Key Parameters

Substitute Part Grouping Explanation

The SC4525FSETRT from Semtech Corporation qualifies as a substitute for the AP1530SDPG-13 based on the following critical parameters:

• Package Compatibility: Both parts utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring PCB layout and footprint compatibility
• Functional Category: Both are buck switching regulators classified as Power Management PMICs
• Mounting Type: Both employ surface mount technology
• Compliance Standards: The substitute maintains RoHS compliance and MSL Level 1 rating, meeting environmental and handling requirements

The SC4525FSETRT provides enhanced specifications including adjustable output voltage (1V to 16.74V), higher output current capability (3A), and a wider input voltage range (3V to 18V), making it suitable for applications previously served by the AP1530SDPG-13.
