability. It meets all electrical requirements of the LP592201DSCT while providing enhanced protection features and improved input voltage tolerance.

Q: Are there any moisture sensitivity considerations when selecting a substitute? A: LP592201DSCT and LP592201DSCR have MSL 1 (Unlimited), while TPS7A9201DSKT has MSL 2 (1 Year). MSL 2 requires storage in controlled humidity conditions and has a one-year shelf life from the date of manufacture. This is a standard industry specification and does not affect functional performance.

Q: What is the impact of the different package sizes on PCB design? A: The TPS7A9201DSKT (2.5x2.5mm) has a smaller footprint than the LP592201DSCT (3x3mm). Designs using the TPS7A9201DSKT benefit from reduced board space. Existing PCB layouts designed for the LP592201DSCT require footprint modification to accommodate the TPS7A9201DSKT. The LP592201DSCR maintains the same 3x3mm footprint as the original part.
