For a BOM freeze in a production program, this part carries no near-term obsolescence risk. The AEC-Q100 qualification and automotive series designation mean the part is manufactured on a line that maintains long-term supply commitments typical of automotive-grade products. ## Closest functional alternative — LM53625LQURNLRQ1 When sourcing this part, the closest functional second-source candidate in the same family is the LM53625LQURNLRQ1. Both are AEC-Q100 qualified synchronous buck regulators in a wettable-flank QFN package. The LM53625 is fixed-output (5 V) and rated for 2.5 A, with a slightly higher input minimum of 3.9 V and a wider junction temperature range up to 150°C. The LMR33630APCQRNXRQ1 offers an adjustable output and 3 A capability. If your design requires an adjustable rail or the full 3 A, the LMR33630APCQRNXRQ1 is the correct choice; for a fixed 5 V, 2.5 A application with higher temperature tolerance, the LM53625LQURNLRQ1 is a valid drop-in after layout review (pinout may differ — verify the footprint).","metaTitle":"LMR33630APCQRNXRQ1 Automotive Buck Regulator, 3 A","metaDescription":"TI LMR33630APCQRNXRQ1 is an AEC-Q100 qualified synchronous buck regulator. 3.8 V to 36 V input, 3 A output, 2.1 MHz switching.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"12-VFQFN","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"2.1MHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"36V","Voltage - Input (Min)":"3.8V","Voltage - Output (Max)":"24V","Supplier Device Package":"12-VQFN-HR (3x2)","Voltage - Output (Min/Fixed)":"1V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.76","priceTiers":[{"qty":1,"price":"$2.76000","currency":"USD"},{"qty":10,"price":"$2.47600","currency":"USD"},{"qty":25,"price":"$2.33560","currency":"USD"},{"qty":100,"price":"$1.99000","currency":"USD"},{"qty":250,"price":"$1.86848","currency":"USD"},{"qty":500,"price":"$1.63494","currency":"USD"},{"qty":1000,"price":"$1.35466","currency":"USD"},{"qty":3000,"price":"$1.26124","currency":"USD"},{"qty":6000,"price":"$1.21453","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4d3746bebde726960da61fa30d700524.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMR33630APCQRNXRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is LMR33630APCQRNXRQ1 AEC-Q100 qualified?","answer":"Yes, the LMR33630APCQRNXRQ1 is qualified to AEC-Q100, as indicated by its Automotive series designation."},{"question":"What are the alternatives to LMR33630APCQRNXRQ1?","answer":"Within the same automotive family, the LM53625LQURNLRQ1 is a fixed 5 V, 2.5 A synchronous buck with a wider temperature range.
