| FFF Compatibility | The pinout and package footprint are exactly identical to the original part, allowing it to be used as a direct drop-in replacement without board modifications.Both parts are housed in a 6-pin SOT-23 package sharing identical physical dimensions and mounting styles.All critical electrical ratings, output current capacity (500mA), operating temperature range, and control features (Enable, Power Good) are fully compatible. | The device uses a 5-pin SOT-23-5 package instead of a 6-pin SOT-23-6 package, necessitating a PCB layout redesign.Though both are SOT-23 series SMD packages, they differ in pin count (5 pins vs 6 pins) and physical landing pattern.Lacks the Power Good (POK) status output pin, which may impact system-level power sequencing if utilized on the target board. | ||
 AI Summary | MAX1818EUT18-T by Analog Devices: Linear Voltage Regulator IC Positive Adjustable (Fixed) 1 Output 500mA SOT-23-6. | This is the direct RoHS-compliant, lead-free counterpart to the original obsolete part. It is actively supported by the manufacturer and serves as a true drop-in replacement requiring absolutely zero design or layout changes.
| This alternative is an active 500mA 1.8V LDO from Microchip. It fits similar electrical profiles but requires a board redesign because it comes in a 5-pin package and lacks a Power Good (POK) signal.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Analog Devices MAX1818EUT18-T is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Analog Devices MAX1818EUT18-T are the MAX1818EUT18+T (Analog Devices Inc./Maxim Integrated) and the MIC5319-1.8YD5-TR (Microchip Technology), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the MAX1818EUT18-T are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The MAX1818EUT18-T (Analog Devices) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
